6.3.2. Routing table fields
The following fields set up the routing table, where video- or mono audio input streams are mapped to
specific decoder output ports. For more details see the vstream and astream fields section above.
field name
field
type
value description since
vstream0 optional video elementary
stream index
number [0,...]
Links an input video elementary stream to the
decoder's video output port #0. Specifies the index
number for the first video elementary stream from
the imaginary stack of video streams supplied by
the sum of the input files. For normal clips this is
the video stream used for playout. For animations,
this is the stream used for the fill data. See the
section on vstream fields .
vstream1 optional video elementary
stream index
number [0,...]
Links an input video elementary stream to the
decoder's video output port #1. Specifies the
second video elementary stream, see vstream0
for details. This field is only needed for animations,
where vstream1 specifies the key (alpha
channel) data.
astream0 optional audio mono
channel index
number [0,...]
Links an input mono audio channel to the
decoder's mono audio output port #0. Specifies the
first input audio mono channel from the imaginary
stack of input mono channels supplied by the sum
of the input files. See the section on astream fields .
When neither the vstream0 nor astream0 fields
are defined, all of the video- and audio streams are
used.
astreamN optional audio mono
channel index
number
Links an input mono audio channel to the
decoder's mono audio output port #N. Specifies
the next input mono audio channel to be used for
output, where N is in the range [1-15]. See the
section on astream fields .
