Thank you very much. I download a .mov file from
http://www.hd-trailers.net/movie/rogue-one-a-star-wars-story/, but get the same
result, avcodec_open2 returns -1.
Function av_dump_format gives .mov file information as :
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '1.mov':

I tried the stream address rtmp://live.hkstv.hk.lxdns.com/live/hks, the video
stream has the type of h264. avcodec_open2 returns -1.
av_dump_format print as:
Input #0, flv, from 'rtmp://live.hkstv.hk.lxdns.com/live/hks':

Is the h264 file you are using available online to test against?
I have been using the h264 film trailers from here
http://www.hd-trailers.net/movie/rogue-one-a-star-wars-story/
And they open and play without issue. Do you get the same issue with your
software using one of these clips?
You may need to post your function that opens a stream up to the point where
you call avcodec_open2()...

In transcoding project of LeiXiaoHua(demo of usage of filters), if I use media
file with h264 video stream as input file, the function avcodec_open2 will
return -1. Media file with video stream in other format, such as mpeg4, mjpeg
return 0 (OK). Why ? Someone meets the same problem?
