I'm using AWS Elemental MediaConvert to transcode video files into MPEG-DASH (with DRM encryption).

The mpd files generated are having manifest profile urn:mpeg:dash:profile:isoff-main:2011. I have tried this with different system presets available for the video , but always ended up with same manifest profile. Some settings I used are:

Output group: DASH ISO with Segment control: SEGMENTED_FILES Output 1: Video Codec: MPEG-4 AVC (H.264), plus different combinations of all available settings.

Is there any thing I'm missing or any specific combination of these settings that can create an mpd with following profiles?

The media player we use supports only urn:mpeg:dash:profile:isoff-on-demand:2011 and urn:mpeg:dash:profile:isoff-live:2011 profiles.

Unfortunately, we cannot change the media player as it is shipped with the SDK from DRM provider.

Any help will be greatly appreciated.

In the DASH-ISO output group options set HbbTV Compliance as HBBTV 1.5. This should give you isoff-live manifest profile.

Please refer the attached image.

  • But the manifest profile is now `urn:hbbtv:dash:profile:isoff-live:2012,urn:mpeg:dash:profile:isoff-live:2011`, not `urn:mpeg:dash:profile:isoff-live:2011` or `urn:mpeg:dash:profile:isoff-on-demand:2011`. – akhilsp May 15 '19 at 12:00
  • Anyway, this works with my SDK player. Thanks again! – akhilsp May 15 '19 at 12:01

According to the documentation of AWS Elemental MediaConvert,

H264CodecProfile is allowed following types

BASELINE
HIGH
HIGH_10BIT
HIGH_422
HIGH_422_10BIT
MAIN

Is it possible to change the codec level to BASELINE and try?

When you say player doesn't support mpeg-dash profile urn:mpeg:dash:profile:isoff-main:2011 is it about the mpeg-dash profile or actually decoder doesn't support H264 main profile?

  • The player can play `.mpd` files with `urn:mpeg:dash:profile:isoff-on-demand:2011` profile. However, with the isoff-main profile, it is not working. – akhilsp May 14 '19 at 05:48
  • I've tried with BASELINE, but with no success. Resulted MPD looks like:`````` – akhilsp May 14 '19 at 09:10
