hello, seems that webkitgtk has some troubles with some youtube videos, as they are not playing while some others are gathered this on the terminal, from epiphany in fedora 35, maybe it will help? (WebKitWebProcess:2): GLib-GObject-WARNING **: 20:34:32.280: g_object_set_is_valid_property: object class 'avdec_av1' has no property named 'max-threads'
Thanks for the bug-report. Can you gather some logs please? The procedure is explained there: https://github.com/Igalia/meta-webkit/wiki/Providing-useful-GStreamer-Zero-copy-issue-reports#in-webkit

Please attach logs here... not in the other bug.

(In reply to 247 from comment #4) > my bad i found later the right command, anyway i would love to help you but > unfortunately the folder in tmp that should contain logs is empty... That's quite odd, I doubt Fedora disables GStreamer debug logging. Not sure I can help much without this...
GST_DEBUG="3,webkit*:6" GST_DEBUG_DUMP_DOT_DIR=/tmp epiphany "https://www.youtube.com/watch?v=XIAor5VAjuE" shows nothing either?
if the folder is /tmp/epiphany-luca247-e8l4pX then yes it's empty...
I mean in the terminal output...
it's actually full of c:2068:gst_ffmpegviddec_handle_frame:<avdec_av1-0> Failed to send data for decoding 0:00:22.626063912 2 0x7fc17c00b760 ERROR libav :0:: video_get_buffer: image parameters invalid 0:00:22.626071981 2 0x7fc17c00b760 ERROR libav :0:: get_buffer() failed 0:00:22.626077629 2 0x7fc17c00b760 ERROR libav :0:: thread_get_buffer() failed 0:00:22.626083319 2 0x7fc17c00b760 ERROR libav :0:: Failed to allocate space for current frame. 0:00:22.626088690 2 0x7fc17c00b760 ERROR libav :0:: Get current frame error 0:00:22.626095629 2 0x7fc17c00b760 WARN libav gstavviddec.c:2068:gst_ffmpegviddec_handle_frame:<avdec_av1-0> Failed to send data for decoding
Try this? export GST_PLUGIN_FEATURE_RANK=avdec_av1:NONE Then run epiphany again
this solves the problem, thank you...
What's the ffmpeg version you have? I think this should be reported in their bug tracker if the issue is still happening.
The ffmpeg av1 decoder is going to be disabled in GStreamer 1.20, see https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3610 Closing.
