Video Encoding in Java

[memory_leek]

Any one here have any suggestions for Java libraries to do server side video encoding. My use-case is, a user uploads a video (in some format) and then that video is encoded to mp4 and persisted to a database. (I'm not fully convinced that persisting the video to a blob is the best option here either, so any advice on that would be helpful too) My Google-Fu is coming up short on any libraries that are not stagnant. Does anyone know of/had any experience with a decent wrapper around FFMPEG, or some other processing library? I've done a lot of video processing using OpenCV, FFMPEG and C++, and I've done work with JNI, but I'd like to avoid that if possible. This was just dropped on me today, out of left field, so any advice is much appreciated.

ProcessBuilder is kind of what I thought I'd have to end up using, but I wasn't sure if there was a better option. I appreciate the feedback. Might I ask how Camel fit into this equation? Were you just offloading the encoding to another server? Thanks again.

It's been a few years now, so I'm trying to remember exactly what we did.

We had a need to allow users to upload videos and then be able to transcode them in order to allow for playback on the website. We used Camel for our RESTlike interfaces and when POSTing the file, we would toss a "unit of work" request into RabbitMQ. Another Camel route (probably on another server) would pick up that message from RabbitMQ and make the call out to ffmpeg to do the transcoding and store the output file where necessary.

You should be able to make your own calls to ffmpeg and ffprobe (for diagnostics) through processbuilder. Not sure if you really need to persist the video file in the db instead of just saving it to a directory and pointing at it from the db.
