I am making an video application. In the list of the media, I would like to show the video frame as thumbnail to indicate my video.
There is standard method to extract the first frame from the video. However, I would like to let the user to use any frame as the thumbnail. Is there any method such that I can extract a frame by specific time input by user?

I would prefer to not have to purchase a Flip Video Recorder to provide me the frame by frame playback needed (coaching girls softball) for instant instruction at practice. Is there an app that provides playback of video at a frame by frame rate?

Getting frames from Video Image in Android
I wanted to know if it is possible to extract frames from a running Video in Android? I need to extract frames at regular intervals and send them for further processing.
Would someone be able to find an answer for me?
i'm doing some experiments with OpenGL using the GLSurfaceView introduced in 1.5 In my Renderer I keep track of the time spent to render the last frame and pass this value to the method that update my model. The goal is to keep objects movements on the screen independent from the rendering time. Now this seems to work perfectly in the emulator, but on the real device is at least 4/5 times slower! Has anyone experienced the same problem? Or, anyone has a clue of what I'm doing wrong? Here's pieces of the code I'm using

So I have created a client to interact with RTSP server, I have succeeded in doing this.I am able to get the video/audio frame from RTSP server (MySpace) in Android. Now I want to play the frames. I have searched OpenCore APIs to play the frames, but didn't get any APIs. My investigation: There is a class PlayerDriver.c It creates two sinks one audio and other video. handleSetVideoSurface handleSetAudioSink Two objects of type PVPlayerDataSinkPVMFNode are created. I suspect this class has a way to give the stream as input, but I am not getting the definition of this class. Can you suggest me is there any class I need to look into it?

View 2 Replies View RelatedJust curious, is there a way (or an app?) that will help me auto delete texts after a certain time frame has passed? I ask this because I have 2 threads that take EXTREMELY long to load due to the large number of texts within each (one has 1,300 texts, the other has 940). It is starting to get annoying having to wait 7-10 seconds for the thread to load. I have actually tried manually scrolling up and deleting the oldest texts but that was just WAYYY too much work and it took probably a good minute just to get to the top.
View 10 Replies View RelatedI wanted to write an application that makes use of the camera taking extremely slow frame-rate video and uploading it. Right now I am reading over this:
http://itp.nyu.edu/~sve204/mobilemedia_spring10/androidCamera101.pdf
My question was in regards to the camera's use. The above article makes use of a canvas to preview the image, if one didn't want to preview the image before taking it could that be done? Is it necessary to use a preview of the camera image or can I just call takepicture to take the picture and catch the resulting callback to save it to a file?
On a Nexus One (for example), the camera application is able to capture H.264 video at 720x480 (the "High" quality setting). However, when using the MediaRecorder API, it always seems to capture at a fixed frame size of 320x240.
I would expect the setVideoSize() method to control the frame size (as in the prepare fragment below), but it appears to have no effect (using Froyo 2.2 Android SDK).code...
Discussions on the android developers list seem to indicate this is a long standing issue. Can anyone advise how the frame size can be controlled, or if it is possible at all with the current API?
I've created an application that show around 250 images in ImageView. Images are loaded one after another, 15-30 images per second. Basically the whole thing gives an illusion of a rotating 3D object, at least it should.
The problem is next, app hangs when loading certain images(i.e. I see a few seconds of fluid animation and then animation hangs, jump 10-15 frames(images) ahead and continues. It always happens at the same places in animation cycle.
I though that Android might not have enough resources to handle something like this, so I've resized images to half their size, but it did't help. I've tried buffering images but that did't help either(actually, maybe a little, I think that animation looks a little bit smoother).
And now the weirdest thing. I use the touch screen to allow users to "rotate" the 3D object on those images, and while rotating I again experience those hangs at exactly the same places as with the animation.
All images are in .png format and their size vary from 15kB to 40kB.
I use the following code for the animation:

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?
View 2 Replies View RelatedI am using a VideoView to display a video. I am using setOnPreparedListener and setOnCompletionListener to do stuff before and after the video starts and ends.
I was wondering how I could go about detecting some point of time in the video. For eg, say I want to write log to a file when the video has played for 10s. How can I detect the 10s mark?
I am creating a program which requires me to change a setting in the program when the video reaches specific points (at 1/3 of the video's completion, 2/3's and on completion). Android has a built in callback method for completion so performing an action at that point in time is not difficult. However, I don't know how to go about checking when the video has reached 1/3 and 2/3's of completion.
View 1 Replies View RelatedI want to do video recording and uploading functionality in android application.Video recording and uploading need to be done on same time.
When user click on Record button , video recording need to be started and once user stops the recording , then recorded video need to be uploaded on remote server.
As mentioned audio stops after some random number of times when played from either Music/Video player. After some debugging, I found that the problem is:
In "android_audio_output.cpp"->audout_thread_func() there is a call to wait(iAudioThreadSem->Wait()) just before the while(1) and it is waiting indefinitely for something.
Can anybody tell me what is it waiting for and why is it not able to come out? From what I can understand, it is waiting for a signal (semaphore) but where is it expecting a signal from?
I get a video recording time limit on my LG G2X. It stops at 10 minutes no matter what video app I use. I have 30 gigs of SD space so that is not the issue.

So, I'm having a small issue trying to share videos on Youtube. Essentially, I'm forced to log in every single time I want to upload a video. Here's how it happens: I take a video with the stock camera app. Go to the gallery, and click share. Choose Youtube. It asks me to login. I do, and it uploads fine over wifi. Take another video, same steps, and I'm asked to login again. The problem is, I have a long username, so this is really annoying. I'd think it would cache my username for at least as long as the youtube app is still open in the background, or gallery, or something. I've tried going into the youtube app directly, logging in, and then doing all this. No matter what I do, I have to login to youtube every single time. There are other Droid threads about login errors to youtube via the app, but I'm not experiencing that - I'm able to login fine, I'm just annoyed I have to do it every single time I want to use youtube, be it via the app or sharing through gallery. I'm learning to Cut All when I login the first time, then pasting each subsequent time, so at least I'm only retyping my password each time. Which makes it not a huge deal, but still an annoyance Especially since I tend to upload in batches. Anyone else experiencing this? Is this a security thing or did they just forget the "remember me" checkbox?

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?
