REDline piping data to ffmpeg

[Elliott Balsley]

Is this possible?

No replies, so I'm thinking this is probably impossible.
On the other hand, there is an active ticket in the FFmpeg feature request tracker to add R3D decoding support using the official SDK. If anyone else is interested in this, you can vote on the feature request at https://trac.ffmpeg.org/ticket/2690

What do you need to do in ffmpeg that Redline can't?

You could process the files with Redline and have ffmpeg watch a folder and do the other half of the process.

I'd like to encode with x264 because it's fast and much nicer than Apple's built-in H.264, which I think is what redline uses.
Other than that, I'm just fond of ffmpeg, and I think it would be really cool to add more format support so we have options. To make some intermediate format using redline is possible, but inefficient and probably slower than going all in one step.

Some theoretical uses off the top of my head:
concatenate a bunch of files for dailies
sync audio based on timecode
make a timelapse
grab frames in other still image formats
superimpose watermark image
extract audio only

It's unlikely that ffmpeg would ever be used for online finishing because REDline will always be ahead with the latest color science and metadata, but it could be a nice option for offline and dailies work.

I was trying to do this same thing a while back and could not get it to work. Hours and hours sunk lol. So if you find any clues please post it up
