* lavc/vaapi_encode_h264: add "coder" option supportJun Zhao2017-08-20
| | | | | | | | | | Follow libx264 style to support "coder" option, and set it to cabac by default. Signed-off-by: Yi A Wang <yi.a.wang@intel.com> Signed-off-by: Jun Zhao <jun.zhao@intel.com> Reviewed-by: Steven Liu <lingjiujianke@gmail.com> Signed-off-by: Mark Thompson <sw@jkqxz.net>
* vaapi_encode: Move quality option to common codeMark Thompson2017-08-20
| | | | | | | | | | | Use AVCodecContext.compression_level rather than a private option, replacing the H.264-specific quality option (which stays only for compatibility). This now works with the H.265 encoder in the i965 driver, as well as the existing cases with the H.264 encoder. (cherry picked from commit 19388a7200e5d99c703271f05dba1c806720e808)

* opus_pvq_search: Restore the proper use of conditional define and simplify ↵Ivan Kalvachev2017-08-19
| | | | | | | | | | | | | | the function name suffix handling. Using named define properly documents the code paths. It also avoids passing additional numbered arguments through multiple levels of macro templates. The suffix handling is done by concatenation, like in other asm functions and avoid having two separate "cglobal" defines. Signed-off-by: Ivan Kalvachev <ikalvachev@gmail.com>

The exact version is as fast or faster on newer CPUs (which EXTERNAL_AVX_FAST describes well) whilst the non-exact version is faster than the exact on older CPUs. Also fixes yasm compilation which doesn't accept !cpuflags(avx) syntax. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* speedhq: fix behavior of single-field decodingSteinar H. Gunderson2017-08-03
| | | | | | | | | | The height convention for decoding frames with only a single field made sense for compatibility with legacy decoders, but doesn't really match the convention used by NDI, which is the primary (only?) user. Thus, change it to simply assuming that if the two fields overlap, the frame is meant to be a single field and the frame height matches the field height.
