* lavf/flvdec: normalize exporting date metadataAnton Khirnov2021-05-12
| | | | | | | | | | | | | Export them in UTC, not the local timezone. This way the output is the same everywhere. The timezone information stored in the file is still ignored, since there seems to be no simple way to export it correctly. Format them according to ISO 8601, which we generally use for exporting dates. Fixes fate-flv-demux, which was broken since 958bea5248f87116b0dd080461aa70c14ea86cf0 on some platforms.

* avcodec/jpeg2000dec: Make decoder init-threadsafeAndreas Rheinhardt2021-05-12
| | | | | | | | | | | | | | | The JPEG-2000 decoder and encoder share common luts; the decoder initializes them once, guarded by a dedicated AVOnce, whereas the encoder initializes them always during init. This means that the decoder is not init-threadsafe; in fact there is a potential data race because these luts can be initialized while an active decoder/encoder is using them. Fix this and make the decoder init-threadsafe by making the initialization function guard initialization itself with a dedicated AVOnce.

* avcodec/mqc: Hardcode tables to save spaceAndreas Rheinhardt2021-05-12
| | | | | | | | | | | | | | | | | | mqc currently initializes three arrays at runtime; each of them has 2 * 47 elements, one is uint16_t, two are uint8_t, so that their combined size is 8 * 47. The source data for these initializations is contained in an array of 47 elements of size six. Said array is only used in order to initialize the other arrays, so the savings are just 2 * 47B. Yet this is dwarfed by the size of the code for performing the initializations: It is 109B (GCC 10.2, x64, -O3 albeit in an av_cold function); this does not even include the size of the code in the callers. So just hardcode these tables. This also fixes a data race, because the encoder always initialized these tables during init, although they might already be used at the same time by already running encoder/decoder instances.

* avcodec/vorbisenc: Combine codebooks, avoid relocationsAndreas Rheinhardt2021-05-12
| | | | | | | | | | | | | | | | | | | | The Vorbis encoder has an array of a structure containing all the ingredients for a codebook; this includes a pointer to the actual codebook and some even have a pointer to an array containing quant values. Each of these real codebooks is an array of its own. These pointers lead to relocations and therefore the array will be placed in .data.rel.ro and not in .rodata. This commit avoids the pointers altogether by combining all the actual codebooks into one big array; the actual codebooks are now accessed consecutively by incrementing the pointer used to access them by the length of the actual codebook that has just been dealt with (said length is contained in the structure describing the codebook). There is no downside to this given that these codebooks are already only used once during init. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/vorbisenc: Don't free uninitialized pointersAndreas Rheinhardt2021-05-12
| | | | | | | | | | | | | The Vorbis encoder allocates several arrays destined to contain pointers to separately allocated arrays; yet these arrays are allocated without initializing them: They are uninitialized until their final values are stored in them; so if allocating one of the earlier subarrays fails, all of the remaining pointers to subarrays are still uninitialized. But they are used for freeing, resulting in crashes. Fix this by zero-initializing the arrays with subarrays. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
