Potential Improvements to OBS-MP

[crschindler]

Hello,

I made a list of improvements primarily for local recording but some of them would apply for streaming as well.

1. Support encoding using NVENC while preserving 4:4:4 (no chroma subsampling) for almost lossless capture
2. Implement Frame Buffer Capture (NVFBC) and Inband Frame Readback (NVIFR) for performance reasons
3. Allow lossless audio capture when using multiple audio tracks
4. Allow usage of a different audio codec per audio track. For example, OPUS for microphone capture and AAC for other audio sources.
5. Allow more than four audio tracks
6. Allow more than one audio track when using custom output
7. Support automatic file name generation for local recording when using custom output.
8. Support predefined variables for naming a file. For example, directory/<executable_name>-<date>-<time>.xxx
9. Support for 4:2:2 chroma subsampling
10. Allow to customize the base resolution of the output video without having to change the desktop resolution.
11. Improve compatibility when capturing overlays

I hope that this list is going to be useful and most of these features implemented at some point.

Thank you for making OBS,

Cristian

4. why need it?

4. why need it?

If you are recording multiple voice sources and do not want to use high bit-rate AAC for better quality, setting OPUS for such sources is useful. However, if 3. was present then there is no need for 4..

Here is an updated list after the release of OBS Studio 17.0.2.

1. Implement Frame Buffer Capture (NVFBC) and Inband Frame Readback (NVIFR) for performance reasons
2. Allow lossless audio capture when using multiple audio tracks
3. Allow more than one audio track when using custom output
4. Allow to customize the base resolution of the output video without having to change the desktop resolution

4. Just type in the resolution.

Oh lord, Point 2 would be awesome:
"Implement Frame Buffer Capture (NVFBC) and Inband Frame Readback (NVIFR) for performance reasons"

But from what I read online, it seems that those fast frame access methods are locked for other tools and work with shadowplay from Nvidia exclusively, which is very disappointing.
