  • iOs : Low frame per second(fps) for VGA resolution

    26 juillet 2014, par Bhuvan Balasubramanian

    I’m facing an issue in broadcasting video from one iPhone to another iPhone.

    The issue is when I view the friend’s live video in my iPhone, the frame per second(fps) is very low(it is 12fps). Video quality and audio is looking fine but the only problem is fps.

    I don’t know where I need to config/change the code to convert from variable fps to constant fps. Also to increase the fps as **24/30**.

    The resolution I used for broadcasting

    RESOLUTION_VGA,     // 480x640px (landscape) & 640x480px (portrait)

    I’m using following libraries for streaming

    1. MediaLibiOS - link
    2. Ffmpeg-2.2.1
    3. CommLibiOS
    4. libx264-r2409

    Wowza is a Media Server and iOS target version is 7.0

    Please help !

    Thanks in advance.

  • Why UA sniffing is generally bad, real-world example #1048577 : "That time a missing /s on navigator.userAgent (based on single-digit UA version assumptions) broke SM2 on iOS 8+ devices."

    1er septembre 2014, par scottschiller
    Why UA sniffing is generally bad, real-world example #1048577 : "That time a missing /s on navigator.userAgent (based on single-digit UA version assumptions) broke SM2 on iOS 8+ devices."

    The upside : The fix is adding \s to a UA regex check targeting legacy iOS devices with broken HTML5 Audio support, so that the "OS 10 " portion of the UA string does not match the pattern "OS 1 ".
    

    This is a pre-emptive fix for the pending iOS 8 release, which reportedly includes the string "iPhone OS 10_10 like Mac OS X". Due to SM2 checking for /os ([12|3_0|3_1])/i which had broken HTML5 Audio() support, and not considering the far future possibility of "iOS 10" being included in the userAgent string at the time, HTML5 audio is incorrectly disabled on iOS 8 beta 3 and is likely to apply to the final iOS 8 release.
    

    This is a good example and reminder of why UA checks are generally bad, and dangerous ; similar issues hit other libraries doing UA and plugin checks both client and server-side when IE hit 10, and Flash hit version 10, so this iOS pattern change may affect some other libraries targeting iOS as well.
