FFmpeg / Avconv video playback problems - black or green tint
21 October 2014, by scottpatersonI am using FFmpeg / Avconv to convert a raw video file to a MP4 or AVI. Both FFmpeg and Avconv have the same problem.
-
The output video, both MP4 or AVI, play 100% percent perfect on Linux Mint in the default video player.
-
On Windows in WMP the MP4 plays, but the video is black, and the AVI plays and shows video but it has a green tint. On Windows in Quicktime both formats video is black.
Here is the command I am using:
avconv -i /home/scott/Desktop/out.wav -f rawvideo -pix_fmt rgb32 -s:v 540x240 -i
/home/scott/Desktop/out.raw -c:v libx264 -strict -2 -preset ultrafast -b:v 160k
/home/scott/Dropbox/code/out.avi-
I have spent a lot of time messing with the -pix_fmt and trying different pixel format, so far rgb32 returns the best results.
-
I have also tried -sws_flags options such as lanczos+accurate_rnd - but this did not help.
How can I get this to play the same in all video players?
Thanks!
