Tsutomu Seki	9b445663a5	avfilter/opencl: Fix program_opencl for source code larger than 64kB The condition (pos < len) is always true and the rest of the OpenCL program code would not be read, while the maximum number of "rb" is "len - pos - 1", and then, the maximum number of the "pos" is "len - 1".

Andreas Rheinhardt	f626a3d0e0	Revert "avfilter/vf_idet: reduce noisyness if the filter has been auto inserted" This reverts commit `723c37d3b7`. Said commit was in preparation for auto-inserting the idet filter. This has never happened; even if it did, the code is wrong, because it segfaults if the filter instance doesn't have a name (having one is not mandatory). Furthermore, it is documented for libavfilter to not assign any semantics to the name, which this check violates. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago

Mark Reid	716b396740	avfilter/vf_lut3d: add x86-optimized tetrahedral interpolation I spotted an interesting pattern that I didn't see before that leads to the implementation being faster. The bit shifting table I was using before is no longer needed, and was able to remove quite a few lines.

Andreas Rheinhardt	0c0d5faf94	avfilter/asrc_flite: Remove double ';' (Inside a function a stray ';' is an empty statement; outside of a function it is actually invalid, but compilers happen to accept it without complaint (unless e.g. using -pedantic).)

Andreas Rheinhardt	aac8fa2fbf	avfilter/asrc_flite: Fix races upon (un)registering voices The voice registration system in libflite is broken: It is not thread-safe and also not based on internal counters; instead any call to unregister a voice frees said voice even if there are still many other users of said voice who have also registered said voice. While there is no way to guard against another library unregistering voices behind our back, we can at least be correct in the absence of other users of libflite. The current code already tried this by using a reference count of our own for each voice; but the implementation of this is not thread-safe at all. Fix this by using a mutex to guard all of libavfilter's libflite registration and unregistration calls, thereby being thread-safe in the absence of other libflite users.

Andreas Rheinhardt	18ddb25c7a	avfilter/asrc_flite: Fix use-after-frees When an flite filter instance is uninitialized and the refcount of the corresponding voice_entry reaches zero, the voice is unregistered, yet the voice_entry's pointer to the voice is not reset. (Whereas some other pointers are needlessly reset.) Because of this a new flite filter instance will believe said voice to already be registered, leading to use-after-frees. Fix this by resetting the right pointer instead of the wrong ones. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago

Andreas Rheinhardt	5e1dac380b	avfilter/avfiltergraph: Fix use-after-free when inserting auto-converter 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 `85a6404d7e`.
