handler_name : Core Media Data HandlerThe audio class that manage sounds contain a codec detector which say that the codec CODEC_ID_AAC is found for the two input :
audioStreamBasicDesc_.mFormatFlags = 0;
switch (_audioCodecContext->codec_id) {
case CODEC_ID_MP3:
audioStreamBasicDesc_.mFormatID = kAudioFormatMPEGLayer3;
break;
case CODEC_ID_AAC:
audioStreamBasicDesc_.mFormatID = kAudioFormatMPEG4AAC;
audioStreamBasicDesc_.mFormatFlags = kMPEG4Object_AAC_Main;
NSLog(@"audio format aac %s (%d) is supported", _audioCodecContext->codec_name, _audioCodecContext->codec_id);
break;
}I see data going into the buffer but i hear nothing. It's maybe audioStreamBasicDesc_ which has wrong settings but i can't find what.
Is it possible that it's not the same AAC codec ?
Has someone experienced the same issue ?
Any help are welcome, i'm on this problem since some days now.
Edit :
I have found a error that i had not before, i don't know how to resolve it. If i change audioStreamBasicDesc.mFramesPerPacket to 0 or divided by 2, the error message dissapear.AudioConverterNew returned 'fmt?'

FFMPEG unwanted rotation
5 mars 2015, par BenWhen I add a watermark image with a landscape orientation to a video that has a portrait orientation the video automatically rotates to landscape. How do I prevent this ? Also, the audio file isn’t being merged into the output. How can I include the audio.mp3 to be the sole audio track ?
