[FFmpeg-devel] [PATCH]Don't claim 16bit support for the noise filter

[Carl Eugen Hoyos]

Hi!

The noise filter claims to support 16bit formats but the output looks broken:
$ ffmpeg -f lavfi -i testsrc=s=3840x2160 -vf 
format=yuv444p16le,noise=c0s=10:allf=t -vcodec mpeg4 -qscale 2 -t 1 out.mov

Attached patch removes the 16bit support, fixes ticket #4017, ticket #4029 for 
16bit support already exists.
