* avfilter/avfiltergraph: Simplify adding filter to graphAndreas Rheinhardt2021-10-02
| | | | | | | | | | By reallocating the array of pointers to the AVFilterContexts before allocating the new AVFilterContext one can avoid freeing the new AVFilterContext in case the array could not be reallocated. Also switch to av_realloc_array() while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* checkasm/hevc_pel: Fix stack buffer overreadsAndreas Rheinhardt2021-09-29
| | | | | | | | | | | | | This patch increases several stack buffers in order to fix stack-buffer-overflows (e.g. in put_hevc_qpel_uni_hv_9 in line 814 of hevcdsp_template.c) detected with ASAN in the hevc_pel checkasm test. The buffers are increased by the minimal amount necessary in order not to mask potential future bugs.

* avutil/utils: Remove racy check from avutil_version()Andreas Rheinhardt2021-09-29
| | | | | | | | | | | | | | | | avutil_version() currently performs several checks before just returning the version. There is a static int that aims to ensure that these tests are run only once. The reason is that there used to be a slightly expensive check, but it has been removed in 92e3a6fdac73f7e1d69d69717219a7538877d7a0. Today running only once is unnecessary and can be counterproductive: GCC 10 optimizes all the actual checks away, but the checks_done variable and the code setting it has been kept. Given that this check is inherently racy (it uses non-atomic variables), it is best to just remove it.

* avcodec/encode: Set AV_PKT_FLAG_KEY based upon AV_CODEC_PROP_INTRA_ONLYAndreas Rheinhardt2021-09-28
| | | | | | | | | | | Currently, the AV_PKT_FLAG_KEY is automatically set for audio encoders; yet this is wrong, as both MLP and TrueHD have non-keyframes. So set it based upon AV_CODEC_PROP_INTRA_ONLY (from the corresponding AVCodecDescriptor) instead. This also sets it for some video codecs, which is intended.

| | | | | | | | | | TrueHD/MLP is one of the audio formats with keyframes.
