Request for supporting Ceton devices on Linux

[mvallevand]

Sorry I pasted the windows version for the opendct.sh instruction try this instead.

Code:

opendct=/var/opt/nextpvr/scripts/opendct.py                                                                                                                    
python3 $opendct STOP "$2"                                                      
python3 $opendct START "$2" $1 2>/dev/null

That is normal for livetv.  NextPVR seems to be running the command ok.  If you run

/var/opt/nextpvr/scripts/opendct.sh  703 "DCT-Ceton InfiniTV Ethernet (00-80-8d-8a) Tuner 2" /tmp/somefile.ts

Does the file still get created?

Martin

You're onto something - 

Code:

dapharsyde@BonTV:~/recordings$ /var/opt/nextpvr/scripts/opendct.sh 703 "DCT-Ceton InfiniTV Ethernet (00-80-8d-8a) Tuner 2" /tmp/somefile.ts
python3: can't open file '%opendct%': [Errno 2] No such file or directory
dapharsyde@BonTV:~/recordings$ more /var/opt/nextpvr/scripts/opendct.sh
set opendct=/var/opt/nextpvr/scripts/opendct.py
python3 %opendct% "STOP" %2
python3 %opendct% "START" %2 %1  2> /dev/null

I am in linux, so the % convention is probably not used.  Instead I updated opendct.sh to this:

Code:

opendct=/var/opt/nextpvr/scripts/opendct.py
python3 $opendct "STOP" $2
python3 $opendct "START" $2 $1  2> /dev/null

Now when I run the script with arguments, the video file is NOT created, and it just does this:

Code:

dapharsyde@BonTV:~/recordings$ /var/opt/nextpvr/scripts/opendct.sh 703 "DCT-Ceton InfiniTV Ethernet (00-80-8d-8a) Tuner 2" /tmp/somefile.ts
STOP DCT-Ceton
OK
Exit

Notably, the "DCT-Ceton" string is truncated (probably due to the space?)  My bash scripting knowledge is not good enough to fix this

[mvallevand]

Yes if you see my previous post the $2 should be "$2"

Martin

[mvallevand]

Even with $2 in quotes?

Got it, and updated the .sh file.

Things got a little further now, playing a video from the guide shows "Receiving data" and starts counting upwards, but then it dies with "Streaming Failed (transcoder exited)"

Logs attached.

We might have to put a delay in python

in opendct.py

at the top

import time

and insert the wait after

#print("Connection from: " + str(address))
time.sleep(5)

I changed back to DynamicConsumerImpl instead of RawSage, and it works now!!  The RawSage option looks to be creating a file with too much for ffmpeg to handle...

Thanks for all your help Martin!!

[mvallevand]

It probably handles the delay in tuning before streaming starts. Good to know though, thanks for being the pioneer on this. Others won't have to do the testing.

We haven't finished though since we need to do a bit more to get multiple tuners running. I have a modification I made to opendct to support multiple servers, each START opens up a server listener, OpenDCT expected on SageTV server.

Play with this for a while first to see how it meets your needs and then we can move forward if you wish.

Thanks again.

Actually, I did not make any changes with the delay.  The switch back to Dynamic instead of RawSage in opendct.properties allowed the video to be transcoded properly.

Yes I will definitely do some more testing with this.  Is only one tuner supported for now?  After starting a video with the opendct.sh script, will anything issue the STOP command, or does the tuner stay busy?

[dapharsyde]

While testing some other channels, I found one that never tunes in for some reason.

Code:

python3 opendct.py "START" "DCT-Ceton InfiniTV Ethernet (00-80-8d-8a) Tuner 4" 747 /tmp/foodtv.ts
START DCT-Ceton InfiniTV Ethernet (00-80-8d-8a) Tuner 4|747|12345678|/tmp/foodtv.ts|Great
Exit
Traceback (most recent call last):
  File "opendct.py", line 188, in <module>
    main(sys.argv)
  File "opendct.py", line 41, in main
    payload = sendMessage(message)
  File "opendct.py", line 74, in sendMessage
    data = sock.recv(1024)
socket.timeout: timed out

This channel works in mythbackend, so I don't think it is DRM locked or CCI related. Do you know how I could debug this further?
