* lavc/get_bits: add a compat wrapper for the cached bitstream readerAnton Khirnov2023-01-06
| | | | Use that instead of the merged version.
* libavcodec/flacdec: Implement decoding of 32 bit-per-sample PCMMartijn van Beurden2022-12-26
| | | | Add decoding of FLAC files coding for 32 bit-per-sample PCM to libavcodec.
* get_bits: move check_marker() to mpegvideodec.hAnton Khirnov2022-07-04
| | | | | It is only used by mpegvideo-based decoders - specifically mpeg12, intelh263, ituh263, mpeg4video.
* avcodec/vlc: Use structure instead of VLC_TYPE array as VLC elementAndreas Rheinhardt2022-06-17
| | | | | | | | | | | | | | | | | | In C, qualifiers for arrays are broken: const VLC_TYPE (*foo)[2] is a pointer to an array of two const VLC_TYPE elements and unfortunately this is not compatible with a pointer to a const array of two VLC_TYPE, because the latter does not exist as array types are never qualified (the qualifier applies to the base type instead). This is the reason why get_vlc2() doesn't accept a const VLC table despite not modifying the table at all, as there is no automatic conversion from VLC_TYPE (*)[2] to const VLC_TYPE (*)[2]. Fix this by using a structure VLCElem for the VLC table. This also has the advantage of making it clear which element is which. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* lavc/get_bits: avoid avcodec.h dependencyAnton Khirnov2021-06-10

* avcodec: add Newtek SpeedHQ decoderSteinar H. Gunderson2017-01-11
| | | | | | | | | | | | | | This decoder can decode all existing SpeedHQ formats (SHQ0–5, 7, and 9), including correct decoding of the alpha channel. 1080p is decoded in 142 fps on one core of my i7-4600U (2.1 GHz Haswell), about evenly split between bitstream reader and IDCT. There is currently no attempt at slice or frame threading, even though the format trivially supports both. NewTek very helpfully provided a full set of SHQ samples, as well as source code for an SHQ2 encoder (not included) and assistance with understanding some details of the format.
