Timeshift in radio mode

Richard Bialek

Hi all!
Since I didn't find any ticket or forum entry here: I've recently found out that timeshift on radio channels seems to be not working as expected. I am on 4.2.8-dmo1 on Debian's Buster.

I would expect that it works like on a tv channel but actually it allows me to pause but neither back/forward seeking nor going back to live are possible.

Is this a known issue or maybe am I missing some hidden config option?

Regards,
Richard

Updated to 4.3-1917~gecd05a21d~buster but still am not able to seek while in radio mode.

Richard Bialek

Since I still have that problem on newest version (4.3-1919): does it work for anyone?

Saen Acro

Post bug report.

Richard Bialek

In the meantime since I had another problem with the EPG grabber I'm back on the 4.2 branch. So don't know if it's clever to post a bug without having possibility to check possible solutions if they would work.

Dennis K

I stumbled upon the same issue and ask myself, if it is even possible to use timeshift for radio. I am using the following build together with pvr.hts on Kodi and LibreElec nightly: HTS Tvheadend 4.3-2175~gd85c957aa
I also asked in LibreElec forum, with no answer so far: https://forum.libreelec.tv/thread/27773-pvr-hts-timeshift-for-radio/ I would be happy to find out, if timeshift with radio is possible, and if not, how that could be accomplished. Thanks and best!

Jonas Lang

How are you testing Timeshift on Radio. Are you using a 3rd party client/frontend to do your testing.

Dennis K

Yes, I do. As I said in my post, I am using KODI and the TVHeadend Addon pvr.hts. I don't have anything else to test timeshift. The Android client TVHClient doesn't support timeshift at all. Is there any other player I could test with?
What seems to work is the web player of TVHeadend. However, as the UI of the web player is very limited, I cannot see what happens, when I press pause. Also, as there are no buttons for forward or rewind, I cannot really test. Just by listening after having paused for a couple of minutes, it seems, that the web player supports timeshifting as it starts to play again at the position where I pressed pause. Only guessing here.

Jonas Lang

That’s really a job for the guys at Kodi.

I'm not entirely sure what you mean by timeshift. But FWIW I use vlc to play programmes and it behaves the same for TV and radio. You can change speed of playback, you can move the slider from one place (time) to another, forwards or backwards etc etc. So I don't think there's a problem.

TVH just stores .ts files so interpreting the playback of those files is down to the player, as Jonas said.

Enabling Timeshift in TVH will allow the user to Pause/FF/Rewind in the Kodi Live TV PVR. He’s stating it works for TV and not for Radio so I imagine it’s an issue with Kodi and it’s addon and how it handles audio streams and not with TVH. There’s plenty of muscle over in the Kodi forum who I imagine would be only too glad to help resolve his issue.

Jonas Lang

Interesting Kodi blame TVH for this situation https://forum.kodi.tv/showthread.php?tid=375590

I suggest filing a bug here in TVH. https://tvheadend.org/issues?per_page=50.

Dennis K

Thank you, Dave H for clarifying. Not being able to Pause/FF/Rewind during listening to a radio channel is exactly my issue.
Thank you, Jonas Lang, I opened an issue on the bug tracker of TVHeadend. Let's see, what they think about it and what further info they may need.

Dennis K

This is fixed now, thank you very much flole998! See https://github.com/tvheadend/tvheadend/issues/1604
