Application interface for the CAT decoder and the CAT generator. New decoded CAT tables are sent by callback to the application.
◆ dvbpsi_cat_attach()
bool dvbpsi_cat_attach |
( |
dvbpsi_t * | p_dvbpsi, |
|
|
uint8_t | i_table_id, |
|
|
uint16_t | i_extension, |
|
|
dvbpsi_cat_callback | pf_callback, |
|
|
void * | p_priv ) |
Creation and initialization of a CAT decoder. It will be attached to p_dvbpsi.
- Parameters
-
p_dvbpsi | is a pointer to dvbpsi_t which holds a pointer to the decoder |
i_table_id | Table ID, here 0x01 |
i_extension | Table ID extension. |
pf_callback | function to call back on new CAT |
p_priv | private data given in argument to the callback |
- Returns
- true on success, false on failure
◆ dvbpsi_cat_delete()
Clean and free a dvbpsi_cat_t structure.
- Parameters
-
p_cat | pointer to the CAT structure |
- Returns
- nothing.
◆ dvbpsi_cat_descriptor_add()
Add a descriptor in the CAT.
- Parameters
-
p_cat | pointer to the CAT structure |
i_tag | descriptor's tag |
i_length | descriptor's length |
p_data | descriptor's data |
- Returns
- a pointer to the added descriptor.
◆ dvbpsi_cat_detach()
void dvbpsi_cat_detach |
( |
dvbpsi_t * | p_dvbpsi, |
|
|
uint8_t | i_table_id, |
|
|
uint16_t | i_extension ) |
Destroy a CAT decoder.
- Parameters
-
p_dvbpsi | handle to dvbpsi with attached decoder |
i_table_id | Table ID, here 0x01 |
i_extension | Table ID extension. |
- Returns
- nothing.
The handle isn't valid any more.
◆ dvbpsi_cat_empty()
Clean a dvbpsi_cat_t structure.
- Parameters
-
p_cat | pointer to the CAT structure |
- Returns
- nothing.
◆ dvbpsi_cat_init()
void dvbpsi_cat_init |
( |
dvbpsi_cat_t * | p_cat, |
|
|
uint8_t | i_version, |
|
|
bool | b_current_next ) |
Initialize a user-allocated dvbpsi_cat_t structure.
- Parameters
-
p_cat | pointer to the CAT structure |
i_version | CAT version |
b_current_next | current next indicator |
- Returns
- nothing.
◆ dvbpsi_cat_new()
dvbpsi_cat_t * dvbpsi_cat_new |
( |
uint8_t | i_version, |
|
|
bool | b_current_next ) |
Allocate and initialize a new dvbpsi_cat_t structure.
- Parameters
-
i_version | CAT version |
b_current_next | current next indicator |
- Returns
- p_cat pointer to the CAT structure
◆ dvbpsi_cat_sections_generate()
CAT generator.
- Parameters
-
p_dvbpsi | handle to dvbpsi with attached decoder |
p_cat | CAT structure |
- Returns
- a pointer to the list of generated PSI sections.
Generate CAT sections based on the dvbpsi_cat_t structure.
