[SOLVED] h264 problem with GStreamer since ffmpeg5

Hi,

GStreamer seems unable to handle h264 now that ffmpeg5 has been pushed, was working fine with ffmpeg4. The system is up to date. Some information:

$ pacman -Q | grep -E "(gst|gstreamer)"

Re: [SOLVED] h264 problem with GStreamer since ffmpeg5

Fixed : had to

rm -r ~/.cache/gstreamer-1.0

which is not explicitely said when updating ...
