* avfilter/vf_morpho: Fix invalid frees on errorAndreas Rheinhardt2021-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code used a pointer to an array (of arrays) that is offset relative to the start of the actually allocated buffer. Yet offsetting the pointer is only done on success, whereas the freeing code believes it to have happened even on error. So if any of the subarrays (or the subarrays' subarrays) can't be successfully allocated, one gets a bad free in free_lut(). Furthermore, said offsetting is only permissible in case the offsetted pointer points in the allocated buffer (here: in case the LUT's min_r is <= 0), as pointer arithmetic is undefined in case it exceeds the allocated object. Moreover, in case one of the subarrays couldn't be allocated, the code nevertheless tried to free the subarray's subarrays; and in case one of the subarray's subarrays could not be allocated successfully, there will be an invalid free, too, because the pointers for the subarrays' subarrays are also offset compared to the base pointer. This commit fixes all of this, by using the actually allocated pointer for freeing and by adding appropriate checks before freeing the subarrays. The former also allows to distinguish the cases in which the lut is currently only half-allocated due to an error in an earlier allocation attempt from the success case.

* avfilter/formats: Avoid reallocations for video in ff_all_formats()Andreas Rheinhardt2021-09-26
| | | | | | | | | | | | | 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 <george@nsup.org> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avfilter/formats: Make ff_formats_pixdesc_filter return AVFilterFormats*Andreas Rheinhardt2021-09-26
| | | | | | | | | | | | | | | | 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.
