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 {$input} | grep rotate
below is my final command to convert a video to mp4
"ffmpeg -i {$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.
Output console of ffprobe command :

NGINX RTMP convert flv to hls ?
3 mai 2016, par MandelDuckI have a server that takes an rtmp stream and saves it as flv.
Web users can view the flv video in their browser, however iPhone users can’t as it is flash
Is there away to convert the saved flv files on the fly to hls for the iPhone viewers ?
here is my config, Webusers access the vod application
rtmp {
server {
listen 1935;
chunk_size 4096;
application live {
live on;
record all;
record_path /videos/av;
idle_streams off;
}
application audio {
live on;
record audio;
record_path /videos/audio;
idle_streams off;
}
application vod {
play /videos/av;
}
application aod {
play /videos/audio;
}

Reading geolocation data from a video file using FFMpeg/Xuggler
23 décembre 2015, par agent154Using the MediaInfo application, I am able to see that a file taken with an iPhone 5 contains geolocation metadata, tagged both with ©xyz and com.apple.quicktime.location.ISO6709. I am not able to find any way to get this data using xuggler, however.

com.apple.quicktime.software : 8.4.1
com.apple.quicktime.model : iPhone 5As an aside, there seems to be a lot of metadata on this file that I can’t immediately find while debugging via xuggler.
The question at Reading Geolocation from Quicktime Movies with Java (Xuggler) ? is asking the exact same question, but has no answers or comments at all, and is over 4 years old.
Is anybody aware of a way to be able to get this data using xuggler as it is, or how I can modify the source and re-compile to make it work ? I am required to get this data for a work project. Thanks.
