This function is declared in upipe-framers/uref_h26x_flow.h source file, line 57.
This function compares the H26x encapsulation type attribute in two urefs.
Parameter list:
- uref1: pointer to the first uref
- uref2: pointer to the second uref
The return value is 0 if both attributes are absent or identical
This function is declared in upipe-framers/uref_h26x_flow.h source file, line 57.
This function copies the H26x encapsulation type attribute from an uref to another.
Parameter list:
- uref: pointer to the uref
- uref_src: pointer to the source uref
The return value is an error code
This function is declared in upipe-framers/uref_h26x_flow.h source file, line 57.
This function deletes the H26x encapsulation type attribute of a uref.
Parameter list:
- uref: pointer to the uref
The return value is an error code
This function is declared in upipe-framers/uref_h26x_flow.h source file, line 57.
This function returns the H26x encapsulation type attribute of a uref.
Parameter list:
- uref: pointer to the uref
- p: pointer to the retrieved value (modified during execution)
The return value is an error code
enum uref_h26x_encaps uref_h26x_flow_infer_encaps(struct uref *flow_def)
This function is declared in upipe-framers/uref_h26x_flow.h source file, line 66.
This function infers the encapsulation type from a flow definition packet.
Parameter list:
- flow_def: flow definition packet
The return value is encapsulation type
This function is declared in upipe-framers/uref_h26x_flow.h source file, line 57.
This function compares the H26x encapsulation type attribute to given values.
Parameter list:
- uref: pointer to the uref
- min: minimum value
- max: maximum value
The return value is an error code
This function is declared in upipe-framers/uref_h26x_flow.h source file, line 57.
