Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -

make video from image file using ffmpeg
4 août 2014, par Roylisto Putra Pradanai 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 commandffmpeg -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 ?

configure : check $as first before using $gas as GNU as
5 août 2014, par Janne Grunauconfigure : 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. -
Why am I getting an error for stream #0.1 ?
30 juillet 2014, par Rob Avery IVI’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 ?
