changing timecode with text, doesn't trigger the segfault.

Hi , sorry for the delay.
the external x264 is not needed and I can reproduce with the other flags.
Here is a command which uses both and segfault.

Replying to lorenzo.angeli:
Hi, where can I get the ffmpeg_g to provide gdb informations ?
You will have to compile yourself with --enable-libfreetype (or report the issue to where you downloaded the binary from, remember that the FFmpeg project only provides source code, no binaries).
comment:7 by , 9 years ago
Oh sorry, here is where I get it from:
http://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz
I'll try to understand how to report it there.
Cheers.
L.
Note:
See TracTickets
for help on using tickets.
Is an external library like x264 necessary to reproduce the issue or is it also reproducible with
-vcodec mpeg4 -qscale 2?Is a specific input necessary or is the issue also reproducible with
-f lavfi -i testsrc?
