* avformat/cafenc: Don't segfault upon allocation errorAndreas Rheinhardt2021-09-271-13/+10
| | | | | | | | | | | | | | | | | | | If an array for the packet sizes could not be successfully reallocated when writing a packet, the CAF muxer frees said array, but does not reset the number of valid bytes. As a result, when the trailer is written later, avio_write tries to read that many bytes from NULL, which segfaults. Fix this by not freeing the array in case of error; also, postpone writing the packet data after having successfully (re)allocated the array, so that even on allocation error the file can be correctly finalized. Also remove an unnecessary resetting of the number of size entries used at the end. Reviewed-by: Paul B Mahol <[email protected]> Signed-off-by: Andreas Rheinhardt <[email protected]>

* avcodec/avcodec: Make sanity check stricterAndreas Rheinhardt2021-09-261-2/+1
| | | | | | | | | | | | | If an AVCodec has a private class, its priv_data_size must be > 0 and at the end of a successful call to avcodec_open2() the AVCodecContext's priv_data must exist and its first element must be a pointer to said AVClass. This should not be conditional on priv_data_size being > 0 (which is tested by FATE) or on the private context having been successfully allocated (which has to have happened at that point). So remove these preconditions to make the test stricter. Signed-off-by: Andreas Rheinhardt <[email protected]>

* avfilter/formats: Avoid reallocations for video in ff_all_formats()Andreas Rheinhardt2021-09-261-5/+1
| | | | | | | | | | | | | Up until now, the list of pixfmts is reallocated every time an entry is added to it; there are currently 196 pixel formats, so this matters: It causes 5541704 calls to av_realloc_array() in a typical FATE run, which is the majority for said function (8095768 calls) and even a large chunk of the calls to av_realloc() itself (12589508 calls). Fix this by using ff_formats_pixdesc_filter() instead. Reviewed-by: Nicolas George <[email protected]> Signed-off-by: Andreas Rheinhardt <[email protected]>
* avfilter/formats: Make ff_formats_pixdesc_filter return AVFilterFormats*Andreas Rheinhardt2021-09-2614-106/+46
| | | | | | | | | | | | | | | | Up until now, it has returned the AVFilterFormats list via an AVFilterFormats** parameter; the actual return value was an int that was always AVERROR(ENOMEM) on error. The AVFilterFormats** argument was a pure output parameter which was only documented by naming the parameter rfmts. Yet nevertheless all callers initialized the underlying AVFilterFormats* to NULL. This commit changes this to return a pointer to AVFilterFormats directly. This is more in line with the API in general, as it allows to avoid checks for intermediate values.

* webp: fix transforms after a palette with pixel packing.Maryla2021-09-254-17/+29
| | | | | | | | | | | | | | | When a color indexing transform with 16 or fewer colors is used, WebP uses "pixel packing", i.e. storing several pixels in one byte, which virtually reduces the width of the image (see WebPContext's reduced_width field). This reduced_width should always be used when reading and applying subsequent transforms. Updated patch with added fate test.
