Description Olivier Crête 2010-01-06 18:34:08 UTC

The user initiate a call with the local codec "96 = H264, 97 = H263-1998".
The remote side (google video) replies with "97 = H264", which is set as remote codecs to tp-fs. And tp-fs replies with SupportedCodecs (97 = H264)

Afterwards, the CodecsUpdated call should the new list, not the original one. So 97 will be H264.

But currently, it seems that Gabble caches the origin one and tries apply updates to it so I get a spurious "Error calling Media.StreamHandler::CodecsUpdated: tried to change codec 97's name from H263-1998 to H264"..

Comment 1 Olivier Crête 2010-01-06 18:35:37 UTC

That said, I should mention for the record that the Google Video variant doesn't have the concept of updated codecs. So it is a concern for future interoperability.

I'm still seeing this issue using Ubuntu 10.04:

$ dpkg -l | grep telepathy

When I use empathy to connect to google video:
Error calling Media.StreamHandler::CodecsUpdated: tried to change codec 97's name from JPEG2000 to H264

This results in a one-way video chat where I can see the remote video on empathy from Google Video, but not the remote video on Google Video from empathy
