XMP PHP
13 mai 2011, parDixit Wikipedia, XMP signifie :
Extensible Metadata Platform ou XMP est un format de métadonnées basé sur XML utilisé dans les applications PDF, de photographie et de graphisme. Il a été lancé par Adobe Systems en avril 2001 en étant intégré à la version 5.0 d’Adobe Acrobat.
Étant basé sur XML, il gère un ensemble de tags dynamiques pour l’utilisation dans le cadre du Web sémantique.
XMP permet d’enregistrer sous forme d’un document XML des informations relatives à un fichier : titre, auteur, historique (...) -

Cannot use Mobile FFmpeg and LibVLCSharp together in Xamarin.Forms project
26 février 2021, par Travis PI am adding video stream capture functionality to a Xamarin Forms project. I am trying to use VLC's LibVLCSharp.Forms (https://github.com/videolan/libvlcsharp) package and the Mobile ffmpeg Xamarin wrapper package, Laerdal.Xamarin.FFmpeg.* (https://github.com/Laerdal/Laerdal.Xamarin.FFmpeg.iOS). However, the internal ffmpeg library from VLC is conflicting with the ffmpeg wrapper and is built with different flags which exclude functionality that I need.


For native development, it looks like you can configure a preferred library with the
OTHER_LDFLAGSflag in thePods-<your app="app">.debug.xcconfig</your>file but I don't see where to do that with Xamarin.Forms.
Source : https://github.com/tanersener/mobile-ffmpeg/wiki/Using-Multiple-FFmpeg-Implementations-In-The-Same-iOS-Application

How can I configure Xamarin iOS builds to prefer the mobile ffmpeg library over the VLC ffmpeg library ? If I am able to use the mobile ffmpeg library, will it cause issues with VLC ?


Here is a log message when I try to run commands with ffmpeg. As you can see, ffmpeg's internal library paths reference "vlc" :

ffmpeg does not copy custom metadata
20 juin 2015, par e110c0I’m trying to fix some videos made with an iDevice. The videos have a rotation in the metadata which is only understood by Apple and its software but noone else. Fixing this is quite simple, but I also would like to keep the other metadata in the files like the geolocation.
I tried a couple of versions, all with the same result, e.g. :
ffmpeg -i input.mov -vf vflip,hflip -map_metadata 0 -metadata:s:v:0 rotate=0 -acodec copy output.mp4This should work, it already gives the correct preview of metadata :

handler_name : SoundHandlerI also tried to add the one tag I’m interested in by hand with
-metadata:g location=+48.2683+007.7205+172.710/with no change in the result.
Output as .mov doesn’t change anything, neither.
Is there any trick to add non-standard metadata ? How do I get the location back in there ?
Thanks in advance to anyone who can give some insight on this.

ffmpeg - Audio not playing on iOS with transcoded video
23 juin 2015, par DevI am using Laravel 4.2.
I am working on a project that provides video services. To transcode video (to play on all devices) I’ve used git-hub package
php ffmpeg.By transcoding video, I found it is
NOTworking with iPhone 5s. I searched for solution and found some changes in parameters passed to the library.Finally, I come up with the command below that the library uses to transcode the video.
ffmpeg -y -i video.mp4 -async 1 -metadata:s:v:0 start_time=0 -s 560x320
-vcodec libx264 -strict experimental -pix_fmt yuv420p -profile:v baseline
-acodec aac -profile:a aac_low -b:v 466k -refs 6 -coder 1 -sc_threshold 40
-flags +loop -me_range 16 -subq 7 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4
-trellis 1 -b:a 256k -ac 2 transcode_video.mp4The video is playing well but the audio is NOT working on iOS. Hence the video is playing without audio. I am using HTML 5 player to play the video and auto play option is off.
Any suggestions ?
