epiphany: cant play videos

ghost commented 1 year ago

Describe the bug

I tried to test it because I want see if hw media acceleration actually works now, but I've found out that it doesn't reproduce a single video at all!

Steps To Reproduce

Steps to reproduce the behavior:

Install epiphany
Open it (called Web)
Try to watch a video on youtube

Expected behavior

Video plays.

Additional context

I set the environment variable to have full gstreamer support on all apps that support it, and thought that could be interfering, but even disabling it, video still can't be played.

What environment variable did you set?

Epiphany should already have GStreamer set up by default:

I disabled that, rebooted and tried to watch a video and it still didn't play. Re-enabled afterwards. :/

Having issues with my VPN setup right now and cannot properly test :upside_down_face:. Some of the things I can think of:

Try the Flathub epiphany
Check the environment variables env | grep GST
Get some logs using GST_DEBUG="3,webkit*:6" GST_DEBUG_FILE="$HOME/gst.log" GST_DEBUG_NO_COLOR=1 WEBKIT_FORCE_SANDBOX=0 LANG=en_US.UTF-8 epiphany "https://insert-your-youtube-link-here.com", and look for errors in $HOME/gst.log
In a nix-shell -p gst_all_1.gst-libav -p gst_all_1.gst-plugins-bad -p gst_all_1.gst-plugins-base -p gst_all_1.gstreamer -p gst_all_1.gst-plugins-good -p gst_all_1.gst-plugins-ugly shell try to play the test videos with gst-play-1.0 --videosink glimagesink /path/to/video.

Get some logs

gst.log

in a shell try to play the test videos

I tried the highest resolutions and they all work fine.

I have the same problem, but videos work if setting WEBKIT_DISABLE_COMPOSITING_MODE=1 before launching epiphany, I think this issue has to do with nvidia drivers (I use the proprietary ones on a laptop) and webkitgtk. This issue may be related: #32580

NixOS / nixpkgs
