Description (last modified by Carl Eugen Hoyos)

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

comment:2 by Chris Woods, 15 months ago

This is still an issue in latest ffmpeg builds. Some DASH manifests seem to cause ffmpeg to incorrectly calculate the segment numbers. This behaviour is being noticed in various programs which depend on ffmpeg for DASH playback.

A working example, using mpv
