    24 April 2018, by JoeSkurczysyn

    He tries to set the movie’s acceleration to 70 minutes so that a movie with a maximum length of 2 minutes will come out. However, FFMPEG fails. Films with a length of over 20 minutes come out, which is not what they expect.

    I write this:

    ffmpeg -i output.mp4 -filter:v "setpts=0.90*PTS" -an output2.mp4

    What am I doing wrong?

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

    19 April 2018, by 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.
