Description
OS: Slackware64-current
MPlayer-1.3.0-x86_64-1
ffmpeg-3.3-x86_64-1
Summary of the bug: When playing files through a playlist MPlayer will sometimes crash after a video ends and when trying to start the next one in the playlist. This only started after compiling MPlayer with ffempg-3.3, it did not occur with ffmpeg 3.2.
How to reproduce:
Start a mplayer playlist, wait a little bit for it to play and then skip to the next video. Repeat up to a few times if it doesn't occur the first time.

Can you confirm the crash happens only without FFmpeg commit 3a6ded7cfc ?
The mentioned commit fixed a vdpau crash bug that I could trigger with some files, especially when pressing enter early after starting up mplayer.

Yes. It seems that FFmpeg commit 3a6ded7cfc solved this. With FFmpeg-3.4 where this is applied the crashes stopped. I also tried reverting that change with an internal version of FFmpeg-3.4 and the crashes quickly resumed. I would consider this fixed until someone can reproduce it again. Thanks again for the help in irc!

Thank you for reporting this issue and actively helping to resolve it even after the problems didn't occur anymore with your mplayer installation.
I just switched resolution to invalid as the problem was fixed outside of MPlayer in FFmpeg commit 3a6ded7cfc .
I have discovered some more details.
This will only occur with hwdec, as I am a nouveau user this requires the firmware extracted from the nvidia blob and I configured mplayer following the nouveau documentation:
vo=vdpau
[vo.vdpau]
vc=ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau,ffh264vdpau,ffodivxvdpau,
https://nouveau.freedesktop.org/wiki/VideoAcceleration/
If I comment the 'vc' line it no longer occurs. However the whole reason I use MPlayer is the hwdec support.
Additionally it doesn't seem to crash every time and I have tried running it in valgrind where it does not crash.
