where the files are scanned in the order specified. Note that non-audio streams are ignored.
For example, assume we have three input files. File0 provides a single video stream and two stereo
audio streams. File1 holds a single 4-channel audio stream. File2 holds a video stream and an 8-channel
audio stream. In total 4 + 4 + 8 mono audio input channels are available. The mono audio channel index
numbers then look like this:
• File0: index 0, 1 and 2, 3 for the four mono channels found in the two stereo audio streams.
• File1: index 4, 5, 6 and 7 for the four mono channels found in the 4-chan audio stream.
• File2: index 8, 9, ... 15 for the eight mono channels found in the 8-chan audio stream.
Now to connect the first two mono audio channels from the 8-chan audio elementary stream from File2 to
the first two audio output port of the decoder:
astream0=8; astream1=9;
Keep in mind that the astream0 and astream1 fields represent the decoder's mono audio output ports #0
and #1.
To combine the last mono audio channel from File0 and the second mono audio channel from File1 to
form a stereo decoder output:
astream0=3; astream1=5;
6.2.3. Single mono channel to several outputs
Note that it is possible to connect an input mono audio channel to several of the decoder's outputs, for
example to make a single mono channel into a stereo (dual mono) channel:
astream0=4; astream1=4;
However, it is not possible to mix two input mono audio channels into a single decoder mono output port:
astream0=4; astream0=5; INVALID!!
