    1 On that AspectRatioHB.mpg file, if I do a avio_seek on the postion of the first frame and then update the timestamp (which is negative for that frame), on the first read using av_read_frame, you will not get that first frame packet. You will get some packet in the middle and that will produce incorrect results. It's like it skipped frames and the key first frame was never decoded. Also, if I do not seek on the file and just start reading, then all is good and I get the first packet correcly with negative timestamp etc.
