Comment (by lorenzo.angeli):
Hi, where can I get the ffmpeg_g to provide gdb informations ?
system : {{{Linux hdd-XPS-15-9530 3.16.0-45-generic #60~14.04.1-Ubuntu SMP
Fri Jul 24 21:16:23 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux}}}
here the bare minimum I can provide in order to reproduce:
{{{
./ffmpeg -v 9 -loglevel 99 -y -f lavfi -i testsrc -vcodec mpeg4 -qscale 2
-filter_complex "[0:v] drawtext=timecode=\'00:00:00:00\':r=25.0[v]" -map
[v] /home/efesto/Desktop/foobar.mov
}}}
here is the output
