Upipe wrapper for sound ubuf and uref

This macro is declared in upipe/uref_sound.h source file, line 107.

This macro is declared in upipe/uref_sound.h source file, line 31.

This function is declared in upipe/uref_sound.h source file, line 57.

This function returns a new uref pointing to a new ubuf pointing to a sound. This is equivalent to the two operations sequentially, and is a shortcut.

Parameter list:

• uref_mgr: management structure for this uref type
• ubuf_mgr: management structure for this ubuf type
• size: size in samples

The return value is pointer to uref or NULL in case of failure

This function is declared in upipe/uref_sound.h source file, line 187.

This function allocates a new ubuf of size new_size, and copies part of the old sound ubuf to the new one, switches the ubufs and frees the old one.

Parameter list:

• uref: pointer to uref structure
• ubuf_mgr: management structure for the new ubuf
• skip: number of samples to skip at the beginning of each plane (if < 0, extend the sound upwards)
• new_size: final size of the buffer, in samples (if set to -1, keep same end)

The return value is an error code

This function is declared in upipe/uref_sound.h source file, line 203.

This function consumes samples off a sound uref, and adjusts dates and duration accordingly.

Parameter list:

• uref: uref structure
• consume: number of samples to consume from uref
• samplerate: sample rate

The return value is an error code
