* opus_pvq_search: split functions into exactness and only use the exact if ↵Rostislav Pehlivanov2017-08-18
| | | | | | | | | | | | its faster This splits the asm function into exact and non-exact version. 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>

* h264: Add support for alternative transfer characterics SEIVittorio Giovara2017-08-10
| | | | | | | | | | The use of this SEI is for backward compatibility in HLG HDR systems: older devices that cannot interpret the "arib-std-b67" transfer will get the compatible transfer (usually bt709 or bt2020) from the VUI, while newer devices that can interpret HDR will read the SEI and use its value instead.

* 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.

| | | | | | | | | | | | | | | | | | | | This commit switches off forced correct nesting of tags and only keeps it for font tags. See long explanations in the code for the rationale. This results in various FATE changes which I'll explain here: - various swapping in font attributes, this is mostly noise due to the old reverse stack way of printing them. The new one is more correct as the last attribute takes over the previous ones. - unrecognized tags disappears - invalid tags that were previously displayed aren't anymore (instead, we have a warning). This is better for the end user The main benefit of this commit is to be more tolerant to error, leading to a better handling of badly nested tags or random wrong formatting for the end user.
