nook HD+
I've been trying to get some videos to work on it.
highest resolution video is 960x540.
Anything higher, even 720p, it will say, "we cannot play this video".
This is a huge disappointment. doesn't the hardware itself boast 1080p playback? So why this limitation?
It looks like the only way is to root it.
Yes, it can play 1080p w/o problem, in fact many of us even STREAM 1080p video off from a PC/NAS w/o problem. Most likely the culprit is the player/codec. I prefer and many have agree that BSplayer is probably so far the best video player on android.

I have found the culprit.
It turns out the nook is very sensitive to audio input.
Basically, it needs stereo AAC. Cannot take 5.1 anything. Cannot take MP3 either. Needs to be AAC.
instead of handbrake, you can just use avidmux to passthrough the video input and transcode the audio to stereo AAC. Even for MKV files.
Ithink 5.1 is fine. I never dowmgrade audio from 5.1 to stereo anyway.

Hi Diamond users,
CorePlayer Mobile 1.2.5 runs practically fine on the Diamond, using the Qualcomm TV graphics chip (QTv) in "TyTN II driver mode" (smooth zoom on and quality high).
Thing is that CorePlayer only performs good with video files with a not too high quality, so a quite low resolution and bitrate.
Only then you can have a good framerate.
Videos with a higher resolution, e.g. 640 x 480, the same as the display's resolution and a bitrate like 1200 kbps for MPEG4 video plays well, but the QTv chip has trouble keeping up the framerate, resulting in some small, but noticeable stuttering, especially when the 'camera moves' in videos.
Any tips on that, or do I just demand too much here.
Second: CorePlayer and A2DP.
When I have my Bluetooth A2DP headset on, CorePlayer (and/or the Diamond) starts to drop lots of frames, even on the lower quality movies that have a proper framerate when not using A2DP.
Is A2DP demanding that much resources that the Diamond/CorePlayer can't handle the framerate anymore?
This really bothers me, especially when I see the Nokia E90 (having hardware acceleration on graphics as well) running 800 x 352 MP4 movies at 1200 kbps with the full 25 or 30 fps framerate, without showing difference when using A2DP.
Is the Diamond that bad with graphics or is the Nokia E90 just that good?
Does anyone know if this can be enhanced by using some tricks?
Isn't there any way to improve the video fps when using A2DP?
Videos play fine, but just with A2DP on the fps drop.

Not to derail your thread but did you find a solution to get a smoother playback? as in removing the small noticable stuttering? it makes me crazy ;-)
what program and settings do you use to convert videos for the diamond?
A2DP is quite CPU intensive, so if in addition you have a high-res movie, you SHOULD expect it to stutter.

don't know why but everything is very smooth for me. maybe yr headphones are to blame, maybe yr ROM? am i lucky?
edit:
i have to correct myself. didn't try 640 x 480...my bad, apologies.
Hi
I am about to buy an optimus 2x, but before that i have to know once and for all-
does 720p mkv work with dice player/mxplayer with hardware decoding at least decently?
i sold my i9000 to replace it, how are the video capabilities of the 2X if you compare it to the i9000?
i'd appreciate a fast answer- the deal is supposed to be done tomorrow
thanks
The o2x can only hardware-decode a very limited number of 720p videos (some tv shows you "find" on the internet works, other do not, most movies lag), however with software decoding (for example with mx player) it can play another bunch of videos, still not all though. Do not buy this phone for it's video playback capabilities.

Guys.... this is wrong section for you...

Really?
Haven't had a problem yet.
720p with dolby digital (software audio decode mode), DTS (software decode mode).
MP4 with CABAC and 3+ ref frames, shouldn't be possible but it works fine and in hardware too.
HDMI output is clean and has no issues, even with 25ft cables.
Maybe I'm lucky, maybe ergoen wasn't...
I really haven't found a movie that I can't play, I even stream them from my PC/router by mounting the drives in cifs manager and playing them in either mx player or quick pic player.
640x480= 480p
Screen Res= 800x480
SD space=limited
Hardware mode seems to get better battery life,software decoding a 720p movie used around 95% battery over 2 hours with airplane mode on
Hardware decoding a 480p TV show used 25% in 50 minutes, airplane mode on.

I'm having troubles with stuttering when I'm trying to play 1080p blue ray content over HDMI. I have tried stock 2.3 and CM7 both with similar results. I noticed that when I overclock to 1.4ghz stuttering is less. My question is how is possible to play without stuttering?

to me it worked with no problem
i have a friend who works in a service shop who tested it for me
he tested on an LG TV
maybe it`s because of the TV?
i also put a video filmed with the phone on my Samsung TV worked ok also
Well I think "1080p Blue Ray" is too much.
I usually convert my vids to 720p mp4, it plays flawless that way. The phone is not a dedicated video player
O, wait, I'm assuming you're using the stock video player, no? Cause if you're not, that may be the issue.
Other players in the market use software decoding, while LG's stock use hardware decoding. Given LG has full access of the Tegra's code, it allows the player to make full use of the chipset's power.
i think i might know. it`s stuttering because the amount of data needed to be processed by the phone is too big. since you said it`s blue-ray.
also the vid is probably big. more than 8GB. since the standard format used by the phones is FAT. you probably converted it to NTFS or exFAT?
I've only been using the Chromecast for a day, but it seems the audio and video are getting out of sync after a while and the only way to get it back is to reboot it.

