Xamarin android ffmpeg9/12/2023 ![]() ![]() So, I searched for the only way I knew how to encode a video that is by using FFmpeg codec. I've found encoding to be a bit complicated and there isn't much information available on how this can be done. ![]() I then decided to encode the video on the client-side and then send it to the server. I have posted my issues on another thread here Initially, I was using an encoder library on the server-side to encode recorded video but it was proving to be extremely unreliable and inefficient especially for large-sized video files. The requirement of the app is to capture video from the camera and encode the video to send it across to a server. I'm building an android app using Xamarin. Configure ( format, null, null, 0 ) decoder. SetByteBuffer ( "csd-0", csd ) // cbk is your callback class decoder. int profile = ( csd_data & 0xC0 ) > 6 int srate = ( csd_data & 0x3C ) > 2 int channel = (( csd_data & 0x01 ) > 6 ) byte csd0_0 = ( byte )((( profile + 1 ) > 1 ) byte csd0_1 = ( byte )((( srate << 7 ) & 0x80 ) | channel << 3 ) byte bytes = new byte ByteBuffer csd = ByteBuffer. ![]() you should pass first adts frame to InputBuffer with header (first 7 bytes). this data is exist head of stream (= stdout of ffmpeg.exe) // this 7 bytes is adts fixed header of first frame but you should not removed it from frame. CreateAudioFormat ( "audio/mp4a-latm", samplingRate, ch ) // IMPORTANT: csd_data is byte array (7 elements). CreateDecoderByType ( "audio/mp4a-latm" ) // samplingRate and ch is your required value var format = MediaFormat. Start () Handler handler = new Handler ( callbackThread. HandlerThread callbackThread = new HandlerThread ( "AACDecodingHandler" ) callbackThread. ![]()
