#1923: vble: problem with version check

for certain resolutions vble codec writes something else than $01 as an
version to the output file
(or at least $01 value is at the different place)
the binary codec seems to not care about version at all while decoding the
file, so maybe a fix would be to remove version check from the ffmpeg's
code
