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.
 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.
