Description Jean-Yves Avenard [:jya] 2023-11-17 02:11:11 PST 
seen with bug 264931 ; when playing a broken webm, the error event isn't fired.

media/media-webm-opus-error.html is a perma-failure
Comment 1 Philippe Normand 2023-11-20 02:51:23 PST 
LayoutTests/media/content/opus_variable_witherror.webm plays fine in VLC and in GStreamer-based players.

What's supposed to happen when that file is loaded, exactly?
Comment 2 Jean-Yves Avenard [:jya] 2024-01-22 03:58:44 PST 
The track Id is 2^64 which is an illegal value.

This is handled properly by libwebm parser and it will return an error when parsing the metadata
Comment 3 Philippe Normand 2024-01-22 04:33:23 PST 
Ah, that might explain why it plays in GStreamer then, since AFAIK we don't validate track metadata there...
Comment 4 Philippe Normand 2024-01-22 10:46:59 PST 
There's this...
