H.264 BP aspect ratio

Hi Adriy,

You can specify the image width and image height as separate values in static and dynamic parameters of the codec.

Hi Vivek,

It is common in TV broadcasting that ratio of the video changes.

It can be 4:3 at the beginning (a TV program), then changed to 16:9 (while a movie), then back to 4:3. Aspect ratio value is stored in VUI part of the SPS in elementary H.264 stream. The resolution of the stream does not change.

So I need ability to specify ratio in H.264 encoder.

Andriy,

Vivek says that it is possible to provide aspect ratio  to be sent into codec inside SPS and PP though static and dynamic parameters.

Hello Yashwant,

I do not see how to set ratio in codecs for C66x platform (H264 BP Encoder, Version 01.24.00.01):

http://software-dl.ti.com/dsps/dsps_public_sw/codecs/C6678_Video_Codecs/01_00_001/index_FDS.html

There is no such option not in static nor in dynamic parameters. If you know a way to do it please let me know.

But there is an option to set aspect ratio in dynamic parameters in H.264 codecs from TI for other platforms.

Vivek,

Thanks for responce. I am waiting for release of new codecs.

Hi vivek,

Is there any update on the availability of this HP codec? This really makes time to market a lot easier, since most of the broadcasting features are needing this feature.

I wonder if the new HP codec also has de interlacing support.
