* avfilter/vf_interlace: do not interlace already interlaced framesMarton Balint2019-12-15

* avfilter/vf_interlace: restore lowpass mode constantsMarton Balint2019-12-14
| | | | | | | | The documentation still mentions numerical constants in addition to textual ones. It is also wrong to use distinct modes as flags and it disallows us to actually use the flags field for real flags in the future. Signed-off-by: Marton Balint <cus@passwd.hu>

* avfilter/interlace: prevent over-sharpening with the complex low-pass filterThomas Mundt2017-09-15
| | | | | | | | | | | | | | | | | The complex vertical low-pass filter slightly over-sharpens the picture. This becomes visible when several transcodings are cascaded and the error potentises, e.g. some generations of HD->SD SD->HD. To prevent this behaviour the destination pixel must not exceed the source pixel when the average of the pixels above and below is less than the source pixel. And the other way around. Tested and approved in a visual transcoding cascade test by video professionals. SSIM/PSNR test with the first generation of an HD->SD file as a reference against the 6th generation(3 x SD->HD HD->SD): Results without the patch: SSIM Y:0.956508 (13.615881) U:0.991601 (20.757750) V:0.993004 (21.551382) All:0.974405 (15.918463) PSNR y:31.838009 u:48.424280 v:48.962711 average:34.759466 min:31.699297 max:40.857847 Results with the patch: SSIM Y:0.970051 (15.236232) U:0.991883 (20.905857) V:0.993174 (21.658049) All:0.981290 (17.279202) PSNR y:34.412108 u:48.504454 v:48.969496 average:37.264644 min:34.310637 max:42.373392 Signed-off-by: Thomas Mundt <tmundt75@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* lavfi: split frame_count between input and output.Nicolas George2016-11-13
| | | | | | | | | | | | AVFilterLink.frame_count is supposed to count the number of frames that were passed on the link, but with min_samples, that number is not always the same for the source and destination filters. With the addition of a FIFO on the link, the difference will become more significant. Split the variable in two: frame_count_in counts the number of frames that entered the link, frame_count_out counts the number of frames that were sent to the destination filter.

* avfilter/vf_tinterlace: Fix vf_tinterlace mode 6 (interlacex2)Jasper Taylor2014-03-16
| | | | | | | | | | | | | | | | The purpose of this filter mode is to allow interlaced content to display properly in interlaced video modes, as described in http://forum.xbmc.org/showthread.php?tid=81834 and https://github.com/mpv-player/mpv/issues/624#issuecomment-37685195 . The filter doubles the video frame rate, but does not work properly because: (1) it does not set the properties of the output stream to indicate the doubled frame rate, and (2) it does not set an appropriate PTS on the extra frames. The attached patch fixes these problems by settling these values the same way they are set in vf_yadif mode 1 (field) which also doubles the frame rate.
