I am having issues streaming movies wirelessly. I can connect to my TV using wifi and stream music, but when I try to do the same with the movies, I get an error message. Am I doing something wrong? I downloaded DivX movies, avi, and none work. What am I doing wrong?
You gotta give us some more details in order to help you out. What method are you using to try and stream movies? What does the error msg your getting say?
Streaming
First going to a Gallery. Selecting a Video. After clicking on a menu, and it gives you 3 options Trim, Select player, and Play in 3D.
Don't remember the exact error since I'm not at home at the current moment, but it pretty much says that this type of a file is not supported.
Common issue is that the program may not support that specific file type... There are a lot of ways to end up with a .avi file, some work better then others...
Try a .mpg or .mpeg ... If those types play fine, Its the file, If they don't either... Hard Reset. (most likely a jacked up codec or damaged media player program on the phone)
I have downloaded video formats .mpg and .mpeg
Did a Hard Reset, and still unable to stream
I get a message "The player is unable to play this type of file"
I don't know what else to do.
I have had 100% success with .mp4 movies. Try encoding your videos with Wondershare or Handbrake using the H.264 codec (Best Quality) IMO.
Keep the files below 2GB - EVO doesn't like them any bigger. (could that be your issue? Are you trying to play files that are larger than 2GB?)
No, the movie is 1.95 GB.
I just want to be able to stream it without converting anything, from my phone on to my TV. (I have a SONY LED 3D 55" TV)
I even tried my PS3, and that didn't work. Maybe there is an app that streams any format?
Make sure ur tv has DLNA, that's how its streams it. If ur tv doesn't have it then it won't work

I can stream some formats of music and pictures, so I'm assuming if I can stream those, then my TV is capable for DLNA?

The 2GB issue is not that the Evo doesn't like it, it is a limitation of FAT32.
Not really sure what other file systems the phone will read, but if it supports ext2/ext3/ext4 then you shouldn't have the file size limitation any more.
Then I would search the market for vid players that play all formats and try again. I believe arc media does

The 2GB limitation is currently a limitation of Android. FAT32 has a 4GB limitation.
There are bugs already posted about the 2GB limitation of Android.
I'm having another issue. A couple days ago I could see my pc under devices named daniel-pc. Click on that (I'm within the music app trying to simply stream music from my shared folder on my computer) and I was receiving an error message saying something to the effect of I do not have permission to access this... Please allow access and try again. I don't remember the exact wording and I will post about that when I can get to it.
For now I have a different issue. I am connected to my wifi, I go to the music app hit the top evo 3d thing or menu -> select player and it simply buffers for a min then does not find my damn pc for some reason. I did a factory reset, no dice, hooked up via cable, ditto. I Updated profile and prl. I Did absolutely nothing different to my computer or router settings. I Updated my router firmware after not working which also did not help.
Btw my xbox which is hooked up via ethernet finds and plays daniel-pc just fine. My computer is not wifi its using ethernet to get to the router. As I sed earlier I could see my pc when going to select player so that isn't the issue. Thanks ahead. First post sorry for the length.
have u tried the media share app on the phone if that didnt work try tversity for your computer instead of your phone.
Media share works fine. As soon as I turn it on htc media share pops up on the left side of wmp. I can pull up my media from my phone easily. I'm trying to do the opposite and play files from my pc on my phone using the select player option. You can find this also by opening a picture up pressing menu then select player. if your on wifi now your computer should show up. At least that's what it used to do

