+.B zrmjpeg[=options]
+Software YV12 to MJPEG encoder for use with the zr2 video
+output device.
+Multiple options can be specified separated by ':'.
+.RSs
+.IPs maxheight=h|maxwidth=w
+These options set the maximum width and height the zr card
+can handle. (the MPlayer filter layer currently can't query those)
+.IPs {dc10+,dc10,buz,lml33}-{PAL|NTSC}
+Use these options to set maxwidth and maxheight automatically to the 
+values known for card/mode combo. For example, valid options are:
+dc10-PAL and buz-NTSC. The default is dc10+PAL.
+.IPs color|bw
+Select color or black and white encoding. Black and white encoding is 
+faster. Color is the default.
+.IPs hdec={1,2,4}
+Horizontal decimation 1, 2 or 4.
+.IPs vdec={1,2,4}
+Vertical decimation 1, 2 or 4.
+.IPs quality=1-20
+Set JPEG compression quality [BEST] 1 - 20 [VERY BAD]
+.IPs fd|nofd
+By default, decimation is only performed if the zoran hardware
+can upscale the resulting MJPEG images to the original size. The option
+fd instructs the filter to always perform the requested decimation (ugly).
