Hello everyone Because Opus is a totally open audio codec and very useful, I want to make WireShark support Opus so that the WireShark can play Opus audio RTP stream and save. Ihadsomeattempts.PuttheOpusintotheplugins/codecs. NowWireSharkcanplayandsaveOpusaudioRTPstreamliketheg711, g722. TosupportOpusandFEC(ForwardErrorCorrection), Ichangedsomecode: Here is the change: 1、Change a function with C++ default parameters Origin version: size_t convert_payload_to_samples(unsigned int payload_type, QTemporaryFile *tempfile, uint8_t *pd_out, size_t expected_nchars, struct _GHashTable *decoders_hash ); MyChanged version: size_t convert_payload_to_samples(unsigned int payload_type, QTemporaryFile *tempfile, uint8_t *pd_out, size_t expected_nchars, struct _GHashTable *decoders_hash , size_t fecflag = 0); 2、Add some codes to support OPus fec、play and save.In my opinion these codes don't affect other functions.(In the files: rtp_audio_stream.cpp rtp_audio_stream.cpp ) I don't know whether the change is useful and meets specifications. The other question: In the RTP protocol, Opus don't have a fixed payload type. Now I write the payload type into macro. DoesithaveagoodwaytoletuserchoosetheOpuspayloadtype? Althoughtried ,Ifailed~~ I don'tknowhowtorealizeit. It is my first time to participate in a open source project. And I want to make a contribution. I don't know whether it is a good way to plugin Opus into WireShark or not. If not , is there a better way? I want to know and try it! Best regards, Ryan Lee
