C++ Middleware Writer VS lossless-cut

I use unique_ptr, but not as much as I used to. I've never used shared_ptr. This is my library that uses some C++ 2020 and 2017 features.

I started with Linux in the late 90s. I switched to FreeBSD around 2013 and returned to Linux a couple of years ago. Io_uring was the main reason I had to come back. At first I ported the back tier of my code generator back to Linux and then I ported the middle tier from being POSIX based to Linux.

Are there others that minimize multithreading and opt for multi-processing with single threaded processes? Call me a simpleton, but this approach eliminates some of the most difficult bugs by design. Here's an example of one of my single-threaded servers. The network io is asynchronous, but the file io is synchronous. Thanks

I've been working on this program for 13 years now. At one point it had 7 global variables and none of them were const. Now it has 4 global variables and 2 of them are const.

in one of my programs. I'm thinking about changing it to:

It's a merger of services and code generation: an on-line code generator that outputs low-level messaging and serialization code based on high-level input. It's implemented as a 3-tier system and uses output from the code generator in each tier. There's also a traditional library that's part of the repo.

Support for more data types for message lengths. Previously message lengths were always 4 bytes. I used this, for example, to reduce the size of the type used for message lengths between the front and middle tiers of the CMW from 4 bytes to 2 bytes.

More concretely, I use it to generate code that's used in each of the tiers mentioned above. The link is to one example of that.

For lossless cut, there's the LosslessCut [1] app, which even has an experimental but mostly working version of a "smart cut" feature [2] (aka. only re-encode the minimal mandatory amount of frames if you trim at a point between 2 key frames)

> thought I cropped/edited a video, it is still there in full length and resolution

It's been possible to create a clip from a video file that merely changes what parts of the video are displayed without effecting the data in the original since the Classic Mac OS days.

If you want to completely remove unwanted portions of a video to reduce the size without a loss of quality, there are many options. LosslessCut is one option that is both free and open source.

LosslessCut

Lossless Cut is probably the simplest way to cut out parts of a video without having to re-encode it or use an online service. It is open source, free and available for all platforms. It is in essence a frontend for FFMPEG and cuts without re-encoding, so the results are instantaneous.

Additionally I would like if possible to shorten (both to reduce dimension and to make them less boring) my videos by trimming the beginning and/or ends where often there is nothing interesting happening and possibly change the thumbnails for easier identification. Do you know of any tool that does the job with the minimum quality degradation possible? Many years ago I've tried with some videos and a tool I don't remember anymore, ending up with a bunch of corrupted files :( I've found https://github.com/mifi/lossless-cut for the point above.. need to try it. please let me know what experience you have with it.

Lossless Cut would probably be a better choice for this. Will let you cut out the commercials without having to re-encode the video.

>Of course, you could only re-encode only the GoPs that get broken while keeping the rest intact, and I guess this would be better and a lot faster than re-encoding everything. I don't know if any application tries to do this.

LosslessCut does have experimental support for this partial re-encode called "smart cut" [1]. Since it's using ffmpeg internally, the challenge become how to instruct ffmpeg to do this[2]?
