Hi,
I recently went through the DVB API and found following structures for
DMX_SET_FILTER
typedef struct dmx_filter
{
uint8_t filter[DMX_FILTER_SIZE];
uint8_t mask[DMX_FILTER_SIZE];
uint8_t mode[DMX_FILTER_SIZE];
} dmx_filter_t;
struct dmx_sct_filter_params
{
uint16_t pid;
dmx_filter_t filter;
uint32_t timeout;
uint32_t flags;
#define DMX_CHECK_CRC 1
#define DMX_ONESHOT 2
#define DMX_IMMEDIATE_START 4
#define DMX_KERNEL_CLIENT 0x8000
};
does anyone know the meaning of following fields?
uint8_t filter[DMX_FILTER_SIZE]; // this is the table id
uint8_t mask[DMX_FILTER_SIZE]; // ??? it sometimes is set to
0xff, but for PAT it is also 0x00
uint8_t mode[DMX_FILTER_SIZE]; // ???
I haven't found any reference for this in the DVB API Specs
regards,
Markus
