+
+Detiles the Framebuffer tile layout into a linear layout using CPU.
+
+It currently supports conversion from Intel legacy tile-x and tile-y as well
+as the newer Intel tile-yf layouts into a linear layout. This is useful if
+one is using kmsgrab and hwdownload to capture a screen which is using one
+of these non-linear layouts.
+
+NOTE: It also provides a generic detiling logic, which can be easily configured
+to detile many different tiling schemes if required, in future. The same is
+used for detiling the intel tile-yf layout. Also sample configuration to handle
+intel tile-x and tile-y using generic detile logic is also shown for reference,
+in the code.
+
+Currently it expects the data to be a 32bit RGB based pixel format. However
+the logic doesnt do any pixel format conversion or so. Later will be enabling
+16bit RGB data also, as the logic is transparent to it at one level.
+
+One could either insert this into the filter chain while capturing itself,
+or else, if it is slowing things down or so, then one could instead insert
+it into the filter chain during playback or transcoding or so.
+
+It supports the following optional parameters
+
+@table @option
+@item type
+Specify which detiling conversion to apply. The supported values are
+@table @var
+@item 0
+Dont do detiling.
+@item 1
+Auto detect detile logic to apply (supported in vf_hwdownload, not in vf_fbdetile).
+@item 2
+intel tile-x to linear conversion (the default).
+@item 3
+intel tile-y to linear conversion.
+@item 4
+intel tile-yf to linear conversion.
+@end table
+@end table
+
+If one wants to convert during capture itself, one could do
+@example
+ffmpeg -f kmsgrab -i - -vf "hwdownload,format=bgr0,fbdetile" OUTPUT
+@end example
+
+However if one wants to convert after the tiled data has been already captured
+@example
+ffmpeg -i INPUT -vf "fbdetile" OUTPUT
+@end example
+@example
+ffplay -i INPUT -vf "fbdetile"
+@end example
+
+NOTE: While transcoding a test 1080p h264 stream, with 276 frames, below was
+the average times taken by the different detile logics.
+@example
+rm out.mp4; time ./ffmpeg -i input.mp4 out.mp4
+rm out.mp4; time ./ffmpeg -i input.mp4 -vf fbdetile=2 out.mp4
+rm out.mp4; time ./ffmpeg -i input.mp4 -vf fbdetile=3 out.mp4
