can I create a virtual "fake" camera? (/dev/msm_camera/*? - Desire HD Q&A, Help & Troubleshooting

Hi all!
I'm currently working on a project about latencies in image and video transmission.
my question is:
Do I have the ability to simulate a camera image or video on real hardware?
i through about a link (assuming root) something like:
ln -s /sdcard/image.jpg /dev/msm_camera/msm_camera0
or feed the real cam with a stream or a picture.
Is this possible?
kind regards!

Sounds interesting but what are you going to use it for?

>Sounds interesting but what are you going to use it for?
to send the same test picture all the time (over skype video-chat for example). on desktop we send DataMatrixCodes which is
recognized form the receiver

Ah ok but I have no idea how to do this tought.

I also am curious how you would do this, people do this on the computer all the timedo if you've seen how they do it on chatroullette sometimes

Using EVO as a nursery monitor

Any suggestions on how to use the EVO to watch what's going on with our babies in their nursery if I put a web cam or some other sort of video camera in there? Preferably a very cost effective solution and one that will allow me to move the camera to a different room if necessary.
There are apps in the market for this.
Thanks, which one with what hardware do you recommend?

what about QIK? it allows you do stream live videos on the internet, so you can log into a qik account via a pc and see what is going on through your Evo 4g....
correct me if I'm wrong on this

I want to watch using the EVO. I'm sure you could do that very easily but that would be an incredible waste of resources.
Probably an X10 camera or similar. Check out smarthome.com
I wonder if my logitech wilife indoor security system would work with this....
Linksys IP webcam for hardware and IP cam viewer lite from the market is my setup.

[Request] Screen to TV via DLNA. possible???

Ok so since our TV out doesn't work, is it possible to create an app that uses DLNA to put the Epic screen onto the TV or Computer?
I don't know much at all about formats and conversions, and am generally confused about the complexity in that area, but this doesn't seem too hard an idea to create.
Can it even be done for my computer? use the DLNA/wireless to put my laptop screen on my tv?
Don't think so.
DLNA servers usually just serve up files to a DLNA client. It doesn't change the file in anyway. To sum it up in short - it streams the actual file as if you were reading it locally, but only the file itself - not the output of the file.
Example, if I have an MKV video file hosted on my DLNA server (my PC), my DLNA client on my PlayStation 3 can't play it since it doesn't support MKV even though my PC does.
Think of DLNA as a way to file share content from your phone to your DLNA capable TV. What it does not do is export your mobile screen to your TV.
DLNA stream
I have been doing some testing on my DHD and it seems that its the phone that streams the content through DLNA to the TV. If there was a way to convert the mobile screen output to video stream there might yet be hope.
... Allshare? Anyone? No? Ooookay.

Allshare thats native is a tad "picky"
Twonky Server mobile(the free one not the pay) in the market however shares files beautifully to DLNA enabled devices.
But as states it's ONLY for sharing files, even with hdmi out you're only gonna get what it wnats, unlike a dsektop where it displays the desktop.
if you wanted to do it find a remote client that lets you "RDP" to the phone and have a computer hooked to the big screen.
theres really no advantage to displaying the desktop of the phone in this way. Can't see why it would even be an option.(or why anyone would want it)
Yes

In linux(X11) i think it could be pretty straight forward, since you should be able to point the dlna TV to a file created by x11 with the output of the screen.. I dont know how the screen capture process is in android, and not at all in windows, but it is possible, though performance may suffer.. Im want to write an app for android with this, but i wont right it atm.

One X to push video to other DLNA devices (theory)

Hello this is just an idea and I hope someone could comeup with something to do this. Now I know that you can install other 3rd Party apps but I like the idea of the three finger swipe and your video popping up on your DLNA capable smart tv or computer client, but after some googling around I couldn't find anything.
So I was hoping I could give someone the idea to create something like this that would trick the phone into sending data to another device than the MediaLink from HTC. Although if I haven't searched around enough and have missed something please could someone point me into the right direction.
Thank you very much
Steven
i dont think it "sends" it merely streams them

Yeah, thats what I meant!
The One X does support DLNA and the music, photo and video apps have a play on function so you can stream to any DLNA device. This principle works fine for my WDTV. Just no gesture which isn't a big deal really.

Flash/video player orientation

I don't know if it bothers anyone else but who came up with the idea of having charging port on the side?
It makes virtually impossible to watch videos fullscreen while the phone is plugged as usually I need to lean it against something and watch with other people. I could just turn the phone around to have the port on the top but the fullscreen videos doesn't turn around as full screen always flip to the right.
Never had problems with my Desire HD as it has charging port at the bottom which is the best place I think as you can turn the phone around with no problems ;p
Is there any way to turn around flash videos?

