I use the MP4BOX to command MP4BOX -frang 10000 -dash 30000 test.mp4

and then generate some files and a mpd file.

MP4Client can play this mpd successed.

But it is the single bitrates.

But I want to use MP4Client to play the MPEG-DASH(mpd) and it can change
different bitrates.

I need help to solve this problem. Thanks.

My dashcast.conf Content is

[v1]

type=video

bitrate=400000

width=640

height=480

[v2]

type=video

bitrate=200000

width=320

height=240

[v3]

type=video

bitrate=100000

width=160

height=120

[a1]

type=audio

bitrate=192000

[a2]

type=audio

bitrate=96000

[a3]

type=audio

bitrate=48000

There are some problems need you answer.

What is the difference about Dashcast and MP4Box?

If I trying to write an MPEG-DASH player for Android.

what tool I should use?

Trouble you.

Thanks.
