 This source is mainly intended for a programmatic use, in particular
 through the interface defined in @file{libavfilter/vsrc_buffer.h}.
 
-It accepts the following parameters:
-@var{width}:@var{height}:@var{pix_fmt_string}:@var{timebase_num}:@var{timebase_den}:@var{sample_aspect_ratio_num}:@var{sample_aspect_ratio.den}
+This filter accepts the following parameters:
 
-All the parameters need to be explicitly defined.
+@table @option
 
-Follows the list of the accepted parameters.
+@item width
+Input video width.
 
-@table @option
+@item height
+Input video height.
 
-@item width, height
-Specify the width and height of the buffered video frames.
+@item pix_fmt
+Name of the input video pixel format.
 
-@item pix_fmt_string
-A string representing the pixel format of the buffered video frames.
-It may be a number corresponding to a pixel format, or a pixel format
-name.
+@item time_base
+The time base used for input timestamps.
 
-@item timebase_num, timebase_den
-Specify numerator and denomitor of the timebase assumed by the
-timestamps of the buffered frames.
+@item sar
+Sample (pixel) aspect ratio of the input video.
 
-@item sample_aspect_ratio.num, sample_aspect_ratio.den
-Specify numerator and denominator of the sample aspect ratio assumed
-by the video frames.
 @end table
 
 For example:
 @example
-buffer=320:240:yuv410p:1:24:1:1
+buffer=width=320:height=240:pix_fmt=yuv410p:time_base=1/24:sar=1
 @end example
 
 will instruct the source to accept video frames with size 320x240 and
 with format "yuv410p", assuming 1/24 as the timestamps timebase and
 square pixels (1:1 sample aspect ratio).
-Since the pixel format with name "yuv410p" corresponds to the number 6
-(check the enum AVPixelFormat definition in @file{libavutil/pixfmt.h}),
-this example corresponds to:
-@example
-buffer=320:240:6:1:24
-@end example
