* lavu/buffer: add a convenience function for replacing buffersAnton Khirnov2020-09-283-1/+43
| | | | | | | A common pattern e.g. in libavcodec is replacing/updating buffer references: unref old one, ref new one. This function allows simplifying such code and avoiding unnecessary refs+unrefs if the references are already equivalent.
* avutil/pixfmt: improve definition of AVColorRangeJan Ekström2020-09-231-3/+51
| | | | | | | | | | | | As it was brought up that the current documentation leaves things as specific to YCbCr only, ICtCp and RGB are now mentioned. Additionally, the specifications on which these definitions of narrow and full range are defined are mentioned. This way, the documentation of AVColorRange should now match how most people seem to read interpret it at this point, and thus flagging RGB AVFrames as full range is valid not only according to common sense, but also the enum definition.

* avutil/timecode: fix av_timecode_get_smpte_from_framenum with 50/60 fpsMarton Balint2020-09-132-18/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SMPTE 12M timecode can only count frames up to 39, because the tens-of-frames value is stored in 2 bit. In order to resolve this 50/60 fps SMPTE timecode is using the field bit (which is the same bit as the phase correction bit) to signal the least significant bit of a 50/60 fps timecode. See SMPTE ST 12-1:2014 section 12.1. Therefore we slightly change the format of the return value of av_timecode_get_smpte_from_framenum and AV_FRAME_DATA_S12M_TIMECODE and start using the previously unused Phase Correction bit as Field bit. (As the SMPTE standard suggests) We add 50/60 fps support to av_timecode_get_smpte_from_framenum by calling the recently added av_timecode_get_smpte function in it which already handles this properly. This change affects the decklink indev and the DV and MXF muxers. MXF has no fate test for 50/60fps content, DV does, therefore the changes. MediaInfo (a recent version) confirms that half-frame timecode must be inserted to DV. MXFInspect confirms valid timecode insertion to the System Item of MXF files. For MXF, also see EBU R122. Note that for DV the field flag is not used because in the HDV specs (SMPTE 370M) it is still defined as biphase mark polarity correction flag. So it should not matter that the DV muxer overrides the field bit. Signed-off-by: Marton Balint <cus@passwd.hu>
* hwcontext_vaapi: Don't require a render node when deriving from DRMMark Thompson2020-08-311-12/+16
| | | | | | | | | | | | | The V4L2 driver does not actually have an associated DRM device at all, so users work around the requirement by giving libva an unrelated display-only device instead (which is fine, because it doesn't actually do anything with that device). This was broken by bc9b6358fb7315c0173de322472641766f6289da forcing a render node, because the display-only device did not have an associated render node to use. Fix that by just passing through the original non-render DRM fd if we can't find a render node.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Requires some extraneous top side and bottom front channels to be defined. According to STD-B59v2, the defined channel layout is: - FL - FR - FC - LFE1 - BL - BR - FLc - FRc - BC - LFE2 - SiL - SiR - TpFL - TpFR - TpFC - TpC - TpBL - TpBR - TpSiL - TpSiR - TpBC - BtFC - BtFL - BtFR
* hwcontext_vulkan: remove plane size alignment checks when host importingLynne2020-08-021-4/+4

* hwcontext_vaapi: remove duplicate formats from sw_format listHaihao Xiang2020-07-271-5/+25
| | | | | | | | | | | | | | | | | | | | | | hwcontext_vaapi maps different VA fourcc to the same pix_fmt for U/V plane swap cases, however duplicate formats are not expected in sw_format list when merging formats. For example: ffmpeg -loglevel debug -init_hw_device vaapi -filter_hw_device vaapi0 \ -f lavfi -i smptebars -vf \ "hwupload=derive_device=vaapi,scale_vaapi,hwdownload,format=yuv420p" \ -vframes 1 -f null - Without this fix, an auto scaler is required for the above command Duplicate formats in ff_merge_formats detected [auto_scaler_0 @ 0x560df58f4550] Setting 'flags' to value 'bicubic' [auto_scaler_0 @ 0x560df58f4550] w:iw h:ih flags:'bicubic' interl:0 [Parsed_hwupload_0 @ 0x560df58f0ec0] auto-inserting filter 'auto_scaler_0' between the filter 'graph 0 input from stream 0:0' and the filter 'Parsed_hwupload_0' Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>

* libavutil: Detect MMI and MSA flags for MIPSJiaxun Yang2020-07-237-1/+181
| | | | | | | | | | | | | | | Add MMI & MSA runtime detection for MIPS. Basically there are two code pathes. For systems that natively support CPUCFG instruction or kernel emulated that instruction, we'll sense this feature from HWCAP and report the flags according to values grab from CPUCFG. For systems that have no CPUCFG (or not export it in HWCAP), we'll parse /proc/cpuinfo instead.
