[in] | buf | Pointer to buffer containing the first 54 bits of the frame. |
[in] | size | Size of buffer containing the first 54 bits of the frame. |
[out] | phdr | Pointer to pointer to struct AACADTSHeaderInfo for which memory is allocated and header info is written into it. After using the header information, the allocated memory must be freed by using av_free. |
