Save RTP audio to file: RTP Stream Analysis dialog allows save audio for non G.711 codecs and mixed codecs
- spaghetti code for save was split into separate functions
- code saves G.711 only, all other codecs are saved as silence with correct duration
- code is ready to include other codecs
- code supports 8000 Hz sampling rate only, other rates are rejected with warning
- bidirectional stream (forward and reverse) creates stereo .au file
- output is based on timestamps in RTP streams
- save operation is slower than before because it is set of seek() - one per each codec sample
- code allows align of save audio:
- as it is - each stream is saved from its beginning, no aling
- to start of each other - later stream is prepended with silence
- align saved audio to beginning of capture file - each stream is prepended with silence
- save to raw works correctly now - only payload is saved
- old code was inserting G.711 silence time to time to raw data
