[Live-devel] AAC RTP problem (crackling sound)

Hello,

I'm using live555 in a swift (iOS) application, and I would like to stream
AAC through this phone using RTP.

I have done a lot of test using MP3 and it works fine. (I'm using VLC
and/or WireShark to capture the stream)

But I can't use AAC.

I tried to use ADTSAudioFileSource and MPEG4GenericRTPSink but I get a
crackling sound instead (Noise) when I try to capture it.

sessionStateAAC.source = ADTSAudioFileSource::createNew(*env, inputFileNameAAC);

sessionStateAAC.sink = MPEG4GenericRTPSink::createNew(*env,
sessionStateAAC.rtpGroupsock, 96, 44100, "audio",
"AAC-hbr",sessionStateAAC.source->configStr(),2);


How can I get rid of this problem ? Am I doing it wrong ?


Thanks, we are trying to get it work since 3 (working) days now