1) Go to here to download AndroStream
2) Download and install the AndroVLC media server on the PC that hosts the .avi files
3) Ensure firewall is set up to allow AndroVLC or disable Windows Firewall
4) Reboot PC (starts up the media server)
5) Download AndroStream-Free from the Android market
6) Use Astro to back-up the AndroStream .apk (I would post the .apk but can't yet on these forums, some one else may be able to post it)
6) Install AndroStream app on your NC. There is a free version to use to get everything working and try out (limited to 2 minutes of playback). The paid version will let you watch entire movies.
6) Run AndroStream on your NC
7) Input the IP address of the host computer in the AndroStream settings
8) Hit the scan button to find the PC. Navigate to your folder with .avi files
7) Watch your streamed .avi files over your wifi at home on your personal 7" viewer
These are the only notes/issues I had:
I did this on an Windows XP machine
It also played .mp4 files fine, but would not play .wmv or .mkv files
Some audio lag, but could be due to the fact I was skipping around the movie to see how well it buffered.
I only tried with Standard Def Xvid .avi files, I did not try any HD
The AndroStream app on the Nook was very simple and quite fast to navigate to your media files on the PC
The movies go full screen and I wasn't able to get out of them easily. I have SoftKeys installed and hitting the nook button took me back to the home screen while using the AndroStream software, so I could not get back to select a different file to watch.
I am looking for other possibly better alternatives to this (different apps on the Nook or solving some of the above issues), because I like the idea of streaming video to my device over wi-fi. Hopefully other folks can provide some input or other apps or methods.
I've been using VLC Stream & Convert. All it needs on the server is VLC running with a web interface.
It converts the video before streaming, so you should be able to play more than mp4 files with it, but I can specifically remember if I've tried an mkv or wmv. The movies only went full screen in landscape mode, if you switched back to portrait the menu comes back for you to pick another file.
Can you put down exactly what you are doing? I tried using VLC and VLC Stream & Convert, but it isn't working. I am controlling VLC on the PC, but only audio is coming through to the NC. Not sure exactly how to set it up to work. Any ideas?
Thanks for this. I couldn't find the app the OP mentioned, but VLC Stream & Convert seems to do the trick.
VLC Stream and Convert
How were you able to get VLC S&C to work? Whenever I try to play on my NC I get an error: "Cannot create play command". I've tried .mkv, .avi, .mp3 and none seem to work. I'm only using a rooted NC, not a Froyo'ed version. Any suggestions would be greatful!
Edit:
I was able to get it working. Had to change the play mode. Sorry for posting the noobish question!
If you are still on stock, eclair, you can stream anything with this method,
http://iamafanof.wordpress.com/2010/12/27/streaming-epub-books-media-to-nook-color-with-cifsmanager/
BTW, you can do read/write from your NC to your computer if you change the permission settings.
No cifs module for Froyo and CM7 yet .
Ok so i got vlc to work playing avi files, only problem is that I keep getting small videos. What settings do you have?
ok nvm I got the sizing to work

I tried wmv and it works. What res are you guys running, the max 480 width in the free version? Has anybody bought the pro version and tried 640 width to see how it works? It would be cool if we could get the max 854 width that the NC supports for higher def files. I can stream 480 at max bit rate and only get a hiccup every few minutes, so I'm thinking higher res will be possible if you play with the bitrate some.

I was able to get full screen working on the free version, the trick is to override your video settings with the General Settings.
Go to Playback under General, then change landscape video width to fit screen. Make sure this is the last setting you change before playing the video.
You can use PS3 Meadia Server --> UPnPlay
You may want to try PS3 Media Server and UPnPlay in NC. It is running well in Customized Nook Froyo.
I have been using File Expert in combination with RockPlayer lite . File expert has a network tab which allows me to see all my files on my nas server. Which streams directly to my N/C using Rockplayer lite . Streams avi files directly no need to convert . Thanks Jamus0 for this tip .

I've got that set, but it's still stretching a 480 pixel wide video across the screen (which is fine, it works and looks pretty good). I was just wondering if anyone had gotten the pro version and tried 640 wide video, or if it lets you actually do 854 wide video to get the max res the NC supports in hardware.

