mp4

I want to be specific as to what I am asking. I am not asking to modified any MP4 files, just extract metadata such as Width and Height and bitrate and encoding and this is not in the MP3 tags. I have tested Xuggle which works, but I need to have a library that does not use JNI or any native code. I already looked into MP4Parser, and Apache Tika, and they both does not extract metadata, just tag info or alter the file. Is there such java lib? Churk I actually found what I was looking for using Mp4Parser here is a simple lines of code to get what I wanted using Mp4Parser FileChannel fc = new

So I'm trying to play a simple intro animation video file that I've dragged into my project in XCode and therefore should be able to play from my mainBundle, right? With this code: NSURL *urlString = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"introvideo" ofType:@"mp4"]]; MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:urlString]; [player play]; I get this error message: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[NSURL initFileURLWithPath:]: nil string parameter' Any help would be great!

I need to open a mp4 video from the assets folder and play it with VideoView. I tryed with these two options, but none of them works.... mVideoView.setVideoPath("file:///android_asset/videos.mp4"); mVideoView.requestFocus(); mVideoView.start(); and... String uriPath = "file:///android_asset/videos.mp4"; Uri uri = Uri.parse(uriPath); mVideoView.setVideoURI(uri); mVideoView.requestFocus(); mVideoView.start(); These options didn't works, but if I try to open the video from the SDCARD it works perfectly, then, the problem is when I'm trying to load the video from the assets folder.

We're having trouble serving mp4s that will play on an ipad using a default rails 3 app. The mp4 is served correctly when viewing the route in chrome and other browsers on a desktop. Here is our code: file_path = File.join(Rails.root, 'test.mp4') send_file(file_path, :disposition => "inline", :type => "video/mp4") We hit 0.0.0.0:3000/video/test.mp4 to view the video and are presented with cannot play icon on the ipad. We've tried modifying various headers "Content-Length", "Content-Range", etc but they don't seem to affect the end result. We've also tried using send_data to some extent i.e.

In my Android app, I want to compress mp4 video by changing its resolution, bitrate. I don't want to use FFmpeg (because I don't want to use NDK), so I decided to use MediaCodec API. Here are my logical steps: Extract video file with MediaExtractor, then decode data. Create new encoder with my new resolution, bitrate and encode data. Using MediaMuxer to create a new mp4 file. My problem is: I don't know how to setup the connection between output of decoder and input of encoder. I can decode the video to a Surface or encode a new video from a surface. But I don't understand how to connect them.
