Hello and thanks for maintaining Firefox in Debian!

I noticed that some YouTube videos[^NOTE] fail to be played on firefox-esr,
but are played with no issues on chromium (hence the videos themselves
do not seem to be somehow 'broken'...).

[^NOTE]: such as <https://www.youtube.com/watch?v=rm6uCcHQM9w>

The playback never starts and stays in an eternal buffering state. Shortly,
the message

  If playback doesn't begin shortly, try restarting
                  your device.

appears.  Nothing else happens.

I have already tried in safe mode:

  $ firefox-esr -safe-mode

but nothing changed.

A good number of Youtube videos are played flawlessly, but some fail,
as described above.


I have already taken a look at other YouTube-related bug reports,
but my problem seems to be a distint one...

What could I do in order to debug this issue?
Please let me know.

Thanks for your time!

Hi,

I also want to say thanks for maintaining Firefox in Debian!

I noticed in the past couple of days that a video I had previously played extensively had stopped working.

https://www.youtube.com/watch?v=Ga3maNZ0x0w   <- very popular 'live' video

The 'debug info' from Youtube contains this fragment:

  "debug_error": {
    "errorCode": "fmt.unplayable",
    "errorDetail": "itag.242;seg.2256990;time.14387.1-14392.1;off.0;len.115183;end.1;merr.4;msg.0x80004005_ IsInitSegmentPresent_ Invalid webm content",
    "message": "An error has occurred. Please try again later.",
    "messageKey": "YTP_ERROR_GENERIC_WITHOUT_LINK"
  }

'Stats for nerds' mentions 'Codecs: VP9 (244) / mp4a 40.2 (140)'


Regards,

Scott.
