[Libav-user] pts problem

[Steffen.Roeber at hella.com]

I read many hours to understand pts in libav. But it seems there is no 
common simple way to retrieve.
I used the method from http://dranger.com/ffmpeg/. 

I do something like:
avcodec_decode_video2 (codecContext, frame, &got_picture_ptr, &p);
        uint64 pts = p.dts;
        if(pts == AV_NOPTS_VALUE && frame->opaque)
          pts = *(uint64_t *)frame->opaque;
        if (pts == AV_NOPTS_VALUE)
          pts = 0;

This approach works in some videos. But in my .divx videos I get a pts of 
3 in the first displayable frame., which is confusing for users which work 
on frame level.
So, does anybody know a better approach?
