Comment (by msiders):
Hi,
Peharps the problem is related to the fact that the "hwdownload" filter is
using the size from the output:
https://github.com/FFmpeg/FFmpeg/blob/90ac0e5f29ba4730cd92d3268938b3730823e52b/libavfilter/vf_hwdownload.c#L158
{{{
output->width = outlink->w;
output->height = outlink->h;
}}}
As the "hwupload" gets it from the input:
https://github.com/FFmpeg/FFmpeg/blob/90ac0e5f29ba4730cd92d3268938b3730823e52b/libavfilter/vf_hwupload.c#L172
{{{
output->width = input->width;
output->height = input->height;
}}}
