media: vicodec: Handle the case that the reference buffer is NULL

2019-03-25T17:50:44+00:00

In the stateless decoder the reference buffer is null if the frame is an I-frame (flagged with FWHT_FL_I_FRAME). Make sure not to dereference it in that case. Signed-off-by: Dafna Hirschfeld Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vicodec: rename v4l2_fwht_default_fmt to v4l2_fwht_find_nth_fmt

2019-03-25T17:50:00+00:00

Rename 'v4l2_fwht_default_fmt' to 'v4l2_fwht_find_nth_fmt' and add a function 'v4l2_fwht_validate_fmt' to check if a format info matches the parameters. This function will also be used to validate the stateless params when adding support for stateless codecs.
