[FFmpeg-devel] Filter with multiple inputs, specific format on second and third input?

2016-03-11 Thread F.Sluiter
I am writing a filter that takes a video file and remaps pixels based on second and third input. second and third input are pgm files, which should give me a list of integers (gray16) that I can use in the filter. However ffmpeg by default converts my pgm files to YUV. Is there a way to prevent tha

Could you actually be more specific, what would be needed for 16bit support? I was naively thinking to just a binary copy from source pixel to target for starters. 2016-02-25 22:40 GMT+01:00 F.Sluiter : > It would also be relatively easy to implement anti-aliasing (probably in > ver
