|Status||closed||Resolution||unable to reproduce|
|Platform||x86-64 (Intel Core i3 M 330)||OS||Windows 7 Ultimate SP1 64-Bit||OS Version||6.1.7601|
|Summary||0000244: 10-bit / 8-bit color-depth change freezes rendering|
|Description||I have a rendering problem that seems to be cause by a 10-bit / 8-bit video playback transition.|
In the DirectShow graph: LAV S/A/V, xy-VSFilter 22.214.171.124, madVR, Default DirectSound Device.
Files that I noticed the issue with are each:
* Matroska v2 with ordered chapters:
ch.1: 10-bit, AVC L4.1, YUV 4:2:0, 23.976P, SAR 1:1, 1920x1080 (main file)
ch.2: 8-bit, AVC L4.1, YUV 4:2:0, 23.976P, SAR 1:1, 1920x1080 (external file)
ch.3: 10-bit, AVC L4.1, YUV 4:2:0, 23.976P, SAR 1:1, 1920x1080 (main file)
Video stream rendering freezes on the last frame of ch.1.
|Steps To Reproduce||Play a file with described characteristics, possibly any MKV with ordered chapters that switch between 10-bit and 8-bit, or maybe any video stream of any kind that makes that transition.|
|Additional Information||With some madVR settings, I see the last frames of ch.1 (sometimes terminated with a green-frame) displayed in a repeating loop instead of a static image of the last frame. (I believe this is setting dependent, but I am not sure what settings; possibly buffer sizes.)|
I can work around the issue by seeking past the 8-bit segment before it's playback is attempted.
After playback freezes during the 10-bit to 8-bit transition, playback of audio continues without issue. madVR seems responsive (for example if I press Ctrl-J the OSD info is toggled, although it may introduce a green-frame artifact flashing if it was not already present).
Also after playback freezes, it does not unfreeze on its own when the 8-bit segment is over or if I seek to the initial or final 10-bit segment manually.
The OSD, if displayed, does not seem to indicate any problems.
Ctrl-A (reload file) in MPC-HC allow the file to play again from the start.
I tried all the other renderers available in MPC-HC, with the same splitter and decoders, and each of the other renderers played through the 10-bit/8-bit transitions without issue.
Thank you for your work on this state-of-the-art video renderer!
