    ffmpeg presets are :

    ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow and placebo

    How should my json request look like if i want as encoding speed slow ?

    My json so far :

    {
    
    "query": {
    
        "userid": "79943",
    
        "userkey": "XXX",

  • Speed up and reverse a video with a single command ?

    4 août 2016, par Eduardo Perez

    I am using Ubuntu 16.04. I know with FFMPEG you can use this command to reverse a video.

    ffmpeg -i [input] -vf reverse -af areverse [output]

    Now, the thing is I found somewhere that you can use this command to speed up the video.

    ffmpeg -i [input] -filter_complex "[0:v]setpts=2.0*PTS[v];[0:a]atempo=0.5[a]" -map "[v]" -map "[a]" [output]

    So, I tried this command to speed up and reverse the video, but it didn’t work since complex filters can’t be used together with -vf or -af.

    ffmpeg -i [input] -filter_complex "[0:v]setpts=2.0*PTS[v];[0:a]atempo=0.5[a]" -map "[v]" -map "[a]" -vf reverse -af areverse [output]

    What command do I need to use to get FFmpeg to speed up and reverse the video, without decompiling it ? I’m using the latest version of FFmpeg.

  • How to profile compression speed for a h264 encoder

    25 mai 2018, par Dean

    I’m using nvenc to compress in h264 a video stream. I now have a kinda-working low latency implementation for game streaming purposes but I’m struggling to get reliable profiling results. I’ve been trying to stream a video (so everything is predetermined) via my encoder to the clients in controlled network conditions (e.g. locally). I tried to time average compression times per frame but they’re highly volatile and the numbers I get aren’t that meaningful.

    How are low latency streaming encoders tested for performances ?
