Re: [Motion-user] movie_passthrough- how does that interact with streams, encoding, etc

[Matt G. <mg...@gr...>]

I’m also interested in the movie_passthrough feature.

I believe the answer to Ted’s question below is high res capture does not use the movie_codec parameter.  That’s I think part of the idea - free the CPU from having to do the encoding of the higher res stream.  Instead the captured movie is created directly from the frames sent from the camera.

Disclaimer: just starting to learn this feature. Please correct/clarify as needed :)

Here is the documentation on the feature:
