MPEG-DASH playback no audio output

[gang_zhu]

All

I put a mp4 media file to content folder, then check the playback using mpeg-dash and HLS , but there is no audio output when selecting mpeg-dash . At the same time, HLS playback is right, audio and video are correct.

MP4 file with h.264 video codec and aac audio codec

There is a error log:

HTTPStreamer/Properties boolean property mpegdashAdjustCTTSForFirstKeyFrameToZero to true WARNservercomment2017-03-1717:08:45-----439.775--------MediaReaderH264MPEGDash.indexFile[vod/definst/1vlc.mp4]: First frame of video has a non-zero CTTS value [80], playback may not work on all browsers, try setting HTTPStreamer/Properties boolean property mpegdashAdjustCTTSForFirstKeyFrameToZero to true

Hi Gang,

Have you tried setting the referenced property to true?

In order to enable this property, you’ll need to add the following to the

/// section of the [install-

dir]/conf/[Appliation]/Application.xml:

<Property> 
	<Name>mpegdashAdjustCTTSForFirstKeyFrameToZero</Name> 
	<Value>true</Value> 
	<Type>Boolean</Type>
</Property>

Regards,

Alex
