    Remove lowres video decoding

    This feature is complex, of questionable utility, and slows down
    normal decoding.

    Signed-off-by: Mans Rullgard <mans at mansr.com>


low-res video decoding is used in mythtv in order to flag a video for
commercial.

Removing this mode breaks mythtv's comm flagging.
Doing comm flagging without low res reduced speed by a factor of two.

So I would like to plead to reverse that change.
There was no need to remove it.

Thank you
