Local camera not working locally

I’m running Jitsi 2.11.5611 installed from your repository on Debian stretch. Options → Video lists and enables the local camera, but the picture remains black and I see the following message:

SEVERE: [96] org.jitsi.impl.neomedia.codec.video.HFlip.log() avfilter_graph_config: -22,
             format AVFRAME, 640x480, class org.jitsi.impl.neomedia.codec.video.AVFrame,
             pixFmt 1, deviceSystemPixFmt 0x56595559

The same happens when enabling “Show local video” in a video call. However, the remote side does see my video stream.

This is probably due to some change between 2.11.5602 and 2.11.5604: the former version works for me, the latter doesn’t.

Not sure this is an actual bug or just an incompatibility with some Debian stretch component. The issue described in https://community.jitsi.org/t/camera-not-working-with-jitsi-desktop/15038/ sounds similar, but I’m not sure it’s the same thing.

Exactly the same error here on Ubuntu 19.10.

Where did you find of how did you manage to build a jitsi desktop for Ubuntu 19.10 ? The debs in the jitsi repos have some dependency problems (libavformat57 needed but Ubuntu ships with libavformat58 for instance).

How did you manage to build Jitsi Desktop for Ubuntu 19.10 [or Ubuntu 20.04 LTS]?

(a) If you do not need H.264 video codec, you override those dependencies. (b) If you need H.264, you have to compile yourself …
