Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles. Cf. : ce tutoriel ; FFMpeg avec le maximum de décodeurs et (...) -

FFMPEG does not add images to audio
20 février 2018, par GooglebotI want to create a slideshow with a background music by
ffmpeg, and use the commandffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4and map.txt is like
file '1.jpg'
duration 15
file '2.jpg'
duration 60The result is a video with the audio and blank background. If I run the above command without audio as
ffmpeg -f concat -safe 0 -i map.txt -pix_fmt yuv420p -strict -2 video.mp4a perfect video of the images (the intended slideshow) is generated (but obviously without audio).
I reckon the problem is related to synchronising the audio and images.
This is the terminal output for the first command
ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

FFmpeg audio doesnt work in converted videos but in pc it does
28 octobre 2013, par Dirk SwarzI use :
if($ext == "avi" && $convert_avi == true)
{
$convert_source = _VIDEOS_DIR_PATH.$new_name;
$conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
$converted_file = _VIDEOS_DIR_PATH.$conv_name;

$sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
$result = @mysql_query($sql);
