Reset CropW/CropH from container without reset CropX/CropY might create some mismatch. 2. Width/Height from container can be larger than coded_width/coded_height. For example, mp4 container can apply a scaling after decoding. So decoder should only care about ES, while user can apply the info from container after decoding, like rotation, scaling and cropping. But it’s complex in practice. I don’t have idea for these issues. > ret = MFXVideoDECODE_QueryIOSurf(q->session, ¶m, &request); > if (ret < 0) > return ff_qsv_print_error(avctx, ret, "Error querying IO surface"); > -- > 2.34.1 > > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
