How do I losslessly split videos by file size? For example, I have a 1.92GB video and I want to split it into 200MB videos.
I tried using ffmpeg and putting in -fs, -c copy, and 200000000 for 200MB, but I only got one file that's not even the correct file size. How do I properly use it?

I am building a YouTube video trimmer, and currently, it takes the YouTube video ID, downloads the whole video from the server (Even it is like 10 hours long), and then it trims it according to user's inputted timeframe using ffmpeg.
Now the problem with this is that it takes so much time to download the whole video even if we want a small piece of it hence it is highly impractical.
I was thinking to implement something like an HTML5 video player does when you seek the video forward. It just jumps to the part where you seek-ed to without downloading the part you skipped (...)

everyone,It is sorry to bother you,but i need some help.
I'm working on an embedded deployment project,doing object detection work to real-time video stream. So I have to port my c++ inference prog to RKNN1808 platform. I compile this program with CMake tool,but I cant finish my work because opencv lib cant be compiled rightly.
To FFmpeg,my configure commend is following:
./configure --enable-cross-compile --cross-prefix=/home/midsummer/Tool/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- --target-os=linux --arch=aarch64 (...)

I want to extract single frames (as thumbs) from videos, without having to download the full video file. I would like to just read the mp4 header (the info should be in the moov atom) and then download the required byte ranges. Afaik thats what browsers (HTML5 video) do when you skip to an unbuffered part
I already looked at: How can HTML5 video's byte-range requests (pseudo-streaming) work? but i can't figure out how to use it with ffmpeg for example.
Thanks a (...)
