HDMI to USB grabber

[mvallevand]

Just to finalize things neither of these work?

Code:

ffmpeg -f dshow -s 1280x720 -i video="USB Video":audio="Digital Audio Interface (USB Di" -vcodec h264 -acodec aac -f mpegts -| ffplay -i pipe:
ffmpeg -f dshow -s 1280x720 -i video="USB Video":audio="Digital Audio Interface (USB Di" -vcodec h264_qsv -acodec aac -f mpegts -| ffplay -i pipe:

Sorry Martin, none of them works. Anyway thanks for your time. BR.

That's too bad I just pulled mine from my linux box and it worked like I expected.

Code:

ffmpeg -f dshow -s 1280x720 -i video="USB Video":audio="Digital Audio Interface (USB Digital Audio)" -vcodec h264_qsv -acodec aac -f mpegts - | ffplay -i pipe:

Anyway my HDPVR is much better.

Hello there,
I've just got my HDPVR Rocket and again face problems to add a channel to nextpvr.
I found this wiki here: https://forums.nextpvr.com/showthread.php?tid=59913
Even with these steps I get "This device currently has no channels, hit the Scan or Import buttons to add channels to this device. "
Maybe someone can push me in right direction...

You need to first add an XMLTV or Schedules Direct EPG source (step 17 on that link) before adding an HDPVR device. If you need more support open a new thread to keep this on on topic.

Looking for some help in setting up one of these USB HDMI capture devices.  I created a .bat file to handle blasting the IR to change the channel and then using ffmpeg to encode the stream.  Here is what is in my .bat file:

Code:

"C:\Windows\SysWOW64\wscript.exe" "C:\ProgramData\LM Gestion\LM Remote KeyMap\plugins\GBPVR\GBPVR.wsf" "Cisco Explorer 4642HD" %1

ffmpeg -f dshow -rtbufsize 100M -video_size 1280x720 -framerate 60.0002 -i video="USB Video":audio="Digital Audio Interface (2- USB Digital Audio)" -vcodec h264 -acodec aac -f mpegts -| ffplay -i pipe:

When I run this in Windows Command line, it works fine.  The channel changes, and the video processes and shows up.  When I set it up in NextPVR and use the web interface to select a channel, I can see the IR blaster go off, but then I get a message that says "Starting device, please wait..." followed by "Streaming failed (transcoder exited)".  What have I done wrong?  I'm coming from v4, and slowly trying to convert to v5.  So some of this is still new to me.  Please advise.

Assuming you are going this in a batch file did you test the batch file as well

grabber.bat 123 | ffplay -i pipe

It the batch fails make sure you have the path to ffmpeg specified and you batch file stops at the dash (remove " | ffplay -i pipe:")

If it works upload our extra xml file.

Originally when I was testing, I tested the batch file with "| ffplay -i pipe:" included in the file, and called usbcapture.bat 123, which worked.

If I remove "| ffplay -i pipe:" from the batch file and call "usbcapture.bat 123 | ffplay -i pipe:" from Windows Command Line, I am getting errors:

Same thing occurs whether I call ffmpeg or the full path "C:\ffmpeg-2020-11-22-git-0066bf4d1a-full_build\bin\ffmpeg.exe"

I've attached the .bat file and the .xml as well as my logs.

The exras file is bad you don't need ffplay in it either. Make the change delete the channels from the extra with the trashcan and rescan

Code:

<args>/c C:\Users\Public\NPVR-data\USBCapture.bat {channel}</args>
