@end table
@item mjpeg_vaapi
Always encodes using the standard quantisation and huffman tables -
@option{global_quality} scales the standard quantisation table (range 1-100).
Only baseline DCT encoding is supported. The encoder always uses the standard
quantisation and huffman tables - @option{global_quality} scales the standard
quantisation table (range 1-100).
For YUV, 4:2:0, 4:2:2 and 4:4:4 subsampling modes are supported. RGB is also
supported, and will create an RGB JPEG.
@table @option
@item jfif
Include JFIF header in each frame (not included by default).
@item huffman
Include standard huffman tables (on by default). Turning this off will save
a few hundred bytes in each output frame, but may lose compatibility with some
JPEG decoders which don't fully handle MJPEG.
@end table
@item mpeg2_vaapi
@option{profile} and @option{level} set the value of @emph{profile_and_level_indication}.
