I just write a ffcodec for ffmpeg. It can run success with my test codes, and also with ffmpeg test. However , when I tried use it in chrome, it run with some errors as following: [3845:3880:0710/110530.508867:ERROR:ffmpeg_video_decoder.cc(487)] avcodec_open2 failed.-558323010
[3845:3880:0710/110530.509921:ERROR:ffmpeg_video_decoder.cc(491)] avcodec_open2 error: Internal bug, should not have happened.

belowing is my ffcodec options for my decoder, can someone give some advice?:
