I have searched high and low, and nowhere can I find if newer Android/iOS devices ship with media players that can stream media (with the following characteristics) from inside an app:
Streaming MPEG-TS over UDP/IP
Video using h.264 codec
Audio using AAC codec
Is this even possible? If not, why (is the container incompatible, or some other reason)? If so, how (what software/media player do they need)? If it is possible, I need a way to open that media player from inside the app, but have no idea how to do that. Thanks in advance.

I have to get video/audio tracks or if it's possible MediaStream object from the Android WebView which plays HLS stream ("m3m8").
I load HLS stream in the WebView using method loadUrl("...m3m8"). It's running without issues, but i can't figure out how to get live video and audio tracks from the HLS stream. I read a lot of articles and I was not able to find any solution. So my question is - Is it possible to get audio and video tracks from the running HLS stream on the WebView? I need to get the audio and video tracks because I should send them via PeerConnection(WebRTC) which accepts MediaStream or audio tracks and video tracks. Any ideas and examples will be helpful. Thank you in advance.
HLS works by defining a playlist (your .m3u8 file) which points to chunks of the video (say segment00000.ts, segment00001.ts, ...). It can contain different streams for different resolutions, but the idea (very simplified) is that your player can download a chunk, play it right away, and download the next one in the meantime.
A WebRTC video track takes RTP packets. I don't know exactly what the Android API exposes, but it feels like either you can pass it an m3u8 as a source (though that may be a bit weird for a generic API), or you can't, and you have to read the HLS stream yourself, extract RTP frames, and pass them to WebRTC.
For instance, gstreamer's hlsdemux seems to be able to read from an HLS source. From there you could extract RTP frames and feed them to your WebRTC track.
Probably that's a bit lower-level than you hoped, but if the Android API doesn't do it for you, you have to do it yourself (or find a library that does it).
I am currently developing a video streaming feature for one of my android apps. I am using android media framework for the purpose. Videos are streamed from an nginx server. Android recorded videos works fine but iOS recorded videos plays only the video not the sound.
It happens because the android support limited codecs in-built like mp3,mp4,mpeg.
While iphone support most of codecs.
What is the way to resolve this?
MP4 for video and MP3 for audio are widely accepted and work on both platforms.
So you need do some stuff at the server. Implement the ffmpeg library that will convert all the videos to MP4 and audio to MP3.
We are doing same mechanism to resolve this issue.

Hope This may help you to get the rid of your problem
Happy Coding!
I'm developing an Android application that allow the users to watch the tv channels via streaming.
The user must "tap" on the channel (for example chan 1) and an activity show the real time video, but I have one question, there are other solutions, different by the use of a webview to show the live video ?
Exist some solutions more "professional" or functionals?
You can use ExoPlayer to play streams. Take a look at the DemoApp. As official documentation says
ExoPlayer has support for Dynamic Adaptive Streaming over HTTP (DASH)
and SmoothStreaming, neither of which are are supported by MediaPlayer
(it also supports HTTP Live Streaming (HLS), MP4, MP3, WebM, M4A,
MPEG-TS and AAC).
But make sure you can get the direct link to your streams.
I would like to show some video in my android application.
Video are like: http://myserver.com/video/myvideo.mov All the video are in .mov and some in .flv.
.mov have H264 - MPEG-4 AVC (avc1) video channel, and MPEG ACC Audio (mp4a) audio channel.
.flv have Flash Video (flv1) video channel, and MPEG Audio layer 1/2/3 (mpga) audio channel.
If I play the .mov with the default android player I can see the video image, but I can't hear anithing.
With the .flv I can see and hear the file in the default android player.
Is there a way to play correctly the .mov with the MPEG ACC Audio (mp4a) audio channel?
Anyone know if there is a custom library to play this .mov files? Thank you in advance!
As stated here MOV container even with H264/AAC inside is not supported in Android. The underlying reason is that MOV (aka quicktime file format) is a proprietary container from Apple (it is a close one from MP4 but still not the same) - most of the time it works 100% only on Apple device and/or quicktime player.
FLV container from Adobe is also not supported in Android (FLV can be packed with H263 or H264 video inside).
It can work on some device but as you experienced it, it can be clunky and surely inconsistent across devices.
Your best bet is to package/transcode your file in a format where you know you will have cross-Android compatibility.
If you want it badly you could think about building your own video player/decoder to play back mov/flv files (like with ffmpeg) but it is an advanced project in itself and providing code for that would be outside of the scope of stackoverflow - maybe have a look here.
I am trying to play a video in android native code using new API mediacodec. I dont want to go mediaPlayer way due to unavoidable reasons. can anybody share some code snippet as to how to go about it? Thanks in advance.
Your original question is too generic. And to be honest, create a new media player in native code is a huge task for your own.
If you are only seeking for some media player solution which has better supporting for variety of formats/codecs like VLC player, you can either try VLC lib which is open source but still in beta release. I have tried VLC, but it really has some crash issues or ANR issues, which is inside the whole framework.
Or you can try with Vitamio SDK which is a library without souce code. Check it out at this link: https://github.com/yixia/VitamioBundle Below is the feature list of it:
I have tried this solution, it is very stable, also some minor issue on 4.3, but still acceptable. So I am not posting any spam here, just copying from the official document:
