#4864 closed defect (wontfix)

Streaming recordings over wifi no longer works

Reported by: john.baab@… Owned by: Isaac Richards
Priority: minor Milestone: unknown
Component: mythtv Version: 0.21-fixes
Severity: medium Keywords: wifi backend
Cc: Ticket locked: no

Description

While streaming recordings from one backend to another with MythTV over 802.11g wifi, skipping occurs in the 0.21-fixes branch.

Snippet from mythfrontend.log: 2008-03-04 21:23:14.712 NVP: Prebuffer wait timed out 10 times. 2008-03-04 21:23:16.067 NVP: prebuffering pause

This didn't happen in the 0.20-fixes branch. If I mount the recordings in an nfs share over the wifi instead of letting MythTV share them out then the problem goes away.

I'm experiencing the same problem on the development trunk. The issue occurred within the past two weeks. I haven't identified exactly which update caused the problem.

Replying to lstein@cshl.edu:

I should add that the prebuffer pauses occur only when streaming a pre-recorded HD show. Watching live HD shows does not cause the problem. The prebuffer pauses are very frequent and render the shows unwatchable. Switching to NFS essentially eliminates them, but there are still rare prebuffer pauses during periods of high network activity (which is why I went to "always stream" in the first place).

These are DVB-recorded shows and are not transcoded, so there should be no difference in bitrate between live and prerecorded.

heh, just use NFS if it works for you, it has always had better performance for me. The streaming was re-engineered in 0.21 to work better for more people, but of course some marginal networks with at some bit-rates were negatively affected as the buffer and block sizes are not exactly the same.
