de-ip-hdmi's Introduction

de-ip-hdmi

Turn cheap HDMI over IP devices into MKV / JPEG streams for your own personal use!

This tool is designed to target a unbranded set of HDMI extenders that use IP. You can find a write up on this either in blog.md, or on my blog itself: https://blog.benjojo.co.uk/post/cheap-hdmi-capture-for-linux

Usage of de-ip-hdmi:
  -audio
    	Output audio into MKV as well (default true)
  -debug
    	Print loads of debug info
  -interface string
    	What interface the device is attached to (default "eth0")
  -mkv
    	Spit out Audio + Video contained in MKV, else spit out raw MJPEG (default true)
  -sender-mac string
    	The macaddress of the sender unit (default "000b78006001")
  -wakeups
    	Send packets needed to start/keep the sender transmitting (default true)

This tool uses ffmpeg to remux the content, if you don't have that installed then strange things may happen.

This tool also requires root, due to it's use of libpcap and raw sockets to send things.

de-ip-hdmi's Issues

not enough arguments in call to raw.ListenPacket

I am using MacOS Mojave trying to use your package. When I run
go install main.go
All I get is:
'./main.go:256:32: not enough arguments in call to raw.ListenPacket
./main.go:256:38: undefined: raw.ProtocolARP'
I am suspecting there is some problem with my Go installation or PCAP since I am a total noob to Go and programming in general. Can anyone offer some help?

Darker output could be because of gamma getting applied twice ?

Could the darker output be because gamma is applied by the device outputting to hdmi, then once this is used as input, gamma will be applied again before it is sent to output?

How to use

How do I use your tool to capture the video and display in VLC? Your blog says it is possible but there are no examples to show how to do it.

BroadcastWakeups() might not be assembling packet correctly

I don't have the necessary device to test this, but it seems like BroadcastWakeups() might not be modifying the magic packet correctly.

Below the declaration of the magic packet byte slice, the MAC address is written to it, though instead of writing to consecutive bytes, the same byte is overwritten by each consecutive byte in the MAC.

Is this (not) an error?

Streaming to STDOUT remains empty

We're trying to stream the output to ffplay.
However, it seems that the video stream remains empty. When piping the output to a file, the resulting file is empty, too.
Streaming to an MKV fifo works. When starting the program with -debug, there is a lot of output.

I'm not familiar with the code base, but it seems to me that videowriter remains unused when passing -mkv=false.

de-ip-hdmi/main.go

Lines 57 to 61 in 632f157

 go DumpChanToFile(videodis, videowriter) 

 } else { 

 videowriter = os.Stdout 

 }

As a blind guess, I think the line go DumpChanToFile(videodis, videowriter) should actually be placed below the if/else block (line 61).

If this is not the problem, how can we narrow the problem down?

No JPEG data found in image

hey guys,

i have the same issue as mentioned in #5.
both, the deb package and the self compiled binary arent working.

Raspberry compatible - compilation fails?

Hi,

trying to compile it on an raspberry 3. Tho getting following error:

../github.com/mdlayher/raw/raw_linux.go:88:14: f.SyscallConn undefined (type 'OS.File' has no field or method SyscallConn)

Any knows how to fix it?

Clues for device compatibility

This is a brilliant project. I wonder if there is any hint about which chips are supported by this algorithm. That is, compatibility for http://www.ebay.co.uk/itm/121708232481 this one is granted, while there are quite similar devices at http://www.ebay.de/itm//191286580723 or http://www.ebay.de/itm/142015060670 here available in the Germany eBay (way cheaper for me).

Do you have any idea what could tell us about if this program or a similar approach would work before buying such a device?

How to use it for streaming in OBS?

I see you are writing an MKV, but could this be consumed by https://obsproject.com/ ?
Would be great if it is seen as a webcam, as it will be very versatily to be able to do streaming.

Support for lenking 3.0

Does this program support version 2.0 of the lenking or 3.0? 3.0 emits H264 over JPG...

IR over IP support?

I see similar models that support a IR blaster. Do you think it would be possible to send "IR packets" to the blaster? I'm imagining a MythTV DVR setup that would make use of a channel changing script.

i.e. devices like this one https://amzn.com/B00Z9OW6DQ

Incorrect assignment of chunk?

Hi,

I believe that this is incorrect:

    FrameNumber := uint16(0)
    CurrentChunk := uint16(0)

    buf := bytes.NewBuffer(ApplicationData[:2])
    buf2 := bytes.NewBuffer(ApplicationData[2:4])

buf2 should be only 8 bits, consisting of ApplicationData[3].

ApplicationData[2] is set to 0 normally, or 0x80 if it is the last chunk of the frame.

Apologies for not diving in and fixing/testing this, but I'm not a go programmer and I'm working on my own code in python - just passing this on based on my findings there.

Unable to capture output

Edit 4:
On the chance that I do get the glitchy output, it looks like this:
https://i.imgur.com/nXOzjOG.png

I tried mutliple sources.

Edit 3:
Doesn't seem to work anymore, for some reason, not even the glitchy video output.

Edit 2:
Alright, I had to use the Destination ip and port.
"ffplay -i udp://@226.2.2.2:2068" gave me some glitchy video, but it's something.

Edit 1:
On second thought, the packages seem to be MPEG packages actually. But I still can't seem to record or stream them (correctly).

I am using the v0.2 .deb release, having hooked the v2.0 HDMI Extender TX Sender hooked up through Ethernet directly on one of my two Ethernet ports on my motherboard.

Screenshot:
https://i.imgur.com/Y2Chyqb.jpg

The activation trigger activation works, it starts sending out data.
But the de-ip-hdmi program doesn't seem to do anything with it, see the screenshot. (I did hit Ctrl+C after a while)
Nor does Wireshark seem to interpret anything as mpeg packages?

I also tried using VLC during this, capturing a network steam with: "udp://@192.168.168.55:48689", but it doesn't seem to exist.

I might be missing something here, the board I have is identical to the one used in benjojo's blog.

can't build working code

Hi, I'm new to go so sorry if this is a really dumb question, but do I have to do something special to create a binary prog from main.go? I've tried what seems to be the obvious choice: "go build main.go" but the resulting binary executes but doesn't actually work (the sender never starts streaming). The ready built package for Ubuntu/Debian works fine so I know my kit is all wired up correctly...

Can't retrieve video stream

Hello,

Thanks for this tool !
I use a V2 sender and I'm trying to get the video stream in VLC.
