Is 60-70% CPU load even while using the CrystalHD expected?

Sounds about right for a single core Atom [email protected] with a 1080p mov. Most of this is moving the decoded picture frame around and audio decoding. Considering that this video would cause your single core Atom to roll over and die if you tried software decoding, this is pretty good

Depending on video content, I see anywhere from mid 20s to 50-60 percent on the AppleTV under ubuntu 8.04.

I have some trouble getting vesafb to work on karmic. Anyone mind sharing how they got it oing?

Pretty good my a$$, this is bloody brilliant!!!

I'm going to try using the audio delay setting in the OSD tonight to get the audio and video in sync, will post back if it doesn't help or if I see anything else wrong.

If you can qualify the audio delay that would help. Always the same? Depends on audio codec ? Depends on video content ? MediaInfo can be used to dump all the info from a video file.

Anything that would help narrow down the cause. Also, check a/v sync ( type 'o' to pop up the codec OSD). It should be close to zero.

Davilla, are you saying you don't have any audio sync problems?

Both myself and waterhead (on AVSForum, see this thread, I'm tux99 there: http://www.avsforum.com/avs-vb/showthrea...st17991088 ) see it too, it can be anything from 0.5 to 2-3 seconds, that the video lags behind the sound.

I imagine that this is due to having to send the video to the crystalhd, get it decoded and receive it back, before displaying it, but I hope there is a solution. Adjusting audio delay in XBMC works, but it needs readjusting for every movie and also after any chapter jump or ffwd or rewind it changes again.

I'm using a D945GSEJT mobo (mobile Atom N270 single core, like in netbooks) and waterhead is using a netbook (also with N270 Atom). My cpu load is not excessive, I see 45% load with top during 1080p BD backup playback.

I thought you were aware of this audio sync issue and it was just one of the things you hadn't gotten round to fix yet, but if you are not and need further details I can provide you with a debug log, let me know if you need it.

Davilla, are you saying you don't have any audio sync problems?

Most are in sync, VC1 in a m2ts are not, they were in sync in the past, grrr. That's under my setup. Others' have different setups. Since I don't have an A/V receiver, I run around in analog out downmix or digital out also downmixed.

I'm asking for details here, play a video, note the audio offset. Is it the same all the time for this video? Play it multiple times, seek, etc. Is the offset the same? Note the video and audio details with MediaInfo. Rinse/Repeat with another video file. Same or different behavior ?

If video is lagging audio and is in slow motion and xbmc.log shows frame drops like crazy, that's a different problem.

[pfennig]

My audio seems to be about 0.3 - 0.4 seconds ahead of the video on the HD movie I tried (m2ts Quantum of Solace). Simply using the Audio Delay (or was it "Audio Offset") setting in the OSD fixed the problem however - it stayed in sync within the scene I watched, and seemed to be fine after fast forwarding about 10 minutes as well.

Another movie I tried looked better without any adjustment (though it was a dubbed mkv anime, so lip-sync isn't expected to be perfect anyway).

For now, I'd consider this a minor issue as it is fixable with the OSD settings. It would be nice not to have to spend 3-4 mins per movie getting the value just right however, so I'd mark this as something to revisit in the future for the 'final polish'.

ion_man said "after any chapter jump or ffwd or rewind it changes again" - I didn't see that, but if the case then this would be a more severe issue warranting a closer look.

Edit:
The QoS m2ts 1080p that I tested needed sound delayed by about 0.35 seconds. Seemed to stay consistent, but I didn't stop/start it multiple times last night, just got it in sync once and then FFed 10 mins or so and checked that it was still in sync. Then watched something else :-)

I dont have a usb s/pdif thingie yet, so I am also using audio downmixed to analog stereo out, if that makes a difference.
Video is smooth after initial startup, no framedrops on this one (I do have other samples that do framedrop a bit, I'll have to track those down and post mediainfo details)

Davilla, I'll get back to you with more precise details and mediainfo output later (or tomorrow if I don't find the time for it later today), I'll build the latest svn first to test it with the latest code.

[ion_man]

Ok, did some testing with svn27420 just now and it appears the lip-sync issues I had with previous svn builds from a week or 2 ago, are gone!

I noticed though that some BD backups that used to play fine before (other than the lip-sync issues) now play at very low fps, instead of 24fps the following plays at 15-19 fps:

I guess the fact that the last one plays fine should mean that CrystalHD decoding in XBMC is working on my system, what's weird is why isn't it working for the other 2 files (and it was working for them with older svns too)?

(had to split post in two due to 10K limit per post on this forum)

[davilla]

The following plays audio only, the video stays stuck on the XBMC menu (this used to play fine before:

VC1 in a mkv, oh goody. You say this played fine before, which svn version ?

I'd like a 50-100MB sample of this.

[ion_man]

VC1 in a mkv, oh goody. You say this played fine before, which svn version ?

I'd like a 50-100MB sample of this.

It was svn27068, I just reinstalled it (I always build packages so I can switch between them easily) and I remembered wrong that VC1-MKV still plays only audio, the picture is stuck on the menu even with svn27068.

But the original M2TS that this MKV is made from plays fine (both with svn27068 and svn27420).
How come VC1 in a M2TS works but not in a MKV? (the video stream is identical, I haven't done any transcoding , only re-muxed from M2TS container to MKV container with Makemkv).

I can try to make a short sample of the VC1-MKV, but I have to find a Linux tool to do that (I don't have Windows at all at home).

It would be great if VC1 in MKV would work too, as I prefer remuxing to MKV, since chapters only work with MKV and I can eliminate all audio and subtitle tracks that I don't need.

But I noticed that with svn27068 the movie1.mkv I listed above plays fine at 24fps (with only slight oscillation between 23.x and 24.x) while with svn27420 it only plays at 15-19 fps as stated previously, so this is definitely a regression.

How come VC1 in a M2TS works but not in a MKV? (the video stream is identical, I haven't done any transcoding , only re-muxed from M2TS container to MKV container with Makemkv).

I can try to make a short sample of the VC1-MKV, but I have to find a Linux tool to do that (I don't have Windows at all at home).

It would be great if VC1 in MKV would work too, as I prefer remuxing to MKV, since chapters only work with MKV and I can eliminate all audio and subtitle tracks that I don't need.

But I noticed that with svn27068 the movie1.mkv I listed above plays fine at 24fps (with only slight oscillation between 23.x and 24.x) while with svn27420 it only plays at 15-19 fps as stated previously, so this is definitely a regression.

use dd to chop a sample from the beginning.

as for why vc1 in m2ts plays while vc1 in mkv does not, welcome to container parsing games.

I have sent you the link to the sample file via PM.

Do you need a sample of that AVC mkv that plays only at 15-19fps too, or do you already know what the problem with that one is?
