* lavfi/dnn: Use uint8_t for async and do_ioproc in TaskItemsShubhanshu Saxena2021-06-12

* doc: fix generating doxy with out-of-tree buildsAnton Khirnov2021-06-11
| | | | | | Broken in 753930bc7300dd595c4bab51c5a70d1da9083da4, as the path to Doxyfile passed to doxy-wrapper.sh is relative to the build dir, while the recipe cd's to the source dir before invoking the wrapper.
* avcodec/cuviddec: correctly set key_frame with interlaced contentstuhlo2021-06-11
| | | | | | | | | | | Fixes #9283 This fixes setting of 'key_frame' flag in AVFrame when input h264 packets represents individual fields of interlaced video. In this case, pairs of two consecutive fields represents a single decoded picture and have identical 'CurrPicIdx', however, only the first field is entirely intra-coded and has the flag 'intra_pic_flag' set and the second field was resetting the flag before it was even read in the function 'cuvid_output_frame'.
