DM368 h264venc-r error

Hi Champs,

I have a problem to run the H.264 enc Sample Test Application on DM368 EVM with DVSDK. The compilation of executable file h264venc-r was succeeded, but at running this file on DM368 Linux, it failed with error.

- Use DVSDK_4.02 4_02_00_06
- Refer "h264_encoder_dm365_userguide.pdf" for compiling and running sample test app
- Use default parameters in testparams.cfg

- Note:
1) I replaced codec engine package from DVSDK original to downloaded "codec_engine_2_26_01_09" because "cetools" directory is included in original package in DVSDK, so error was output when make h264venc-r.
2) Use cmemk.ko, edmak.ko, irqk.ko in targetfs directory that installed when setup DVSDK, not modules in codec package. Because "cmemk: no symbol version for module_layout" error was output with codec package modules when running loadmodules_h264enc.sh.

When run "h264venc-r", the following error was output and stopped process.

Any idea what did cause this problem and how can I resolve?

Best regards,

    Hello,

    It looks like the encoder creation has failed. This is due to wrong parameter setting. Could you post the encoder parameters.

    Along the path \ti\sdo\codecs\h264enc\lib you can find debug library h264venc_ti_arm926_debug.a. Use this library to build the application and run. It will generate logs from which it is possible to identify which parameter was set incorrectly.
