SPDIF to 5.1 software loop decoder. Use if you want to connect a digital surround signal (Dolby Digital), such as an Xbox 360 S or TV, via your PC to your 5.1 (analog) stereo. Like a digital receiver/decoder, just in software.
FFMPEG is licenced under the GNU Lesser General Public License version 2.1 and so is this piece of software.
- libasound2-dev
- libao-dev
- cmake
- ffmpeg (tested with 4.3.1)
Prepare CMakeLists.txt - set FFMPEG Var with Path to ffmpeg (if not in ../ffmpeg-4.3.1)
cmake .
make
./configure --enable-shared --disable-static --disable-everything --enable-demuxer=spdif --enable-decoder=ac3 --enable-indev=alsa
make
I run it like this:
./spdif-decoder -i hw:CARD=Device -d pulse -o alsa_output.usb-0d8c_USB_Sound_Device-00-Device.analog-surround51
Alsa's hw:CARD=Device
is my SPDIF input. You can list your alsa devices with
aplay -l
I had to use amixer
to set the capture source to SPIF. In this case
Device
is the alsa name of my SPDIF-in card:
amixer -c Device scontrols # show controls
amixer -c Device get 'PCM Capture Source' # show options
amixer -c Device set 'PCM Capture Source' 'IEC958 In' # set input
