Comment (by ahthovaikied):
Replying to [comment:43 ubitux]:
> Assuming the change was introduced in 194be1f4, this is indeed a change
from Libav which was merged in ac293b6. Libav 10.3 does not include this
change AFAICT; you probably want to compare with Libav git/master, or
simply any hash ≥ 194be1f4.
Thanks.
The problem is libav master does not build with {{{--disable-decoders
--disable-hwaccels}}}, I get link errors like:
{{{
libavcodec/libavcodec.a(vc1dsp.o): dans la fonction « ff_vc1dsp_init »:
vc1dsp.c:(.text.unlikely+0x22d): référence indéfinie vers «
ff_vc1dsp_init_x86 »
collect2: error: ld returned 1 exit status
make: *** [avprobe] Erreur 1
}}}
Same for v11_alpha1 or v11_beta1 (who have the commit).
I did a test at 194be1f4 (which builds successfully), and the MD5 are the
same as for v9.5 or v10.3, with or without {{{--disable-decoders
--disable-hwaccels}}}, which seems more logical to me than FFmpeg's
current behavior.
