Bug#958865: mplayer: theora playback broken: vf_get_image: Assertion `h == -1 || h >= vf->h' failed.

Package: mplayer
Version: 2:1.3.0-8+b4
Severity: important

Hi,

I struck this issue trying to play a Ogg/Theora video originally on
Ubuntu 18.04 LTS and later reproduced the exact same conditions on
Debian 10.

I tried installing the "unstable" release of `mplayer`, however its
dependencies on `libc6` prevented me from doing so safely. I am not
sure when the Debian 11 release is expected, so I am sticking to version
10 for now.

The above bug is pretty easy to reproduce anyway, and can be reproduced
on both Debian and Ubuntu, which says to me its something common to both.

MPlayer is no longer developed and largely replaced by mpv.

I can suggest to try use mpv instead. If you dislike the minimal builtin
user interface, then try one of the frontends gnome-mpv or smplayer.

I can play the above video just fine with mpv, but your problem might be
related to other parts of your system (graphics driver, X11 or Wayland
setup, etc.).



Kind regards,

- Jonas

Right, wasn't aware of mplayer's demise… my use case was to play a
full-screen video without sound as the screen saver… so I have the
following:

stuartl@vk4msl-nb:~$ cat .screensavers/playrandom.sh
#!/bin/bash

if [ -n "$1" ]; then
XSCREENSAVER_WINDOW=$1
fi

exec /usr/bin/mplayer -nosound -fs -really-quiet \
${XSCREENSAVER_WINDOW+-wid} \
$XSCREENSAVER_WINDOW \
-nolirc -nostop-xscreensaver \
-shuffle \
/home/stuartl/.screensavers/*.{mkv,mpeg,mp4} \
/home/stuartl/.screensavers/*/*.{mkv,mpeg,mp4}
stuartl@vk4msl-nb:~$ grep -C 3 playrandom.sh .xscreensaver
textURL: http://planet.debian.org/rss20.xml

programs:
\
"Random video"
/home/stuartl/.screensavers/playrandom.sh \
$XSCREENSAVER_WINDOW
\n\
- maze -root
\n\
- GL: superquadrics -root
\n\

This works well, with MPEG4 files, it crashes and burns with Ogg/Theora.

I'll have to see if mpv can pull off the same trick as mplayer.

Turns out it can:

stuartl@vk4msl-nb:~$ cat .screensavers/playrandom.sh
#!/bin/bash

if [ -n "$1" ]; then
XSCREENSAVER_WINDOW=$1
fi

exec /usr/bin/mpv --no-audio --fs --really-quiet \
${XSCREENSAVER_WINDOW+--wid} \
$XSCREENSAVER_WINDOW \
--no-stop-screensaver \
--shuffle \
/home/stuartl/.screensavers/*.ogv \
/home/stuartl/.screensavers/*/*.ogv

and my Ogg/Theora videos play with it… so okay, time to `apt-get purge
mplayer`.

It's fair enough to point people to alternatives,
but I don't think it's ok or fair to blame upstream
for issues that have been long fixed (this one in
April last year).

Is your complaint that in 2020 I failed to predict that upstream would
issue a bugfix 2 years later?!?

This was not meant as a personal attack on anyone,
I do not know all the details of this issue.
But from what I know, while it was reported to Ubuntu
and Debian, this issue was never reported by anyone
to MPlayer.
In addition, it only occurred due to specific compile
options used by these distros (--enable-debug).
To my knowledge the issue was fixed very shortly after someone from MPlayer (me) became aware of it.
Maybe it's of little practical relevance for Debian users, but for upstream developers it's not so much fun for the project to be declared dead because the communication between distro and upstream broke down.
And bug fixes is one of the few things that MPlayer still does get even though you are right that there is very minimal development.

Hope that explains my point and sounds reasonable.

Thanks,
Reimar
