This function is declared in upipe-blackmagic/upipe_blackmagic_source.h source file, line 111.

This function allocates and initializes a bmd source pipe.

Parameters list:

• mgr: management structure for bmd source type
• uprobe: structure used to raise events for the super pipe
• uprobe_pic: structure used to raise events for the pic subpipe
• uprobe_sound: structure used to raise events for the sound subpipe
• uprobe_subpic: structure used to raise events for the subpic subpipe

The return value is pointer to allocated pipe, or NULL in case of failure

This enum is declared in upipe-blackmagic/upipe_blackmagic_source.h source file, line 38.

This enum extends upipe_command with specific commands for bmd sources.

This function is declared in upipe-blackmagic/upipe_blackmagic_source.h source file, line 64.

This function returns the pic subpipe. The refcount is not incremented so you have to use it if you want to keep the pointer.
