Nicolas George	2f76476549	lavfi: regroup formats lists in a single structure. It will allow to refernce it as a whole without clunky macros. Most of the changes have been automatically made with sed: sed -i ' s/-> in_formats/->incfg.formats/g; s/-> out_formats/->outcfg.formats/g; s/-> in_channel_layouts/->incfg.channel_layouts/g; s/-> out_channel_layouts/->outcfg.channel_layouts/g; s/-> in_samplerates/->incfg.samplerates/g; s/-> out_samplerates/->outcfg.samplerates/g; ' src/libavfilter/*(.)	4 years ago
Andreas Rheinhardt	97b1a2c564	avfilter/af_aiir: Fix segfault and leak upon allocation failure The aiir filter adds output pads in its init function. Each of these output pads had a name which was allocated and to be freed in the uninit function. Given that the aiir filter has between one and two outputs, one output pad's name was freed unconditionally and a second was freed conditionally. Yet if adding output pads fails, there are no output pads at all and trying to free a nonexistent pad's name will lead to a segfault. Furthermore, if the name could be successfully allocated, yet adding the new pad fails, the name would leak. This commit fixes this by not allocating the pads' names at all any more: They are constant anyway. This allows to remove the code to free them and hence fixes the aforementioned bugs.
