|0000104||madVR||bug||public||2013-07-08 07:26||2014-04-01 23:15|
|Platform||x64||OS||Windows 7 SP1||OS Version||7601|
|Summary||0000104: "Delay playback start until render queue is full" fails when toggling subtitles off/on quickly|
|Description||Toggling 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 Reproduce||Enable "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 Information||This 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.
