Record HDMI?

Is there some way to record the HDMI output of the screen?

... but anything that's being fed through HDMI is also on the tablet. This is a little confusing. If it were an HDMI INPUT i could imagine the desire to record, but what exactly are you displaying on an external display that you'd need to record?

Yes and I'm asking if how to record that (like they can on the IPad)

It's easy. Why do you want to record your hdmi output of the screen?

Easy like? How?
Why... I can think of two reasons to do it, first if you are a developer the video of your app can be pretty awesome recorded that way, and after editing you get a nice trailer that will make people buy it. The other one is doing video reviews.
From my point of view it's NOT easy: you need an HDMI video capture device and a computer fast enough to handle the massive flow of uncompressed video... maybe the computer part isn't as difficult as it might seem, however the whole HDMI capture device will be around 200 bucks.

You could just get a screen capture app. I don't know of any off the top of my head, but you don't need to capture HDMI....you just need to capture what is being displayed on the tablet screen.

Hm, I see Hauppauge Colossus card has HDMI input - its unencrypted signals of course, but I don't know if the TF101 outputs encrypted or not?

Uhm, nice price. Not full hd, but especially if it's for 720p that could be a good choice... still I have to admit I'm not sure about the kind of output from the Transformer. My guess is that it's encrypted to allow viewing of protected content... but it's just a guess.

You'd think the tablet could switch to protected if it was showing protected content, but i fear you are right.

- YouTube: Asus Transformer HDMI Screen Capture
- YouTube: ..and the accompanying HowTo
Many these will help - the first one has some suggested capture cards in the flaffle
..also be aware of HDCP before parting with any hard cash!
Note: HDMI out reported not working with Google Video

Yeah, we need a capture card, we already got that.
And if that first video is to be believe the transformer is outputting encrypted rubbish.

The whole idea behind HDMI is to prevent digital copying. A compromise by the major studios mandated before they would release their HD digital content

False. The idea behind HDMI is to transmit high resolution imagery in a digital format.
Copy prevention CAN be employed, but it doesn't have to be.
(and of course if the sole purpose is to make a copy of some copyrighted material that will always happen, all it takes is ONE person to succeed then it spreads like wildfire)

The resolution the TF101 outputs to the TV is exactly the same as the resolution of the screen (save the 80pixel on the bottom) making the HDMI out 1280x720. If you record the stuff screen, it should suffice quality-wise.

Isn't it HDCP that is meant to prevent digital copying? And I believe HDCP is the reason why Panasonic LCD TVs are unable to show the output of the TF - am I wrong?

Sorry, I was typing that at 2 AM. If you record the stuff on the screen, it will be the same if not better quality than using a Capture Card to record the HDMI out simply because they're both 720p but recording the screen will not record the extra grain that resulted as interference when transmitting signal out of the mini-HDMI port.

I can't speak to the Hauppauge card specifically, but I own a Blackmagic Intensity Shuttle, which captures HDMI just fine on other devices at up to 1080i / 1080p, and it won't work with the Transformer.

Yes, HDCP is the "High-bandwidth Digital Content Protection" whereas HDMI is simply the "High-Definition Multimedia Interface "

So the conclusion is, you can't record the screen?

TF101 as a citrix thin client

I have gotten a TF101 to test it out as a supplementary mobile client.
We are running Citrix and I have a desktop published throug Citrix Receiver. I have found keyboard and mouse that works with this wonderful machine but I want to have an external display also.
But I find the HDMI support quite bad. The content fills more than the TV Screen and I cannot change the screen resolution. I would like to have a larger screen resolution on the external display but cannot find any way to do this.
I have a LG Optimus 3D phone and on that I can adjust a lot of options on the HDMI port so it should be possible.
One snag: I am testing out this to be used in large scale for hundreds and eventually thousands of users so this needs to be working on completely stock operating system.

Maybe the Asus HDMI to VGA Adaptor is something to think about?

Ok. I got this one and it almost fills my need. I need to get a higher screen resolution on the external display. 1280x720 is way to small for a permanent workstation. At least with the tools I use.
Maybe I just have to wait for ICS to get this working?

Are you trying HDMI on a TV or a monitor? If a TV does it look washed out and a little zoomed in? TV's have some over scan options that really mess with the signal from PCs. Look around the menu options of the TV and see if you can turn it off, alot of em can't tho. Just google HDMI PC overscan and you'll get a better picutre of what I'm talking about.
For res I don't think it can do better than 720 and I've never seen any options for it. I'd call up Asus if your going to be making a decision that could mean eventually thousands of sales for them.
Also don't forget that they said they're launching the Windows 8 Transformer this year. That should suit your needs beautifully.

