  1. The Firefox/Chrome add-on Easy Video Downloader sees these segments and will download them BUT, as far as I can tell, there's no way to automatically get all of them so I"m seeking guidance to grab segments. Firefox's The Stream Detector recognizes the mpd but doesn't create functioning commands for either ffmpeg or streamlink.

    Here's an example (HIDETHIS and DATAxx are placeholders to anonymize and make this easier to view:

    Code:

    The goal is to retrieve the largest video and highest bitrate audio which are these lines:

    Code:
    <Representation audioSamplingRate="48000" bandwidth="127000" codecs="mp4a.40.2" id="DATA09"></Representation>
    <Representation bandwidth="1997000" codecs="avc1.4d001f" frameRate="2997/125" height="720" id="DATA19" width="1280"></Representation>
    The "best" solution would probably be a universal method to download all segments for joining later. I've tried many other browser add-ons and only a very few recognize the source video. None properly grab the segments.

    So...the "real" solution might be a template for ffmpeg, youtube-dl, or streamlink to which stream-specific values are copied. Awkward, but if it works....
