* avcodec: add AV_PKT_DATA_AFD to allow AFD data to be embedded in AVPacketDevin Heitmueller2018-09-09
| | | | | | | | | | Create a new AVPacket side data type for Active Format Description, which mirrors the side data type found in AVFrame. The primary use case for this is ensuring AFD gets preserved in the V210 encoder, so that the decklink libavdevice can output AFD.

* lavc: implement an ATRAC9 decoderRostislav Pehlivanov2018-07-03
| | | | | | | | | | | | | | | | | | | | This commit implements a full ATRAC9 decoder, a simple low-delay codec developed by Sony and used in most PSVita games, some PS3 games and some PS4 games. Its similar to AAC in that it uses Huffman coded scalefactors but instead of vector quantization it just Huffman codes the spectral coefficients (in a way similar to how Opus splits band energy coding into coarse and fine precision). It opts to write rather large Huffman codes by packing several small coefficients into one Huffman coded symbol, though I don't believe this increases efficiency at all. Band extension implements SBC in a simple way, first it mirrors the lower spectrum onto the higher frequencies and then it uses one of 5 filters to shape it. Noise substitution is implemented via 2 of them. Unlike previous ATRAC codecs, there's no QMF, this is a standard MDCT codec. Based off of the reverse engineering work of Alex Barney.

* | avcodec: add a subcharenc mode that disables UTF-8 checkwm42018-03-25
| | | | | | | | | | | | | | | | This is for applications which want to explicitly check for invalid UTF-8 manually, and take actions that are better than dropping invalid subtitles silently. (It's pretty much silent because sporadic avcodec error messages are so common that you can't reasonably display them in a prominent and meaningful way in a application GUI.)

| * lavc: Add support for increasing hardware frame pool sizesMark Thompson2018-02-11
| | | | | | | | | | | | | | | | | | | | AVCodecContext.extra_hw_frames is added to the size of hardware frame pools created by libavcodec for APIs which require fixed-size pools. This allows the user to keep references to a greater number of frames after decode, which may be necessary for some use-cases. It is also added to the initial_pool_size value returned by avcodec_get_hw_frames_parameters() if a fixed-size pool is required.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the dependency that hardware pixel formats previously had on AVHWAccel instances, meaning only those which actually do something need exist after this patch. Also updates avcodec_default_get_format() to be able to choose hardware formats if either a matching device has been supplied or no additional external configuration is required, and avcodec_get_hw_frames_parameters() to use the hardware config rather than searching the old hwaccel list. The FF_CODEC_CAP_HWACCEL_REQUIRE_CLASS mechanism is deleted because it no longer does anything (the codec already contains the pointers to the matching hwaccels).

| * lavc: external hardware frame pool initializationwm42017-10-19
| | | | | | | | | | | | | | | | | | | | | | | | This adds a new API, which allows the API user to query the required AVHWFramesContext parameters. This also reduces code duplication across the hwaccels by introducing ff_decode_get_hw_frames_ctx(), which uses the new API function. It takes care of initializing the hw_frames_ctx if needed, and does additional error handling and API usage checking. Support for VDA and Cuvid missing.

* | avcodec: allow multiple hwaccels for the same codec/pixfmtwm42017-11-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVHWAccels are looked up using a (codec_id, pixfmt) tuple. This means it's impossible to have 2 decoders for the same codec and using the same opaque hardware pixel format. This breaks merging Libav's CUVID hwaccel. FFmpeg has its own CUVID support, but it's a full stream decoder, using NVIDIA's codec parser. The Libav one is a true hwaccel, which is based on the builtin software decoders. Fix this by introducing another field to disambiguate AVHWAccels, and use it for our CUVID decoders. FF_CODEC_CAP_HWACCEL_REQUIRE_CLASS makes this mechanism backwards compatible and optional.
