Is there any tips, suggestions, or available plugins for Phonegap that might be available to Capture a video using Phonegap's capture feature, then programmatically compress or reduce the quality of the video such that it can be uploaded to a server?
The video file sizes can become rather large with videos longer than 5 minutes. I would strongly prefer not to have save the video to the iPhone.
Currently it is not possible. You might have a look at this plugin, but up to Cordova 3.5 it is not possible to compress a video, and you can set its duration only on iOS

Im using uiimagepicker for the user to pick a video from photo library.
After setting video quality to low in image picker settings, a 5 minute or even a 2 min recorded video is still too big for upload. Is there anyway to compress the video size further. My guess is that i need to reduce the bitrate.
I am of course using assets to manage the file
I want to hide some private content on screenshots. Since Apple provide us only userDidTakeScreenshotNotification, the only way to achieve this is to convert image to video with DRM. According to these thread:
If your application uses FairPlay Streaming (FPS) your video content
will automatically not be captured by the iOS 11 screen recording
feature or QuickTime Player on macOS. The portion of your application
that is playing the content will be blacked out.
I found commercial implementation of these idea in ScreenShieldKit, but it costs money.
The main question:
How it's possible to convert image or label to FairPlay Streaming (FPS) video in offline mode?
I have tried many times to upload App Preview video.
But each time I failed.
Please recommend me best tool to convert my video to availble and how to.
Thanks
You must use Safari to upload your video.
I use QuickTime Player to record the screen of my app.
In QuickTime Player you can record in portrait and landscape, but you cannot rotate your screen during the record.
Open QuickTime Player > File > New Movie Recording (then select your device for camera and microfone).

Apple App Preview Video Guidelines
As you can imagine, Apple wants to generate a similar Look & Feel for all videos. Therefore they released some guidelines, which you should mind when creating a preview video.
15-30 seconds length
Maximum file size of 500 mb
.mov, .m4v, .mp4 format
Only use screen capture
No (very less) copy – due to the reason that you can’t internationalize your video and only upload it once in one language
Don’t overlay animated hands, you can use touch hotspots if really necessary
For games: Show more gameplay scenes than cutscenes
You can use voice over – but mind the internationalization part – Apple recommends to only use a very limited and professional voice over if you have to
Your preview video should only contain content for which you have the full rights (don’t show you app streaming content from an iTunes Playlist or a YouTube video)
App Preview Video Format
Now the most important part – which format or size should your video have. As you have already read in my screenshot size article it can be quite frustrating creating a lot screenshots in different sizes.
Apple recommends you to use the following app preview resolutions (this is already a summary, that you have to create the least amount of different video versions):
iPhone 5+ iPhone 6 Plus: 1920 x 1080
iPhone 6: 1334 x 750
iPad: 1200 x 900
When capturing video with phonegap on iOS the file size for a even a 1min capture is ridiculously large. Well, far to large to upload over a 3G connection reliably. I read that there is a native AVCaptureSession object that will allow the bitrate to be altered in order to reduce the file size. Has anyone implemented this in the phonegap video capture or can give me any pointers?
Found the deatils I needed here:
How can I reduce the file size of a video created with UIImagePickerController?
The important line for Phonegap users is in CDVCapture.m:
pickerController.videoQuality = UIImagePickerControllerQualityTypeHigh;
There are several presets that can be used e.g.
UIImagePickerControllerQualityTypeLow
phonegap provide quality argument when to navigate camera set :
quality:50
this is recommended for ios. if u need to reduce mean reduce quality.It have integer value (0-100) use this .....
I have an iphone application that uploads videos to youtube. It uploads the video files without a problem. But there is an issue that the thumbnail preview image is of very low quality.
My question is this, is it possible using the youtube api to set a different preview image?
No. this is not possible with the Standard API.
See this answer for possible ways forward. Youtube API - Set the Thumbnail of video
