Can I mux video from one file with audio from another? YES! We now have an mpeg-2 muxing feature that takes two source files and outputs a DVD format mpeg-2 file (PAL or NTSC)
Here's a snippet of the XML you would use:
<?xml version="1.0"?> <query> <action>AddMedia</action> <userid/> <userkey/> <source>[Video source]</source> <source>[Audio source]</source> <format> <output>muxer</output> <target>ntsc-dvd</target> <!-- or pal-dvd --> <maps>0:0,1:0</maps> </format> </query>
Unfortunately, we do not currently support muxing to mpeg-4 output. We also do not support start/duration flags for multiple sources during a concatenation encode, and have no plans to do so.
