h264_freertos

h264_freertos#

Overview#

This project read the h264 files from SD card, decode them and show the frames in LCD panel.

Prepare the H264 files#

Name the H264 files like 000.264, 001.264, 002.264, …, and save them to the root path of the SD card. Please starts from 000.264, if there is only one file, name it as 000.264. This project reads the files one by one and decode. The recommend file is: https://github.com/cisco/openh264/tree/v2.1.1/res/test_cif_P_CABAC_slice.264

Running the demo#

This demo could run without debug console. The debug console shows the frame size, decode frame rate, and some error information.

NOTE: For better performance, this project places the decode buffer to DTCM. So the decode buffer size is limited by the DTCM size. See the file h264_dec.cpp for more details. When the H264 file frame size is larger than decode buffer size, then the decode fails and error log is output in debug console. If frame size is more important than performance, please increase the decode buffer size (macro DEMO_DECODE_BUF_SIZE in h264_dec.cpp) and place decode buffer in other larger RAM region.