I tried this method and got it to work once in Phiremod for my Nook. After that once successful stream it wouldn't work anymore. It would just give me an error saying 'System Player can't play this file'. Any suggestions what it may be? I have been looking for a solution for this and don't know if it's the default Android player that is giving me this error? How can I make RockPlayer lite the default player?
I've been using plex and works well.. i've also used cifs manager to map to my media server and watch movies through rockplayer.
I want to stream AVI files from my computer to my Nook. GMote doesn't work with AVI. I downloaded VLC Stream and Convert. I fired it up, pointed it at my desktop and it just worked. I was very impressed with it except that it streams all my videos in 4" X 4". I'm sure this would be great on a phone, but I've got 7" to work with here.
Does anyone know of an app that will reliably stream media in full screen? I'm willing to pay for an app that does this. I just need to stream over wifi when I'm at home.
I use CifsManager to mount windows shares, and then RockPlayer Lite to play videos off those shares. It will stretch to full screen, but unless you format the video correctly it's stuck with software decoding.
GMote plays AVI for me, do you have rockplayer?
No Rockplayer. I don't want to have to mount shares. It's an extra step. VLC Stream and Convert works perfectly except it's small screen. I open the app, click on browse, browse to the file I want to play and click play. It buffers and plays with no issues except for the screen size.
There's no extra steps, you browse to the avi you want to play in gmote, click it and rockplayer opens it.
I tested out the GMote Rockplayer combo you all suggested. It worked very well, except I can't seem to fast forward and skip around inside of videos. Is this something I"m doing wrong or is it a limitation of this solution?

I think it may be a limitation. If there's a fix, I don't know it. Rockplayer by itself allows skipping around but youve got it streaming the video through GMote and I doubt that Rockplayer is communicating to GMote.
I got this to work with VLC Stream and Convert. There are options buried in the menu to make the output full screen. I love it. I have to start VLC on my computer ahead of time which is kind of a pain, but I'm at home anyway when I'm doing this. Once I do though, I can stream any of my media and also fast forward, rewind and skip around in it whether in portrait or landscape. Highly recommend this.
I was hoping to provide a solution using orb or Androrb, but I tried with mplayer, rockplayer, and stock player with no luck.
Gmote/rockplayer works for me, but no ff as mentioned. If the v player dev could support the nc it may have potential.
To the above poster, you could use teamviewer to log in to your pc and start the vlc stream.

I suspect that Gmote/Rockplayer doesn't have FF because it's not accessing the stream directly. Gmote is accessing the stream and forwarding it to Rockplayer. I'm in my house when I'm using my NC and I have a VLC shortcut on my toolbar so it doesn't take but a second to start it. I could probably configure VLC to start the web interface part automatically when Windows starts, but I'm too lazy to look into that right now.

Does this require you to be on the same network as Said PC for it to work, ie, can I stream Video from home PC when I am in another area, like the mall, or your moms house?

VLC convert and stream allows this, yes.

I tried the same thing, works great in rooted Eclair but not in any of the CM7 versions. I think it is because there is no DSP working in CM7, but I could be wrong.

I've installed mobo player.
i've just put on avatar, transformers 3 and warrior. as i dragged them across the pc started converting them. each of them looked ok in the folder. when i unplugged the phone and tried playing them they were just about 5 minutes long with just a bit of music.
i'm completely stuck and baffled...
just tried again, and again, only 4 minutes 51 secs of video played. i don't understand why. is it because i'm uploading using my pc?
why is the pc trying to convert my file format as i'm trying to transfer it? confused!!!
I play 720p mp4 flawlessly with Mvideoplayer. I wasn't promted to convert my MP4 files when I copied them from my PC to my phone, but it did come up when I did it with some AVI files. I clicked no to conversion and they play fine on my phone.
OK, so i've now tried loading another type of file, avi, to the phone. it was a 6.2GB movie. It didn't load, said it was too big!!! WTF!
this is some FAT32 issue right?
But this still doesn't solve my original problem.
I've loaded many different files, many types, different sizes.... But it seems like all the stock video player (and now MOBO Player) wants to do is play only 4 minutes 51 seconds........
but when you look at the file through astro or the pc, it shows the true length of the file.... thnk i'm missing something here, it may be basic, but please help someone. been at this all day with no luck!!
wmv
anybody knows about a player for wmv files? I tried using the Mx Video Player but it says it doesn't support it.
I don't whether you guys looking for the free or paid apps
but
I personally using rockplayer lite and it does work with almost every thing especially if you use "play with hardware acceleration" then every thinh up to 3.5 gb film is work pefectly
I got also a PowerDVD mobile (violation of the xda ...) hacked one so it work well.
so i cannnot post a apk.

