[FFmpeg-devel] vcodec_open2 error: Internal bug, should not have happened

[听，天边的歌]

I am trying to implement the OpenMax IL Video Decoder on ffmpeg. But I meet some problems. When I use the codec with ffmpeg on Chrome by force, it raised a error of bug
ffmpeg_video_decoder.cc(491)] avcodec_open2 error: Internal bug, should not have happened
I 'm not familiar with the version of ffmpeg in the last serveral years. My codec can run success when using 
./ffmpeg -c:v h264_omxcodec -i test1.mp4 output_video.mp4
and I haven't find out how to enable logging of ffmpeg on Chrome(I don't know why av_log_set_callback() is useless when I used it),
so Is there anyone can give me some advices?


Thx a lot.


The FFCodec is used as following: 


#define OFFSET(x) offsetof(OMXCodecDecoderContext, x)
#define VDE AV_OPT_FLAG_VIDEO_PARAM | AV_OPT_FLAG_DECODING_PARAM | AV_OPT_FLAG_ENCODING_PARAM
#define VE  AV_OPT_FLAG_VIDEO_PARAM | AV_OPT_FLAG_ENCODING_PARAM
#define VD  AV_OPT_FLAG_VIDEO_PARAM | AV_OPT_FLAG_DECODING_PARAM
