  • 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 !

  • Get 'creation_time' of video using ffmpeg and regex

    5 février 2014, par Foysal

    I have a metadata text of a video file which is produced by ffmpeg.

    Metadata:
    
    major_brand     : qt  
    
    minor_version   : 0
    
    compatible_brands: qt  
    
    creation_time   : 2011-09-10 21:44:22
    
    model           : iPhone 4
    
    model-deu       : iPhone 4
    
    encoder         : 4.3.5
    
    encoder-deu     : 4.3.5
    
    date            : 2011-09-10T17:44:22-0400
    
    date-deu        : 2011-09-10T17:44:22-0400
    
    location        : +40.7329-073.9864/
    
    location-deu    : +40.7329-073.9864/
    
    make            : Apple
    
    make-deu        : Apple

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