No DVB-T2 support with mygica T230c on LibreELEC 9.0.1

1st Official Post

    Hi,

    I am using MyGica T230c DVB dongle using TvHeadEnd on LibreELEC 9.0.1, I am receiving DVB-t broadcasts but I am unable to receive DVB-t2.

    On windows it works using the same dongle and antenna.

    Is it a known issue?

    is there any solution?

    Thanks

    Works fine on RPi3 with exactly the same MyGiga T230c on LE 9.0.1.

    It would help if you could advise what platform you are getting the problem on!

    Are the muxes loaded? or you just can't playback from them

    Either you haven't loaded the DVB module or yor using a very old pre-defined mux

    Please provide URL from

    dmesg | paste and

    Please provide a full debug log.

    How to post a log (wiki)

    1. Enable debugging in Settings>System Settings>Logging
    2. Restart Kodi
    3. Replicate the problem
    4. Generate a log URL (do not post/upload logs to the forum)

    use "Settings > LibreELEC > System > Paste system logs" or run "pastekodi" over SSH, then post the URL link

    Check mux settings in TVH. Need set frequency, bandwidth and delivery system DVB-T2

    Thanks!

    I successfully setup the DVB-t2 MUX(had to manually set params).

    But, now I have problems playing the stream:

    When the client is VLC on windows it works ok but when I am playing locally on LE I have some issues:

    1. every few seconds the sound stops for a short time

    2. audio and video are not synced

    3. the movement isn't smooth

    LE is running on NUC PC (NUC5PPYH), I don't have problems playing other content

    Hi Tomer

    I am facing similar behavior with LE 9.0.1 + TVH 4.2 server running on Rpi2.

    I can guess that you are referring to IL DVBT/DVBT2 muxes which are the muxes that I am referring to.

    I have tried Kodi HTSP clients on various platforms (Windows, Android, Android TV) and with two type of DVB USB dongle (T230C and XBOX ONE tv device), and they are all playing the IL DVBT mux fine while DVBT2 mux is played with the same effects you have described.

    I have tried other (than Kodi) clients on the same platforms (TiViMate, TVirl, TVHClient, VLC,...) and they all play the DVBT2 mux with no such effects, but they are all using use TVH 'pass' profile for streaming !

    So, I assume that the problem is related to the fact that Kodi HTSP client is always using 'htsp' streaming profile. I have tried setting it to use other profiles but looking at Kodi logs, it seems it always use 'htsp'.

    I don't know whether the problem is with:

    1. The DVBT2 mux

    2. LE TVH server

    or

    3. Kodi HTSP client

    If someone on this forum can investigate the mux data, I can provide a recording of the mux.

    Maybe H.265 HD channels ?

    I think it is H.264. Mediainfo reports for the first video channel in the transport stream recording:
