Antonio Ospite	d3958ab4ed	x11grab: fix a memory leak exposed by valgrind When using "-f x11grab -i :0.0" valgrind reports a definitely lost memory block with this message: ==31544== 5 bytes in 1 blocks are definitely lost in loss record 1 of 2 ==31544== at 0x4026E68: memalign (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==31544== by 0x4026F17: posix_memalign (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==31544== by 0x60D399A: av_malloc (in /usr/lib/x86_64-linux-gnu/libavutil.so.51.22.1) ==31544== by 0x60D3A70: av_strdup (in /usr/lib/x86_64-linux-gnu/libavutil.so.51.22.1) ==31544== by 0x4A2BE58: ??? (in /usr/lib/x86_64-linux-gnu/libavdevice.so.53.2.0) ==31544== by 0x506D29E: avformat_open_input (in /usr/lib/x86_64-linux-gnu/libavformat.so.53.21.0) ==31544== by 0x400A80: main (in /home/ao2/WIP/am7xxx-play/tests/a.out) The 5 bytes lost are the ones from param = av_strdup(":0.0"), so let's free param in the exit path. Also check the av_strdup() return value. Note: calling av_free(param) even when av_strdup() fails and param is NULL is OK and keeps the code simpler without adding another label to skip av_free().

Nicolas George	456d65a5c6	alsa: fix timefilter usage. The period argument is supposed to be the number of samples since the last update.	13 years ago
Nicolas George	9bbe6ed1e0	timefilter: allow variable periods. Initially found and designed by Michael Niedermayer.	13 years ago
Nicolas George	3073aadf2d	timefilter: internally compute feedback factors. The feedback factors for the timefilter are directly computed from the expected period. This commit changes the init function to accept the period itself and compute the feedback factors internally, rather than having all client code duplicate the formulas. This commit also actually fixes the formulas: the current code had sqrt(2o), but the correct formula, both theoretically and according to experimental testing, is sqrt(2)o. Furthermore, it adds an exponential to feedback factors larger than 1 with large periods.	13 years ago
