Parallel Video Processor

[javlak]

The Parallel Video Processor is a utility that allows you to create a cluster of PCs and use them to collaboratively encode videos with x264 and/or x265.

I created it because I thought x265 encoding was slow at that time and it was written exclusively for x265, but after a few weeks I thought that x264 support would be a good addition.

I have tried to test as much as I could but I'm only one person so I'm pretty sure the app is riddled with bugs at the moment.

I have a blog about it, it's located at: http://parallel-video-processor.blogspot.com. There's also a quickstart guide there.

Grab it and let me know what you think.

A few gotchas out the top of my head:

a) If your video file is an avisynth script, make sure that each node gets a different copy of it. That is because when an avisynth script is detected, PvP will try to edit it so that the node processes the amount of data that it's supposed to (usually it tries to do so through FFMPEG's -ss and -t or through x26x --seek and --frames). So if for example you are using an avisynth script over a network share, you should just create as many copies of the scripts as the number of nodes and have a unique script per node.

b) If you are using benchmarking to sort out how much processing each node should perform, ALWAYS convert it to weights. Benchmarking is somewhat volative. A system might receive a score of 13 one time and the next 12 or 14. That means that if your encoding has failed, there is a chance that the calculation of video processing will not be the same as the time before, resulting in a period of video missing or being duplicate.
