Summary of the bug:
My application extracts frames from h264 UDP stream and saves them as jpg
files.
Input pixel format is juv420p so mjpeg complains:
Incompatible pixel format 'yuv420p' for codec 'mjpeg', auto-selecting
format 'yuvj420p'
Adding filter to convert pixel format from yuv420p to yuvj420p solved the
problem, but since ffmpeg version n2.1 there is a new problem reported:
[swscaler @ 0xb12fea0] deprecated pixel format used, make sure you did set
range correctly
Deprecated pixel format message is observed in custom applications which
use ffmpeg libraries as well as in ffmpeg application.
How to reproduce:
{{{
% ffmpeg -i SOME_H264_STREAM output_%d.jpg
ffmpeg version: git-master, n2.1
built on: ubuntu 12.04
}}}
