Yes, we start a new video whenever the dimension changes. On an uncongested network, there should be a 10 second low-resolution segment, and then the resolution stabilises at the highest value. This was already the case in 0.3, but we were losing the low-resolution segment (the recording was only started at the second keyframe). The alternative would be to use a single webm file even though the resolution changes. This happens to work fine with mpv and vlc, but is a violation of the Matro=A8ka format. > * In Firefox (78.13), Simulcast refuses to be activated (on) and turns to= off. > (auto is OK) Firefox uses a non-standard protocol for simulcast. I've tried to implement it (Sean has recently added support to Pion), but it doesn't work with the version of Firefox currently in Debian, and I don't see a good way to distinguish the good versions from the bad ones. > * In the op/presenter video window the bitrate is now only numbers (witho= ut its > unit of measurement) Noted, thanks. > Playing, as op/presenter, video streaming (Play local file) from a mp4 (= using > MacOS 10.11.6) >=20 > * Chromium (95.0.4635.0): not working (black screen) Known issue, https://bugs.chromium.org/p/chromium/issues/detail?id=3D1156408 > * Chrome (93.0.4577.63) OK (the op/presenter gets the sound) Strange.
