* avfilter/ccfifo: remove unnecessary context allocationsJames Almer2023-05-121-1/+1
| | | | | | | This is not public API, no it has no need for an alloc() and free() functions. The struct can reside on stack. Signed-off-by: James Almer <jamrial@gmail.com>
* avfilter/tinterlace: Properly preserve CEA-708 closed captionsDevin Heitmueller2023-05-111-0/+2
| | | | | | | | | | | | | | | Because the interlacing filter halves the effective framerate, we need to ensure that no CEA-708 data is lost as frames are merged. Make use of the new ccfifo mechanism to ensure that caption data is properly preserved as frames pass through the filter. Thanks to Thomas Mundt for review and noticing a couple of missed codepaths for injection on output. Thanks to Lance Wang for pointing out a memory leak.

* avfilter/vf_tinterlace: support full-range YUVNiklas Haas2022-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | This filter, when used in the "pad" mode, currently makes the distinction between limited and full range solely by testing for YUVJ pixel formats at link setup time. This is deprecated and should be improved to perform the detection based on the per-frame metadata. In order to make this distinction based on color range metadata, which is only known at the time of filtering frames, for simplicity, we simply allocate two copies of the "black" frame - one for limited range and the other for full range metadata. This could be done more dynamically (e.g. as-needed or simply by blitting the appropriate pixel value directly), but this change is relatively simple and preserves the structure of the existing code. This commit actually fixes a bug in FATE - the new output is correct for the first time. The previous md5 ref was of a frame that incorrectly combined full-range pixel data with limited-range black fields. The corresponding result has been updated.

* avfilter/vf_interlace: restore lowpass mode constantsMarton Balint2019-12-141-0/+7
| | | | | | | | 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>
