Argh! I keep making mistakes. I'm working too quickly. You see, I had 2 differing versions: one
using 'telecine=pattern=5' and one using 'telecine=pattern=46'. They tried to do the same thing, but

I'm trying to stream to online service via FFmpeg. All my test commands works
fine with restream.io preview and with local rtmp server viewer. My OBS setup
works fine too (same resolution, server and key). Only when I'm about to start
ffmpeg stream from my command line it stucks after few

Why is FFMPEG use so much CPU vs native ALSA tools. For example I am able to
record using ALSA device and arecord at a sample rate of 96000 with no issues
and using very little CPU. But FFMPEG must be at 22050 to not get buffer xrun
errors and it uses 100% of one core of the PI.
Great tool

Yes. N.x, N.y, and N.z are lowercase so you won't get a match.
Apoligies for shouting to Carl and my sincerest thank you for the hints.
at one point i must've read a .c file with the positional elements that i

those. quite frustrated before i posted the first time.
there is a regex

thanks Paul B Maholfor such a concise and detailed answer with such exact

@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
-i input out.jpg ] and other layers such as [ A, N.x, P_world.G ] and each
attempt fails:
U:\> ffmpeg -layer G -i
You should never parse textual output of -h help.
If you need to get options of filter use library provided API.

is there a build step artifact that more cleanly has the self-doc

reverse engineer

Hello,
I'm trying to find info on the -layer flag for ffmpeg which seems to be
undocumented in terms of examples.
I have a sequence of multilayer EXRs that I'm trying to convert to JPEG and
from the sounds of it, I would be able to extract channels in the
multilayer EXR [e.g. R,G,B or Diffuse,
The input is a stream you’re reading at real time, the concept of frames as
when you decode a format that’s framed for network streaming doesn’t apply the
same.

True. Having multiple -f options on the output section of the ffmpeg sender
command line is unnecessary and has been adjusted since originally posted.
Only the last one takes effect, but doesn't trigger an error.
