Dash demuxer does not stop after -t <timeout> expires

Reported by:	Aman	Owned by:
Priority:	normal	Component:	avformat
Version:	git-master	Keywords:	dash

Description

Summary of the bug:

When using -t <timeout> on an output being fed by a dash muxed input, the ffmpeg process does not stop when the timeout is reached. No output packets are created, but the input keeps reading until the source EOFs.

How to reproduce:

Below you can see that time=00:00:01.96, but fps and speed approach 0 while the process keeps running and printing out "Opening segment-XX.m4s"

The input does not matter, try any mpd url.

Replying to tmm1:

The input does not matter, try any mpd url.

Please provide a sample. The current ffmpeg does not support mpd with byte range info.
