Hi All,
I have asked this question in the ffmpeg mailing list and received an
answer but yet, due to other considerations, i have to implement the
solution using mencoder.
I am setting up an encoding server for a video sharing website. I already
installed mencoder and i can encode some videos into FLV format.
My questions:
1. How do i add more codecs?
2. How do i insert a "watermark" into the encoded video? Can it be
transparent?
3. Can i add any hardware to reduce the loads on the machine?
Thank you for any guide and help,
Nahum
