#1075 Crash - static ffmpeg using ffmpeg and .mp4, matroska formats

[pottendo]

hi,

building with static ffmpeg on Ubuntu 18.10 leads to crash when trying to use ffmpeg with formats .mp4 or .matroska - others (.avi, etc.) seem to work.

here's the bt:

I've tested this on Ubuntu 18.10 in a VBox VM, recording of avi and mp4 work both using static and external ffmpeg. No segfaults, and playing the videos on my host with VLC works. (Trying to play them inside my VM causes immediate crashes, seems to be VBox issue).

My test cases were ~10 seconds of the blinking cursor on the x64sc boot screen.

I have the same problem. Fresh build with

./configure --enable-native-gtk3ui --enable-static-ffmpeg --prefix $HOME/vice-3.3

and the same h264 slicetype_slice_cost segfault.

Does this still happen?

No activity in years and statically linking against ffmpeg was removed from VICE years ago. Closing.
