* configure: select subordinate formats for HLSGyan Doshi2023-02-18
| | | | | | | | HLS segments may be MPEG-TS or fragmented MP4, so those (de)muxers are required for reading/writing HLS media segments. Fixes functionality with --disable-everything --enable-demuxer=hls --enable-muxer=hls
* avfilter: add QSV variants of the stack filtersHaihao Xiang2023-02-16
| | | | | | | | | | | | | | | | | | | Include hstack_qsv, vstack_qsv and xstack_qsv. They may accept input streams with different sizes. Examples: $ ffmpeg -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -filter_complex "[0:v][0:v]hstack_qsv" -f null - $ ffmpeg \ -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -hwaccel qsv -hwaccel_output_format qsv -i input.mp4 \ -filter_complex "[0:v][1:v][2:v][3:v]xstack_qsv=inputs=4:fill=0x000000:layout=0_0_1920x1080|w0_0_1920x1080|0_h0_1920x1080|w0_h0_1920x1080" \ -f null - Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>

* avformat/avformat: Move AVOutputFormat internals out of public headerAndreas Rheinhardt2023-02-09
| | | | | | | | | | | | | | This commit does for AVOutputFormat what commit 20f972701806be20a77f808db332d9489343bb78 did for AVCodec: It adds a new type FFOutputFormat, moves all the internals of AVOutputFormat to it and adds a now reduced AVOutputFormat as first member. This does not affect/improve extensibility of both public or private fields for muxers (it is still a mess due to lavd).

* lavc: deprecate CrystalHD decodersAnton Khirnov2023-02-04

* lavfi/deinterlace_qsv: simplify deinterlace_qsv filterHaihao Xiang2023-02-03
| | | | | | | Like what we did for scale_qsv filter, we use QSVVPPContext as a base context to manage MFX session for deinterlace_qsv filter. Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>

* lavfi/scale_qsv: simplify scale_qsv filterHaihao Xiang2023-01-30
| | | | | | | | | | | | Use QSVVPPContext as a base context of QSVScaleContext, hence we may re-use functions defined for QSVVPPContext to manage MFX session for scale_qsv filter. In addition, system memory has been taken into account in QSVVVPPContext, we may add support for non-QSV pixel formats in the future. Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>
* avfilter: add VA-API variants of the stack filtersHaihao Xiang2023-01-30
| | | | | | | | | | | | | | | | | | | Include hstack_vaapi, vstack_vaapi and xstack_vaapi. They may accept input streams with different sizes. libva2 (VA-API 1.0+) is required. Example: $ ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -i input.h265 -filter_complex "[0:v][0:v]hstack_vaapi" -c:v h264_vaapi out.h264 $ ffmpeg \ -hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \ -hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \ -hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \ -hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \ -filter_complex "[0:v][1:v][2:v][3:v]xstack_vaapi=inputs=4:fill=0x000000:layout=0_0_1920x1080|w0_0_1920x1080|0_h0_1920x1080|w0_h0_1920x1080" \ -c:v hevc_vaapi out.h265 Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>

* configure: Add (h264|hevc)_sei subsystemsAndreas Rheinhardt2022-12-01
| | | | | | | | | | | | | | | | | | Currently, several components select atsc_a53, despite not using anything from it themselves. They only select it because parsing SEI messages adds an indirect dependency. But using direct dependencies is more natural, so add dedicated subsystems for them. It already allows to remove a superfluous dependency of the HEVC QSV encoder on hevc_sei and atsc_a53. Adding new subsystems only becomes effective after a reconfiguration. In order to force this, some needed headers (which are only included implicitly before this commit) were included explicitly in libavformat/allformats.c.

* avcodec/vc1dec: Remove VC-1 decoders->H.263 decoder dependencyAndreas Rheinhardt2022-11-06
| | | | | | | | | | | | | | The only thing from the H.263 decoder that is reachable by the VC-1 decoder is ff_h263_decode_init(); but it does not even use all of it; e.g. h263dsp is unused and so are the VLCs initialized in ff_h263_decode_init() (they amount to about 77KB which are now no longer touched). Notice that one could also call ff_idctdsp_init() directly instead of ff_mpv_idct_init(); one could even do so in ff_vc1_init_common().

* avcodec/vc1dec: Split VC-1 decoders from msmpeg4Andreas Rheinhardt2022-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only msmpeg4 code that is ever executed by the VC-1 based decoders is ff_msmpeg4_decode_init() and what is directly reachable from it. This is: a) A call to av_image_check_size(), then ff_h263_decode_init(), b) followed by setting [yc]_dc_scale_table and initializing scantable/permutations. c) Afterwards, some static tables are initialized. d) Finally, slice_height is set. The replacement for ff_msmpeg4_decode_init() performs a) just like now; it also sets [yc]_dc_scale_table, but it only initializes inter_scantable and intra_scantable and not permutated_intra_[hv]_scantable: The latter are only used inside decode_mb callbacks which are only called in ff_h263_decode_frame() which is unused for VC-1.* The static tables initialized in c) are not used at all by VC-1 (the ones that are used have been factored out in previous commits); this avoids touching 327KiB of .bss. slice_height is also not used by the VC-1 decoder (setting it in ff_msmpeg4_decode_init() is probably redundant after b34397b4cd780b5692548e7d021ec884c7217dba). *: It follows from this that the VC-1 decoder is not really based upon the H.263 decoder either; changing this will be done in a future commit.
