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. ...
