[Libav-user] Converting from one pixel format to another using the scale filter

[Benjamin Pernot]

Hi all,

I would like to use the scale filter (based on swscale) to convert from one
pixel format to another, which means that I would like to be able to
specify to this filter the "dst_format" parameter (as well as "src_format"
parameter).
Unfortunately from what I can see in the source code (vf_scale.c), the
"dst_format" parameter can not be configured but it is automatically set as
such :

enum AVPixelFormat outfmt = outlink->format;
...
av_opt_set_int(*s, "dst_format", outfmt, 0);


How can I override the "dst_format" parameter?

Thanks in advance,

Ben
