CEC HDMI functionality ..not work

[Tim Curtis]

I'm not sure what that user installed but the HDMI CEC feature included in moode uses the built in Linux kernel based CEC functionality. The command cec-ctl is used. There is nothing else that has to be installed.

Here are the code blocks

/var/www/daemon/worker.php

Code:

//----------------------------------------------------------------------------//
workerLog('worker: --');
workerLog('worker: -- Startup complete ');
workerLog('worker: --');
//----------------------------------------------------------------------------//

// Turn display on
if ($_SESSION['hdmi_cec'] == 'on' && $_SESSION['localui'] == '1') {
    if (file_exists('/sys/class/drm/card0-HDMI-A-1/edid')) {
        $drmCardID = 'card0-HDMI-A-1';
    } else if (file_exists('/sys/class/drm/card1-HDMI-A-1/edid')) {
        $drmCardID = 'card1-HDMI-A-1';
    } else {
        $drmCardID = 'undefined';
    }

    if ($drmCardID != 'undefined') {
        sysCmd('cec-ctl --device=0 --playback "--phys-addr-from-edid=/sys/class/drm/' . $drmCardID . '/edid"');
        $cecSourceAddress = trim(sysCmd('cec-ctl --skip-info --show-topology | grep ": Playback" | cut -d":" -f1')[0]);
        sysCmd('cec-ctl --skip-info --to 0 --active-source phys-addr=' . $cecSourceAddress);
        sysCmd('cec-ctl --skip-info --to 0 --cec-version-1.4 --image-view-on');
        workerLog('worker: HDMI display:     drm-card=' . $drmCardID . ', cec-source-addr=' . $cecSourceAddress);
    } else {
        workerLog('worker: HDMI display:     drm-card=' . $drmCardID);
    }
}

/var/www/daemon/watchdog.sh

Code:

wake_display () {
    WAKE_DISPLAY=$(sqlite3 $SQLDB "SELECT value FROM cfg_system WHERE param='wake_display'")
    if [[ $WAKE_DISPLAY = "1" ]]; then
        cec-ctl --skip-info --to 0 --cec-version-1.4 --image-view-on
        export DISPLAY=:0
        xset s reset > /dev/null 2>&1
    fi
}
