◆ create_cfile()

lives_clip_t * create_cfile	(	int	new_file,

set default values for a clip (in memory)

if new_file == -1 we create (malloc) a new clip and switch to it

setting its handle to "handle" (reload / crash recovery)

if new_file != -1 the parameter "handle" is ignored, and we switch to new_file, without mallocing anything

"handle" in the clip must have been set already (called from get_new_handle() and get_temp_handle()) – get_new_handle() will set name and fliename and switch back to original clip.

default values are then set for the clip

a "unique_id" is assigned via uuidgen or lives_random()
type is set to CLIP_TYPE_DISK
img_type is set depending on prefs->image_type
frames is set to 0 etc.
loaded is set = to is_loaded

WARNING: on success, returns the clip, and changes the value of mainw->current_file !! returns NULL if: new_file is out of range or points to a NULL clip; new_file is -1 and all free clips are in use (unlikely), or malloc fails.

◆ get_temp_handle()

boolean get_temp_handle ( int index )

get a temp "handle" from disk.

Call this to get a temp handle for returning info from the backend (this is deprecated for simple data, use lives_popen() instead whenever possible)

This function is also called from get_new_handle() to create a permanent handle for an opened file.

there are two special instances when this is called with an index != -1:

when saving a set and a clip is moved from outside the set to inside it. we need a new handle which is guaranteed unique for the set, but we retain all the other details
when called from get_new_handle() to create the disk part of a clip

otherwise, index should be passed in as -1 (the normal case) – handle will be fetched and a directory created in workdir. – clip_type is set to CLIP_TYPE_TEMP. call close_temp_handle() on it after use, then restore mainw->current_file

function returns FALSE if write to workdir fails.

WARNING: this function changes mainw->current_file, unless it returns FALSE (could not create cfile)

get_new_handle() calls this with the index value passed to it, which should not be -1, sets defaults for the clip, and also sets the clip name and filename. That function should be used instead to create permanent clips.

set performance at right place

these values are only relevant for non-realtime audio players (e.g. sox)

play performance data

if we are opening audio or looping we just play to the end of audio, otherwise...

blank the background if asked to

show the frame in the main window

plug the plug into the playframe socket if we need to

create a separate window for the internal player if requested

needed

this doesn't get called if we don't call resize_play_window()

deinit any active real time effects

stop the players before the cache thread, else the players may try to play from a non-existent file

< necessary

kill the separate play window

or resize it back to single size

create the preview in the sepwin

free the last frame image

disable the freeze key

free any pre-cached frame

pop up error dialog if badly sized frames were detected

end record performance

we got an error recording audio

update screen for internal players

need to do this here, in case we want to preview with only a generator and no other clips (which will close to -1)

re-enable generic clip switching

reset to original value
