H.264 BP encoder 720P @ 50Hz support

Nir Aloni

In the encode demo of the DM6467 EVM, the file encode.c has the following comment:

/* Capture an extra frame since encoder doesn't support 50/60Hz */
        if (Capture_get(hCapture, &hCapBuf) < 0) {
            ERR("Failed to get capture buffer\n");
            cleanup(THREAD_FAILURE);
        }

This means that the supplied H.264 BP encoder does not support the HD resolution of 720P50. Is that correct?

It is my understanding that the encoders yield elementary streams independant of refresh rate; can you specify which version of the DVSDK software you are using so I can investigate this furher?

I use the DVSDK version 1.40 that comes with the DM6467 EVM.

EDIT: Any progress with this issue?

For closing this issue I had some correcpondence with TI and following is the summary:

For *encoding*, 25/30 fps is the standard frame rate being tested and specified (the device can go up to 1080 standard 25/30 fps which is full HD). Frame rates higher than 25/30 are not in the tested or supported scenario.

Dm6467 is not promoted for doing encoding at higher frame rates than the current HD standard / video format requires (25/30 fps).
