Slow / delayed resume after skipping while paused

[cncb]

I've made a slight tweak to the next release to try to align seeks to just before start start of an iFrame. It doesnt really seem to make much difference, but it might help.

I look forward to trying the next release; I've long believed skipping to I-frames would improve matters.

I don't pretend to exactly know what you guys are talking about but I look forward to trying it out and hope it might provide some improvement. I don't suppose you are willing to disclose when we might be able to try it? Thanks.

The next release will probably be a week or two away.

Just installed 2.2.6
Skipping during pause is working really well, but there is still an unacceptable delay (210 seconds) before play will restart.

I spent a day looking into it but was unable to determine what was causing it, so nothing has changed on this front. It's on my list to revisit when I've got some more available time.

Below is from the NPVR.log covering pause being pressed at 16:50:00, skip pressed once at 16:50:10, play pressed at 16:50:30.
Play actually resumed at 16:53:25

I don't pretend to exactly know what you guys are talking about but I look forward to trying it out and hope it might provide some improvement.

Unfortunately skipping ahead is still painfully slow for me even with the changes in 2.2.6. I am using the built-in Intel Sandy Bridge graphics for several client PCs and an older Clarksdale graphics for the server and they all exhibit the same sluggish behavior. Do you think there is any hope for improving this or is this just how it is?

Bummer.

Hopefully - I'm always trying to improve things. Its hard to know up front how much success I'll have. I definitely intend to revisit skipping, since I've still got the original problem mentioned from this thread (ie, skipping while paused).

Is skipping in ts files harder than in ps (mpg or dvr-ms) files? PVRX2 definitely has faster/smoother/better skipping for me than NPVR. In PVRX2 I record QAM with the dvr-ms mux and remux the firewire stream using the ATI mux.

It uses different directshow components, and the behavior is just different.

For the firewire side if you are using the NPVR TS write could you compress and upload the Timing.Info file To get this file use

more < filename.ts:Timing.Info > Timing.Info
