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,
