* avcodec: use the new AVFrame interlace flags in all decoders and encodersJames Almer2023-05-041-1/+2
| | | | Signed-off-by: James Almer <jamrial@gmail.com>
* lavc: support AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE in all no-delay encodersAnton Khirnov2023-01-291-1/+1
| | | | Including fake-delay encoders marked with FF_CODEC_CAP_EOF_FLUSH.
* avcodec/blockdsp: Remove unused AVCodecContext parameterAndreas Rheinhardt2022-09-211-1/+1
| | | | | | | Possible since be95df12bb06b183c8d2aea3b0831fdf05466cf3. Reviewed-by: Rémi Denis-Courmont <remi@remlab.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/codec_internal: Add macro to set AVCodec.long_nameAndreas Rheinhardt2022-09-031-1/+1
| | | | | | | | It reduces typing: Before this patch, there were 105 codecs whose long_name-definition exceeded the 80 char line length limit. Now there are only nine of them. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec: Make init-threadsafety the defaultAndreas Rheinhardt2022-07-181-1/+1
| | | | | | | | | | | and remove FF_CODEC_CAP_INIT_THREADSAFE All our native codecs are already init-threadsafe (only wrappers for external libraries and hwaccels are typically not marked as init-threadsafe yet), so it is only natural for this to also be the default state.

* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-151-2/+3
| | | | | | | | | | | | | | | | | | This is more spec-compliant because it does not rely on dead-code elimination by the compiler. Especially MSVC has problems with this, as can be seen in https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/296373.html or https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/297022.html This commit does not eliminate every instance where we rely on dead code elimination: It only tackles branching to the initialization of arch-specific dsp code, not e.g. all uses of CONFIG_ and HAVE_ checks. But maybe it is already enough to compile FFmpeg with MSVC with whole-programm-optimizations enabled (if one does not disable too many components).

* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-051-1/+1
| | | | | | | | | | | This is possible, because every given FFCodec has to implement exactly one of these. Doing so decreases sizeof(FFCodec) and therefore decreases the size of the binary. Notice that in case of position-independent code the decrease is in .data.rel.ro, so that this translates to decreased memory consumption.

* avcodec/internal: Move FF_SIGNBIT and ff_log2_run to mathops.hAndreas Rheinhardt2022-03-211-1/+1
| | | | | | | It is a more fitting place for them. Also move the definition of ff_log2_run to mathtables.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/codec_internal: Rename AVCodecDefault->FFCodecDefaultAndreas Rheinhardt2022-03-211-1/+1
| | | | | | | This structure is no longer declared in a public header, so using an FF-prefix is more appropriate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-211-9/+9
| | | | | | | | | | | | | | | | Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

* avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.hAndreas Rheinhardt2022-03-211-0/+1
| | | | | | | | | | Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault. This reduces the amount of files that have to include internal.h (which comes with quite a lot of indirect inclusions), as e.g. most encoders don't need it. It is furthemore in preparation for moving the private part of AVCodec out of the public codec.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/dnxhdenc: Fix segfault when using too many slice threadsAndreas Rheinhardt2021-05-101-1/+1
| | | | | | | | | | | | | | The DNXHD encoder's context contains an array of 32 pointers to DNXHDEncContexts used in case of slice threading; when trying to use more than 32 threads with slice threading, the encoder's init function errors out, but the close function takes avctx->thread_count at face value and tries to free inexistent elements of the array, leading to potential crashes. Fix this by modifying the check used to decide whether the slice contexts should be freed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/dnxhdenc: Avoid copying packet data, allow user-supplied buffersAndreas Rheinhardt2021-05-051-2/+4
| | | | | | | | When the packet size is known in advance like here, one can avoid an intermediate buffer for the packet data by using ff_get_encode_buffer() and also set AV_CODEC_CAP_DR1 at the same time. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-271-1/+1
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.
