  • What happens when I use too much RAM from spawning process with Popen in Python ? [closed]

    2 février 2020, par lms702

    I have a Python script that is rendering a video with FFmpeg where I have all the images and audio I need. I am currently invoking FFmpeg via multiprocessing.Popen, which works very quickly on my computer but the Task Manager shows that I am using 12 GB of RAM while doing so (since there end up being 100s of instances of FFmpeg.exe running). I want to deploy this on a linux server one day with much less RAM, but I worry that I’ll run into problems with my approach. Does Python/the OS handle this or should I limit the number of processes I spawn myself ?

  • Why are the actual QP values in block-level in minus 3 from the initial QP with CQP mode in x265 ?

    27 septembre 2022, par Alearner

    I am encoding a video with different initial QP values using the x265 encoder. I am surprised when I checked the bitstream to see the actual QP values for every block across frames are not exactly the same as the given initial QP value. Specifically, the actual QP decreases to minus 3 from the initial value, as shown in the figure below (my initial QP is set to 27). But I don't understand why. Then, I run the encoder from HM-16.20, the actual QP value is the same as the initial QP. Can someone help me to understand the motivation for this ? From my point of view, the x265 encoder wants to retain more visual quality by lowering the actual QP values than those in HM software. I used the following command line to run the x265 encoder :

    


    x265.exe --input BQSquare_416x240_60.yuv --fps 60 --input-res 416x240 --interlace 0 -f 20  --input-depth 8 --input-csp i420 --ctu 64 --no-open-gop --keyint 1 --ref 1 --aq-mode 0 --qp 27 -r BQSquare_416x240_8bit_27.yuv --output-depth 8 --output BQSquare_416x240_8bit_27.bin

  • How to convert kivy to a video file

    16 juillet 2016, par lucemia

    I wrote a kivy app to render some animation on linux server.
    Is there a good way to convert the animation to a video file directly ?

    Currently I tried Xvfb + ffmpeg approach. However it has some issues I want to avoid such as :

    • ffmpeg will also record the empty x-windows desktop before the animation start.
