#5274 open enhancement

vc1 with main profile fails to decode

Reported by: ami_stuff Owned by:
Priority: wish Component: avcodec
Version: git-master Keywords: vc1
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

file encoded with advanced profile decodes just fine

I don't know if this is a bug in ffmpeg or in encoding software.

Does the encoder also allow to encode into a container?

I will test it later - would need to turn on my laptop.

Replying to cehoyos:

Does the encoder also allow to encode into a container?

It can output either to raw vc1 or wmv (in this case there is no main profile, only advanced and simple profile - simple profile is for some reason unselectable for encoding, advanced decodes with ffmpeg just fine)

Could you upload more samples?
Which encoder you used?
