[MPlayer-dev-eng] [PATCH] HuffYUV native support

[Arpi]

Hi,

> files (RGBA not supported yet).
> 
> Output format is YUY2 or BGR32,BGR24, and is selected in init function 
> because frame format is not known at demuxer. This portion does not

your request is only the 'preferred outfmt'. so, when no common supported
outfmt, then it will be used as input of conversion (not yet implemented).

the list of supported outfmts is still in codecs.conf, but you can implement
the QUERY_FORMAT control() call so these will be queried, and in case of
FALSE reply they will be removed from codecs.conf list by vd.c.

see the vd_raw.c for example.

the QUERY_FORMAT control call will be called from mpcodecs_config_vo().

yes. also implement that control() case.
only automatic conversion missing from libmpcodecs.

ok
