Previously, audio was all queued first and would therefore all have to
finish before any video frames could start caching. No longer! Now they're
queued side by side so users won't have to wait for audio to finish before
their cached frames come in.
These are two changes that speed up when frames start getting rendered
and processed (particularly for larger scale projects):
* Sorting of time beforehand was done to optimize decoding but is actually
unnecessary since the frames are already sequential when they're retrieved
from the range. As long as we maintain that order, no sorting is required.
This speeds up caching IMMENSELY.
* Evaluate hashes concurrently while retrieving frames. Before, this was
done before any rendering and could therefore delay rendering by several
seconds. Doing them concurrently means frames start rendering almost
immediately and further hashes can be analyzed while we wait for frames to
finish rendering.
Implemented a smarter auto-cache that's context sensitive. Caching will
automatically pause when playback begins or values are being changed and resume
when inactive.
Made various changes and fixes to the task system:
- Tasks are built around QtConcurrent rather than QThread. Reduces
code complexity significantly.
- Task error reporting is now streamlined in both TaskManager and
TaskDialog.
- Moved ProjectImport/Save/LoadManager to the app/task folder
