Comment (by ahthovaikied):
Replying to [comment:27 Cigaes]:
> Good. Now you must try and spot differences in the
{{{extradata_hash=MD5:...}}} values. If not, you will need to do the same
with {{{-show_packets}}}. If you do not find differences, that means that
the output part is producing different output, not the input part.
Without {{{--disable-vaapi --disable-vdpau}}}:
{{{
$ ffprobe -show_packets -show_data_hash md5 cut.mkv 2>&1 | grep -F
'data_hash=MD5:' > /tmp/data_hashes1.txt
}}}
With {{{--disable-vaapi --disable-vdpau}}}:
{{{
$ ffprobe -show_packets -show_data_hash md5 cut.mkv 2>&1 | grep -F
'data_hash=MD5:' > /tmp/data_hashes2.txt
}}}
No difference:
{{{
$ diff /tmp/data_hashes{1,2}.txt
$
}}}
