:zap: Improve the performance of the `tui` app

[neon-mmd]

Work Expected From The Issue

Provide several optimizations to improve the performance of the video playback by making the following changes:

• Use an alternative allocator like mimalloc to improve the performance of the TUI app.
• Enable gzip, brotli and http dynamic window size features on the reqwest client to speed up downloads.
• Use rayon to parallalize coloring and drawing work of frames both of videos and images to speed up video playback performance dramatically.
• Make stdout buffered using BufWriter.
• Improve file reads using BufReader.
• Replace gifs & gifs-dispose crate with opencv as using the prior gives poor performance and causes occasional video stutters.
• Replace fast-image-resize code with image code which internally uses rayon by default.
• Provide more optimised release build and debug build profiles.

The issue expects the following files to be changed/modified:

• src/common/errors.rs
• src/main.rs
• src/pipeline/frames.rs
• src/pipeline/image_pipeline.rs
• src/pipeline/runner.rs
• src/terminal/mod.rs
• Cargo.toml

Note

All the files that are expected to be changed are located under the codebase (tplay directory).

Reason Behind These Changes

The reason behind having these changes is to improve the performance of the TUI app which can improve the performance of downloads and video playback, which can drastically improve the user experience.

@maxcurzi could you please assign this issue to me. Would love to work on this issue. 🙂

@neon-mmd I'm happy for you to have a go at it!

Please keep things as simple as possible and measure performance before/after each update 😉

@neon-mmd when you say "TUI app", do you mean there's work done to make tplay an app that can run within https://github.com/ratatui/ratatui ?
It would be cool

Yes sure, 100% I think it is a must like without that you might optimize code without gaining any benefits. 🙂

No, actually I didn't knew what should I call it in the issue. So that's why I called it a tui app but I think I can work on it like it would be cool thing to implement. 🙂

(Also, I have a few issues in mind which I will be opening soon like I found a replacement for opencv which I think could be great if we switch to it. As well as I am thinking to implement video preload cache like how we see on mpv or vlc where it loads and process the video ahead of time like I have an implementation in mind which will use queues. The only problem I face with video precache is that I will need to figure out how to implement a 5 seconds wait for the initiial cache load. Additionally, I will also open a feature request about looping support for the app. 🙂 )
