I made a parser crate called exifsd that can detect when you have a whole JPEG file. This will output a series of jpegs directly to its stdout. This might sound a bit dumb, but you could use -f image2pipe. If you are interested in collaborating, here is an invite to the Rust Photogrammetry Discord server. I am really interested in your crate as I was looking for something exactly like what it is doing.

I have done a lot of piping ffmpeg output around with Rust, but I haven't used the raw output yet. What's going on with the six repeated frames and junk in the middle? I assume this is a problem with the frames that my codec is emitting (sized incorrectly), but I feel like my math/approach should be right.Įdit: This is now solved and functional code is on the master branch.

jpg file extension the frames are in color. Why is the frame greyscale? I'd imagine that this is an ffmpeg configuration problem, but if I use the same command and output to disk with a. The crate code can be viewed here and is working to a degree, but outputs frames like this from this input video. I've hit a bit of a wall here and am hoping that someone more knowledgable about async Rust/ffmpeg can point me in the right direction. I got some great feedback there and decided to expand my async Rust knowledge by trying to skip the step of outputting frames to disk before reading them in again and instead piping ffmpeg to stdout and reading the frames directly.

A while ago I posted about my first Rust project, a crate that takes in an input video and outputs movie barcodes by getting the average color of each frame and compressing them into one image.
