MediaSPIP : Modification des droits de création d’objets et de publication définitive
11 novembre 2010, parPar défaut, MediaSPIP permet de créer 5 types d’objets.
Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...) -

HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.
MediaSPIP allows for media playback on major mobile platforms with the above (...)

The final lib was created successfully, no error message in log file,
but when I import the lib to my Xcode Project,
the linker give me tons of errors(missing symbols like :
Undefined symbol: _pjsua_vid_codec_set_priority).
I found thepjsua_vid.ois very small(200Bytes) compare to my pjsip+openh264 build file(was 47KB), perhaps this is the reason cause the link error.

Here is my build log :

Download Instagram Livestreams [closed]
19 décembre 2020, par UnixCoonI've been looking for what Instagram livestreams can download for a long time. I can only record you via screen recording on my iPhone. But I would much rather just download it with my computer.


I've tried a lot, but I can't get the video address where a live stream is playing. I know that it is possible to download a YouTube livestream, for example, with ffmpeg.


Maybe any of you know how I download Instagram livestreams ? I would be very, very happy.


I am grateful for every answer
Greetings UnixCoon

CMTimeGetSeconds doesn't get the right video duration
26 février 2015, par JLCastillosome users don’t get the right duration of videos they capture with their own device. The funny thing is others do actually see it right, using the same device models and OS version. Anyway, we observed it in a iPhone 5c 7.1.2 and an iPhone 5s 8.1.3.
This code works for most users, but not all :
ALAssetRepresentation *representation = [mediaObject.asset defaultRepresentation];
NSURL *url = [representation url];
NSDictionary *options = @{ AVURLAssetPreferPreciseDurationAndTimingKey : @YES };
AVAsset *avAsset = [AVURLAsset URLAssetWithURL:url options:options];
videoDurationTime = CMTimeGetSeconds(avAsset.duration);I asked them to send the input videos, and this is the output from "ffmpeg -i"
