  • Why am I getting an error for stream #0.1 ?

    30 juillet 2014, par Rob Avery IV

    I’m converting videos using ffmpeg-php. Here is my code :

       // Set our source file
       $srcFile = $uploadFilm.".".$film_type;
       $destFile = $uploadFilm;
       $ffmpegPath = "ffmpeg";

       // Create our FFMPEG-PHP class
       $ffmpegObj = new ffmpeg_movie($srcFile);

       // Save our needed variables
       $srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth());
       $srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight());
       $srcFPS = $ffmpegObj->getFrameRate();
       if($ffmpegObj->hasAudio()){
           $srcAB = intval($ffmpegObj->getAudioBitRate()/1000);
           $srcAR = $ffmpegObj->getAudioSampleRate();
       }else{
           $srcAB = 0;
           $srcAR = 0;
       }

       // Call our convert using exec()
       //$command = $ffmpegPath . " -i " . $srcFile . " -ar " . $srcAR . " -ab " . $srcAB . "k -f flv -s " . $srcWidth . "x" . $srcHeight . " " . $destFile;
       //$command = "whoami";
       $command = $ffmpegPath . ' -i ' .'"'. $srcFile . '" -ar ' . $srcAR . ' -ab ' . $srcAB . 'k -f flv -s ' . $srcWidth . 'x' . $srcHeight . ' "' . $destFile . '" 2>&1';
       $outputCommand = array();
       $status = 1;
       exec($command, $outputCommand, $status);

    The output gives out this error at the end :

    Error while opening encoder for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height

    I know that both $srcAB and $srcAR have values because this is the command this being ran :

    ffmpeg -i source -ar 48000 -ab 160k -f flv -s 1920x1080 destination

    Of course, after the command is executed, the "convert video" has a size 0, which means it didn’t convert it.

    What am I missing here ?

  • configure : check $as first before using $gas as GNU as

    5 août 2014, par Janne Grunau
    configure : check $as first before using $gas as GNU as
    

    llvm’s integrated assembler supports the AArch64 asm on darwin since
    August 2014. So check $as first before using gas-preprocessor.pl via
    $gas. Makes the checks specific for that the architecture specific asm
    needs. PPC Altivec and AArch64 needs on ’:vararg’ for macro arguments.
    Arm needs in addition the ’.altmacro’ directive.

    • [DBH] configure
  • make video from image file using ffmpeg

    4 août 2014, par Roylisto Putra Pradana

    i have 64 images sequence and i want to make a video using that images.

    you can download the images here

    i use ffmpeg in ubuntu.
    here’s my command

    ffmpeg -r 60 -f image2 -s 1360x768 -i "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/tmp/result%d.png" -vcodec libx264 -crf 20 "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/render/test.mp4"

    it works but only 39 images has generated to a video. My question is why ffmpeg not render all images in that folder into a video, what is my mistake and how to solve it ?
