 Hello,

 using the latest static build ffmpeg version N-57631-gebedd26eef-static
 I want to read mpd and convert to mpegts - this part works ok,
 except one manifest
 looks like ffmpeg make wrong calculation for $Number$

 In my case I have
 availabilityStartTime="2021-05-27T11:59:16Z"
 media="$RepresentationID$-$Number$.m4s"
 duration="180180"
 startNumber="487925"
 presentationTimeOffset="89360526151"

 I expect $Number$ to be converted to 488430 (and other players do so), but
 ffmpeg try retrieve 397033568


 here is full manifest
