| | | | | | | | | | | | | | It results in undefined behaviour. Instead initialize the mutexes and condition variables once during init (and check these initializations). Also combine the corresponding mutex and condition variable into one structure so that one can allocate their array jointly.

* Makefile: Prompt for reconfigure on lavc/hwaccels.h modificationAndreas Rheinhardt2022-07-01
| | | | | | | | | | | | | | | | Adding a new AVHWAccel also adds a new CONFIG variable for it and said config variables are typically used to calculate the size of stack arrays. In such a context, an undefined CONFIG variable does not evaluate to zero; instead it leads to a compilation failure. Therefore treat this file like the other files containing lists of configurable components and prompt for reconfiguration if it is modified. (E.g. a44fba0b5b3b4090f9238751736198ddd1f0f1d5 led to compilation failures for me.) Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

As an existing example, the MPEG-TS muxer already requires the AC-3 parser, and in order to fix existing issues with the current AC-3 movenc code, switching to use the AC-3 parser is required, so this is an enabling change for that.

| | | | | | | | | | | | | | | | | | | | Update the still AVIF parser to only read the primary item. With this patch, AVIF still images with exif/icc/alpha channel will no longer fail to parse. For example, this patch enables parsing of files in: https://github.com/AOMediaCodec/av1-avif/tree/master/testFiles/Microsoft Adding two fate tests: 1) demuxing of still image with 1 item - this test will pass regardless of this patch. 2) demuxing of still image with 2 items - this test will fail without this patch and will pass with patch applied.

* avformat/hlsenc: Use HLS version 2 if rounded durations are enabledLucy2022-06-29
| | | | | | | | | | | | | | | | | This allows for wider compatibility with older devices, such as those running iOS 3. The only difference between HLS version 2 and version 3 is that version 3 supports non-integer EXTINF values, and as such, we can default to version 2 if we're using whole-integer EXTINFs anyways, when `-hls_flags round_durations` is set. As this code seems to otherwise consistently use the lowest compatible version, this seems to fit in properly with existing behavior. Testing confirms with that this patch, HLS output can work all the way back to iOS 3. Reviewed-by: Steven Liu <liuqi05@kuaishou.com> Signed-off-by: Lucy <lucy@absolucy.moe>

* avformat/movenc: Support alpha channel for AVIFVignesh Venkatasubramanian2022-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AVIF specification allows for alpha channel as an auxiliary item (in case of still images) or as an auxiliary track (in case of animated images). Add support for both of these. The AVIF muxer will take exactly two streams (when alpha is present) as input (first one being the YUV planes and the second one being the alpha plane). The input has to come from two different images (one of it color and the other one being alpha), or it can come from a single file source with the alpha channel extracted using the "alphaextract" filter. Example using alphaextract: ffmpeg -i rgba.png -filter_complex "[0:v]alphaextract[a]" -map 0 -map "[a]" -still-picture 1 avif_with_alpha.avif Example using two sources (first source can be in any pixel format and the second source has to be in monochrome grey pixel format): ffmpeg -i color.avif -i grey.avif -map 0 -map 1 -c copy avif_with_alpha.avif The generated files pass the compliance checks in Compliance Warden: https://github.com/gpac/ComplianceWarden libavif (the reference avif library) is able to decode the files generated using this patch. They also play back properly (with transparent background) in: 1) Chrome 2) Firefox (only still AVIF, no animation support) Reviewed-by: James Zern <jzern@google.com> Signed-off-by: Vignesh Venkatasubramanian <vigneshv@google.com>
* fftools/ffplay: fix YUV conversion modeNiklas Haas2022-06-27
| | | | | | | | | | | | | | GL and Metal cache the state at time of texture creation. GLES2 and Direct3D 11 use the state at time of the render copy call. So the only way we can get the correct behavior consistently is by making sure the state is set for both the upload *and* the draw call. This probably isn't our bug to fix (upstream should make itself behave consistently and also document its functions), but as it stands, `ffplay` is misrendering BT.709 as BT.601 on my stock Linux system, and that leaves a bad taste in my mouth.
