I am using Vitamio library into my project to play stream video.
It's worked fine on majority Android devices.
But on some devices, video quality is very bad (example: Samsung galaxy Y S5360, LG L-07C,...)
I am used:
mVideoView.setVideoURI(uri);
mVideoView.setVideoQuality(MediaPlayer.VIDEOQUALITY_HIGH);
mVideoView.getHolder().setFormat(PixelFormat.RGBX_8888);
but it's still not change.
Please help me.
I just found the answer.
Just put this line when initialising the VideoView:
mVideoView.setVideoChroma(MediaPlayer.VIDEOCHROMA_RGB565);
It looks like different pixel format of video and surface View.
Set mVideoView.setVideoChroma(MediaPlayer.VIDEOCHROMA_RGB565); and mVideoView.getHolder().setFormat(PixelFormat.RGB_565);

I have an app with a VideoView to display an MP4 file. Everything was working perfectly fine, on all devices and all Android versions, until Android 12.
We have one user reporting that the VideoView is unable to play the videos, for every video he gets the following popup (the app doesn't crash, just this popup is shown):
My question: does anyone know what the problem might be? I'm expecting - or hoping - it has to do with the fact that it's the beta version of Android 12. If that's not the case, then how can I solve this issue? Anything that changed for Android 12 w.r.t. displaying videos?
Many thanks.
EDIT: The video files are located in local storage (R.raw folder)
EDIT 2: When running the emulator with Android 12, I get the MediaPlyaer error (1, -2147483648). This corresponds to MediaPlayer.MEDIA_ERROR_UNKNOWN and UNKNOWN_ERROR respectively, as explained in this SO post. However, the proposed solutions there don't solve the problem here (the format should not be the issue, since they are .mp4 files). Any ideas?
EDIT 3: I submitted an issue with Google about this. If you're interested in a solution, star it here. Hope we can find the cause soon!
What fixed it was saving the video in AVC/H264 format and using that file.
From reporting this issue on Google's Issuetracker here, it turned out that the problem was actually with the encoding of the video files in this case. The video that wasn't playing was encoded in MPEG-4 format (.mp4) and exceeded the capabilities of the MPEG-4 software decoder.
I don't know why this wasn't an issue before Android 12 (videos were playing fine before), but at least this does fix the issue.
I have an app which shows live streaming of a channel. I was using HTTP at first but now I want to use RTSP because is is supposed to work on more devices. Anyway, my RTSP URI works fine on a 4.3 device. However it does not work on a 2.3.5 device. I only get audio and not video on the 2.3.5 device. Anyway I thought it was a codec problem, so I found a video that played well on both devices and compare their formats:
This is for the video that does not play:
This is for the video that plays well:
I cannot see why one plays fine and one only plays the audio. I think is not a code problem as I have been using any possible solution I could find online.
I solved the issue. The problem was the resolution of the videos; All devices support up to 480 x 360 px in SD and only some of the devices support up to 1280 x 720 px in HD.
I am working with html5 video tag, i am using .m3u8 file for source. I can not able to seek video by using currentTime property in android 4+ whereas if i using .mp4 file i can able to seek.
In ipad its working properly but not working in android. Please guide me to rectify this issue.
Thanks,

HLS and Android are not the best of friends.
Some problems I know of are:
No adaptive bitrate switching: the first quality is picked, no switching will occur.
When pausing, the video restarts from the beginning (for example with VOD).
When going fullscreen, the video restarts from the beginning.
When offering a livestream with DVR, the stream starts at the beginning of the DVR instead of at the "live" moment.
You cannot seek. <-- this is the one for you
Aspect ratio's are not detected properly. (tho this should be fixed in 4.1)
On top of these problems, there is no support for HLS in pre 2.3 Android and in 3.0 it actually makes your tablet crash.
Basically: only use HLS on Android for live video without DVR and set the correct aspect ratio. Oh, and try to pick a "suitable" quality, cause it won't switch.
I've been struggling to make VideoView work with mp4 files. The thing is that with some mp4 files (that have lower resolution) it works, but in case of higher resolution 480x268 it rejects to play. This issue resembles me the same situation here. It's said that Android can only play mp4 files below certain resolution. Does it holds for today ?
P.S. I'm building against Android 2.3.
Thanks.
did u add the hardware support while creating the emulator for playing video and audio. Maybe thats y it isnt working
I've searched all over for a solution to this (including SO), however still haven't found a solution.
I need to have a simple video playback in my app. It's a bit less straightforward than a simple window with a video. Simplified, I have two layouts on my screen, one containing some other stuff and the other is to have the video window. There's also a button to switch between the two. This all works just fine, after I figured out that the videoview cannot be present on a view with visibility 'gone' - therefore I'm adding/removing it to/from container layout when needed.
However, I have the problem with the actual video playback. When I try to activate it, I get the dreaded error Sorry, this video cannot be played. One of the questions here on SO is discussing video formats (Android -- Can't play any videos (mp4/mov/3gp/etc.)?) - however I already have what seems to be the correct format, with 320px width and everything else. One of the answers on that thread mentions that videos from here "definitely work". I tried a couple from there - but I got another common beast: Sorry, this video is not valid for streaming to this device.
Please note that I'm testing on an actual device, as video playback is not working in the emulator. Also note that the solution must work on Android 1.6 and above (client's requirement). The device I'm testing on is LG GT540 Optimus with Android 2.1 (at present I don't have any other devices available).
From what I figured out, if I don't use qt-faststart on the videos, I get error Sorry, this video is not valid for streaming to this device. If I do use qt-faststart, then I get Sorry, this video cannot be played.
Here's my code for the playback:
VideoViewer videoPlayer = new VideoViewer(this);
MediaController mediaController = new MediaController(this);
mediaController.setAnchorView(videoPlayer);
videoPlayer.setMediaController(mediaController);
videoPlayer.setVideoURI(Uri.parse(object.getVideoURL()));
LinearLayout container = (LinearLayout)ObjectInfo.this.findViewById(R.id.VideoContainer);
container.setVisibility(VISIBLE);
container.addView(videoPlayer, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
videoPlayer.requestFocus();
videoPlayer.start();
Now, the video I'm trying to play is to be progressive-downloaded from HTTP: object.getVideoURL() returns http://www.ooklnet.com/files/381/381489/video.mp4
Can anybody please help me sort this out? This is the last thing I need to complete before the whole app is ready.
Many thanks!
Edit: I tried using MediaPlayer - but got even worse results than with VideoView, so went back to VideoView. Now, in simulator, I get a black screen with controls hovering over it and the sound of the video is playing fine, also the progress is adjusting as the playback continues. However on my actual device, I'm still getting Sorry, this video cannot be played. error
Turned out the problem was with the format of the videos (specifically, the parameters I used with ffmpeg to create the MP4 videos). I ensured that the videos are baseline H.264 - and everything worked properly. See this question for more details.
Maybe you need to change the way you set up your MediaPlayer. I just plugged the url of your sample video into the apidemos example and it worked just fine.
See:

Hope that helps.
