Using an IP cam, grabbing the h264 stream the picture looks fine. Want to use the MJPEG stream, but the image is washed out, lack of contrast, blacks show as dark gray and whites show as light gray. Chroma looks ok (bright blue is dull blue, yellow is yellow, etc). Problem evident in VLC, FFplay, FFmpeg.
ffplay rtsp://cam/h264/stream
Stream #0:0: Video: h264 (Baseline), yuv420p(progressive), 1280x720, 30 fps, 30 tbr, 90k tbn, 180k tbc
ffplay rtsp://cam/mjpeg/stream
Stream #0:0: Video: mjpeg, yuvj422p(pc, bt470bg/unknown/unknown), 1280x720 [SAR 1:1 DAR 16:9], 30 fps, 30 tbr, 90k tbn, 90k tbc
If the cam is mis-reporting its scale or colorspace, are there ways to override? I tried this, had no effect on the picture:
ffmpeg -i rtsp://cam/mjpeg/stream -vf scale=in_range=tv -f matroska - | ffplay -
Any advice appreciated!
My ffmpeg version is upgraded to 4.1-win64-static, was 3.4.
-vf setparams=range=tv
(No such filter: 'setparams');-setparams range=tv
(Unrecognized option 'setparams').-vf setparams=range=tv
is accepted as a parameter with current version. If you answer the question I'll mark it as accepted.
