Slow channelchange on AFN powervu

[stemkow]

With oscam-emu Emu r764 - Add PowerVu hash mode 4 and oscam http://www.streamboard.tv/svn/oscam@11392 channelchange is very slow (10 seconds) on afn powervu.

I have tracked the problem down to module-dvbapi.c line 4454. Channel changing speed is greatly improved when removing " || pvu_skip". I am not sure if this is a good fix and it may cause problems on other powervu channels. However, it works for me and it helps pinpoint the problem

Which box and image? Have you tried increasing the delayer option in dvbapi to see if this helps?

Can you post a livelog with and without the pvu_skip in the code?

I don't have this problem. My box zaps normally. In addition, this "pvu_skip" is in the code for a very long time and none has ever said anything about slow zapping.

This with latest tvheadend. I use oscam.net protocol >=10389. CW mode: standard/auto
oscam.delayer was set to 60 ms.

The two log files are attached. This is from an experiment where I tune to one afn
channel. As soon as there is picture I tune to a second.

I would suggest to ask the tvheadend developers.

@stemkow @wphilips is this issue still present?

Can you provide new logs with latest emu (no need to use cacheex for afn now) and with debug level 2+128.

I performed an experiment with oscam 11438 and oscam emu 9bc5fdf Emu r782.
Channel change os about 6-8 seconds. With pvu_skip commented out, it is about 2 seconds.

Logs are attached
