Does ffmpeg use RAM?
ffmpeg does not use any RAM, that it not actually needs.
Does ffmpeg use multiple cores?
it depends on codec used, ffmpeg version and your CPU core count. Sometimes it’s simply one thread per core. Sometimes it’s more complex like: With libx264 it is cores x 1.5 for frame threads and cores x 1 for slice threads.
Is ffmpeg open source?
FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams.
How much memory does Ffmpeg use?
The main problem I encounter is that ffmpeg each 5 seconds consumer a range of 116-128 K of ram memory more. It never stops of taking more and more memory.
Does FFmpeg use GPU?
FFmpeg with NVIDIA GPU acceleration is supported on all Linux platforms. To compile FFmpeg on Linux, do the following: Clone ffnvcodec.
Why is FFmpeg so slow?
If your CPU usage is still low after FFmpeg has managed to seek to the defined point in the video, it’s likely due to one or more of the filters you’re using. Some filters may not be able to use all the available CPU threads, and some filters aren’t even multi-threaded.

- Offer fewer bitrate tiers.
- Ensure that x264 is using CPU capabilities.
- Use a faster x264 encoding preset.
- Make sure your ffmpeg and the linked x264 are not super old.
- Stream copy the audio instead of re-encoding it if the input audio format is compatible with your output.
