Jumpy Fast Forward and Rewind

[Don Pedro]

Hello!

Dunno if this is related to XBian, Kodi or the tvh plugin!

• I'm on a Raspi-3 with Kodi 17.6 on the current XBian.
• However the problems were already present with Kodi 17.2 and higher, there they were even much worse.
• Video codecs/licenses are installed.
• I'm using the tvheadend backend to stream from a tvheadend server (x64 Debian, hexacore machine).
• I tried TS and MKV format on the server, no difference.
  

Is anyone experiencing the same problems:
During playback of a video I'm trying to FF or rewind the video (e. g. skip some recorded ads). This functionality is somewhat "jumpy", means the cursor is e.g. advancing several 30s but then unexpectedly jumps back to the position I started from (mostly when releasing the FF-key). You can hardly navigate to a specific position, as it's always jumping back towards the old start position of the FF. Rewind is equally misbehaving.
If on the contrary I pause the video prior to FFing/rewinding things behave more or less as expected. So I suppose the advancing of the running stream is somehow interferring with the FF/rewind algorithm, yielding this annoying behavior.

BTW: The FF/rewind function is not very comfortable, dunno if anyone already mentioned that! Nice would be to increase/reverse the playback speed instead of jumping a couple of seconds ahead/back, yielding a much better FF-experience as many may know it from old VCR's and stuff. Are there reasons why this is not possible?

Regards

Don
