#9341: H264 doesn't play back watchably on Windows frontend
-------------------------------------------------+-------------------------
Reporter: Jerry Rubinow <jerrymr@…> | Owner: nigel
Type: Bug Report | Status: new
Priority: minor | Milestone: unknown
Component: Ports - Windows | Version: 0.23-fixes
Severity: medium | Keywords:
Ticket locked: 0 |
-------------------------------------------------+-------------------------
When playing back a 720p 60fps H264 recording on a Windows frontend with
ION video, I get lots of pauses in the video. Playing back a 720p 60fps
MPEG recording, there are no pauses. The H264 is from an HD-PVR with
default bitrate setting and the MPEG is from an HDHR. In both cases, CPU
usage for mythfrontend, according to Task Manager, is in the 30% to 40%
range. Using Direct3D for playback, no filters.
To eliminate potential network issue, I created a Videos directory locally
and copied the recording there, but it still had the pauses. I tried
muting sound to eliminate audio issues, problem still exhibited.
Log of session attached, session consists of starting up mythfrontend with
-v playback,timestamp, starting playback of video, waiting long enough for
the OSD to go away and observe pauses happening, and then exiting.
mythfrontend --version output:

Let me know if I can provide any other info.
