I am implementing an online video editing platform, as a part of which, the users edit their videos online, and then export the edited video either in native format (suppose .xyz) or other standard video file formats like .mp4, .mov, .avi etc.
My question is: how should I go about implementing the video exporting part? I looked it up around the internet, and found some interesting topics that might be of use, like video web codecs and lossless compression of video files.
I am implementing the backend of the application in Spring, and I am a complete beginner in these areas.
Any help on how I should get started and implement this video file exporter would be greatly appreciated.

I've written a simple media player that uses java sound and a bunch of different SPIs to give support for various audio formats. I haven't been able to find an SPI for .m4a yet though. I've looked at JAAD but it seems to only have an SPI for AAC, not M4A.
Is there one out there?
So after doing more research, it look like JAAD should in theory work for .m4a and .mp4 containers if the audio inside is AAC. For me, It's going as far as getting the dataline, but then it's not actually reading bytes from the decoded stream. I posted this as a question here: Java sound not playing m4a files through JAAD
I am pretty new to image capturing using java. Just started working in java.
What i want to ask is i have two flv videos i will like to combine. I searched the internet and many people said about xuggler.
I have a looked on it and did not found any documentation or tutorial regarding this.
I do have it that i will have to capture frames continuously and than
add each frame with each other as i want a picture in picture video
and than form the video from those frames.
Please can anyone help me out here , how to capture continuous frames from an flv file and join them so a new video output can be obtained. Any hint or tutorial will be great. Thank you. I am using adobe flash builder and red5.
If you need to tutorials to get started on Xuggle I suggest that you take a look at Xuggle Wiki. This page should help you to understand basic use of video encoding/decoding.
Then you should be able to adapt the source code of examples. I think you could use this example to combine your 2 flv files. Of course, you will need to change it to combine 2 video files.
I'm looking for a small library to play, merge and change pitch for .wav files.
I've tried JASS, beads, something from anyexample.com, basic javax.sound examples, Sonia Sound Library etc.
Can anyone help me? I just need change pitch, merge and play wav files in Java.
Have you tried the Java Media Framework? Even though it has its limitations, it may be an option. In addition, the wikipedia article (linked above) has a listing of alternatives - maybe one of them does the trick for you.
I wanna split a video file into several fragments which can be played individually.
Is there any java library can be used in this situation?
Or if Xuggle can be used, can anyone give me an simple example.
Thanks
A video file? There's quite a few video codecs, file formats. For a general solution try ffmpeg it's not a Java library but runs on all platforms.
I am working on a software that receives an MJPEG stream from an IP camera and displays it on the screen. Now I'd like to record the stream at the same time in some movie format.
I'm still quite new to Java and got a little lost in the jungle of libraries etc. that are available. What I found was JMF but it looks terribly outdated and unmaintained.
Does anyone here have any suggestions for proper video encoding libraries (must at least support Linux, but OS independent would be perfect)?
Thanks.
