I've read enough thread about how even 64GB Ram with 32 core fails to keep up with FFMPEG so your best bet is to first improve your command or segregate commands into smaller command to handle the resources as effectively as possible While we tend to first conclude that more resource = more stability is not always right. Increasing resource is not always the answer.Always run FFMPEG in an isolated machine away from your webserver, database, mail server, etc.Processing videos in a batch-wise will ensure optimum use of available resources and lesser chance for breaking your system in the middle of the night ![]() It's never a good idea to run parallel FFMPEG.In my case, We only wanted to support upto 500MB videos so our test for 4K video processing is fitting the need but if you have larger video requirement then you have to test with more RAM/CPU core at hand The total number of core/memory requirement will depend majorly on how much video you want to process. HLS + watermark - Memory Usage stayed between 380MB to 850MB.transcoding to H264 - Memory Usage stayed at 800MB.4K HEVC LG HDR video of 1.13 minute long (448MB).HLS + watermark - Memory Usage stayed between 430MB to 1.1GB.transcoding to H264 - Memory Usage stayed at 750MB.4K HEVC iPhone video of 1.2 minute long (453MB).You might even wanna remove line 53 depending on your use case. This will eliminate the overloading of all filters in memory at once. So now we are running FFMPEG inside a loop to handle per resolution basis output. Let me know how I can tackle this problem. I have thought about ulimit but this does seem like restricting FFMPEG instead of writing an improved command. Even if we decide to work without watermark, It still hangs around 1.8GB RAM for processing 5 seconds 4K video and this create a risk of what if our user upload rather longer video than it will eventually crash down the server. I understand that FFMPEG requires high amount of memory consumption but I am unsure what's the exact way to process video without holding the stream in the memory but instead release any memory allocation in real-time. ffmpeg amerge Error while filtering: Cannot allocate memory. ![]() So I looked out for some similar question: Now this works flawlessly in videos from Youtube or other sources but as soon as I am trying to use 4K videos from iPhone, the RAM usage grows from 250MB to 3.8GB in less than minute and crashes the entire process.
