* avcodec: Make init-threadsafety the defaultAndreas Rheinhardt2022-07-18
| | | | | | | | | | | 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.

* avcodec/mjpegenc: support writing ICC profilesNiklas Haas2022-04-11
| | | | | | | | | | | | | | | | This is mostly straightforward. The major complication is that, as a result of the 16-bit chunk size limitation, ICC profiles may need to be split up into multiple chunks. We also need to make sure to allocate enough extra space in the packet to fit the ICC profile, so modify both mpegvideo_enc.c and ljpegenc.c to take into account this extra overhead, failing cleanly if necessary. Also add a FATE transcode test to ensure that the ICC profile gets written (and read) correctly. Note that this ICC profile is smaller than 64 kB, so this doesn't test the APP2 chunk re-arranging code at all. Signed-off-by: Niklas Haas <git@haasn.dev>
* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-05
| | | | | | | | | | | 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/mjpegenc: Fix files with slices > 1, but threads == 1Andreas Rheinhardt2022-04-01
| | | | | | | | | | | | | | | | | In the aforementioned case mpegvideo_enc.c calls ff_mjpeg_encode_stuffing() at the end of every line which pads the output to byte-alignment and escapes it; yet it does not write the restart-markers (and also not the DRI marker when writing the header) and so the output files are broken. Fix this by writing these markers depending upon the number of slices and not the number of threads in use; this also makes the output of the encoder reproducible given a slice count and is therefore important if encoder tests that actually use -threads auto are added in the future.

* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-21
| | | | | | | | | | | | | | | | 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 Rheinhardt2022-03-21
| | | | | | | | | | 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/jpegtables: Unavpriv MJPEG-tablesAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | | There are seven MJPEG-tables, five small (1x12, 4x17) and two not small (2x162). These are all avpriv, despite this not being worthwhile due to the overhead of exporting a symbol: The total overhead for each symbol consists of two entries in .dynsym (24B each), one entry in the importing library's .rela.dyn (24B) and one in .got (8B) as well as 2x2B for symbol versions and 4B for symbol hashes in the exporting library; in addition to that, the name of the symbol is included in both exporting and importing libraries, using 2x210 bytes in this case. (The above numbers are for a x64 Elf/Linux/GNU system. Other platforms will give different numbers.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/encode: Always use intermediate buffer in ff_alloc_packet2()Andreas Rheinhardt2021-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, ff_alloc_packet2() has a min_size parameter: It is supposed to be a lower bound on the final size of the packet to allocate. If it is not too far from the upper bound (namely, if it is at least half the upper bound), then ff_alloc_packet2() already allocates the final, already refcounted packet; if it is not, then the packet is not refcounted and its data only points to a buffer owned by the AVCodecContext (in this case, the packet will be made refcounted in encode_simple_internal() in libavcodec/encode.c). The goal of this was to avoid data copies and intermediate buffers if one has a precise lower bound. Yet those encoders for which precise lower bounds exist have recently been switched to ff_get_encode_buffer() (which automatically allocates final buffers), leaving only two encoders to actually set the min_size to something else than zero (namely aliaspixenc and hapenc). Both of these encoders use a very low lower bound that is not helpful in any nontrivial case. This commit therefore removes the min_size parameter as well as the codepath in ff_alloc_packet2() for the allocation of final buffers. Furthermore, the function has been renamed to ff_alloc_packet() and moved to encode.h alongside ff_get_encode_buffer(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/mjpegenc: Include all supported pix_fmts in mpegenc pix_fmtsAndreas Rheinhardt2021-04-10
| | | | | | | | | | | | | | | Currently said list contains only the pixel formats that are always supported irrespective of the range and the value of strict_std_compliance. This makes the MJPEG encoder an outlier as all other codecs put all potentially supported pixel formats into said list and error out if the chosen pixel format is unsupported. This commit brings it therefore in line with the other encoders. The behaviour of fftools/ffmpeg_filter.c has been preserved. A more informed decision would be possible if colour range were available at this point, but it isn't. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/ljpegenc: Allow full range yuv420p, yuv422p, yuv444p by defaultAndreas Rheinhardt2021-04-10
| | | | | | | | | | | | | The documentation for AV_PIX_FMT_YUVJ420P reads: "planar YUV 4:2:0, 12bpp, full scale (JPEG), deprecated in favor of AV_PIX_FMT_YUV420P and setting color_range" Yet the LJPEG encoder only accepts full scale yuv420p when strictness is set to unofficial or lower; with default strictness it emits a nonsense error message that says that limit range YUV is unofficial. This has been changed to allow full range yuv420p, yuv422p and yuv444p irrespective of the level of strictness. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Remove cumbersome way of checking for amount of bytes leftAndreas Rheinhardt2021-03-30
| | | | | | | | | | | | | Several encoders used code like the following to check for the amount of bytes left in a PutBitContext: pb->buf_end - pb->buf - (put_bits_count(pb) >> 3) Besides the fact that using the pointers directly might pose a maintainence burden in the future this also leads to suboptimal code: The above code reads all three pointers (buf, buf_ptr and buf_end), but touching buf is unnecessary and switching to put_bytes_left() automatically fixes this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rationale is that coded_frame was only used to communicate key_frame, pict_type and quality to the caller, as well as a few other random fields, in a non predictable, let alone consistent way. There was agreement that there was no use case for coded_frame, as it is a full-sized AVFrame container used for just 2-3 int-sized properties, which shouldn't even belong into the AVCodecContext in the first place. The appropriate AVPacket flag can be used instead of key_frame, while quality is exported with the new AVPacketSideData quality factor. There is no replacement for the other fields as they were unreliable, mishandled or just not used at all. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| * Gather all coded_frame allocations and free functions to a single placeVittorio Giovara2015-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
