* avcodec/on2avc: Use least max_depth for get_vlc2()Andreas Rheinhardt2020-10-21
| | | | | | | | The longest codes of any VLC codebooks are 18 bits long and the VLC tables itself use 9 bits; therefore it is sufficient to read twice from the table, yet this has been done thrice. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/on2avc: Unify initializing quad and pair VLCsAndreas Rheinhardt2020-10-21
| | | | | | | | | | | | 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.

* avcodec/vp3: Fix memleak upon init failureAndreas Rheinhardt2020-10-21
| | | | | | | | | | Up until now, there was no cleanup in case initializing the Theora VLC tables failed, leading to memleaks. This commit gets rid of them by setting the FF_CODEC_CAP_INIT_CLEANUP flag for all decoders in vp3.c; this also allows to remove some (now redundant) cleanup code.
