Anton Khirnov	990e4a6639	Add a QSV decoding example.	10 years ago
Andreas Cadhalpun	078be09dd7	examples/demuxing_decoding: abort decoding when width, height or pix_fmt change This is necessary, because avcodec_decode_video2 can change width, height and/or pixel format of the AVCodecContext. Since video_dst_data and video_dst_linesize are not updated by calling av_image_alloc again, av_image_copy[_plane] asserts, because the destination buffer is too small. In this case, creating a useable rawvideo is not possible anyway, since it has fixed width/height/pix_fmt.

Clément Bœsch	b0352b1997	avcodec: export motion vectors in frame side data on demand The reasoning behind this addition is that various third party applications are interested in getting some motion information out of a video "for free" when it is available. It was considered to export other information as well (such as the intra information about the block, or the quantization) but the structure might have ended up into a half full-generic, half full of codec specific cruft. If more information is necessary, it should either be added in the "flags" field of the AVMotionVector structure, or in another side-data. This commit also includes an example exporting them in a CSV stream.	11 years ago
