livetv - unable to seek

[Markus Schulz <msc@…>]

to reproduce:

• start livetv
• press pause
• wait until the current show is over (backend switched to next recording)
• no try to seek forward the show (until next show)

...you can't seek, only the first 2-3 steps are working, then steps forward without go forward.

log for a single step:

additional:
if you play until next show, you can seek again normally.

This is a major annoyance IMHO, since there is another related issue that occured to me the other day: When trying to seek backwards near the end of a time-shifted show (missed something, wanted to see the last scene again), it did no jump back the epected 10 seconds, but to a position close to the beginning of the show. Since seeking forward does not work in 0.24, it was then impossible to view the end of the show, unless I had been willing to watch it _again_ from the beginning, this time careful to not touch the seek buttons.

This is not Ubuntu, this is not the place to talk about your feelings. This is a bug tracker. Please read the ticket howto.

fix for livetv seeking problems when program transition occurs

[tralph]

Markus, please try the attached patch and let us know if it helps or not. It's against master but should be easy to apply to -fixes as well.

tralph,

... also ensure not return -1 when jump to next is not in order, eg:
