[FFmpeg-user] mjpeg decoding problem

[Vincent,Wei]

Hi,
      As I know, the avi file format is use the CODEC_ID_MPEG4 as the codec,
so this may not support the MJPEG, you may
try the MPEG4 stream , or you can edit ffmpeg.c to change the codec type
,and rebuild the ffmpeg.

      AVOutputFormat avi_muxer = {
    "avi",
    "avi format",
    "video/x-msvideo",
    "avi",
    sizeof(AVIContext),
    CODEC_ID_MP2,
    CODEC_ID_MPEG4,
    avi_write_header,
    avi_write_packet,
    avi_write_trailer,
    .codec_tag= (const AVCodecTag*[]){codec_bmp_tags, codec_wav_tags, 0},
};
