I have exactly the same issue on iPhone 5 and iOS simulator 6.1

[SEB-Appstore]

Same issue running the iOS7.0.4: no sound when playing sophie.mov
Any fix for this?

[kimjj81]

I have same error.
"http://www.wowza.com/_h264/BigBuckBunny_115k.mov" is sample movie.
It can't play sound.

The video taken by my camera is played sound well.
But I can't find any one.

I know there are some issues with sound. Unfortunately at the moment I do not have the free time to investigate this. I've put this up together for another project which was discontinued.

[SEB-Appstore]

By using these settings in the createAudioQueue method of the AudioStreamer:
switch (audioCodecContext->codec_id) {
...
case CODEC_ID_AAC:
{
audioStreamBasicDesc.mFormatID = kAudioFormatMPEG4AAC;
audioStreamBasicDesc_.mFormatFlags = kMPEG4Object_AAC_LC;
audioStreamBasicDesc_.mSampleRate = audioCodecContext->sample_rate;
audioStreamBasicDesc.mChannelsPerFrame = audioCodecContext->channels;
audioStreamBasicDesc.mBitsPerChannel = 0;
audioStreamBasicDesc_.mFramesPerPacket = audioCodecContext->frame_size;
audioStreamBasicDesc.mBytesPerPacket = 0;
audioStreamBasicDesc_.mBytesPerFrame=audioCodecContext->frame_bits;
audioStreamBasicDesc.mReserved=0;
NSLog(@"audio format %s (%d) is supported", _audioCodecContext->codec_descriptor-> name, _audioCodecContext->codec_id);
break;
}
...}
you can have the sound of the videos.
However, when settings the AudioQueue this way, the app crashes (when freeing some buffer) if you try to play the http://www.wowza.com/_h264/BigBuckBunny_115k.mov. The video with sound plays fine if you download it play it locally though....
After some tests using these settings, it seems that all local videos (videos saved in the documents folder) with sound are played fine, while the app crashes trying to play remote videos with sound as I haven't found a way to avoid the crash when freeing the buffer...

[durfu]

Thanks SEB-Appstore for the info.
About the crash, just from the top of my head, maybe it is something related to the sockets. I believe something is not correctly stopped in that area.

[SEB-Appstore]

To be more accurate, with the previous settings, the crash occurs in the while loop of the - (OSStatus)enqueueBuffer:(AudioQueueBufferRef)buffer method of the audiostreamer, at the av_free_packet(packet) line.

SEB-Appstore, thanks for fix!

[andrenatal]

I confirm this issue unfortunately still happen on iOS8 at iphone 4s with the latest commit 6c012d2

I can hear few seconds of audio and then stop play

[formoon]

same problem with SEB-Appstore

[maxcox]

I also have the same problem even after SEB-Appstore's fix

[erdemgc]
