Michael Niedermayer	bc4e798562	avdevice/timefilter: 2nd try at avoiding rounding issues This hopefully fixes fate-timefilter Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	d6fd1242f3	avdevice/timefilter-test: provide more space for the printout to allow larger values Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	2b9590ebab	avdevice/timefilter-test: dont try to optimize par1 for n0=0 case for the n0=0 case there are multiple solutions and different platforms pick different ones This should reduce the issues with fate and the timefilter test Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	66487d73c3	avdevice/timefilter: cleanup the formating of the test output Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Nicolas George	8a9ae37fee	timefilter: allow to evaluate at other times.	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
Michael Niedermayer	a5bf9b351c	timefilter: better selftest code. Add support for divergence detection and variable period. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Anton Khirnov	5dd35b43f1	Move timefilter code from lavf to lavd. It's only used in the JACK device. Fixes linking shared lavd with JACK enabled.	13 years ago
Diego Biurrun	70ad9842a5	Fix compilation of timefilter test program. The printf function is forbidden in library code, but not in test programs, so #undefine the printf macro that disables the system printf function. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
