* avcodec/mpeg4video: Skip unneeded element when parsing picture headerAndreas Rheinhardt2022-01-09
| | | | | | | | | | Namely, skip some elements that are only useful for a decoder when calling ff_mpeg4_decode_picture_header() from the MPEG-4 parser. In particular, this ensures that the VLCs need no longer be initialized by the parser. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpeg4video: Make initializing RLTable thread-safeAndreas Rheinhardt2021-04-27
| | | | | | | | | | | Up until now the RLTable ff_mpeg4_rl_intra was initialized by both mpeg4 decoder and encoder (except the VLCs that are only used by the decoder). This is an obstacle to making these codecs init-threadsafe, so move initializing this to a single function that is guarded by a dedicated AVOnce.

* avcodec/mpeg4video: Make tables used to initialize VLCs smallerAndreas Rheinhardt2020-12-08
| | | | | | | | | | Switching from ff_init_vlc_sparse() to ff_init_vlc_from_lengths() allows to replace codes which are so long that they need to be stored in an uint16_t by symbols which fit into an uint8_t; and even these can be avoided in case of the sprite trajectory VLC.

* avcodec/mpeg4videodec: Fix nonsense warningAndreas Rheinhardt2019-03-12
| | | | | | | | | | | | Since db772308941a2a338c7809f90d347219a6a93074 parsing of mpeg4-extradata lead to a "Failed to parse extradata" warning, because ff_mpeg4_decode_picture_header returns AVERROR_INVALIDDATA in case that no VOP was found. This patch adds a parameter to signify whether a header (where the absence of a VOP does not raise an error) or not is parsed. The first mode is of course used for parsing headers.
