VP8 Hardware Encoder

[jp.en...@gmail.com]

Hi,

I know there is a list of available processor to encode VP8

http://wiki.webmproject.org/hardware/socs

But what hardware card is use by video cloud company ?

What real life graphic card should I bought to encode VP8 on my personal computer ?

Thanks !

The vast majority of video companies use the libvpx software encoder to
encode VP8. This is true for other video formats as well, such as VP9
and H.264.

In general, hardware encoders give worse quality at a given bitrate than
software encoders. For many applications, it's a better investment to
spend money on a better CPU than a dedicated HW encoder. There are
certainly applications where a HW encoder might make sense, but you
should probably evaluate CPU encoding first.

This is very useful. I was wondering why these IP camera's video compression ratio is so low. 

According to this, they might be using hardware encoders.

Thomas, do you know what has caused this (inefficient hardware encoder)?
