ffmpeg-devel: Blackframe filter missing

[Liontooth (David Liontooth)]

In ffmpeg-devel 25102, ffmpeg -filters show

Filters:
anull            Pass the source unchanged to the output.
aspect           Set the frame aspect ratio.
crop             Crop the input video to x:y:width:height.
fifo             Buffer input images and send them when they are requested.
format           Convert the input video to one of the specified pixel formats.
hflip            Horizontally flip the input video.
noformat         Force libavfilter not to use any of the specified pixel formats for the input to the next filter.
null             Pass the source unchanged to the output.
pad              Pad input image to width:height[:x:y[:color]] (default x and y: 0, default color: black).
pixdesctest      Test pixel format definitions.
pixelaspect      Set the pixel aspect ratio.
scale            Scale the input video to width:height size and/or convert the image format.
slicify          Pass the images of input video on to next video filter as multiple slices.
unsharp          Sharpen or blur the input video.
vflip            Flip the input video vertically.
buffer           Buffer video frames, and make them accessible to the filterchain.
color            Provide an uniformly colored input, syntax is: [color[:size[:rate]]]
nullsrc          Null video source, never return images.
nullsink         Do absolutely nothing with the input video.

This leaves out a number of filters, such as:

blackframe       Detect frames that are (almost) black.

It looks like the source does not contain this filter (?), so I'm marking this a request for a more recent version. FFmpeg 0.7-rc1 was released on 2011-04-27 and has some very attractive features.

ffmpeg updated to version 0.7.4 in r83674 which includes the blackframe filter among others.
