  • Change the framerate of a video including audio without re-encoding using ffmpeg

    12 août 2018, par Trojaner_

    I have a 30.02 FPS .mp4-video and I’m trying to convert it to 30 FPS. I found this question but if I try the method like described in the first answer the audio gets lost because the video is getting converted in a .h264-file which can’t contain audio as I read here.

    (I’m sorry if i’ve got issues with the english language, it isn’t my mother language)

    EDIT : Here goes the content I enter in the terminal and the output that returns

    Input : ffmpeg -y -i 01.mp4 -f h264 -c copy temp1.h264

    Output : (I replaced the real paths with path\to\...)

  • intreadwrite : Add intermediate variables in the byteswise AV_W*() macros

    1er août 2016, par Martin Storsjö
    intreadwrite : Add intermediate variables in the byteswise AV_W*() macros

    This avoids issues with expanding the argument multiple times,
    
and makes sure that it is of the right type for the following shifts.
    

    Even if the caller of a macro could be expected not to pass parameters
    
that have side effects if expanded multiple times, these fallback
    
codepaths are rarely, if ever, tested, so it is expected that such
    
issues can arise.
    

    Thefore, for safety, make sure the fallback codepaths only expand
    
the arguments once.

  • Install ffmpeg-php with PHP 5.3.x [closed]

    4 octobre 2012, par Proloy

    I know that this question has been asked many times on this site. I tried all and nothing works for me. I also saw some rumor that ffmpeg-php doesn't work well with PHP 5.3.x.

    I am totally fed up. My FFMPEG-PHP worked fine for PHP 5.2.x but after I upgraded to PHP 5.3.x it stopped to show in phpinfo().

    I have a centOS 5.8 box.

    Can anyone tell me why this happened ?
