Jasper Taylor	0d5ae023b2	avfilter/vf_tinterlace: Fix vf_tinterlace mode 6 (interlacex2) 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.

Clément Bœsch	50e66726a2	lavfi: use ceil right shift for chroma width/height. This should fix several issues with odd dimensions inputs. lut, vflip, pad and crop video filters also need to be checked for such issues. It's possible sws is also affected.	12 years ago

Stefano Sabatini	fd5293d216	lavfi/tinterlace: set inlink->cur to NULL, since it is stored internally If not set to NULL, the reference is freed by ff_end_frame(), and later accessed in end_frame() by the filter code, causing a crash.	12 years ago

Stefano Sabatini	837d034787	lavfi/tinterlace: make video as interlaced in mode 6 This is useful for marking progressive video processed by the filter as interlaced, avoiding the interlaced flag to switch back and forth at each frame.	13 years ago
Stuart Morris	820c023142	lavfi/tinterlace: add tinterlace mode 6 This new mode is useful for generating frames for interlaced video displays. Typically interlaced video displays have no form of field synchronisation. This new mode guarantees correct field order without any requirement for field synchronisation.

Stefano Sabatini	8fb03b4d70	lavfi: port tinterlace filter from MPlayer Port MPlayer tinterlace filter from MPlayer, with some ideas taken from the FFmbc/libavfilter port, with the following main differences: * added support for full-scale YUVJ formats * added support for YUVA420P * request_frame() on the filter is forced to return a frame * some code factorization (related to the copy_picture_fields() function) * fixed black padding values for mode 3	14 years ago
