Summary0000104: "Delay playback start until render queue is full" fails when toggling subtitles off/on quickly
DescriptionToggling subtitles off/on quickly in the splitter with "Delay playback start until render queue is full" enabled can occasionally cause madVR render queue to fail to fill, leaving the media player in a paused state.
Steps To ReproduceEnable "Delay playback start until render queue is full" in madVR

Open MKV video with a single embedded text subtitle track.

Press "s" in MPC-HC twice quickly when a subtitle line is being displayed, to quickly toggle subtitle off/on in the splitter.

Upon pressing "s" the second time, madVR's render queue fails to fill from 0, leaving MPC-HC in a paused state.

If unable to reproduce, try a different video. For reasons unknown, difficulty reproducing this bug can vary based on the sample.
Additional InformationThis bug occurs even when no subtitle renderer is present in the graph.

This bug occurs in media players other than MPC-HC as well.

This issue does not seem to occur when using Haali Splitter, which suggests a possible LAV Splitter bug.

Haali Splitter seems able to enable/disable the subtitle track within a split-second, even when "Delay playback start until render queue is full" is enabled.

Lav Splitter on the other hand seems to take up to 2 seconds to either enable or disable the subtitle track when "Delay playback start until render queue is full" is enabled.

Should be fixed in v0.87.9. I hope the fix will have no side-effects. We'll have to see about that...
