* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

* avcodec/g2meet: Fix undefined NULL + 0Andreas Rheinhardt2021-04-01
| | | | | | Affected the g2m4 FATE-test. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/g2meet, mjpegdec: Factor out common VLC initialization codeAndreas Rheinhardt2021-02-23
| | | | | | | | | While just at it, remove the nb_codes parameter: It is redundant (the number of codes is implicitly contained in the array containing how many entries of a specific size there are) and for this reason it might even be wrong, so it is better to check what is actually used instead.

* lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bumpAnton Khirnov2021-01-01
| | | | They are not properly namespaced and not intended for public use.
* avcodec/g2meet: Use least max_depth in get_vlc2()Andreas Rheinhardt2020-11-24
| | | | | | | | The longest AC codes of the standard JPEG tables are 16 bits long; for the DC tables, the maximum is 11, so using max_depth of two is sufficient. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/g2meet: Check tile_width in epic_jb_decode_tile()Michael Niedermayer2020-05-10
| | | | | | | | | | Fixes: out of array access Fixes: 21469/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_G2M_fuzzer-5199357982015488 Alternatively the arrays can be made bigger or the index can be clipped.

| | | | | | | | Fixes: Timeout (100sec -> 0.7sec) Fixes: 8668/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_G2M_fuzzer-5174143888130048 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avcodec/g2meet: Check if adjusted pixel was on the stackMichael Niedermayer2019-10-02
| | | | | | | | | | | | | This basically checks if a pixel that was coded with prediction and residual could have been stored using a previous case. This avoids basically a string of 0 symbols stored in less than 50 bytes to hit a O(n²) codepath. Fixes: Timeout (too slow to wait -> immediately) Fixes: 8668/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_G2M_fuzzer-4895946310680576 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
