I am trying to use galene-stream v0.6 with Python 3.11.5 and Galène 0.7.2. I run an up-to-date Arch Linux, with gstreamer 1.22.5.

I am running this command:

galene-stream -i rtmp://localhost:1935/live/test -o wss://galene.myserver.eu/ws -g test -u PC --debug

And publishing to the RTMP server using OBS.

When I try to run the server, I am getting two gstreamer errors once the input stream loaded and before the WebRTC session negociated (between "Waiting for incoming stream" and "Setting local description"):

0:00:05.497522029 27907 0x7f1214001450 WARN         audio-resampler audio-resampler.c:274:convert_taps_gint16_c: can't find exact taps

The local and remote SDP can be found below. Please note that the remote SDP does not have any video source, and has a line m=video 0 UDP/TLS/RTP/SAVPF 0 that indicates that video is deactivated.

When the remote SDP is sent, I got a new error:

0:00:05.706262782 27907 0x55d768850340 WARN               webrtcbin gstwebrtcbin.c:6671:_set_description_task:<send> returning error: media 0 is missing or contains an empty 'mid' attribute

Which is consistent to the previous notice.

Here is the full pipeline:

GST trace log can be downloaded there: trace.log

And then the (redacted) log output:

OBS can't be the cause of that, I tried to replace the pipeline with:

webrtcbin name=send bundle-policy=max-bundle
videotestsrc ! videoconvert ! vp8enc deadline=1 target-bitrate=1048576 ! rtpvp8pay pt=97 ! send.
audiotestsrc ! audioconvert ! audioresample ! opusenc ! rtpopuspay pt=96 ! send.

And it does not change anything, and I don't see nor hear anything on Galène.

If I try to deactivate the video stream from the pipeline, then the two first error lines are still there, but the WebRTC negociation is working and sound is transmitted. But, an error line is spamming the output console:

rtpsession gstrtpsession.c:2435:gst_rtp_session_chain_send_rtp_common:<rtpsession0> Can't determine running time for this packet without knowing configured latency

And one strange thing: if I am using VP9 instead of VP8 (replacing vp8enc by vp9enc and rtpvp8pay by rtpvp9pay), then the video stream is working (but with a very strong CPU usage), but the error lines are still there.

I also tested the same versions under Ubuntu.

Is there something broken with the newest versions of Gstreamer? Or did I make something wrong?

I believe that you are using Galène on master branch which disables VP8: jech/galene@69445d6#diff-2b7814d3fca2e99e56c51b6ff2aa313ea6e9da6424804240aa8ad891fdfe0900L173

Can you try to add ["vp8", "opus"] to your Galène group codecs?
