ffmpeg not returning anything on Dash
10 janvier 2021, par whatcrisisI am trying to extract subtitles from an MPD, but ffmpeg is not returning anything. If I try first a simple command such as :


ffmpeg -i Downloads\Manifest.mpd



After just 2 seconds it stops. This is the log :

So basically, it did nothing. I have libxml2 installed and I am confused since there is no error at all. Any help ? Thank you !

How to calculate byte/index ranges for mpeg-dash MPD file ?
7 avril 2016, par TheSHEEEPI basically know how an .mpd file would have to be structured to support streaming from separate .mp4 (or webm) files.
However, I would like to implement the "static" (aka "on-demand") method, thus only having one file per quality that I want to offer in the stream.
In all samples, this is done by supplying the indexRange & range values within a Representation like this :
<representation bandwidth="2073921" codecs="avc1.4d401f" height="720" mimetype="video/mp4" width="1280">
<baseurl>car-20120827-88.mp4</baseurl>
<segmentbase indexrange="708-1183">
<initialization range="0-707"></initialization>
</segmentbase>
</representation>What I could not find out anywhere is how one would calculate the indexRange/range values here, using only ffmpeg (or ffprobe).
What exactly would one have to do to get those numbers right for arbitrary (yet supported, of course) video files to create the .mpd file for them ?Or am I trying to figure out something in vain here and those values are just arbitrary ?
