AVI player virtual device
This describes a virtual capture device which takes its input from an AVI file.
Functions
-
void pjmedia_avi_dev_param_default(pjmedia_avi_dev_param *p)¶
Reset pjmedia_avi_dev_param with the default settings. This mostly will reset all values to NULL or zero.
- Parameters
p – The parameter to be initialized.
-
pj_status_t pjmedia_avi_dev_create_factory(pj_pool_factory *pf, unsigned max_dev, pjmedia_vid_dev_factory **p_ret)¶
Create a AVI device factory, and register it to the video device subsystem. At least one factory needs to be created before an AVI device can be allocated and used, and normally only one factory is needed per application.
- Parameters
pf – Pool factory to be used.
max_dev – Number of devices to be reserved.
p_ret – Pointer to return the factory instance, to be used when allocating a virtual device.
- Returns
PJ_SUCCESS on success or the appropriate error code.
-
pj_status_t pjmedia_avi_dev_alloc(pjmedia_vid_dev_factory *f, pjmedia_avi_dev_param *param, pjmedia_vid_dev_index *p_id)¶
Allocate one device ID to be used to play the specified AVI file in the parameter.
- Parameters
param – The parameter, with at least the AVI file path set.
p_id – Optional pointer to receive device ID to play the file.
- Returns
PJ_SUCCESS or the appropriate error code.
-
pj_status_t pjmedia_avi_dev_get_param(pjmedia_vid_dev_index id, pjmedia_avi_dev_param *param)¶
Retrieve the parameters set for the virtual device.
- Parameters
id – Device ID.
param – Structure to receive the settings.
- Returns
PJ_SUCCESS or the appropriate error code.
-
pj_status_t pjmedia_avi_dev_free(pjmedia_vid_dev_index id)¶
Free the resources associated with the virtual device.
- Parameters
id – The device ID.
- Returns
PJ_SUCCESS or the appropriate error code.
-
struct pjmedia_avi_dev_param¶
- #include <avi_dev.h>
Settings for the AVI player virtual device. This param corresponds to PJMEDIA_VID_DEV_CAP_AVI_PLAY capability of the video device/stream.
