Hi, we have a dm8000hd and went to play a film lastnight which wouldn't work and finally the above error appeared. We searched through our entire system plugins ect and couldn't see anything related to gstreamer which we find a bit odd since we've not had this issue before and I'm sure we have/had gstreamer installed. What do I have to do o make this work? :/

Check which codecs are used for audio and video. You can use mediainfo or e.g. vlc.

And where does the error occur? In the e2 log? If yes, please post the hole log.

This is the codec information from VLC on the PC

 

Stream 1

      type:audio

      codec: TrueHD Audio (trhd)

      language:English

      Channels: 3F2R/LFE

      sample rate: 48000 Hz

      Bits per sample: 32

DM8000HD OpenPLI Latest Nightly Build

[betacentauri]

And which video codec? Or was it only a sound issue?

TrueHD codec might be a problem. I think trueHD don't works on my et9200 and I don't know if your dream supports it.

[betacentauri]

Here is a gstreamer patch to enable TrueHd support in matroska files. It's fully tested with OpenPli3. And I have also checked that it don't breaks OpenPli 4 builds.

 

To playback TrueHd it seems to be necessary to install gst-ffmpeg and dependencies(libav,...) for it.

So after OpenPli has applyied the patch you need to install the libraries. Here is a description (it's the same as for alac):

A little warning:

I found only 2 testfiles. Sounds and video plays fine, but with these 2 files CPU load is quite high >80% (et9200).

You can find samples here http://www.demo-world.eu/trailers/

Website does only have m2ts files with TrueHd. No mkv. And m2ts files are not processed by gstreamer. I didn't test, but I guess TrueHd won't work for them.

[pieterg]

you can test m2ts with gst-launch I guess

[betacentauri]

Yes, I know. I tried it once with other files(other codecs and it didn't work).

But here mkv was the problem(I guess). I could reproduce the problem and my patch solves it.
@pieterg: Can you commit the patch?
And do you have time to look at this? http://openpli.org/f...ndpost&p=368331
Or did you already look at it?

[pieterg]

I've pushed it to the upstream branch (4)

[betacentauri]

Thanks!

I am renaming them to .mkv and then gstreamer handles those files. It worth trying.

Tried the telnet patch etc but its not working. Does the box need a reboot?

Yes its an Mkv file we are trying to play just for the record.

Went through the process again and pasted the Telnet Screen.

Pieterg has only committed my patch in OpenPli 4. So when you use OpenPli 3 it unfortunately won't work. So you need to build your own image or switch to OpenPli 4 or
@pieterg: Can you also commit it in OpenPli 3?

[JessaJ]

_{Open Pli 4 it is then}

[JessaJ]

I cant FTP into the box on OpenPLi 4, any know problems? Using Root & dreambox as normal.

[betacentauri]

There are several threads about it. Login via telnet and execute passwd. You can set the same password again. Afterwards FTP should work.

[JessaJ]

Many thanks, I am into it now

[JessaJ]

Done it all again on 4.0 and its still not decoding the True HD soundtrack.
