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 Bug: 13242 Change-Id: I74d02a1cc1c75acf9ffe930d078c00a0555cbfb6 Reviewed-on: https://code.wireshark.org/review/19245 Petri-Dish: Anders Broman <a.broman58@gmail.com> Tested-by: Petri Dish Buildbot <buildbot-no-reply@wireshark.org> Reviewed-by: Anders Broman <a.broman58@gmail.com>
