Package: mplayer
Version: 2:1.3.0-3
Severity: normal
Dear Maintainer,
mplayer crashes when taking a screenshot, this is how to reproduce the
issue:
$ mplayer -vf screenshot file.avi
and then press 's' on the keyboard.
I am attaching a full backtrace of the crash, but from the mplayer log
you can already see some anomalies:
...
libavformat version 57.41.100 (external)
Mismatching header version 57.25.100
...
[png @ 0x7ffff29c1040]The encoder timebase is not set.
Could not open libavcodec PNG encoder
FATAL: Cannot initialize video driver.
...
Thanks,
Antonio
