[Libav-user] how to encode avframe as jpeg format

[qw]

Hi,


Long time ago, PIX_FMT_YUVJ420P is used as input format to jpeg encoder. Current ffmpeg version suggests 'PIX_FMT_YUVJ420P  planar YUV 4:2:0, 12bpp, full scale (JPEG), deprecated in favor of PIX_FMT_YUV420P and setting color_range'.


If PIX_FMT_YUV420P is used as input format, how to set color_range for jpeg encoder? Where can I find jpeg encoding example?


Thanks!


B.R.
