Android :: Real Time Capturing Of A Video-android

Sep 24, 2010

I am doing a sample application for transfering realtime video from one android device to an emulator, in device side i can open video cam and a set an output file for it, while the recording is progressing, at the same time i am open a file stream and reading all the content by bytes with respect to avilablity, and writing a socket which is communication with the emulator. At the emulator side i am writing this to another file. When i click the recording stop button, i read the rest of the file from the device side and writing to socket stream. When i check the file size at the both side it is same But i cannot play the file at the emulator is side when i check with vlc, in the device side i can play recorded 3gp file So my doubt, same file i cannot access at the same time when one thread(android camera) is writing to the file or it will correupt?

Android :: Real Time Video Screen Capture?

Jul 1, 2010

I need to make a video as a DEMO for one application I have developed. I know that there are some experimental applications that use DDMS and achieve a framerate of 5-6 fps. This framerate is completely insufficient for my purposes since the application has smooth animations that i would like to show. Is there anyone that has found a way to do a real time screen capture on android? Should I settle for a capture of the emulator or a real video done with a real camera?

Android :: Real Time Phone Simulator On PC

Jul 28, 2010

After a round of hassle (many thanks to sontaikle), finally i managed to do some screen capture from my Android but right now I am thinking about this. Is there any way I can do a REAL TIME phone simulation on my PC. Its alike TV output from phone to projector (Galaxy S can do that) but I have other Android which have no TV output function from the phone, so I wonder if I connect the phone to PC and get the real time screen output (few second lagging is ok for me as well) to PC than I can project it out via projector during discussion, presentation. I have tried this Emulator, too bad its doesn't project that on the phone on PC. How to install Android SDK and play with Android 2.0 in the emulator - Android and Me

Android :: Modifying Audio In Real Time

Mar 23, 2010

I need to load an audio resource and play it, but I also need to be able to modify some parameters (like the volume, or the playback rate) while the audio is being played. For example, I might want to play a 10 seconds audio stream, and change the volume only after 3 seconds. Is there a way to do it? I've been experimenting a little with AudioTrack without results.

I'm trying to figure out how to write an app that can decode audio morse code on the fly. I found this document which explains how to record audio from the microphone in Android. What I'd like to know is whether it's possible to access the raw input from the microphone or whether it has to be written/read to a file.

Android :: Broadcasting Real Time Voice Using RTP

Feb 15, 2010

I am currently trying to braodcast real time voice from Android using RTP to other Android phones connected over Wifi Ad-hoc network. I have few questions in this regard,

1. How to control and set the RTP on Android? 2. Which Codec are supported by Android for voice communication? and how to incorporate them?

We are able to record a voice from microphone and store it on SD card for a playback. The next step would be to link the outstream of real time voice with RTP also incorporating Codec

General :: Android UI Rendering In Real-time?

Jun 10, 2013

I was wondering why Android keeps lagging a bit. I mean, quadcore should be fast enough to stop that from happening right? So I started Googling.

I got this article: [URL] .....

Basically it says this: Android's UI rendering thread does not work in real-time (the priority is not set at that), unlike iOS'. It's just about the one thing that's still better about iOS in my opinion.

How to make this thread render in real-time?

Android :: Video Producer - Capturing Full Motion Screen Casts On Android Device

Sep 18, 2010

I'm not a software developer, but I have done enough reading online to get the Android SDK, Eclipse, and the necessary downloads to get it all working.

I am able to capture device screenshots using the DDMS, but I need to capture full motion video of the system OS and apps for an Android TV commercial.

So far I've called the manufacturer and several software guys, but haven't had any luck. I've even tried the HDMI out, but it's not pixel accurate, which is very important.

There has to be a way to do this, since the apps are featured in other commercials and videos, and I don't believe that the only way to do it is to film the device's screen.

No matter how complex the answer and solution to this might be, I'd love to find out. Even if it means bringing on someone to execute it.

It needs to be at least a 20-30 fps capture.

Android :: Adjusting Application Permissions Real Time

Feb 25, 2010

I know you can apply Permissions for Applications on it's manifest.xml file. What I want to know is, can those Permissions be adjusted by the Applications on the fly?Here's my reason: say I have an application that is allowed to do "x", "y", and "z" (SMS, sockets, etc) Permissions. Now lets say I have a logical "user" that connects to this Application, and I want that user to only be able to do "x" and "y", but not "z" Permissions. It would be nice to have the Android Framework handle that instead of having a bunch of "if's" in the App code.

