Martin Storsjö	6b9b42cc55	drawtext: Remove the ifdef for localtime_r If it isn't available in the system, we've got a fallback to the normal localtime function, so normal code can assume it is available as long as time_internal.h is included.

Neil Birkbeck	ad5c43bb36	avfilter/vf_idet: Fixes issue with idet not flushing last frame. Uses a similar approach as vf_yadif to flush the last frame in idet. Quick test with 50 frames from vsynth1: ./ffmpeg.old -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1 \| grep Multi (gives) [Parsed_idet_0 @ 0x261ebb0] Multi frame detection: TFF:0 BFF:0 Progressive:48 Undetermined:1 ./ffmpeg -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1 \| grep Multi (gives) [Parsed_idet_0 @ 0x35a0bb0] Multi frame detection: TFF:0 BFF:0 Progressive:49 Undetermined:1 Fate tests have been updated. (In testing, it seems this filter will also need a subsequent patch for single frame input) Signed-off-by: Neil Birkbeck <neil.birkbeck@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Timothy B. Terriberry	6cbbf0592f	resample: Avoid off-by-1 errors in PTS calcs. The rounding used in the PTS calculations in filter_frame() does not actually match the number of samples output by the resampler. This leads to off-by-1 errors in the timestamps indicating gaps and underruns, even when the input timestamps are all contiguous.
