I reported the regression upstream Aw: Re: dvb usb issues since kernel 4.9 — Linux USB

Could you please follow/join the conversation and maybe provide further information ([email protected])?

Alan Stern had the following questions:

It would be good to know what hardware was involved on the x86 system
and to have some timing data. Can we see the output from lsusb and
usbmon, running on a vanilla kernel that gets plenty of video glitches?

Overall, this may be a very difficult problem to solve. The
4cd13c21b207 commit was intended to improve throughput at the cost of
increased latency. But then what do you do when the latency becomes
too high for the video subsystem to handle?

Great work jahutchi!

I've uploaded #0101z builds of master and kernel 4.14.10 with the the 4cd13c2 commit reverted:

RPi / RPi2 / Generic

RPi2 build works for me too. Thanks again to all involved!!

Thanks jahutchi for your investigation.

Maybe milhouse could make a current test build with this commit reverted?

any progress? just tested latest kernel 4.13.12 on x86 +S950 and it's still affected

Looks like it's I/O dependent: the problem manifests after tens of minutes when just displaying DVB stream (cca 90mins) but with heavy disc I/O in serveral minutes...

EDIT: reported upstream: 197835 – DVB-S discontinuity, PES packet size mismatch, stream corruption

Confirmed, any progress here?

I could test builds on rpi3.

My dvb card is technotrend s2-4600.

Could someone tell me If its possible and how to install this builds on emmc on rock64?

your are right, errors are still there for me too on rpi3.

I had 2 recordings today without errors, so I thought the issue is gone but in the third recording there are errors again.

Sorry for the noise.

Hopefully you'll find the harmful commit.

I think there's improvement with kernel 4.14.6

yes tested it but didn't get it working (also not at raspbian) so I guess it is still broken

Thanks for testing - would you add a comment to the tvh ticket Feature #4572: OMX Support - Tvheadend

I need to find my RPi to make some screens

Basically you have to go to the transcoding settings, create an new transcoding profile with mmal, create an NEW streaming profile and use the transcoding profile you made.

Did you have time to test and some documentation?

thanks for your efforts.

Very sad that there's no progess since about a year now.

I already tried that, but I always get errors when I open livetv window and than select the new streaming profile.

screens would be of great help.

Could you please explain how to set up hw-transcoding in tvh on rpi?

I'm considering to buy a rock64, could someone test uhd livetv with high refreshrates 50/60 hz?

I know about the limitations, so I was surprised to read it's possible to stream 4 hd channels on rpi2.

Which kernel are you using on rpi2? You don't have discontinuity errors in tvheadend with latest kernels?

Quote from phaze75

Ok, thanks for the info and the manual updates!

Did you get omx transcoding to work with latest build?

last working build 1002
UOMe

non working build 1005

AWUP

I also have no captions in this build, only the icons are shown.
