  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Can I record a video without using UIImagePickerController ?

    24 mai 2016, par SUKIYAKI

    Can I record a video without using UIImagePickerController ?
    Of course without needing to jailbreak or anything else that would cause the App Store to reject the app.

    I think there is a way to access video device not using UIImagePickerController because these camera applications can record video and work on iPhone 2G/3G which utilizes ffmpeg :

    I pick this code up by googling.

    AVFormatParameters formatParams;
    
AVInputFormat *iformat;
    

    
formatParams.device = "/dev/video0";
    
formatParams.channel = 0;
    
formatParams.standard = "ntsc";
    
formatParams.width = 640;
    
formatParams.height = 480;
    
formatParams.frame_rate = 29;
    
formatParams.frame_rate_base = 1;
    
filename = "";
    
iformat = av_find_input_format("video4linux");
    

    
av_open_input_file(&ffmpegFormatContext,
    
                 filename, iformat, 0, &formatParams);

    This code tell me how to open camera device, but I don’t know device path of iPhone.

    How do iVideoCamera and iVidCam record video ?

  • ffmpeg produces mp4 I cannot load on latest Safari on iOS

    28 mars 2016, par Michael Heuberger

    When I encode a video with these ffmpeg parameters (based on images), I cannot play that mp4 it produces on latest Safari (inside a tag) inside my iPhone 6s using the latest iOS too :

    ffmpeg 
    
-r 15.279071668502123 
    
-f image2 -thread_queue_size 64 
    
-i /home/michael-heuberger/abcd/frames/%d.webp 
    
-y 
    
-an 
    
-vcodec libx264 
    
-vf scale=trunc(iw/2)*2:trunc(ih/2)*2 
    
-crf 16 
    
-preset fast 
    
-profile:v baseline 
    
-pix_fmt yuv420p 
    
-loglevel warning 
    
-movflags faststart 
    
/home/michael-heuberger/abcd/videomail_good.mp4

    I think the above parameters should be solid. I am adding baseline and yuv420p, yet no luck on Safari 9. Why ?

    This makes it difficult for me to play videomails recorded on www.videomail.io on iOS devices.

    Am I missing something here ? Already did lots of research and tried various combinations, no luck.

    If you want to reproduce that, easy : just record a video on www.videomail.io and after that, copy the link of the recorded video page to your iPhone or just download it for local investigation.

    Any clues very welcome !

    I want to get the *'creation_time'* value using regex of the above text. I am using C#.