That's odd. If you play the same links on a computer, tablet or phone, does the audio stay in-sync?
Does it happen on all videos, or just certain ones or certain types?
Note that A/V sync drift can come from various sources:
In the source - this drift is actually present in the source. If you start playback, pause, then resume, it will still be out of sync, and will be out of sync by the same amount (unless introduced drift is also occurring). Jumping forward/back will also have things out of sync, though the amount might vary depending on the other factors below.
Encoding - since YouTube and other streaming services usually have to encode the source video to their streaming format, an error in the encoding can cause sync drift. Essentially it's the same problem as "In the source" except viewing the original source won't show the drift, because only the encoded versions have it. It's not an error per-se, but often times streaming encoding will not re-sync A/V mid-stream very often, which can lead to things being out of sync if you jump forward/back in the content rather than playing it all the way straight-through.
Introduced during playback - this drift is introduced by the playback or streaming, usually by the player, sometimes caused by audio resampling or other processing. In these cases the audio will start in sync then gradually fall out of sync as playback progresses. Pausing and resuming (not jumping forward/back) will usually re-sync the audio again, then it will gradually fall out of sync as playback continues.

The original source is in sync on the source and on my Roku and TiVo. If I reboot the Chromecast, the video and audio are in sync. It seems after you watch it for a while, the audio and video drift slightly out of sync. Switching between sources (YouTube vs Netflix) or stopping and starting the video does not bring it back into sync. Only a reboot corrects the issue.

Interesting. Definitely sounds like it's something to do with Chromecast's decoding.
You aren't using any sort of audio breakout or external stereo, are you?
Also, what firmware build is your Chromecast on? (Check the Chromecast app)

I am on 14651.
In my setup the TV outputs to a stereo via toslink. My TV is rather old, I bought it in 2008. But it works great and has HDMI, so there's no need to upgrade.

I have a TV of near the same vintage, just before Sony started supporting video over DLNA.
The only other troubleshooting step I can think of it to see if there's a difference between using the TV speakers and your external. I doubt there will be a difference, but there's a tiny possibility that perhaps there are too many samples being output somewhere, which would introduce increasing drift.

That's my next try.
I really like the Chromecast. Once is does Plex, the Roku may be up on eBay.

I love my Chromecast too, but until it gets WatchESPN, I still have a need for the Roku..lol

After updating to 14651 I met the same problem with you. But after a factory reset it works well now. I suggest you to do a factory reset and maybe it will work find like mine.
OOS can happen on the decoding side usually when the Video is at too high a bitrate for the device to handle....
The Audio takes nothing to decode but the higher the bitrate the longer it takes to decode and display the video.
Therefore the Audio comes ON TIME but the video gets delayed leaving you out of sync.
Does the audio PRECEDE the Video? (this is the most common form of OOS you see on the backend)
It usually only happens on the Encoding side when the Audio and Video take two different paths to the encoder.
Thats about the only time you might see Audio delayed compared to Video.
It is possible that the decoding device can get lost or face some memory condition that would cause this but usually it's because it attempted to decode some high Bitrate video in the first place.
I have been unable to find this issue online, which makes me think I am in a small minority that is experiencing it. I received my Gear VR, and it is a fun piece of equipment, though definitely not something I would have spent money on. I watched some Netflix and it played smoothly, though I saw pixels like people were saying. Nothing that can be done about that.
Here is where I experienced a problem. Oculus video says you can play your own videos from your library. It is true, however, I tried watching an hour long video last night and the video would periodically lag while the audio stayed on pace. As such, the audio got ahead of the video. I was able to remove the headset for a second, put it back on, and continue with everything synced again but it would continue to happen throughout the video. Has anyone experienced this, or know of a way to reduce lag so my videos on the device's drive can run smoothly? It was very annoying, and makes me think the Gear VR will become a paperweight if I cannot resolve this issue.
I found it works best with h.264 video and m4a audio, I had similar issues as you describe wirh AC3 audio.
I've seen that happen with *other* devices when a particular audio/video stream was more challenging to decode. I'd assume that using sub-optimal encoding for a video would give the Oculus Video significant "heartburn" in decoding.
If your source video isn't in-spec I'd consider transcoding it into most-compatible spec. That won't require any specific video transcoding tool, it's not a 3D specific process, and the tool of choice will depend upon what OS you run on your computer. For me under Linux I use AVEIDEMUX for this kind of work, generating an MP4 container with AAC 128Kbps audio and the h.264 video stream. I haven't watched a full movie in VR yet but those encodings have worked well for my previous devices (GS5, Galaxy Tab S 8.4, and Nexus 7 2012). It also works for playing 4K video smoothly off SD on my GS7.
