Stream stops for 1 second with a blue circle in the middle of the screen. #7

Now I switched from Kodi/Tvheadend to roboTV/VDR on my SHIELD TV.

I use roboTV now sice ~1 week and have one small issue. After round about 30-60 minutes I see the "blue circle" in the middle of the screen and the stream stops (pause) for ~1 second. This happens frequntly.

I try to collect some logs when the issue happens next time...

vdr (2.2.0) xvdr (0.9.9 roboTV branch) roboTV (Pre-release) 0.1.0 from your github repo

Many thanks for your effort and the great app!

It's rebuffering data from the server.

Are you connected via WiFi or ethernet ? On an ethernet connection this happens for me sometimes but not frequently. Maybe it's caused by some heavy network traffic. I installed some traffic-shaping rules on my server giving the video packets a dedicated bandwidth.

There are also some issues with the Shield TV on Android L. Hopefully the situation will get better on Android M (to be released soon, ... maybe).

I will release a 0.2.0 version today or tomorrow addressing some audio / video sync problems.

SHIELD TV and VDR server connected over gigabit-ethernet. If i copy a testfile from the fileserver (same system) to the SHIELD TV i have a transferrate of ~80Mbps (9,9 MB/s) which should be suffcient. If I watch TV no other taffic is on the network. I will try some QoS rules on the switch. On the last footballmatch I had it only one time. Not really a big issue. Hope on Android M for SHIELD TV we see some improvements.

Android M is out now for Shield TV. I will observe and report next days if the upgrade helps.

There's still the same issue on Android M. I had to add a workaround for the following unresolved bug: Playback of 1080i channels starts to stutter badly after about ~15 minutes. This doesn't happen on 720p channels. The workaround is to completely reset the decoder. This can cause playback glitches and rebuffering. I''m further investigating on that, ...

I'm pretty sure the blue circle is gone in the 0.4.0 release (for obvious reasons). Unfortunately i had to keep the Shield TV workaround (now I'm pretty sure it's an ExoPlayer issue). I should assemble some testvideos and report this issue upstream.

Maybe libvlc is an alternative player instead of exoplayer.

pipelka commented 8 years ago

I'm thinking about writing my own player based on MediaCodec and MediaSync. It would only implement the things I need (and of course will be much faster, better, ..) ;-) To be honest I already have the skeleton of the player but it needs a bit more time, ...

Until the new player infrastructure is in place version 0.5.1 should perform much better on the Shield TV (with upgrade 3.2)

pipelka commented 8 years ago

Is this really still an issue ?

tunip commented 8 years ago

Never seen this a long time.

pipelka commented 8 years ago

Same for me here. Closing.
