Once again an upgrade to Bookworm on a Pi5 has killed video playback in
both Firefox and Chromium browsers. The video starts to load, thumbnails
keep coming but the playback doesn't start and there's no sound.

I've tested it on the New York Times, YouTube, Netflix and some homemade
videos that used to work. Now nothing plays, failing in the same way.

If anybody's seen this or knows a fix, please post.

Thanks for reading,

What do you mean "once again"? Have you had this problem before? How did
you solve it then?

... and why upgrade to Bookworm? Trixie (Debian 13) is the current version.

It's been cropping up routinely, a day or so after updating the system.

Simply continuing to update as updates were offered. Last time this
occurred the issue was resolved in a couple of weeks, IIRC.

Bookworm is the established install on the host in question.

If there was reason to think upgrading to Trixie would help I'd try it,
but so far nobody has suggested that's the case. Bullseye seemed to work
pretty well, Bookworm somewhat less so. That trend isn't encouraging....

Far as I've seen, the _only_ problem has been with watching videos.
Otherwise the system is well-behaved.

When you start Firefox from a terminal does it complain about any
missing libraries? Do video files play in other programs using
libavcodec (mplayer, ffplay)?

No, I don't think there's any particular reason to prefer Trixie over
Bookworm if Bookworm works for you. Support for Debian "oldstable" is
usually pretty good from Debian (though I think the Raspberry Pi people
tend to concentrate on "stable", which would be Trixie at present).

Some third-party software works well with the RaspiOS that is current
when it is released, and may only slowly (if ever) be updated for newer releases -- I'm thinking of support for some of Pimoroni's devices.

OTOH things like the Pi camera software is intended for "stable", and
newer features/cameras may not work at all with older distros.

Far as I've seen, the _only_ problem has been with watching videos. Otherwise the system is well-behaved.

I'm not aware of any major differences in video support between distros.
There IS a difference in hardware video support between Pi4 and Pi5 (I
forget the details ... Pi4 has support for H.264 (and H.265?) but Pi5 -
being much faster - expects you to do it in software? Something like
that.). Of course, with a Pi5 you need a release that supports the Pi5,
and I think Bookworm is the minimum.

If I point firefox at www.youtube.com the controlling terminal reports a series of

Starting chromium causes the controlling terminal to emit

I've not paid any attention to controlling terminals on RasPiOS recently,
so I don't really know what to expect. It certainly looks like both Firefox
and Chromium have things to complain about.

Thanks for writing!
