Package: libpurple0 Version: 2.13.0-2+b1 Hi,
This is observed with the pidgin & libpurple included on plain Debian 10. Whenever I try to establish an audio-video call, I get the following error boxes: Call with sip:john....@hisdomain.lu failed Conference error Media error Conference error Call with sip:john....@ourdomain.lu failed Error with your webcam Media error Error with your webcam A small investigation showed that this was due to the gstreamer pipeline not being able to negotiate a common format. Originally, this pipeline is v4l2src --> videoscale --> prpl_video_caps --> tee --> ... prpl_video_caps is a filter on format (video/x-raw), size and framerate. The odd thing is that there is nothing in the pipeline before this filter to adapt format and framerate. Unfortunately, manipulating the pipeline to also include videoconvert and videorate before the filter doesn't fix this. However, changing the prpl_video_caps to not filter on format, but only on size and framerate and then inserting an extra filter with just the format after videoconvert does seem to address the issue: v4l2src --> videoconvert --> formatfilter --> videoscale --> prpl_video_caps --> tee --> ... Where formatfilter filters on video/x-raw, and prpl_video_caps now solely filters on width=[250,352], height=[200,288], framerate=[1/1,20/1] It is weird, as the simpler configuration (one filter to filter on everything) does work in gst-launch: gst-launch-1.0 v4l2src ! videoconvert ! videoscale ! "video/x-raw,width=[250,352],height=[200,288],framerate=[1/1,20/1]" ! xvimagesink Attached is a log with the error, and also a LD_PRELOADable object to do the GST pipeline manipulation described above which works around the issue. N.B. I initially tried to report this to the TRAC bug reporting system mentioned at https://developer.pidgin.im/wiki/TipsForBugReports but unfortunately, it didn't let me register an account for doing so: Error: Not Found No handler matched request to /register Thanks, Alain _______________________________________________ Support@pidgin.im mailing list Want to unsubscribe?
