* avcodec/on2avc: Unify initializing quad and pair VLCsAndreas Rheinhardt2020-10-213-59/+40
| | | | | | | | | | | | Up until now, quad VLCs are initialized with codes of type uint32_t, pair VLCs with codes of type uint16_t. There were two separate loops in the decoder's init function for each type of VLC. This commit unifies this: The type of the codes are now passed in as void * and the actual size of the codes is obtained from a table. This approach also allows to use the smallest type for each VLC code table: some quad tables actually fitted in uint16_t. This allows to remove about 7KB from the binary.
