Members detail

#define UPIPE_MPGVF_EXPECTED_FLOW_DEF

This macro is declared in upipe-framers/upipe_mpgv_framer.h source file, line 35.

We only accept the ISO 13818-2 elementary stream.

This macro is declared in upipe-framers/upipe_mpgv_framer.h source file, line 33.

#define _UPIPE_FRAMERS_UPIPE_MPGV_FRAMER_H_

This macro is declared in upipe-framers/upipe_mpgv_framer.h source file, line 26.

enum upipe_mpgvf_command

This enum is declared in upipe-framers/upipe_mpgv_framer.h source file, line 39.

This enum extends upipe_command with specific commands for mpgv framer.

Identifier	Value	Description
UPIPE_MPGVF_SENTINEL	0
UPIPE_MPGVF_GET_SEQUENCE_INSERTION	1	returns the current setting for sequence header insertion (int *)
UPIPE_MPGVF_SET_SEQUENCE_INSERTION	2	sets or unsets the sequence header insertion (int)

bool upipe_mpgvf_get_sequence_insertion(struct upipe upipe, bool val_p)

This function is declared in upipe-framers/upipe_mpgv_framer.h source file, line 62.

This function returns the current setting for sequence header insertion.

Parameters list:

upipe: description structure of the pipe
val_p: filled with the current setting

The return value is false in case of error

struct upipe_mgr * upipe_mpgvf_mgr_alloc(void )

This function is declared in upipe-framers/upipe_mpgv_framer.h source file, line 52.

This function returns the management structure for all mpgvf pipes.

The return value is pointer to manager

bool upipe_mpgvf_set_sequence_insertion(struct upipe *upipe, bool val)

This function is declared in upipe-framers/upipe_mpgv_framer.h source file, line 80.

This function sets or unsets the sequence header insertion. When true, a sequence headers is inserted in front of every I frame if it is missing, as per ISO-13818-2 specification.
