Converting an SVG animation to a video with the MediaRecorder API and a hidden canvas.

Drawing frames from img elements can introduce an extra delay, so this version generates all the frames upfront and then renders them in a loop with requestAnimationFrame().

Lately I need to use CiteSeerX dataset in my research, and I've been following the instructions [on this blog][1].

Sadly, due to the update of OAIHarvester, that is not working anymore. Here is my version that works.

1. Download [OAIHarvester2][2] from oclc.org, the latest version is 2-0.1.12 when I write this.

2. Run such command to download full CiteSeerX dataset:

   java -classpath .:harvester2.jar:log4j-1.2.12.jar:xalan.jar:xercesImpl.jar:xml-apis.jar ORG.oclc.oai.harvester2.app.RawWrite -out citeseerx_alldata.xml  http://citeseerx.ist.psu.edu/oai2