I just turn it to the left so that the power is at the top, I'm on a custom rom

Yeah it works with YouTube designated app as it rotates every way, but it doesn't rotate for anything else, like when I'm trying to watch the Olympics of BBC website or any other streaming video from different websites.

I use tv catchup it rotates both ways http://static.tvcatchup.com/android/TVC_0_40.apk
Sent from my HTC One X using xda premium
flash only allows one way rotation (to one horizontal side not the other) however if you just zoom the webpage so the video fits into it perfectly, then the internet browsers rotational controls will come into play, and should let you rotate all ways.
theres also some apps on market that will allow you to force orientation as well
I've just got this phone today and found this problem irritating as hell as soon as I plugged it in at home, but I've found an app on the market which solves this issue called "Ultimate Rotation Control" by "FaMe IT" (sorry can't post the link as I'm a new user) it's only a 7 day trial version and full version costs £1.69 but it's better than nothing. If anyone has a free alternative please let me know!

Screencast?

Is there any way to do a screencast on an Android device... in particular the Nexus 7? I'm trying to put together a video and I wanted a clip that showed the U.S. and it zoomed into a specific city. Problem is, on the computer Google Earth is somewhat choppy despite having nearly brand new hardware, and Google Maps just does an instant snap to that location. Google Maps on my N7 on the other hand works JUST AS I WOULD LIKE... but I'm not sure how to capture it?
Any idea?

Screencast captures your phone screen at high frame rates into a high quality MPEG4 video with audio. It can also take snapshots of your screen by holding the search key on your phone.

I want something like this, not to record a screencast, but to use as a way of having video out in lieu of not having hdmi. I have a pc hooked up to my hdmi display and was looking at the options. This app sounds like the best but doesn't work yet with tegra 2/3.
How fast is it with other devices? Like could a game be played at a smooth frame rate? Does it allow to stream live and not record a video?
Are there any other ways of doing this?
I've been searching for a while now with no luck. I record gameplay on my GNote with the afore mentioned app but seeing as the developer has all but vanished I'm guessing we won't be seeing Tetra support.
You'd almost think Nvidia would make an app to do this just so Tetra fans could make gameplay videos, thereby promoting their devices.

There are some demo videos of stuff coming... Nivdia has one showing a playbook to a TV that has the Miracast protocol
and ESR labs has the following
Hopefully soon...
Unless you already have a TV with it built in, you will need a some some sort dongle that has WiFi and s HDMI output. I just got a raspberry pi to be used with the ESR labs Android Transporter when it come available.

I just stumbled upon those videos yesterday. Very interesting stuff. I think I may grab a couple of raspberry pi's. I'm in Canada and I couldn't find it in stock right now. I wish they would build a cheap enclosure for it. I put a post on their website if they plan on making a linux client and not just for the pi. I would think it wouldn't take too much to make a generic version. I also noticed some hdmi outputs on tablets don't provide 1:1 mirroring. For ex, acer tablets cutoff the bottom menu. This I believe is for video playback, which makes sense, but I hope it's an option or in the spec of miracast to offer 1:1. I saw a TI demo of miracast as well, and they make mention of the display showing one thing and the tablet showing something different typical of normal wired hdmi outputs. Nvidia also has demo's of miracast as you linked, but I hope they make a windows client. It'll be a ways off before it's standard on TV's and it sounds like there will be dongle's available, but a lot of people have computers hooked up to their displays so it would be nice if there is a complete software solution as well.
Android Transporter for the Nexus7 and Raspberry PI
Hi all,
the video you showed in the one post is our old demo video.
Since yesterday we have a public preview. please see http://esrlabs.com/android-transporter-for-the-nexus-7-and-the-raspberry-pi/

Is it possible without rooting and without PC? :crying:

No, it's not possible. you need root or a pc (actually the root way to do it does not work atm)
Android 4.2 is supposed to include native support for Miracast devices. So we just need the Miracast set top boxes.
Does anyone know if Miracast carries over Audio?
I just installed Screencast on my N7 with CM10.1 grouper nightly 12182012.
When I try to screen capture video in landscape or in portrait the audio saves properly, but the video is a static hodgepodge of TWRP Touch recovery in a purplish sepiatone
yo b1LL did you bother reading Screencast app description? doesnt support Nexus 7 nor any tegra 3 based devices
Here's one
There's another thread that has one, and it works for screencasting but it really only gets 1-2 fps. So if you're desperate:
