I'm trying to capture a video demo of my iPhone app so I can post it on Youtube.
I'm using Jing application (http://www.techsmith.com/jing/) for Mac, and was able to capture a video of the app. However, I looked at the resulting file size and it's 130MB!!! That's huge!
The video is 3:40 mins.
Any tips on how I can make the size of the file smaller, so that I can easily share it and post it on Youtube?
Thanks!!
Make the dimensions smaller, don't have a keyframe as every single frame, change the quality from best to good, same for audio (best to good), change the format. Isn't it kind of strange that you're posting a SWF movie for an iPhone app? Haha, anyway, hope this works!

I need help. I can’t figure out how to write a mini application on Flutter where video files and pictures are broadcasted on the monitor screen. It should look like a photo frame with video files. Do you have any ideas how to implement this?
It is not possible to combine the video file and pictures in the application. This is an application for constantly displaying advertising content on the monitor. Do you have any other ideas about this?
During image upload on iOS we experience a memory spike at the end of the upload and we get memory warnings during upload of a picture taken by the camera (experienced on iPhone 5 and simulator). Additionaly, the upload takes pretty long. For our app we don't really need the full quality photo of the user.
Is there a way to resize the image before upload (like there is a setting for upload quality of a video)?
Client side resizing is not currently supported. I'll add it to our tracker.
(It's worth noting that if you ask for an image/jpeg instead of an image/png, the size of the photo is significantly smaller)
I have searched everywhere and tried mixing and matching different bits of code but I haven't found anything that works or anyone with the same question.
Basically I want to be able to create video demos of iPhone apps that include standard UIKit elements and also the image coming from the camera (video preview layer). I don't want to use airPlay or iOS simulator to project onto the desktop then capture because I want to be able to make videos outside in public. I have successfully been able to video capture the screen with this code but with the video preview layer being blank. I read that its because its using openGL and what I'm capturing is from the CPU, not the GPU. I have successfully used GPUImage from Brad Larson to capture the video preview layer but it doesn't capture the rest of the UIView. I have seen code that combines both and converts to an image but I'm not sure if that would be too slow for realtime video capture. Can someone point me in the right direction?
It might not be the cleanest solution, but it will work nonetheless: did you consider jailbreaking? I hope Apple does sue me for this one but if you really want to record your screen then simply install a screen recorder. Enough options can be found: http://www.google.be/search?q=iphone+jailbreak+record+screen
And if you don't like it: recover your phone for a previous backup.
(for the record: I'm against jailbreaking and posting this from a productivity point of view)
I have created a PDF viewer on iphone. Currently my app is able to detect links to web pages and buttons for navigation within PDF.
But it unable to play Audio/Video contents embedded with PDF.
I creates custom PDf which has button(link to a local video file) to play video file. But iphone can't play the video. (when I tap on button, it says "NULL file ....")
I want to know is it possible to do? and if anyone have done it please give me a help. It will be a huge help for me.
No it is not possible to play a video inside a PDF,
if you cannot play the video on an iPhone, i would suggest to convert it to a file that the iPhone can play
You can do this by using PSPDFKit.
See documentation. Its best. :)
I was able to play the pdf embedef video not by acobat official app but thru thr drop box app! Wonder why acrobat not providing the function.

This is the dropbox pdf file with embeded MP4.
I was wondering what is the best way to display a big PDF file (it's a map actually) using iPhone SDK (the file is around 5MB), because it's really slow in a UIWebView.
I want to be able to scroll through the PDF and zoom in/out.
Also do you think that it would be better to convert it to a PNG?
Thank in advance
You can display the PDF using quartz it is faster, but it requires more code to handle it. You can download the quartz example from Apple. The only drawback I have seen is that zooming isn't as smooth.
