* 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>

* avcodec/vc1: more corrections for AC inverse quantization scalingJerome Borsboom2018-04-25

| * lavc: deprecate the use of AVCodecContext.time_base for decodingAnton Khirnov2014-10-15
| | | | | | | | | | | | | | | | | | | | | | When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.
