Who knows what tool that was used to encode this media?

Recently I've found on the web some videos converted with a special tool.
The problem is i don't know what tool was used.
I've seen something like "Imported with GPAC 0.5.0-rev4065."
Here's what MediaInfo said: Attachment 17203

Now, i'm asking for tool that was used to encode this media with settings and commpresion like in this image.

Thanks in advance!

PS: Actually this was a FLV file with streams extracted using FLVExtract then imported using GPAC, re-encoded & muxed using YAMB Tool.

What tools is using this guy to re-code this video and how to use GPAC?
Some tuts may be useful.
