* avcodec/msmpeg4: Factor out common RLTable initialization codeAndreas Rheinhardt2021-04-27
| | | | | | | | | | | | | Up until now, both the msmpeg4 decoders and encoders initialized several RLTables common to them (the decoders also initialized the VLCs of these RLTables). This is an obstacle to making these codecs init-threadsafe. So move this initialization to ff_msmpeg4_common_init() that already contains this initialization code. This allows to reuse the AVOnce used for initializing ff_v2_dc_lum/chroma_table which automatically makes initializing these RLTables thread-safe.

* 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/ituh263enc: Make static initializations thread-safeAndreas Rheinhardt2021-04-27
| | | | | | | | | | | | This already makes several encoders (namely FLV, H.263, H.263+ and RealVideo 1.0 and 2.0 and SVQ1) that use this init-threadsafe. It also makes the Snow encoder init-threadsafe; it was already marked as such since commit d49210788b0836d56dd872d517fe73f83b080101, because it was thought to be harmless if one and the same object was initialized by multiple threads at the same time.

* avcodec/encode: Zero padding in ff_get_encode_buffer()Andreas Rheinhardt2021-04-27
| | | | | | | | | | | | | The documentation of the get_encode_buffer() callback does not require to zero the padding; therefore we do it in ff_get_encode_buffer(). This also constitutes an implicit check for whether the buffer is actually allocated with padding. The memset in avcodec_default_get_encode_buffer() is now redundant and has been removed.

* avcodec/mjpegdec: postpone calling ff_get_buffer() until the SOS markerJames Almer2021-04-25
| | | | | | | | | | | | | | | With JPEG-LS PAL8 samples, the JPEG-LS extension parameters signaled with the LSE marker show up after SOF but before SOS. For those, the pixel format chosen by get_format() in SOF is GRAY8, and then replaced by PAL8 in LSE. This has not been an issue given both pixel formats allocate the second data plane for the palette, but after the upcoming soname bump, GRAY8 will no longer do that. This will result in segfauls when ff_jpegls_decode_lse() attempts to write the palette on a buffer originally allocated as a GRAY8 one. Work around this by calling ff_get_buffer() after the actual pixel format is known. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/jpeglsdec: Don't presume the context to contain a JLSStateAndreas Rheinhardt2021-04-20
| | | | | | | | | | | | | | | Before 9b3c46a081a9f01559082bf7a154fc6be1e06c18 every call to ff_jpegls_decode_picture() allocated and freed a JLSState. This commit instead put said structure into the context of the JPEG-LS decoder to avoid said allocation. But said function can also be called from other MJPEG-based decoders and their contexts doesn't contain said structure, leading to segfaults. This commit fixes this: The JLSState is now allocated on the first call to ff_jpegls_decode_picture() and stored in the context.

* avcodec/nvenc: fix lossless tuning logicTimo Rothenpieler2021-04-18
| | | | | | | | | | | | Relying on the order of the enum is bad. It clashes with the new presets having to sit at the end of the list, so that they can be properly filtered out by the options parser on builds with older SDKs. So this refactors nvenc.c to instead rely on the internal NVENC_LOSSLESS flag. For this, the preset mapping has to happen much earlier, so it's moved from nvenc_setup_encoder to nvenc_setup_device and thus runs before the device capability check.
