Bug 197861 – [GStreamer] YouTube videos without WebM source available break youtube.com when gstreamer-libav is unavailable

• Component: Media
• Status: RESOLVED FIXED

[Michael Catanzaro]

YouTube videos without WebM source available break youtube.com when gstreamer-libav is unavailable. Test on, for example: https://www.youtube.com/watch?v=bzOxzJNdpH0

I think this is a recent WebKit regression. Until recently, youtube.com loaded but displayed an error message over the video. Now the error message appears for about half a second before it disappears and the page breaks.

That does have WebM fallback for me.

These bug reports are not very useful without some sort of debug log, a core, or failing being able to do the above, a screencast / screenshot of what you're actually seeing. "The page breaks" is really ambiguous.

screenshot of broken page

I'm surprised you're not able to reproduce the same breakage.

I don't know what sort of debug log you'd want. Phil often asks for a GStreamer debug log using environment variables I can never remember. You're welcome to ask for whatever you want.

> a core

There's no crash.

I'm testing with 2.24.1 on Fedora 30 and it breaks as shown. In my flatpak environment, everything is fine. I had assumed gstreamer-libav was the difference; it seemed likely.

I get the webm fallback you said doesn't exist for you, so it seems were having quite different experiences!

Let see if GStreamer fails in any way,

GST_DEBUG_DUMP_DOT_DIR=. WEBKIT_DEBUG=Media,Events GST_DEBUG='*:2,webkit*:MEMDUMP' ... your webkit command line ... 2>&1 | tee run.log

After that, please tar up all the *.dot and the run.log file so we can check what might be going wrong there.

Perhaps, I'm running off both trunk webkit and gstreamer. I disabled loading of gstreamer-libav and got the webm fallback on that video, so it's not reproducible for me here.

Ignore the three warnings at the top (Epiphany bugs):

This is 2.24.1 here, did you try 2.24.1? I wonder, could it be fixed by r244111 (not present in 2.24.1)?

[Philippe Normand]

Looks like yet another issue in your Runtime:

[📦 org.gnome.Epiphany.Devel ~]$ gst-inspect-1.0 |grep vp8
libav:  avdec_vp8: libav On2 VP8 decoder
rtp:  rtpvp8depay: RTP VP8 depayloader
rtp:  rtpvp8pay: RTP VP8 payloader


The vpx gst plugin is missing, so if you remove gst-libav, you also lose vp8 decoding support...

Where is that supposed to come from?

[Philippe Normand]

gst-plugins-good and the external libvpx dependency

[Michael Catanzaro]

Looks like it's an automagic dependency:

https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/blob/af0198853415cd64f5f6b8bba3e0affd68431752/configure.ac#L1017

so it gets disabled because libvpi is not pulled in here:

https://gitlab.com/freedesktop-sdk/freedesktop-sdk/blob/94b481700159c34fd85c5625a08729d7414ac100/elements/components/gstreamer-plugins-good.bst

I'll ask freedesktop-sdk to enable this, but this is just going to keep happening in other distros that don't use the meson build (where we can use -Dauto_features=enabled to prevent such problems).

Well looks like you have found a different bug.

The bug I reported here is fixed in 2.24.2, probably by r244111. Problem is definitely gone. I was using Fedora 30, not flatpak.
