How much RAM does FFMpeg need?

it really depends on what you doing with the server and the ffmpeg. if it is for a single site were once in a while you upload a video, then 4 giga RAM and a single core server will be enough, if it is for hosting multiple sites then you need a server with more resources.

Does FFMpeg use GPU or CPU?

the CPU\% has been more than 90 (375\%). In case of ImageMagick, if I enable opencl while configuring, then the app will run in GPU, i.e., the CPU\% will be less than 90. I noticed that. But in case of ffmpeg, it is GPU accelerated one.

Is FFMpeg CPU intensive?

You can’t limit FFMpeg to a percentage of CPU use, but you can set the -threads parameter on your FFMpeg call, if you have 4 cores try set it to -threads 2 that should limit you to around 50\% CPU. Another solution might be to lower the priority on your FFMpeg process, to something lower than your applications.

How much space does FFMpeg use?

While slow, FFmpeg’s memory use only went up to about 0.6 GB. The resulting file was 300 MB, and I can’t see any loss of quality compared to uncompressed frames (so -crf 20 might have been a bit too low). The truth is video encoding a CPU and memory intensive job.

Does FFmpeg use graphics card?

FFmpeg uses Video Codec SDK If you have an NVIDIA GPU which supports hardware-accelerated video encoding and decoding, it’s simply a matter of compiling FFmpeg binary with the required support for NVIDIA libraries and using the resulting binaries to speed up video encoding/decoding. Hardware-accelerated decoding of H.

How many cores does FFmpeg use?

A single ffmpeg process will max out a 1 CPU box instantly. It is also single threaded, so you shouldn’t run more than one per the number of CPUs you have – ie. if you have a Quad core box, never run more than 4 at a time.

Is VLC based on FFmpeg?

The libavcodec library from the FFmpeg project provides many of VLC’s codecs, but the player mainly uses its own muxers and demuxers.

Is FFmpeg MP4?

This is the input file. FFmpeg can input most container formats natively, including MP4, . ts, MOV, AVI, Y4M, MKV, and many others. Note that unless you identify an audio or video codec via switches, FFmpeg will use the default codecs for each container format as well as reasonable encoding parameters.

What is AMD AMF?

Specifically, developers can use the AMF SDK for accessing AMD media accelerators for video encoding and decoding and color space conversions. The AMF SDK allows optimization of application performance by utilizing CPU, GPU compute shaders and hardware accelerators for media processing.

What is h264_nvenc?

h264_nvenc uses the NVidia hardware assisted H. 264 video encoder. libx264 is a software (CPU) based H. 264 encoder. I would guess that libx264 delivers better quality than h264_nvenc for the same bitrate.

What is the total core/memory requirement for FFmpeg?

HLS + watermark – Memory Usage stayed between 430MB to 1.1GB FFMPEG is a power eater. The total number of core/memory requirement will depend majorly on how much video you want to process.

How do I reduce the amount of memory used by FFmpeg?

With ffmpeg running, open the System Monitor. Scroll down to the process named ffmpeg, left click it to select, right click it, and set the priority to “Low” or “Very Low”. If you’re worried about memory usage, too, know that it is not possible to tell a process to only take so much memory and still run.

How do I run FFmpeg from command line?

Command line is that black window you find by clicking [windows+r] and typing cmd then hitting enter. This is also called “command prompt”. Once setup you enter ffmpeg commands in one of these windows to use it.

How to install FFmpeg on MacBook Air?

Go to the ffmpeg download site and download the zip file that best fits you computer’s specs. Choose “static” linking and the “nightly git” version for the most current usability. Create a folder on your computer to uppack the zip file.
