  • 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" (...)

  • FFmpeg-generated .m2v file shows strange video length

    15 août 2016, par John Doe 2

    I created a .m2v file using ffmpeg like this :

    ffmpeg -framerate 1/300 -s 720x576 -i img%3d.jpg -c:v mpeg2video -b:v 2000k -r 5 video.m2v

    This worked successfully, but if I right click on the .m2v file and go to details and scroll to video length I get this information which is really strange ( Using Windows 10) :

    Video
    

    
Length: 256204778:48:05

    If I run the .m2v file with a program like PowerDVD the length of the video is 5 minutes long.

    Why does this happen ?

    Enforce effective motion vector search range

    This commit explicitly enforces the effective motion vector range
    in the motion search stage. The range needs to be the intersection
    of UMV border, effective absolute motion vector value range, and
    the target search area.

  • How to get iOS App Preview video bitrate in range

    29 avril 2019, par JKaz

    Creating new App Previews for App Store Connect has always been difficult. Time to do it again (new app version) and running into same issue without resolution this time.

    Making the video is easy enough, recording it with Quicktime and either a connected device or through Simulator (and the xcrun simctl io booted recordVideo <filename>.<file extension="extension"></file></filename> Terminal command).

    I can open that in iMovie, create a new App Preview, and export/share the preview with proper size, length, frame rate per Apple specs. But the bit rate is always too low ( 4 mbps) and it’s required to be 10-12 mbps (and I’ve had video reject be/c of that). In the past I could always make some change to the .mp4, in conjunction with something like ffmpeg -i ~/appVideo.mp4 -b:v 11M ~/appPreview.mp4 to get the file into the target range, but that’s not helping today, and neither is Developer Tech Support.

    Apple’s documentation says :

    To export the final video, click Share in the toolbar, then choose App
    Preview. The export settings are automatically configured to meet App
    Store requirements. iMovie exports the final video at the correct
    resolution based on the device from which your clips were captured.

    I’ve done that and more, and bit rate is still out of range (every other attribute is in spec). I’ve tried the recommendations from a bunch of other threads here for http://video.online-convert.com/convert-to-mp4 and others, and none seem to do the trick. Am I missing something obvious re bitrate ? Is it this hard for everyone ?

    Thank you.
