Does HDCP affect performance in games?

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.
HDMI 1.3 incorporates a function to allow the tv remote to control other hdmi units, called regza link in my toshiba tv, but most manufacturers have their own (semi-compatible) versions.
From what i understand from the tech specs, the optimus x2 does have HDMI 1.3, so i wonder, can i use the tv remote as phone remote and effectively turn the phone into fullHD home theatre system?
i havent yet gotten the phone, and i probably wont get a hdmi cable with it, so i cannot test it myself for several weeks (living on the countryside, miles from nearest electronics store..
No you cant
firstly it doesnt have any implementation of HDMI CEC (doesnt have to just because it have HDMI 1.3),
secondly its not a mediaplayer but a phone running a phone OS - the OS are not designed to operate as a remote controlled mediaplayer using HDMI CEC control or otherwise - and there are no "mediacenter software" you can install to make it act like one.
thirdly its not a mediaplayer but a phone - its ability to play media are limited to certain formats and certain encoding profiles. "1080p" or "FullHD" are not terms describing its ability to function as home theatre system, but simply and only a term for the maximum resolution supported of the supported file and encoding formats. The phone doesnt support all the media formats and variations you would expect from a home theatre system or mediaplayer. Its "1080p" abilities is about being able to play limited Web2 content like youtube video, encoded in baseline profiles - it doesnt have support for encodings in main or high profiles or AC3/DD or DTS audio or mkv or DVD structures or BD structures or HDTV or subtitles or anything else you would expect of a home theatre system
Its HDMI connection is about being able to project the odd pictures and video now and then, but it require video to be encoded in a supported format within the supported specs and it require the control to be done on the phone.
It will never be any kind of FullHD home theatre or mediaplayer replacement.
I'll say it it a bit nicer.
The HDMI connection is excellent for playing video you have recorded on your phone or to use the phone for playing correctly encoded video if you are away at a hotel for the weekend.
Using this phone to play full HD movies as a home theater replacement is never going to happen but clearly the ability for phones to act as a full media server is in the post.
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.
If you have Netflix, this is a way to check your Chromecast's throughput.
Unlike a simple Internet speed test (which tests the throughput from some Internet server to your router), this test helps diagnose Chromecast's throughput, which is limited by its WiFi signal reception.
Play this video:
http://www.netflix.com/WiMovie/70136810
You should start the video fresh when changing conditions - resuming from pause doesn't always seem to increase the rate.
Throughput Diagnostics:
The bitrate and resolution will gradually rise during playback.
Under ideal conditions (excellent WiFi signal and adequate Internet bandwidth) you should be getting a bitrate of 5800 at 1920x1080 resolution on Chromecast.
Oddly enough, my desktop computer gets bitrate 3000 at 1280x720 resolution on a powerline connection. I'm not sure why it's limited, it should be able to do higher bitrate and 1080p. YouTube seems to prefer 720p over 1080p on this machine as well, so might have something to do with ping times or something. *shrug*
If the video buffers or the bitrate remains consistently low on Chromecast and you know it's not your Internet speed holding things back, then your Chromecast's throughput is being limited by your WiFi. Probably Chromecast has poor reception - try the HDMI extender and/or repositioning or reorienting your router.
TV/Sound diagnostics:
From the 8:40 mark there are good test patterns to help diagnose aspect ratio and overscan issues that you might be having with your TV too.
The large white circle should be circular (tilt your head to check)
On the grid with circles should, the corner circles should touch the edges of the screen but not be cut off. If they're cut off, your TV is performing Overscan or is not in 1:1 pixel mode (if it's a 1080p TV).
The subtitles also seem to imply there are some subtitle font/color changes and multichannel audio tests, but I only have 2.1 sound so I can't tell, and all my subtitles are fixed-size and yellow (probably the Netflix Chromecast app doesn't support the different subtitle formats yet).
I think because you were using chrome browser to streaming this content.
Because of security reason, the limitation of bitrate is set to 3000. if you are using safari you could reach 5800.
