This keeps cropping when remuxing from F4V to FLV.

Handle it in the same way as VP6F, except for the codec tag.
Signed-off-by: Martin Storsjö <martin@martin.st>

The plain VP6 format is vertically flipped compared to VP6F/VP6A.
Support for the plain VP6 format was added in 09d8c0ae (which
also introduced support for muxing VP6F properly in general).
Signed-off-by: Martin Storsjö <martin@martin.st>

In these cases, there is no extradata but only the properly set
width/height values by the demuxer.

This makes sure VP6 in F4V files is cropped properly.

This is similar to what is done for H264 for letting the container
width/height override what's in the bitstream, since 30f51509.

This ensures that all the non zero fields get setup correctly.
Alternatively their initialization could be duplicated.
