* avcodec/trace_headers_bsf: also parse extradata in packet side dataJames Almer2021-08-14
| | | | | | | | | Certain mov/mp4 files have parameter sets out of band, and when required for a sample it may be propagated within the relevant packet's side data. This fixes parsing said files if the SPS and/or PPS in the side data is different than the one in extradata. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/cbs: add a helper to read extradata within packet side dataJames Almer2021-08-14
| | | | | | | | Using ff_cbs_read() on the raw buffer will not parse it as extradata, resulting in parsing errors for example when handling ISOBMFF avcC. This helper works around that. Signed-off-by: James Almer <jamrial@gmail.com>
* avformat/isom_tags: prefer in24 for 24bit PCM in MOVJan Ekström2021-08-14
| | | | | | | | | | | | | In 1c42fd93236e7869ef4d9fe3650dd3e951387321 the ipcm identifier was added in order to demux additional raw audio from Sony MP4 files. Unfortunately, it was not noticed that this same list is utilized for muxing as well, thus causing ipcm to get preferred compared to the identifier officially specified in QTFF documentation. This fixes the order of preference for 24bit PCM, where ipcm is still allowed, but in24 is the first match - thus being preferred. Fixes fate-acodec-pcm-s24be.

* hwcontext_vulkan: use GPU memcpy when copying to system RAMLynne2021-08-14
| | | | This should speed it up significantly on systems where it matters.
* imgutils: expose av_image_copy_plane_uc_from()Lynne2021-08-14
| | | | | | | | | | | | The reason why the generic av_image_copy_uc_from() doesn't really fit in the case for Vulkan is because some planes may be copied via other methods (such as mapping GPU memory), and if they don't satisfy the strict alignment requirements, a gpu image->gpu buffer->cpu ram copy is performed. We need this for hwcontext_vulkan, and I think this will also be useful to API users like libplacebo who would rather not write a custom SIMD memcpy.

* avfilter/formats: Factor common function combinations outAndreas Rheinhardt2021-08-13
| | | | | | | | | | | Several combinations of functions happen quite often in query_format functions; e.g. ff_set_common_formats(ctx, ff_make_format_list(sample_fmts)) is very common. This commit therefore adds functions that are equivalent to commonly used function combinations in order to reduce code duplication.

* lavc/qsvenc: allows the SDK runtime to choose LowPower/non-LowPower modesHaihao Xiang2021-08-12
| | | | | | | | | | | | | The SDK supports LowPower and non-LowPower modes, but some features are available only under one of the two modes. Currently non-LowPower mode is always chosen in FFmpeg if the mode is not set to LowPower explicitly. User will experience some SDK errors if a LowPower related feature is specified but the mode is not set to LowPower. With this patch, the mode is set to unknown by default in FFmpeg, the SDK is able to choose a workable mode for the specified features.

* avutil/mem: Reinline av_size_mult() internallyAndreas Rheinhardt2021-08-12
| | | | | | | | | | | | | Since 580e168a945b65100ec2c25433f33bfacfe9f7be, av_size_mult() is no longer inlined; on systems where interposing is a thing, this also inhibits the compiler from inlining said function into the internal callers of said function, although inlining such a small function is typically beneficial: With GCC 10.3 on Ubuntu x64 and -O3 this decreases the size of av_realloc_array from 91B to 23B, from 129B to 81B for av_realloc_f and from 77B to 23B for each of av_malloc_array, av_mallocz_array and av_calloc.

* qsvdec: add support for HW_DEVICE_CTX methodHaihao Xiang2021-08-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows user set hw_device_ctx instead of hw_frames_ctx for QSV decoders, hence we may remove the ad-hoc libmfx setup code from FFmpeg. "-hwaccel_output_format format" is applied to QSV decoders after removing the ad-hoc libmfx code. In order to keep compatibility with old commandlines, the default format is set to AV_PIX_FMT_QSV, but this behavior will be removed in the future. Please set "-hwaccel_output_format qsv" explicitly if AV_PIX_FMT_QSV is expected. The normal device stuff works for QSV decoders now, user may use "-init_hw_device args" to initialise device and "-hwaccel_device devicename" to select a device for QSV decoders. "-qsv_device device" which was added for workarounding device selection in the ad-hoc libmfx code still works For example: $> ffmpeg -init_hw_device qsv=qsv:hw_any,child_device=/dev/dri/card0 -hwaccel qsv -c:v h264_qsv -i input.h264 -f null - /dev/dri/renderD128 is actually open for h264_qsv decoder in the above command without this patch. After applying this patch, /dev/dri/card0 is used. $> ffmpeg -init_hw_device vaapi=va:/dev/dri/card0 -init_hw_device qsv=hw@va -hwaccel_device hw -hwaccel qsv -c:v h264_qsv -i input.h264 -f null - device hw of type qsv is not usable in the above command without this patch. After applying this patch, this command works as expected. Reviewed-by: Soft Works <softworkz@hotmail.com> Signed-off-by: James Almer <jamrial@gmail.com>
