Hi all, I have a problem getting the correct width/height with a few video files.
After avformat_open_input(), the AVCodecContext entries for the video stream report the following: width/height: 1920x1080 coded_width/coded_height: 1920x1088 The difference of 8 pixels in height is presumably used to get a multiple of 16. But after calling avcodec_open() for that AVCodecContext, both value pairs report the same: width/height: 1920x1088 coded_width/coded_height: 1920x1088 Using these width/height values results in additional 8 gray pixel lines at the bottom of each displayed frame. This also happens with FFplay (from 0.8.5). As a workaround, I now save the initial width/height information and use that if it differs from the values after avcodec_open(). But is that correct? Will this break in the future? FFplay does not seem to use coded_width/coded_height at all. Does this mean a video player program should always only use width/height? What should be done when the two differ? Martin _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