How are you accessing your Citrix Desktop? Using the Receiver? Or is there another app specifically for Citrix Desktop access?
EDIT: Never mind, the VDI i was trying to access was taken down recently by the systems team. Do'h. Time to build a server.

Me personally I've been using the citrix beta app, seems to work better.

I tried with the VGA adapter on my 22" samsung syncmaster and the desktop filled the screen perfectly. Via HDMI to my 42 inch HDTV I got overscan problems.
It is though the monitor I need to use to acheive my goal of using it as a citrix thin client. I hope we can manipulate the HDMI output more in ICS. It would be nice to use the monitor's native resolution (1680x1050).

Agreed. It has more options and seems more stable. Go figure.

The TF101 does not support greater than 720p output for mirroring. No word from Asus if they will ever bump it up to 1080p capability, since the Tegra 2 already struggles with 1080p video playback. You should wait for the TF700T for full 1080p output.

Actually 1080p is not what I need. 1280 is more than enough horisontal resolution, but 720 vertical is too little. If it could output 1280x1024 on an external monitor I'd be very happy.
What I say is that there should be an alternative to mirroring on the HDMI port. With the dock and usb ports the interal screen could be switched off and a resolution of choice be shown on the HDMI-connected display.

720p mkvs and ICS

so i was hoping that ICS would fix all the mkv issues since on my galaxy nexus every mkv i have plays perfectly.
but sadly that is not the case. MX and BS players are the best and only lag when theres a lot of things going on, like the final battle in thor.
anyway, my mkvs are all that high baseband or whatever, and i haven't bothered redoing them, or trying to convert them because i was hoping that ICS would actually allow them to play.
now that it hasn't, i guess it's finally time to convert them all so i can play them.
so i'm asking for help for a program that will allow me to convert all of these so that they can actually play on the transformer, but without any loss of quality, or any increase in file size. currently they're all around 7GB.

Use DicePlayer, supports hardware decode
Sent from Galaxy Nexus (GSM)

@curti: not sure if that will do what i want, but i'll give it a shot. i'll try anything at this point.
@nxt: DicePlayer is unable to play high profile 720p mkvs on the transformer without lag. This is true in all versions of honeycomb and in ICS. and ICS makes it even worse. Only players that are even somewhat watchable are MX and BS, and both still lag.

quick smart arse answer- stop whining, recode your goddam videos and accept the fact that the Tegra 2 chip is and always will be underpowered to play mkv's.
question: who the hell wants to play mkv's on a 10inch tab anyway, get a TV.

if you bothered to even read my original post, i asked how to recode them.
And i want to play mkvs on a 10 inch tab because i can't carry around a tv to school or on an airplane, and my tab has an HDMI out that i can plug it into a TV to play said videos.

also make sure you have the tegra 2 plugin for dice player, works fine for avi and mkv on ICS.

I use xenonmkv to transcode. It leaves the video alone but repacks the video and audio in a mp4 format. More tegra2 friendly.

720p mkv should play natively on ics as of now.I got them playing though I encountered an issue with audio not working with the stock app.

@bob dylan: i have the tegra2 plugin installed. dice lags so bad everything is unwatchable.
@pongo: sounds like an idea. any changes in file size? my mkvs are around 7gb, i don't want them to get any bigger.
@DarkLG: not sure how your able to play them, myself and many others are unable to get them to work properly on any player.

that defeats the purpose of this thread.... even a Galaxy S1 can decode high profile 720p MKV with dice player and stock, there should absolutely be NO reason why a asus transformer on a duo-core can't process 720p mkvs when a single core can.
encoding a video takes too much time and it shouldn't be necessary.

actually zephik, my original post was asking how to reencode them to get them to work. so he was right in what he said.
I do agree with you though, there is no reason why the transformer can't do it other than issues in honeycomb and ICS. my galaxy nexus can play even do 1080p videos without any issues, but i'd much rather watch things on a 10" screen instead of a 4.6"

Why the hell you keep comparing Tegra 2 with Nexus's TI OMAP cpu assisted with PowerVR GPU? Despite same Cortex-A9 "base" architecture those are totally different CPU/GPU systems. All you see is that marketing bull**** with "CORES! Ghz!"?!
Tegra 2 is missing SIMD-instructions block needed to succesfully decode high profile/high bitrate h264 video in hardware accelerated mode. And you have nothing to do with it. Point.
And talking about high bitrate - 7GB sized videos looks like 9-10Mbps video stream for regular 1h40m movies. Thats way too high for Tegra2. Its upper limit is somewhere near 5Mbps. And preferable Main Profile encoded.
But if you want - you can continue complaining and comparing your TF with nexus or whatever you want. Thats pointless.
So the bottom line is - reencode.
You can find Handbrake profile on this forum, for example. Or try to find best acceptable settings yourself.

