    Good day,

  • How to speed-up ffmpeg encoding for the 'qtrle' codec

    20 mai 2024, par userxxxxxxxxx

    Need you guys help for
that I'm facing kinda limit of performance to encode clips with the codec 'qtrle'.

    


    In short,

    


      

    1. Is there GPU option or technic for the qtrle encoding by GPU ?
Can I get ANY of technic for qtrle ?

      2. 


    2. Does NVMe m.2 upgrade helps performance for ffmpeg concat and encoding ? (Currently SKHynix P41 M.2 1TB on PCIe 4 board)

      3. 


    


    (Several multiple times of re-encoding betewwen clips again again again in one loop, so that I cannot use h254 stuff.)

    


  • How to use ffmpeg device to record screen

    25 janvier 2021, par alexandreleal

    I'm trying to record the screen using the ffmpeg-next wrapper (https://crates.io/crates/ffmpeg-next) and save the result to a mkv file. There's an example in the crate's github for remuxing (https://github.com/zmwangx/rust-ffmpeg/blob/master/examples/remux.rs) and from what I've read from ffmpeg's documentation, replacing the input context demuxer with a device that captures the screen would do the trick.

    


    The input context is declared like this :

    


    let mut ictx = format::input(&input_file).unwrap();


    


    Can I change this input context to a device that captures the screen ?

    


    Thanks !
