Public bug reported:
Binary package hint: ffmpeg
While using ffmpeg to transcode a movie captured on my iphone I needed
to uses the filter vflip and hflip, but ffmpeg -filters shows no filters
available, and ffmpeg doesn't recognize neither -vf "hflip,vflip" nor
-vfilters "hflip,vflip".
Expected results from ffmpeg -filters is something like
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.
