• TVheadend on Raspios HD issues

    Further joys of exploring a Pi 4B with a TV hat on have proved frustrating

    I ported my TVheadend server configuration to it and that worked fairly
    OK except when I popped a TV Hat on it that was allegedly capable of
    doing HD TV.

    Well out of the box it didn't, but web searches eventually got me to the
    stage where the HD channels were recognised, but they show no EPG data,
    and when streaming, there is no sound.

    It does show 139% CPU usage too, in 'top' but seems to play ok

    The suggestion is that the transcoding from HD LATM to web-vorbis-vp8
    protocol (the only one that has ever worked on the software: the others
    either don't work or crash the server with what look like out of bound
    memory accesses) needs something more than the current issue.

    Anyone have any klews on this?

    streaming to local HDMI display, or over LAN to VLC?

    if the latter, it's not unknown for it to pick the wrong audio track,
    how many different ones do you see?

    Neither. Over lan to browser via custom server

    I'll try and see. VLC is happy to play a *recorded* HD though.

    Hmm. celluloid is happy to play it but the profile is 'pass' which does
    no transcoding.
    I'm trying to get it to play in a browser...browsers don't understand
    raw TV streams

    So it needs transcoding

    I think mine does live transcoding (certainly more buffering that using
    VLC) it can still get the audio track wrong ... just tried and I was
    getting the audio description channel instead of "normal" channel.

    Works, but that is passthru and it invokes 'celluloid'

    I've not had that at all. The logs show the correct audio channel is
    being transcoded, but no sound emerges :-(

    I can get neither sound NOR EPG out of the 682MHZ Mux.

    TVheadend can play channels in the MUX in passthru mode, but not when transcoding
    TVheadend has never managed to get EPG data from that MUX, ever.

    Seems your TVH is unsure about AAC-LATM and MPEG2AUDIO audio, mine gets
    AC3 and is happy with it?


    Its AAC-LATM that seems to be the issue. And the lack of EPG for the
    channels.

    Well I can do HD TV in other ways if I really need it by using (one of
    the) the TV headend native interfaces.

    One works, the other has no sound...
