playback_trace.py — Always-on playback transition logger.
|
|
|
|
Kivy's log level is forced to 'warning' in main.py / run_win.py, which
|
|
suppresses every Logger.info()/Logger.debug() line. That made it impossible
|
|
to see why the player skips/crashes at the weblink->image and video->next
|
|
transitions.
|
|
|
|
This module writes a plain-text trace file (logs/playback_trace.log) with
|
|
timestamps, INDEPENDENT of Kivy's log level, so we can always see exactly
|
|
what the player is doing. It is thread-safe (a lock guards the append) and
|
|
never throws (all failures are swallowed) so it can never break playback.
|
|
|
|
Usage:
|
|
from playback_trace import trace
|
|
trace("play_current_media", index=3, name="foo.jpg", type="image")
