| | | | | | | This is consistent with -stats_mux* As the options were added very recently, this should not break any users.

* avutil/{color_utils, csp}: merge color_utils into csp and expose APILeo Izen2023-02-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | libavutil/color_utils contains some avpriv_ symbols that map enum AVTransferCharacteristic values to gamma-curve approximations and to the actual transfer functions to invert them (i.e. -> linear). There's two issues with this: (1) avpriv is evil and should be avoided whenever possible (2) libavutil/csp.h exposes a public API for handling color that already handles primaries and matricies I don't see any reason this API has to be private, so this commit takes the functionality from avutil/color_utils and merges it into avutil/csp with an exposed av_ API rather than the previous avpriv_ API. Every reference to the previous API has been updated to point to the new one. color_utils.h has been deleted as well. This should not break any applications as it only contained avpriv_ symbols in the first place, so nothing in that header could be referenced by other applications.

* fftools/ffmpeg: add an option for writing pre-muxing statsAnton Khirnov2023-02-091-4/+9
| | | | | | Analogous to -enc_stats*, but happens right before muxing. Useful because bitstream filters and the sync queue can modify packets after encoding and before muxing. Also has access to the muxing timebase.
* avformat/hls: Add option to retry failed segments for hlsgnattu2023-02-091-0/+4
| | | | | | | | | | | Current HLS implementation simply skip a failed segment to catch up the stream, but this is not optimal for some use cases like livestream recording. Add an option to retry a failed segment to ensure the output file is a complete stream. Signed-off-by: gnattu <gnattuoc@me.com> Reviewed-by: Steven Liu <liuqi05@kuaishou.com>
* lavc/decode: allow using AV_CODEC_FLAG_COPY_OPAQUE for decodingAnton Khirnov2023-02-041-0/+3
| | | | | Use it to propagate AVPacket.opaque[_ref] to corresponding AVFrame fields. This is a more convenient alternative to reordered_opaque.

* ffmpeg: add video heartbeat capability to fix_sub_durationJan Ekström2023-02-031-0/+16
| | | | | | | | | | | | | | | | | | | Splits the currently handled subtitle at random access point packets that can be configured to follow a specific output stream. Currently only subtitle streams which are directly mapped into the same output in which the heartbeat stream resides are affected. This way the subtitle - which is known to be shown at this time can be split and passed to muxer before its full duration is yet known. This is also a drawback, as this essentially outputs multiple subtitles from a single input subtitle that continues over multiple random access points. Thus this feature should not be utilized in cases where subtitle output latency does not matter.

* avfilter: add VA-API variants of the stack filtersHaihao Xiang2023-01-301-0/+81
| | | | | | | | | | | | | | | | | | | 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>
* lavc/encode: pass through frame durations to encoded packetsAnton Khirnov2023-01-291-2/+2
| | | | | | The generic code can only handle the no-delay case. Encoders with delay need to be handled individually, which will be done in the following commits.
* lavc: add a codec flag for propagating opaque from frames to packetsAnton Khirnov2023-01-291-0/+3
| | | | | | | | | This is intended to be a more convenient replacement for reordered_opaque. Add support for it in the two encoders that offer AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE: libx264 and libx265. Other encoders will be supported in future commits.

* avfilter/palette{gen,use}: revert support palettes with alphaClément Bœsch2023-01-031-8/+0
| | | | | | | | | | | | | | | | | | | | | | | This reverts commit dea673d0d548c864ec85f9260d8900d944ef7a2a. This change cannot work for several reasons, the most obvious ones are: - the alpha is being part of the scoring of the color difference, even though we can not interpret the alpha as part of the perception of the color (we don't even know if it's premultiplied or postmultiplied) - the colors are averaged with their alpha value which simply cannot work The command proposed in the original thread of the patch actually produces a completely broken file: ffmpeg -y -loglevel verbose -i fate-suite/apng/o_sample.png -filter_complex "split[split1][split2];[split1]palettegen=max_colors=254:use_alpha=1[pal1];[split2][pal1]paletteuse=use_alpha=1" -frames:v 1 out.png We can see that many color pixels are off, but more importantly some colors have a random alpha value: https://imgur.com/eFQ2UK7 I don't see any easy fix for this unfortunately, the approach appears to be flawed by design.
