@Gonzalo - Thanks for that feedback! With the channels listed in the
response I sent Carl, do you see any issues with the channel names? These
image sequences are coming from SideFX Houdini.
When a patch is created, where would I get that?
Thanks again Gonzalo!

@Carl - I did try multiple single channels at a time [ e.g. ffmpeg -layer G

attempt fails:
U:\> ffmpeg -layer G -i
Y:\projects\skyCity\locations\int1\opt1\008-ngt\fx\work\houdini\renders\SRain\shot08_Cam12\v003\skyCity_int1
You should never parse textual output of -h help.
If you need to get options of filter use library provided API.

Thanks Ted,
It's exactly what I'm doing. I'm rewriting the master playlist on the fly with
NGINX.
The strange thing is that audio_1 and so on are arbitrary names set by ffmpeg
by itself so I really don't understand if this is a expected behaviour or some

From looking at the source code, I can tell you that those NAMEs are

Hi Guys,
Does anybody know If there is a way to set a specific value of NAME in
