TrueHD fallout

Ok, success! I created TrueHD+AC3 track and remuxed everything with TsMuxer in BDMV folder structure. And now it streams over same network without problems!

So - the conclusion would be:
Same video and TrueHD audio streams fine in BDMV but doesn't in mkv.
I also tried remuxing again in mkv to see if maybe the original container was faulty, but no luck - still stutters like hell...
Something really is broken in mkv+TrueHD playback over network. Not a big deal since I can use folder structure, but still, maybe it's worth taking a look at firmware wise...

Thanks again mate for heads up about tsmuxer and truehd!

[jj666]

No problem, glad to help :-)

Cheers,

There are many audio fallouts during the movie. And sometimes the center channel disappears and only the surrounds work. This fallouts also affected the video as it caused the video to stutter as well.

This is the first time in a very long time that I have been having problems with my PCH A200

So , Is the TrueHD firmware support for my player (A200) flawless at this stage???? Or I should just transcode it to DTS-HDMA instead as the latter is having no major issue for the past 6 months already. In short, Is there any problem regarding TrueHD as of the moment/present firmware (I am using the may 27, 2011 firmware hence the latest) ????

Hope somebody can help

Cheers.

I don't understand why you would want to remux into a mkv container or re-encode the audio to dts-ma? the popcornhours have always done a flawless job of playing raw m2ts files right from bluray disks. there is no need to change the container. You can use "ToNMT" to remux out the extra audio tracks if you wish to make it smaller and it will still result in a ts or m2ts file that will always play flawlessly on your popcornhour.

transformers3 m2ts file plays just fine from a plain old samba share on my network just like countless hundreds of other bluray m2ts files have.

[joshwachubby]

hmm Lets just say I have no control whether or not it would be in m2ts or mkv

[joshwachubby]

Confirmed. Mkv plus highbitrate movie with TrueHD via network streaming is problematic

In support for such. I tried the following :

1.) Transcoding from TrueHD to DTS-MA, still in mkv container = NO PROBLEM;
2.) Changed container to .m2ts format, using the transcoded DTS-MA = NO PROBLEM;
3.) Changed container to .m2ts using the original TrueHD audio = NO PROBLEM.
4.) Changed container to .mkv using the original TrueHD audio = PROBLEMATIC, Stuttering, Audio Fallout.

Its kinda sad since the support for mkv containers is much greater than m2ts. Another downside with m2ts is that it does not support chapters itself, it needs a bluray structure using tsmuxer. Hope this will be taken into consideration. I really think its a problem with the manner the PCH acts or reacts with TrueHD.

Thanks.

If you want the max out of the 200 series, I recommend using the blu-ray structure.

Please realize that the Sigma SOC is designed for blu-ray playback in the first place.

PCH has done a good job by adding support for file playback. But it still has some limitations.

Kinda hard for me to confirm as I use MKV with TrueHD tracks during every beta testing round. The MKV I use are created straight from the BDMV/BD ISO using MakeMKV so there's no compression done at all.

I don't use any other program except AnyDVD HD, MakeMKV and MKVtools as I am a mac user.

For me, the toughest file to stream is BD ISO and I have loads of that in my tests. Beta testers know I keep an eye out for BDMV/BD ISO performance because I like to keep 1:1 backups of BD's I purchase.

I stream them from A200 to C200 and vice versa.

My test MKVs includes both BD ISO of Forrest Gump & Dances with Wolves. Both are highly regarding in terms of PQ and HD Audio quality in bluray.com's review.

I am having the same issue with Transformers 3. I want to try to replicate your findings. What tool are you using to transvcode from TrueHD to DTS-HD?

[Martien]

For all mkv fanboys I like you to read the specifications on the Sigma website:

This is the video decoding part: See the footnote.

Code:

• MPEG -2 MP@HL
• MPEG -4.2 ASP@L5 (up to HD, 1-point GMC)
• AVS Jizhun profile@L2.0, 4.0, 6.0**
• DV (IEC 61834 and SMPTE 314M)
• RMVB v9, v10
• 3D video support
- Generic side-by-side and topbottom output

dts master suite. You need to use eac3to also. Just backread, jj666 explained some stuff regarding eac3to

Just wonderin if the stronger and faster a-300 would do a better job handling truehd in mkv. If thats the case then I would definitely buy the new a-300

[Mr.Blackkatt]

Having the same issue just now. And my network is fine. My network monitor shows around 3MB/s output at max wile it support 100MB/s.

The Movie is Kung Fu Panda 2, with trueHD. I was just about to past info from "mediaInfo" as the movie was overwritten. But it had a bitrate very close to the Transformers movie posted here. This is also in a MKV container.

For me it feels like the PCH C-200 cant handle both the high video and audio bitrate.

[megalive]

blackkatt please make a new topic ... (or a moderator split it off)

But a few questions

is it an MKV file with trueHD ?
does the MKV file also had the normal dolby digital track ?
do you have an receiver which can handle trueHD ?
do you use HDMI cable too your receiver ?

your movie requires 15 megabits / second which means 3 megabyte should be plenty.

do you use NFS or CIFS ?

di you try too play the movie from a local disc in your C200 ?

I have no drive or hdd in my C200, only USB stick.
