[edit] Description
Checks if luma difference between lines are below or above given threshold and writes frame number in text file.
[edit] Requirements
- [x86/x64]: AviSynth 3.6 or greater is required in order to use this filter.
- Supported color formats: all planar YUV formats
[edit] Syntax and Parameters
- LinesLumaDiff (clip, string "output", int "left", int "top", int "right", int "bottom", float "tl", float "tt", float "tr", float "tb", bool "flush")
- clip =
- A clip to process. It must in YUV planar format.
- clip =
- string output =
- The path of the txt file with frames.
- string output =
- int left = 5
- int top = 5
- int right = 5
- int bottom = 5
- How many lines on each side will be checked.
- Set one (or more) of the sides to 0 to not process it.
- Must not be negative.
- int left = 5
- float tl = 0.14
- float tt = 0.14
- float tr = 0.14
- float tb = 0.14
- Threshold for each side.
- If the luma difference between the current and the neighbour line is above the threshold, frame property "LinesDiffLeft", "LinesDiffTop", "LinesDiffRight" or "LinesDiffBottom" with the difference is set. Optionally the frame number could be written in file by specifying "output".
- Must be between 0.0 and 1.0.
- float tl = 0.14
- bool flush = false
- True: The frame number is saved right after the difference is above the threshold.
- False: All frames with difference above the threshold are saved at once after the end of video.
- bool flush = false
[edit] Examples
Check the difference between the first and second row:
AviSource("Blah.avi") LinesLumaDiff(left=0, top=1, right=0, bottom=0) propShow() # if the difference is above the threshold there will be frame property "LinesDiffLeft"/"LinesDiffTop"/"LinesDiffRight"/"LinesDiffBottom"
[edit] Changelog
