* avcodec/mpeg12dec: Fix usage of init_get_bits() and use init_get_bits8()Limin Wang2021-10-091-1/+1

* configure: export pkg-config includedir variableJames Almer2021-10-091-1/+4
| | | | | | | | | | Some packages may not define custom cflags, in which case a simple "pkg-config --cflags" call will return an empty string. This change will be useful to get a valid include path that can be used in library checks. Reviewed-by: Haihao Xiang <haihao.xiang@intel.com> Signed-off-by: James Almer <jamrial@gmail.com>

* avdevice/xv: Increase array sizeAndreas Rheinhardt2021-10-091-1/+1
| | | | | | | | | | | | | av_image_copy() expects an array of four pointers according to its declaration; although it currently only touches pointers that are actually in use (depending upon the pixel format) this might change at any time (as has already happened for the linesizes in d7bc52bf456deba0f32d9fe5c288ec441f1ebef5). This fixes ticket #9264 as well as a warning from GCC 11. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avfilter/af_atilt: Constify filterAndreas Rheinhardt2021-10-091-1/+1
| | | | | | | | | (It is actually UB if a declaration and its definition differ wrt their types like they do in this case (the declaration in allfilters is const).) Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/allformats: Fix data race when accessing devices listsAndreas Rheinhardt2021-10-091-11/+11
| | | | | | | | | | | | | | | | | | Up until now setting the input and output devices lists is guarded by a mutex. This prevents data races emanating from multiple concurrent calls to avpriv_register_devices() (triggered by multiple concurrent calls to avdevice_register_all()). Yet reading the lists pointers was done without any lock and with nonatomic variables. This means that there are data races in case of concurrent calls to av_(de)muxer_iterate() and avdevice_register_all() (but only if the iteration in av_(de)muxer_iterate exhausts the non-device (de)muxers). This commit fixes this by putting said pointers into atomic objects. Due to the unavailability of _Atomic the object is an atomic_uintptr, leading to ugly casts. Switching to atomics also allowed to remove the mutex currently used in avpriv_register_devices(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avfilter/avfiltergraph: Fix use-after-free when inserting auto-converterAndreas Rheinhardt2021-10-081-6/+5
| | | | | | | | | | | | | | | | | | | | When inserting an auto-resampler, it may be that the configuration of the filters that the auto-resampler is supposed to connect is already partially merged, i.e. converter->inputs[0].incfg.foo and converter->outputs[0].outcfg.foo (where foo is one of formats, samplerates, channel_layouts) can coincide. Therefore merging the converter filter's input link might modify the outcfg of the converter' outlink. Yet the current code in avfiltergraph.c used pointers from before merging the inlink for merging the outlink, leading to a use-after-free in command lines like: $ ffmpeg -f lavfi -i anullsrc=cl=stereo -lavfi channelsplit,axcorrelate -f null - Fix this by not using outdated values when merging the outlink. This is a regression since 85a6404d7e6c759ddf71d6374812d7ff719728ec.