i think the reason why people, myself included, assumed that is because the tegra2 was being shown off as being capable of playing HD video, which, it is, but just not all hd video, and not the most common form of it, in the high profile.
i do thank you for giving a technical reason though. i had always been under the impression that the tegra is simply the most powerful out there, when i got my Gnex, that was proven very wrong.
i've been looking into the reencoding, as well as reripping. and thanks to a few good posters i have some good setups. Now just to setup my laptop and hopefully that will be powerful enough so it doesn't take 20 hours to do one movie.

One S video output resolution

Anyone who's got the phone yet tested if the One S outputs 720p through HDMI?
It's basically the only thing I can't find, I did however find that the One X does, but it has got a 720p screen itself.
Michael

Hello,
I have connected the one S to my sony HD TV.
the result is a bit disappointing for two reasons:
quality is not so good
latency for example when slide photos is high
I'm using a MHL cable from PNY:
PNY Adaptateur MHL (Mobile High-Definition Link) vers HDMI®
supposed to be compatible up to 1080p.
I didn't check yet the format resulting from TV point of view. I will try to find that and tell you.
For photos on TV, the Sony and HTC integrated DLNA is far better but not working all the time(seems that the TV is not visible as DLNA client all the time)

Bonus question: Is there a difference from using an MHL-adapter og the wireless dlna thingy?

Probably more lag with the wireless. Its not the best i've used it on 1080p and 720p, I think its outputting the native resolution of the phone.

Anyone got some new inputs? Thank you

I am looking forward to getting a bluetooth keyboard&mouse combo and an MHL cable.
I am surprised that it doesn't do 1080p, I thought that was native to ICS and that the GPU/CPU is the same as the One X

Yeah I thought it could do that too, and the reports of lag when outputting is kinda strange. It should be fast enough at half of full hd..

I have tested again MHL after upgrading to 2.21. Now scrolling in the gallery is smooth and videos are read in full 1080p(recognized by the tv).
I even have tested games, it's awesome!

I use a Logitech c920, FOV is great, It doesnt have IR night vision, (that wouldnt work properly with the headlights on anyway I guess), however it seems to work fine in the dark. When I get a chance I will upload a video.
Also, the built in DVR app is dog ****, i use an app from the play store called AutoBoy. It records the camera but also tracks your location which is handy, the other killer feature for me is that it allows you to flip the camera feed 180 degrees, which allows me to mount the camera upside down on the windscreen.

If you do get a chance that would be great I would like to see fov and image quality.

If its the ROCKCHIP/ARM CPU, then don't waste your time with a dashcam. Those things don't have video encoders, and you can't just capture raw. Means that you'll be software-encoding the video with the super-weak CPU. The performance hit is debilitating. I've been periodically tinkering with the idea of skipping the android layer and using ffmpeg to capture the stream directly, but hard to find the time needed to work on it.
If you get the INTEL unit, it DOES have a video encoder, AND has a much stronger CPU, it can do dashcamming much easier.

So a Logitech c920 (that does x.264 in hardware) won't work well?
Only asking because I was just getting ready to buy one for that very purpose...

The hardware encoder will not help you on the rockchip head unit if you go through Android to capture video. It will perform simultaneous decode and encode on the CPU before storing the video file.
Also FYI: It definitely does NOT do x264 in hardware. It will do H.264.
x264 is an open source SOFTWARE H.264 encoder.

Thanks for clearing this up for me. I really appreciate it! Sounds like that's out. I thought so anyway. It seems that we need to keep as much of a load off these head units as possible to conserve resources... That's ok, I had a plan 'B' anyway lol.

To be honest I've not found the performance hit to be that much at all. I have it running in the background all the time and apart from the splash screen when Autoboy loads I hardly know its there. I've not had any major laggyness with my MTCD for a while now, since Malaysk v6 probably and v7 (based on the last joying rom) is even better.

Hi, I've tried a HD camera but the problem it has the time stamp as well as GPS coordinates and I can't change them, I think the problem is the camera needs to comunicate with the car unit. Other problem was the image quality, I'm not 100% satisfied...so I've bought a Ambarela mini 0805(for 47€). Need to test it, it's on the way ...expect to get it this week. I'll post the results with sample video and images.
