Too bad. Havn't found the right discussion yet and I haven't tested
the cur_dts yet. However I think it is really bad this information
shall be so difficult to find.
I think the ffmpeg project needs some proper system description !
My original question was why I got unordered pts values using
avcodec_decode_video(m_pVideoCodecCtx, m_pFrame, &frameFinished,
packet.data, packet.size) in the m_pFrame struct ? Please can someone
answer this if the images I get are unsorted then ?
