How do you check if a media file contain DTS-HD / DD TrueHD?

[tingshen]

i am not sure if mediainfo is able to show, but I have a media sample that's supposed to contain TrueHD tracks but mediainfo only showed AC3.....

[daniel_owen_uk]

Does it show the bitrate?

If it's a TS/M2TS open it with tsmuxer or tsremux.

here are some info from media files:

Looks like just regular DTS & DD to me.

Idem here

Mmm, mediainfo does not properly detect advanced streams i.m.o.

This is the info for an TrueHD EVO:

Audio stream #1 is in fact a 7.1 TrueHD stream...

I use RemuxTool to show me what is in the files.

[tingshen]

so seems like there is no way to check on the media unless we output the stream to a receiver/decoder to check?

[daniel_owen_uk]

Yeah could be, the first media info output has an audio out with no bitrate on, that could be a bit of a giveaway.

[tingshen]

what about LPCM tracks? would Mediainfo able to identify them?

[tingshen]

I am curious to know if A-100 able to output bitstream for TrueHD or DTS-HD ? So we can send the HDMI out to a TrueHD/DTS-HD AVR for decoding.

So far I only saw LPCM 2 channel via SPDIF....

No. Need HDMI 1.3a for that and A-100 only has 1.1

And that's all you'll get via SPDIF. You need HDMI for multi channel PCM on teh A-100.


SMOKED UP!!!!!!!!!!!!!!!!!!!
