    Some additional information:

    A)

    When watching tv with addon pvr.hts running in the same machine as tvheadend service:

    - LE 11 nightly build - green artefacts; (*)

    - LE 10.0.2 - green artefacts; (*)

    - LE 9.2.8 - ALL OK (no issues).

    (*) If I turn off "Allow Hardware acceleration with DRM PRIME" the artefacts disappear. But image loosed smoothness ...

    B)

    When watching tv by remotely connecting from another machine (windows pc with kodi, or vlc, or android tv with kodi)

    to libreelec tvheadend service:

    - ALL OK !


    So, the issue is common to LE10 and LE11 and ONLY when running pvr.hts in the same machine as tvheadend ...

    and with "Allow Hardware acceleration with DRM PRIME" activated.

    chewitt, popcornmix should I report this somewhere else ?

    thanks

    Some more tests and a sample:

    - Green Artefacts just appearing if using kodi pvr.hts addon viewer and tvheadend server in the same machine (libreELEC 11 in RPi4).

    - Artefacts appearing only after a Continuity Counter Error in tvheadend log;

    - Green Artefacts and Continuity Counter Error DO NOT APPEAR if the viewer is running in another machine (example: VLC in WINDOWS or KODI running from Android tv !

    The link bellow is for a sample file recorded in LibreELEC -> the green artefacts are displayed if played in LibreELEC 11 RPi4, but almost unnoticeable if playing in VLC player in windows:

    Thanks

    Do you see the artifacts in recordings? If so, can you provide a short sample file that shows the issue?

    hi, in recordings they do not appear as green artifacts. anyway I will try to get a sample - more thinking where to share it.

    I had the same issue on a pi3. The issue was that when running both tvh client and server on the same pi AND using advanced deinterlacing method - green artefacts would appear from time to time, also continuity counter errors in tvh log.

    The solution was to use BOB deinterlacing instead of "advanced". However, BOB looks much worse than advanced.

    Another solution was to increase the arm_uc value, e.g.:

    Code
    # vcgencmd arbiter set arm_uc 12 0

    I don't have pi4 so no idea if this would work.

    pi4 using prime for deinterlacing. No options.

    changing arm_uc not producing any changes.

    But thanks for the suggestions.

    I've been using the latest nightly builds on a RPi4.

    Since the introduction of deinterlace for RPi4, it was a big evolution for live tv watching (RE: LE10 & deinterlacing in RPi4)

    I've installed tvheadend server in LE11 and using the tvheadened pvr add-on to watch live tv on my RPi4.

    All ok except ... some green artefacts that appear from time to time in almost every channel.


    I'm using:


    Watching tv in KODI running on libreelec gives the green artefacts.

    As my tv is a SONY Android tv, i've installed KODI 19 in it and connected to the tvheadend server on my RPi with LibreELEC- in this case the image is stable without any artefacts.

    The same goes to the tv provider set-top which also plays flawlessly.

    So, the difference here is KODI20 in LE11 on RPi4 - any suggestions on how to fiddle with LE11 KODI20 to handle those green artefacts ?

    thanks

    Hi had the same issue.

    I've also compiled myself from git and had the same problems.

    In my case kodi was complaining about a missing python lib. (I believe pyhton was updated to 3.9 a couple of days ago).

    Similar to a problem I had reported in another thread,

    I've SOLVED the issue by "make clean" and re-building everything.

    Everything is stable now with the last source versions.

    As I do not know how the nighlty builds are made,

    I humbly suggest to the team to re-build them from scratch.

    [FALSE PROBLEM ---- IGNORE THIS POST]

    well ... drivers are no working anymore.

    I've updated the patch file as the offsets changed (see attach) and it worked for builds compiled with version up to 2nd February 2022.

    After that, tvheadend cannot lock signal.

    dmesg reports errors:

    Code
    si2183 22-0067: err restarting dsp
    si2183 22-0067: err set agc mode
    si2183 22-0067: err set dvb-c mode
    si2183 22-0067: err restarting dsp

    Any help will be greatly appreciated.


    linux-tbs5520se.patch.txt

    I've been using LE 9.2.X for quite some time with ssd access via key pairs.

    I've started some tests with one of the last nightlty builds of LE10, and after following the same steps to activate the usage of the keys as with LE9, ssh keeps refusing the connection with this error reported in journal:

    userauth_pubkey: key type ssh-rsa not in PubkeyAcceptedAlgorithms [preauth]

    Any suggestions ?

    Thanks


    well ... the faster I asked the faster I got the answer 😁

    Anyway, here is the solution to help whoever may need:

    It was just a question of updating putty (the ssh client I use) to the last version (0.77 worked ok).

    Pino GPIO3 (pin 5) --> GND (pin 6)

    add to /boot/config.txt

    dtoverlay=gpio-shutdown


    Grounding GPIO3 starts the clean shutdown process.

    After shutdown, grounding again power on the RPI.

    But .... Librelec will display a confirmation dialog for shutdown.

    To bypass that:

    edit:

    /storage/.kodi/userdata/keymaps/gen.xml

    add:

    <keymap>

    <global>

    <keyboard>

    <key id="61662">Shutdown</key>

    </keyboard>

    </global>


    I believe all this is already in the forum.

    well ... I don't know in fact what to say...

    I understand the difficulties and the need to wait.

    I will probably continue with 9.2.8 in my main RPI4 andm and keep LE10 in the RPI4 testing.

    For movie watching, netflix, tv series, LE10 is just great.

    But for live TV, I've tried to disable DRM PRIME and force (software) deinterlacing, but

    but unless I'm doing something wrong, it is not watcheable

    there's an obvious lag, and probably the RPI4 is not able do do software deinterlacing with 1080i @ 50hz live tv.

    Any sugestions / tweaks ?

    This addon is more than ffmpeg:

    It is a full transcode server with a ready to use configuration and user interface to help you serve your local content to an external device (example: stream from your pi --> ipad on the run).

    It includes ffmpeg and nginx in order to have everything together in just one add-on without external dependencies.

    isn't the included ffmpegx (ffpge-tools) already compiled with everything that it works with rpi transcode ?

    For what I've seen in the past, omx and mmal weren't included.
