  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Find a resolution (dimension) of a video object saved in S3 - in rails

    27 septembre 2015, par JVK

    I have video files saved in s3 and I want to find the dimension/resolution of any file (lets assume file sizes are in 500mb) per the request comes in my rails app.

    One of the options, I have in my mind is :

    Download (getObject) the file in local memory and use ffmpeg to find the required info. I currently don’t have ffmpeg, as I don’t need that for any task.

    But, I don’t like this option, reason is - I don’t want to waste bandwidth to download it first (takes time) from S3 and then run cpu and memory intensive ffmpeg on my server to merely find the dimension/resolution of the video.

    Is there any better solution ?

    S3 object HEAD call on object unfortunately doesn’t return dimension information.

  • dnxhddec : Decode and use interlace mb flag

    dnxhddec : Decode and use interlace mb flag

    This bit is 1 in some samples, and seems to coincide with interlaced
    
mbs and CID1260. 2008 specs do not know about it, and maintain qscale
    
is 11 bits. This looks oversized, but may help larger bitdepths.
    

    Currently, it leads to an obviously incorrect qscale value, meaning
    
its syntax is shifted by 1. However, reading 11 bits also leads to
    
obviously incorrect decoding : qscale seems to be 10 bits.
    

    However, as most profiles still have 11bits qscale, the feature is
    
restricted to the CID1260 profile (this flag is dependent on
    
a higher-level flag located in the header).
    

    The encoder writes 12 bits of syntax, last and first bits always 0,
    
which is now somewhat inconsistent with the decoder, but ends up with
    
the same effect (progressive + reserved bit).
