Upipe h264 & h265 attributes for uref

This macro is declared in upipe-framers/uref_h26x.h source file, line 31.

This function is declared in upipe-framers/uref_h26x.h source file, line 42.

This function compares the nal offset 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.h source file, line 42.

This function copies the nal offset 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.h source file, line 42.

This function deletes the nal offset 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.h source file, line 124.

This function deletes all NAL offsets.

Parameter list:

• uref: uref description structure
• ubuf: ubuf to prepend

The return value is an error code

This function is declared in upipe-framers/uref_h26x.h source file, line 42.

This function returns the nal offset 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

This function is declared in upipe-framers/uref_h26x.h source file, line 60.

This function iterates over the NALs of an uref. Initialize counter_p at 0, and don't modify the arguments between calls to this function.

Parameter list:

• uref: uref description structure
• counter_p: index of the NAL in the uref, initialize iteration at 0, will be incremented on every call
• offset_p: filled in with the offset in octets of the NAL in the uref
• size_p: filled in with the size in octets of the NAL in the uref, possibly including the next start code
• correction: correction to apply to the offsets is the uref has been modfied in the meantime

The return value is an error code

This function is declared in upipe-framers/uref_h26x.h source file, line 42.

This function compares the nal offset 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.h source file, line 96.

This function prepends a NAL to the given uref.

Parameter list:

• uref: uref description structure
• ubuf: ubuf to prepend

The return value is an error code

This function is declared in upipe-framers/uref_h26x.h source file, line 42.

This function sets the nal offset attribute of a uref.

Parameter list:

• uref: pointer to the uref
• v: value to set

The return value is an error code
