Custom HDHR Extra

[VCR58]

Sorry, I read .py instead of .sh

Live TV is working now with the EXTRA devices.

Did you see how to use the transcoding options? It won't help much until sub supports smarter transcoding and I am not sure if there is a use case but since I was doing this for ATSC 3.0 I figure someone could modify the script and let ffmpeg transcode audio and have the device do h/w transcoding.

I have no clue how to use the transcoding options. I new this device had hardware transcoding built in but never knew what to do with it. The HDHR web gui shows different options to choose from. Here is a screen grab of it.

If you note in my script I show the options you just append them to $1 You can do this on the fly after each run to compare them.

Ok I see.

I tried a couple different settings but could not tell any difference in the quality. 

I'll mess with it some more.

I have been doing some reading about the HDHR extend because I wasn't clear what the transcoding feature does and how to test if it is doing what it is commanded to do. I found this PDF https://www.silicondust.com/hdhomerun/hd...opment.pdf which explains what the different transcoding settings do.

So, if I enter transcode=internet240 in the shell script, this should be the lowest quality setting. From the PDF document this is what it says...

"internet240: transcode to low bitrate AVC progressive not exceeding 432x240 30fps for 16:9 content, not exceeding 320x240 30fps for 4:3 content"

Then if I run the .py script and watch a TV channel using the EXTRA tuner device, I should see the bitrate limited to the "Internet240" rate.

Am I reasonably close to a correct assumption?

Also, would Kodi tell me what the bitrate is? Or maybe the NextPVR logs would tell me?

The python process is run once to create the extra. After that you just need to edit hdhrconnect.sh/.bat to run do what you want. You need ? before transcode.

Yes Kodi O key tell you the resolution on a tab. The web browser logs will tell you as well.

Right like I posted I didn't include the scripts.  For linux add this to scripts/hdhrconnect/hdhrconnect.sh and set it chmod +x for all users

Code:

if [ "$2" == "--pass" ]; then
        #Extend devices can add a profile here ?transcode= and an option
        #rem heavy, mobile, internet540, internet480, internet360, internet24
        echo "$1"
else
        acffmpeg -re -v panic -i "$1" -vcodec copy -acode ac3 -f mpegts -
fi

When I ran hdhrconnect.sh I got an error

Code:

/bin/bash hdhrconnect.sh
hdhrconnect.sh: line 7: acffmpeg: command not found

This is the shell script I have...

Code:

if [ "$2" == "--pass" ]; then
        #Extend devices can add a profile here ?transcode= and an option
        #rem heavy, mobile, internet540, internet480, internet360, internet24
        ?transcode=internet240
        echo "$1"
else
        acffmpeg -re -v panic -i "$1" -vcodec copy -acode ac3 -f mpegts -
fi

I only provide the special ffmpeg ATSC on demand but no HDHR users seem interested.

However you are testing it wrong, and you have the wrong syntax, it would be echo "$1?transcode=internet40" the test from the Extend would be

./hdhdconnect someurl --pass

Ok, I believe it's working now after correcting the sytax. I still get the "command not found" error, but when I run the shell script and select the channel that uses the Extra device Kodi reports the video decoder changed to the h264 profile.

Thanks.
