* avcodec/jpegtables: remove duplicate luma and chroma quantization tablesPeter Ross2022-10-261-13/+0
| | | | | | Duplicates of the standard JPEG quantization tables were found in the AGM, MSS34(dsp), NUV and VP31 codecs. This patch elimates those duplicates, placing a single copy in jpegquanttables.c.

* avcodec/vp3: Use symbols table for VP3 motion vectorsAndreas Rheinhardt2020-12-081-35/+11
| | | | | | | | | | | | | Expressions like array[get_vlc2()] can be optimized by using a symbols table if the array is always the same for a given VLC. This requirement is fulfilled for the VLC used for VP3 motion vectors. The reason it hasn't been done before is probably that the array in this case contained entries in the range -31..31; but this is no problem with ff_init_vlc_from_lengths(): Just apply an offset of 31 to the symbols before storing them in the table used to initialize VP3 motion vectors and apply an offset of -31 when initializing the actual VLC.

* avcodec/vp3: Make tables used to initialize VLCs smallerAndreas Rheinhardt2020-12-081-2590/+487
| | | | | | | | | This is possible by switching to ff_init_vlc_from_lengths() because it allows to replace codes of type uint16_t by symbols of type uint8_t; in some cases (like here) it also allows to replace explicitly coded codes by implicitly coded symbols.

* avcodec/vp3: Apply VLC offset during initAndreas Rheinhardt2020-12-081-19/+5
| | | | | | | | | | By switching to ff_init_vlc_from_lengths() one can apply both positive as well as negative offsets for free; in this case it even saves space because one replaces codes tables that don't fit into an uint8_t by symbols tables that fit into an uint8_t or can even be completely avoided as they are trivial.

* vp3data: Make some arrays unsigned to prevent overflowAndreas Rheinhardt2019-07-241-3/+3
| | | | | | | | | | | | | Some of the VP3 arrays (namely vp31_intra_y_dequant, vp31_intra_c_dequant and vp31_inter_dequant) are currently declared as array of (const) int8_t despite them being only used to directly initialize an array of uint8_t. vp31_inter_dequant even contains the value 128 which is not representible in int8_t and might generate overflow warnings by compilers.
