Is youtube-dl able to pass query string parameters to individual dash segments?

[stinkteeth]

I apologize in advance if this is a simplistic question that should be obvious. I searched and checked the youtube-dl documentation as carefully as I could before posting this issue. Again, please forgive me.

Suppose that a dash manifest (mpd) url contains query string parameters as part of the manifest url that are necessary for downloading the manifest, Something like this:

hxxp://someurl.com/manifest.mpd?auth=0000

So, youtube-dl is able to download the manifest mpd successfully, but then when it goes to download the individual m4s dash segments, there is a 403 error because each of the m4s segments requires the "?auth=0000" parameter as part of the url to each segment, and youtube-dl does not pass this parameter when it attempts to download each individual m4s segment.

I got around this using a filter in fiddler. But is there some option that will cause youtube-dl to pass the query string parameters (provided with the mpd url) to each of the m4s segment urls?

I thought perhaps --external-downloader-args ARGS might work, but no.

No such option exists.

Thanks for the prompt response!

@dstftw is this on the radar for the future? I would love to get this feature for HLS. Admittedly I have very little understanding of how youtube-dl works but this doesn't seem like a very difficult issue to solve. If this issue could be at least reopened to keep track of the request that would be great.

@stinkteeth I was wondering if you could explain yourself a bit more about how you fixed this in Fiddler.
Thanks
