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 ?

restreaming with ffmpeg and ffserver
13 mars 2014, par DnasoI have been looking all over stack and the net and cannot find the answer (or one that works for me anyway). I have a cerevo liveshell pro which is a video encoder (pretty damn good too). In its RTSP server mode, I am able to watch audio and video on iphone and android. However, It can only hold 3 connections. I want to restream this stream NO encoding of any type on ffserver. Is this possible ? Everything I have tried so far does not open. If I disable my audio in the config file it works and if i disable video and just push audio it works, but both will not. Also I do not want to use ffmpeg if I do not have to because I am not re encoding the stream, since it is already encoded in the correct format, I just want to restream it !.
ffmpeg -i rtsp://xxx -vcodec copy -acodec copy http://lclhst:8090/feed1.ffm
<stream>
format rtp
videoCodec libx264
AudioCodec aac
I also have global headers for audio and video.
</stream>has anyone been able to fix or surpass the issue ?
