Description

Trying to use mencoder as decoder to feed x265 (16bit build) and converting the 8bit input to 10bit output.

I use:

mencoder -lavdopts threads=8 -of rawvideo -o - -ovc raw -demuxer lavf -noskip -vf scale,format=i420,scale,format=420p10le -forcedsubsonly -nosub -nosound "test.mkv"

for the decoder call, problem is it aborts with:

why have two scales and two formats?

can you use ffmpeg instead ? mencoder is barely maintained for the last 5 years.

Keywords: ve_raw added; stdout high bit depth removed
Reproduced by developer: set
Status: newopen

the problem is mplayer/libmpcodecs/ve_raw.c (the file that lists what raw formats can be used for mencoder) has not been updated with the 10bit codecs.

patch welcome.
