Hello,
Thank you very much for your inputs.
When I don't use --disable-yasm option, I got tons of errors just because the
yasm version that we are using in openembedded is quite old and ffmpeg requires
a newer version of yasm. Updating yasm is fairly easy but then I got multiple
of tons of different errors due to compatibility issues between different
packages that are used in openembedded.
I guess there is no option except updating the whole openembedded which is way
beyond my knowledge.
Thanks a lot.
Regards,
