H.264

[cata12ca]

I want to start this topic about the new released H.264 video codec technology. Please share your opinions here and also any information usefull regarding what this standard means.

I found some information here :http://en.wikipedia.org/wiki/H.264 and found out that H.264 brings 15-20% improvement in terms of video quality.
The new thing which comes with is:

• Better image quality at the same compressed bitrate, or
• A lower compressed bitrate for the same image quality.

Blinkotv com also implemented this standard and shared their feedback with the audience.

I want to learn more about this so feel free to write down your opinions.

Thank you.

Besides, some video formats which encoded with H.264 codec can be supported by adobe flash player to play, such as the video format of MP4, MOV, 3GP, 3G2.

So if you want to upload these video format file to your website to play with flash player, you should need to make sure that these video are encoded with H.264 codec.

Hi All,

I am using H.264 Encoder, and I am porting my code on DM-642 EVM Board (TI- board).

In my Encoder, one of the main function call is "EncodeOnePicture()". i am encoding one still video clip (CIF 352x288). I need to calculate the fps for this video clip.

My core is operating @ 600MHz.


How to calculate the fps? Please provide the suitable solution.
and give the formula for this. for calculating fps what are the parameters i need to consider(ex;Time taken for encoding the total picture..etc).

For incrasing the fps, Shall I optimize the my code or how to incrase the fps???

Please do needful.

Thanks & regards,

Srimanya
