    I’m converting a single video into multiple videos at different resolutions. But it’s painfully slow. how can I speed this up ?

  • how do I set speed rate (ex:double speed) in FFmpeg library ?

    19 avril 2018, par geeeek

    I’m working on rtsp live video from ffmpeg and rendering it on the screen.

    However, the image is displayed after 1 to 2 seconds.

    to reduce video delay, So I want to increase the playback speed in my program.

    int64_t duration = m_formatCtx-> duration;
    
duration = duration * 1000;
    
av_seek_frame (m_formatCtx, m_videoStream, duration, AVSEEK_FLAG_ANY);
    
av_seek_frame (m_formatCtx, m_audioStream, duration, AVSEEK_FLAG_ANY);
    
while (av_read_frame (m_formatCtx, & m_packet)> = 0)

    I can not get the result I want in this way.

  • Youtube-dl and Shell speed

    7 août 2016, par JJ The Second

    So I’ve been experimenting with youtube-dl on Ubuntu 14 recently and I should say downloading is well fast even I have a 1GB Ubuntu LAMP but when it comes to triggering FFMPEG and deleting process hangs for a good time. Even worked with -k but as soon as FFMPEG process is completed, it takes time to respond. I do understand this is a big subject but I’d really like to hear your thoughts, what amazes me is how a website like thisis running in less than a second ? Here is what I have,

    youtube-dl "http://www.youtube.com/watch?v=UxxajLWwzqY" --write-info-json  --extract-audio --audio-format mp3  -o "/var/www/html/download/%(title)s.%(ext)s"

    I really don’t understand how this is done so fast ? Is there anything I’m missing ?

    Thanks for your time.
