  • How to speed up video conversion

    9 mai 2016, par Arheisel

    I’m currently working in a proyect that involves converting large series of .jpg (>6000) into video format. These frames (320x240) are stored in folders at a rate of 2.5fps. Generating a couple of folders every hour that need to be converted ASAP.

    For now i’ve tried copying the folder to a ram disk and using avconv wich takes about a minute.

    Here is my command :

    avconv -threads auto -y -r 2.51 -i %03d-capture.jpg -s 320x240 -r 25 video.mpeg

    could ffmpeg work faster ?
    is there a way to speed it up ?
    wich video format take less time to convert to ?

  • Speed of moving text drawtext filter - FFMPEG

    8 mai 2016, par BOB

    I’m using this command to move text from one place to another using ffmpeg

    ffmpeg -i VideoInput.mp4 \
    
       -vf "drawtext=enable='between(t,12,14)':fontfile=myfont.otf:text='Test test': \
    
           x='x1+(x2-x1)*(t-t1)/(t2-t1)':y='y1+(y2-y1)*(t-t1)/(t2-t1)':fontsize=65" \
    
       -acodec copy outputVideo.mp4

    Now I need to control the speed of moving the text. I want to speed it up.
    How do I control the speed ?

    Any suggestions ?

    Thank you

  • avcodec/mpegaudio_tablegen : speed up dynamic table creation

    avcodec/mpegaudio_tablegen : speed up dynamic table creation

    This does some miscellaneous stuff mainly avoiding the usage of pow to
    
achieve significant speedups. This is not speed critical, but is
    
unnecessary latency and cycles wasted for a user.
    

    All tables tested and are identical to the old ones
    
(bit-exact even in floating point case).
    

    Sample benchmark (x86-64, Haswell, GNU/Linux) :
    
old :
    
102329530 decicycles in mpegaudio_tableinit,       1 runs,      0 skips
    

    new :
    
34111900 decicycles in mpegaudio_tableinit,       1 runs,      0 skips
