i am trying to encode H.264 1080p stream,i set the frameRate to 30fps,but the output is only 15fps so far.

Is there any way to make it 30fps for encoding?

Thank you

Hello,

If you are using the latest PSDK you must follow the steps from this guide:
software-dl.ti.com/.../Overview.html
Please start with "1.3.2.1. Prerequisites (One-time setup)" chapter, after this "1.3.2.2. Build Steps"
You could use this command MACHINE=am57xx-evm bitbake omapdrmtest instead of MACHINE=am57xx-evm bitbake arago-base-tisdk-image.

When needed, source code under the work directory (e.g., /tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/omapdrmtest/1.0.0-r22/git) can be modified.
After the modification is done, run the following commands to force recompilation with the new code and rebuilding of the recipe, e.g.,
MACHINE=am57xx-evm bitbake omapdrmtest --force -c compile

If you are not using the PSDK5.0 let me know so I could provide you the corresponding guide.

Hope this helps.

Hello,

The recommended way is to use yocto ( MACHINE=am57xx-evm bitbake omapdrmtest).