I transferred movies onto mine, six files ranging from about 700mb to 1.6gb in avi format and they play without any problems on mobo player,I also have power dvd mobile legit version and that plays them as well, the only thing I find with power dvd is it stops playing now and again and I have to press play for it to continue.
I'm on windows 7 and that asks me do I want to convert it,I don't generally but with the planet of the apes I did but it played ok just a smaller file size.
The only thing I can suggest if you haven't already done so is instead of drag and drop, try right clicking on the file and copy/paste and see if that makes a difference??

i tried like mx video player. mobo player etc almost anything with neon codec support. it can barely play a 720p wmv properly, audio just out of sync and video is laggy. something is not right here. however i try some other resolution like 480p and it works fine.
my ex optimus 3d can even play almost all video format with hardware acceleration support.
some media players does not use hardware acceleration!! thats is way is not work fluently

This was the kind of answer I was looking for.

I will try avi files, and no to convert.

Hi,
What is the best program to play movies and subtitles for XPS?
If you try to copy videos or audio it will sometimes ask you to format the file, simply don't allow this when the window pops up.
This will be different for every computer depending on what codecs you have installed.
Also sounds like your possibly not waiting long enough for the files to copy over? Might not be showing the progress bar for what ever reason, slow pc?
Replace the miniUSB cable perhaps with another.
Try a different computer to drag and drop the files across.
There's a 2gb file size limit with the fat file system, a 720p or lower avi movie that's about 700mb is plenty quality for a screen this small, you don't need large blueray 1080p clips taking up memory for a very minor difference in quality.
Sent from my LT26i using xda premium
Also you can put files anywhere on the memory, player will pick up the files automatically.
Sent from my LT26i using xda premium
If you use a combination of bubbleupnp and dice player you can play almost all movie formats just fine. It is perfectly possible to play videos from other dlna servers as well as play videos from the phone on other dlna renderers.

instead of converting you can try using mx video player from market, it has support for all types of subtitles
That's a good idea, and I will probably go with that - however at the moment I'm wanting to show off the features of my new phone to work colleagues, and popup play (although it's a gimmick) seems to impress! So I want to use the standard built in video player for that reason
Any suggestions? Is it even possible to combins .mkv & .srt into one file? I'm pretty ignorant when it comes to audiovisual stuff :-D

I tried using that and it seemed to be doing the job ok - (using the associated program MKVExtractGUI) it allows you to select the elements of video/sound/subs you want.
However the H264 file it spat out at the end won't play properly in VLC on my computer - it's jerky, jumping up and down from about 8 frames per second to 25fps and back again, lots of artifacts, and no sound or subtitles (despite me selecting those elements to be included).
If it barely plays in VLC on my laptop I doubt it's going to play on my phone...
Any more ideas?
Have you tried using the stock video player? It plays MKVs and subtitles out the box.
I tried that, that would be ideal - but it didn't play the mkv files i gave it. I'll try a couple of others and report back...
Ok well I've just found the first chink in this phone's armour:
It's very fussy about the .mkv files it will play.
It outright refuses some. Others it will play the video but no audio. Some it will play perfectly, unless you try and activate subtitles under the settings menu, in which case it craps out, freezes, and gives me a "this video cannot be played message." Even if I do manage to get it to play subtitles along with the video and audio, it's well out of sync - like minutes out of sync....

Well if you do have to end up re-encoding your videos, try out Format Factory. It's free and has a ton of options.
I would suggest using MP4 and 'burning in' the subtitles. If you can't understand the the language you might as well have them a part of the video.
Thanks, I'll give that a try
Ok here is the problem I am having. Im using my PC in my office as a media server. I am able to connect with my DNA and pull up all my videos with ease. Thing is not all my videos are in .mp4 format majority are in .avi. I am able to see the thumbnails of the videos but when I play them it says cannot be played. So on the side there is an option where you can search for wifi players. Tried that and even though I have video apps like mobo, vlc, and mx video installed. HTC doesn't recognize these options as wifi players. So should I convert these movies to .mp4? Im trying not to because most are HD movies over a gig each.

Clear the defaults for your stock video player and tap on the movie you want while using a file explorer then pick what player you want. The player option is for you to stream from your phone to a device that can hande the format, not an app on your phone.
