MediaPlayer crashes with MPEG4/ffmpeg video

[grexe]

playing and seeking through the video "Madness Concert Beloise (2017)" (Arte in Concert series, video is sadly not available online anymore, can provide on request, was from TV channel arte.tv)

At roughly 52:50 in, MediaPlayer crashed (see attached report). Couldn't yet reproduce.

MediaPlayer file info says:

Container: QuickTime / MOV (FFmpeg)
Video: H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
             1280x720, 25.000 fps
DisplayMode: DrawBitmap
Audio: AAC, 32bit stereo, 48kHz, 122.50KiB/s

ah, just discovered that this may be because of an incompletely downloaded video - Otter Browser crashed and I lost the last part of the video. Trying to seek to that last part failed, MediaPlayer seemed to hang, but quitting worked normally without crashing.

so it's more about making seeking through damaged media files more robust, which is maybe a translator issue after all, or an issue in media_kit?
