Hi all!
I was trying to write an application based on SEMS 1.5.0, that would
record the incoming RTP stream into an audiofile.
I wanted to use wav with PCMA subtype ("wav|A-law"), but here is what I
have experienced:
The format type field in the wave header changed to WAV_ALAW (6), but
the payload failed to be set accordingly. It remained PCM16. I
investigated a little bit and found that somehow a getCodec() call gets
in before the subtype gets to be set.
(AmAudioFile.cpp:AmAudioFileFormat::AmAudioFileFormat) And that already
sets the codec to PCM16.
I did not get to the root of the problem, but I'm attaching a quickfix
for this.
Bests,
Tibor Karakó
