* avcodec/omx: Remove remnants of old preallocated buffersAndreas Rheinhardt2021-06-08
| | | | | | | | | There are no preallocated buffer packets any more; this feature only worked with the old encode API and only until said API was turned into a wrapper for the new API in 93016f5d1d280f9cb7856883af287fa66affc04c. So remove its remnants. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/dvenc: Avoid copying packet data, allow user-supplied buffersAndreas Rheinhardt2021-06-08
| | | | | | | | | | | | When the packet size is known in advance like here, one can avoid an intermediate buffer for the packet data; this also makes it easy to allow user-supplied buffers. Only one thing needed to be changed: The earlier code relied on the buffer having been initially zeroed by av_fast_padded_malloc(), so one now needs to zero the packet at first.

* avcodec/nvenc: add option to disable all extra SEI dataTimo Rothenpieler2021-06-06
| | | | | | | | | | | With these triggering a lot of crashes recently, an option to globally disable all of them is added as a tool to work around those crashes in case the SEI data is not needed by the user. Also re-enables s12m for hevc_nvenc, since the issue is not specifically with that, but it affects all SEI data. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* pixfmt: fixed wrong fix of commentValerii Zapodovnikov2021-06-02
| | | | | | | | | | | | This mostly reverts 785bfb1d7bb8de567c3aac1d9cc369b55ac9fb7b. But I also added some clarifications so that nobody mixes primaries with matrix again. SMPTE 240 and 170 primaires are the same, while matrix coeff. are different, because 240 is derived from 170's new primaries and white point while 170 uses BT.601 derived from BT.470 System M (yes, with Illuminant C) a.k.a. NTSC 1953. Some nits too. Reviewed-by: Reto Kromer <lists@reto.ch> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
