need to build an application around it but will allow you to multiplex different \
inputs over time. You can switch the active sink pad from a buffer probe at the src \
so that it all happens automatically.<br /> <br />

Hi<br />
<br />
I'm trying to make a command for creating a file from multiple H.264 files and the \
resulting file should contain a frame from each file in sequence. For instance, given \
N files, the resulting file should the sequence [VID1_frame1, VID2_frame1, … \
VIDN_frame1, VID1_frame2, VID2_frame2,… VIDN_frame2,… VIDN_frameM]. I believe \
it's not something compositor can handle because it doesn't seem to be able to \
provide a feed in sequence. I'm also hoping to use just one instance of videoconvert \
in the pipeline. Does anyone know how this can be achieved? Would I need to write a \
new type of queue?<br /> <br />
Any advice appreciated.<br />
<br />
