Combine Ffmpeg commands into one single command (macOS)

[richiemcilroy]

Right now, there are two separate commands for capturing audio and video. They can be found in media.rs located in apps/desktop/src-tauri. I would like to have them combined into one single ffmpeg command to reduce system load when recording.

Requirements

• Create one single ffmpeg command that takes input from both the audio and video sources, muxing into one .ts file
  • This will probably be done by creating separate named pipes as the input sources
• Make sure the recording process is still performant after changing

@richiemcilroy
some example usage of the command?

[richiemcilroy]

@webbdays here's a link to where both of the separate commands are located;

https://github.com/CapSoftware/Cap/blob/main/apps/desktop/src-tauri/src/media.rs#L418

[webbdays]

yes, i would like to have idea of using command with both type of inputs.

[richiemcilroy]

@webbdays it's possible but requires the use of fifo named pipes so that ffmpeg can read from the two input sources from one command.

Or if there's an alternative method with a better approach that can also be used.

[webbdays]

ok.

[webbdays]

Currently, i am not full-fledged working on this.
others with ideas can attempt this issue.

Make sure the recording process is still performant after changing

do we have any sort of benchmark to run before and after?

[richiemcilroy]

I guess the benchmark is just making sure that the screen capture and microphone recording is being created from a single ffmpeg command instead of two currently

[ologbonowiwi]

Where are recordings saved on the dev environment (without S3 enabled)?

Also, do I need a running mysql to run the app locally?
