Detect rotation angle and rotate final video using ffmpeg version 2.8
3 février 2016, par Hemant KumarI used to work on ffmpeg 2.2 until now and was detecting rotation angle of video uploaded from android / iPhone mobiles and rotate the resulting video so that it run perfectly on a correct angle.
But since I have updated the ffmpeg to version 2.8 I am getting this rotation problem. My queries are not rotating the videos as they were earlier.
Here’r the commands I was using :
To check rotation angle :
ffprobe -of json -show_streams {$input} | grep rotatebelow is my final command to convert a video to mp4
"ffmpeg -i {$input} -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ".fix_video_orientation($input)."' -threads 0 -ab 64k -s {$resolution} -movflags faststart -metadata:s:v:0 rotate=0 {$output}";"fix_video_orientation" function is given below. It detect the angle of rotation of the initial video and output optimal option for rotating the final video.
function fix_video_orientation($input){
$return= ", transpose=1 ";
$dd= exec("ffprobe -of json -show_streams {$input} | grep rotate");
if(!empty($dd)){
$dd=explode(":",$dd);
$rotate=str_replace(",","",str_replace('"',"",$dd[1]));
if($rotate=="90")return $return;
else if ($rotate=="180") return ", transpose=2,transpose=2 ";
else if($rotate == "270") return ", transpose=2 ";
}Currently above script is supporting "flv","avi","mp4","mkv","mpg","wmv","asf","webm","mov","3gp","3gpp" extensions, also the script is supporting the resulting .mp4 file to play on all browsers and devices.
Now the ffprobe command is not returning rotation angle and so a portrait video if uploaded from iphone is showing as landscape on the website.

Anomalie #4189 : extraire_multi mélange un /li /ul final avec le de langue ajouté par code_...
17 novembre 2018, par jluc -Ce bug révèle peut être un pb conceptuel dans la manière qu’a extraire_multi de parfois ajouter des div en début et fin de texte lors de ses traitements intermédiaires. Ç’a peut être été conçu à l’origine avec l’idée qu’il n’y aurait que des éléments inlines dans une chaîne traitée, et pas de balises html, alors que maintenant il y a des blocs et des balises. Et l’astuce initiale, qu’on peut qualifier de hack, se trouve devenue foireuse dans certains cas.
