Hi,
I'm using J6 EVM (REV H), which is running in QNX.
I'm trying to encode a YUV file to H.264 file.
Encoder library Initialization, Encode Instance Creation is success.
After starting the encoder, when i tried to read the frame using "enc_read_frame", i'm not able to read any frame.
I have attached my source code for your reference.

Kindly let me know, whether the input parameters what i'm setting is fine or not.
While debugging the source code of video encoder, it is getting failed while reading from "get_list_head" in enc_read_frame function (File : bsp-TI-DRA74x-OMAP5-SDP6.6\bsp-TI-DRA74x-OMAP5-SDP6.6\src\utils\videolib\videnc\dce_enc.c)
Kindly do the needful to resolve the issue.
