That's an awfully big assumption.

What happens if you rip the main movie to ISO with DVDShrink or something similar and try and play it that way?

Perhaps, but that is what a lot of the media players that don't support navigation do so I don't know why XBMC would do it any different (look inside the ISO find the largest VOB and play it). In either case, I'll have to do a little experimentation and see if that resolves the issue. However, I can't say that that would be an elegant way of handling the issue, after-all the reason most people bought the licences to begin with was so they didn't have trans-code or rebuild their media library... re-ripping over 800 DVDs to strip-out navigation is simply not an efficient/acceptable solution for most people.

P.S. It would seem that a lot of people are reporting the issue over at raspbmc (I'm running raspbmc) so it could just be an issue with their builds, they may have disabled the functionality because at the time MPEG2 was just a dream. Would be interesting to know if this is affecting people running OpenELEC for the Pi...

DVD ISO support is disabled in OMXPlayer and no subject to change at the moment. ISO support has a quite low priority on my todolist.

I tried a 1080p movie with DTS yesterday, but I'm getting a lot of artifacts in the picture? I'm not sure if this is due to lacking hardware, XBMC or software configuration? Do you have an idea were I should look Gimli?

it must be the video profile, like too many reference frames (it should be max. 4 at 1080p Level4.1)

Only a single movie or more movies ?

[email protected] 1080p with 9 frames, ponk as out of spec.

So the video is encoded with too much reference frames? And the PI's VPU isn't strong enough to deal with it? (Since the files play perfectly on my PC/Mele A2000).


RE: Raspberry Pi [HTPC] - Wonder if this will work out for XBMC?? - davilla - 2012-08-27

strength has no bearing on this issue, it is the ability to handle out-of-spec h264 video.

If you're trying to downmix the DTS audio that will cause a studder




RE: Raspberry Pi [HTPC] - Wonder if this will work out for XBMC?? - Nu7s - 2012-08-27

Do I have any other option then to re-encode these files with fewer re-frames?

No worries Gimli, most of us here know how much you've done for the community here and that you're a busy fellow.
Thanks for the official commentary.

Cheers,

Isn't enough for dts downmix?

Nope, passthrough, overclock may help. There's talk of hardware decoding in the future.

Could you please take a look on MS VC-1 with codec_id_wmv3 issue? Here is the original thread: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=24&t=15684 Thank you.

I hope you find someday the time to enable this. Lot of my movies are in ISO and searching the net for a solution a lot of other people trying to find a solution for it also. So it is definitely not a waste of your time.
Keep up the good work and thanks for all you have done already.
