  • Creating a video from data of server-side script

    8 mars 2016, par Peter Leupold

    My plan is to display the data that a server-side script generates in a video displayable on my web page. So far my approach is the following :

    1. A three dimensional integer array in a C script is use to accumulate the image data. Dimensions are width, breadth and color (R, G and B).
    2. The array is written to a ppm-file.
    3. The next picture is accumulated and written and so on.
    4. With ffmpeg a script merges the ppm-files to a mp4-video.

    Basically this works, but of course faster would be nicer. I would appreciate proposals for fundamentally different approaches as well as help on the following details :

    • Is there a file format simple as ppm that uses the HEX code for colors instead of triplets ? This would reduce the size of my array as well a the number of write operations.
    • Do I loose much time if I print every single value to the file with an fprintf operation instead of accumulating lines into a string ? Or do compilers optimize this kind of sequences of writes ?

  • Live streaming to YouTube over HLS with FFMPEG [closed]

    19 septembre 2022, par Ash Raj

    When I stream my FaceTime camera to YouTube over HLS, my video freezes every couple seconds. Which settings do I have wrong, or am missing ?

    


    ffmpeg \
-f avfoundation \
-framerate 30 \
-video_size 1920x1080 \
-pixel_format yuyv422 \
-probesize 10M \
-i "0:0" \
-c:v hevc_videotoolbox \
-b:v 4500K \
-tag:v hvc1 \
-c:a aac \
-method POST \
-f hls \
"https://a.upload.youtube.com/http_upload_hls?cid=STREAM_KEY&copy=0&file=index.m3u8"


    


    I'm troubleshooting this with my FaceTime camera right now, but I plan on using a capture card with a 4K studio camera after I get this working

    


  • How to restrict CPU load of FFmpeg call ?

    9 septembre 2022, par rattlesnake

    As described here, for example, I'm using FFmpeg to check video file integrity like this :

    


    ffmpeg -v error -i input.mp4 -f null -


    


    Since I plan to run this in the background, I want to limit the CPU load. I already tried -threads 1, -filter_threads 1, -filter_complex_threads 1. Nothing helps and FFmpeg still uses as many cores as it can get. Which parameter am I overlooking ?
