Schalten Sie den Fernseher mit Cec-Client auf RPI

Question

Ich habe RPi B + läuft Raspbian mit meinem LG TV über HDMI verbunden. Ich succefully zusammengestellt und cec-Client installiert und ich kann easly einschalten TV mit dem Befehl echo "on 0" | cec-client -s, aber wenn ich versuche, Fernseher auszuschalten mit dem Befehl echo "standby 0" | cec-client -s ich diese Ausgabe erhalten:

und nichts passiert. Ich benutze auch nur CLI, und nach einiger Zeit bringt RPi das Fernsehen in einen leeren Bildschirmschoner, aber ich kann mir nicht vorstellen, wie ich das sofort auf meinem Kommando machen kann.

Answer 1

Es scheint, dass mit libCEC nichts falsch ist. Allerdings ignoriert die HDMI-CEC-Implementierung des LG TV-Modells möglicherweise nur den Standby-Befehl. Sie sollten Ihren Raspberry Pi mit einem anderen HDMI-CEC-kompatiblen Gerät testen, um zu überprüfen, ob der Standby-Befehl ordnungsgemäß funktioniert. diese

Verwendung:

sudo apt-get update; 
sudo apt-get install gcc; 
sudo apt-get install autoconf; 
sudo apt-get install libtool; 
sudo apt-get install pkg-config; 
sudo apt-get install libselinux1-dev; 
sudo apt-get install liblockdev1-dev; 
sudo apt-get install gawk; 
sudo apt-get install g++; 
sudo apt-get install c++; 
sudo apt-get install libgudev-1.0-dev; 
sudo apt-get install libudev-dev; 

mkdir -p $HOME/distr/libcec; 
wget -P $HOME/distr/libcec https://github.com/Pulse-Eight/libcec/archive/master.zip; 
unzip $HOME/distr/libcec/master.zip -d $HOME/distr/libcec/; 
cd $HOME/distr/libcec/libcec-master ./bootstrap;" 
./configure --with-rpi-include-path=/opt/vc/include --with-rpi-lib-path=/opt/vc/lib --enable-rpi; 
make; 
sudo make install; 
sudo apt-get install cec-utils; 

Dann folgt aus:

sudo apt-get update 
sudo apt-get dist-upgrade 
sudo rpi-update 
sudo reboot

LG-TVs (und nur TV) nicht unterstützt CEC Standby command.See here. Ich weiß nicht, ob es libcec-Implementierung ist oder es ist TV-Beschränkung