Android :: General Lag Error With Real Time Games

Mar 13, 2010

I developed and published a game about two months ago. Since then, I've received several negative comments about input lag in the game. Before releasing the game, I already took several measures to hopefully prevent lag from occurring: 1) Game is almost entirely written in native code 2) After initialization, my process never invokes the GC during gameplay (no GC executions from my process show up in the log) 3) Average FPS is generally > 30 fps 4) I tested the game on both a Motorola Milestone and an HTC Magic and I don't experience any noticeable input lag (except perhaps when the GC is executed by other processes) My guess is that the lag that users are experiencing is a result of the GC being invoked by another process. Has anyone been able to address this issue? Specifically, have any game developers been able to achieve a completely lag-free game and thus avoid negative ratings that drag down your app? The only other suspicious thing I've noticed is the following lines showing up in my log any time a SoundPool clip is played: D/AudioHard wareMot ( 1054): AudioMgr:AudioStreamOutMot::standby called D/AudioHardwareMot( 1054): AudioMgr:Output 0xb538 entering standby D/AudioHardwareMot( 1054): AudioMgr:Closing stereo device D/AudioHardwareMot( 1054): AudioMgr:Output 0xb538 exiting standby

i need to know about the LocationListener() working in the real time.

Sprint HTC Hero :: Best Video Capturing Settings?

Dec 19, 2009

This is the first phone I've owned with video capture available (LG Rumor, Instinct, Pre) and I notice there are a variety of settings available when it comes to video. One video I had recorded earlier today seemed more choppy with the exact same settings than another I took yesterday, the only difference I could really note was there was much more light in today's video. So is there a secret to beautiful video every time?

Android :: Change Playback Rate Of Track In Real Time

May 1, 2010

I would like to know if somebody knows a library to changing the playback rate of a track in real time. My idea is to load a track and change its playback rate to half or double. Firstly, I tried with MusicPlayer but is was not possible at all and then I tried with SoundPool. The problem is that with SoundPool I cant change the rate once the track is loaded. Here is the code I am using (proof of concept): Code...

Android :: Displaying Real Time Information During The Execution Of An Activity

Apr 6, 2009

I want to display the status of the activity execution on the screen using the TextView while activity is executing. I am appending the String messages at different stages of execution in the TextView, which is defined in the Layout main.xml (e.g. TextView.append("Server started..").

For e.g. I am running socket communication application in which my android application is the server and it is receiving the messages from the local desktop. So in this application I want to show "Server started.." message when socket server on android started , then a messge "waiting for message.." and then "message receivied.." when message received by android server.All 3 steps are the part of a single activity.

But in my case, I am getting all 3 messages at a time after activity execution completed. Is there any API available, using which I can show the status during the execution also.

Android :: Low Level Audio - Latency In SoundPool - AudioTrack For Real Time

Oct 26, 2009

I first have to say that I'm biased, 'cus I like to write music apps (like music generation apps). However, this affects games as well. It's somewhat disappointing how OpenGL has made it into the NDK now but there isn't any NDK methods to get to sound to have faster access. Over the weekend I did some more testing and if you make a "drum" app, for example, and play the sound using either SoundPool or AudioTrack, you will get about a 100ms delay buffer, which is clearly audible (gap).

I made a test app where when you touch the screen, upon the DOWN event, it would play a short sound (like a drum sound). It clearly was not real time responsive or even close - you could hear the delay. I'd be interested to know if anyone who has made a game has any trouble with sounds? It seems like they aren't going to really trigger real time enough if you use SoundPool, for example. Am I completely wrong? Seems like your game is going to perform an action, play a sound, but the sound will have latency which I would think would throw off the game a bit..................

Can Google MAPS do this? If not, is there an app in the market that can do this? I am hitting the road tomorrow for a road trip and that would come in handy!

Android :: Does Android Support Near Real Time Push Notification

Aug 7, 2009

I recently learned about the ability of iPhone apps to receive nearly instantaneous notifications to apps. This is provided in the form of push notifications, a bespoke protocol which keeps an always on data connection to the iPhone and messages binary packets to the app, which pops up alerts incredibly quickly, between 0.5 - 5 seconds from server app send to phone app response time. This is sent as data - rather than SMS - in very very small packets charged as part of the data plan not as incoming messages. I would like to know if using Android there is either a similar facility, or whether it's possible to implement something close to this using Android APIs. To clarify I define similar as: Not an SMS message, but some data driven solution As real time as is possible Is scalable - ie: as the server part of a mobile app, I could notify thousands of app instances in seconds I appreciate the app could be pull based, HTTP request/response style, but ideally I don't want to to be polling that heavily just to check for notification .. besides which it's like drip draining the data plan.
