# rpidatv
|
||||
**rpidatv** is a digital television transmitter for Raspberry Pi (B,B+,PI2,PI3,Pizero) which output directly to GPIO.
|
||||
*(Created by Evariste Courjaud F5OEO. Code is GPL)*
|
||||
|
||||
<h1> rpidatv Transmitter installation </h1>
|
||||
```
|
||||
sudo apt-get update &&
|
||||
sudo apt-get install rpi-update &&
|
||||
sudo rpi-update &&
|
||||
sudo apt-get install apt-transport-https &&
|
||||
sudo apt-get install git &&
|
||||
git clone git://github.com/f5oeo/rpidatv &&
|
||||
cd rpidatv/src &&
|
||||
make -j 4
|
||||
sudo make install
|
||||
# Installation
|
||||
```sh
|
||||
$ wget https://raw.githubusercontent.com/F5OEO/rpidatv/master/install.sh
|
||||
$ chmod +x install.sh
|
||||
$ ./install.sh
|
||||
```
|
||||
|
||||
<h1> leandvb rtlsdr receiver installation </h1>
|
||||
`./install.sh`
|
||||
This install leandvb : a simple dvb-s receiver with rtl-sdr usb dongle
|
||||
([leandvb dvb-s receiver](http://www.pabr.org/radio/leandvb/leandvb.en.html))
|
||||
You can run the receiver : `./scripts/leandvb2video.sh`
|
||||
|
||||
<h1>Hardware</h1>
|
||||
# Hardware
|
||||
Plug a wire on GPIO 12, means Pin 32 of the GPIO header ([header P1](http://elinux.org/RPi_Low-level_peripherals#General_Purpose_Input.2FOutput_.28GPIO.29)): this act as the antenna. Length depend on transmit frequency, but with few centimeters it works for local testing.

|
||||
Example : sudo ./rpidatv -i sample.ts -s 250 -c 1/2 -o RF -f 437.5 -l
|
||||
```
|
||||
Example : `sudo ./rpidatv -i sample.ts -s 250 -c 1/2 -m RF -f 437.5 -l`
|
||||
# Transport stream
|
||||
**rpidatv** needs a DVB transport stream in input. In the past, ffmpeg was used to generate transport stream. Because ffmpeg is not completely DVB compliant and induces latency, an other tool is proposed : **avc2ts**
|
||||
|
||||
<h2> Minimal graphical menu </h2>
|
||||
You can launch a graphical menu located in /scripts folder
|
||||
`./frmenu.sh` for french language
|
||||
`./gbmenu.sh` for english language
|
||||
# H264 encoder and transport stream encapsulator
|
||||
**avc2ts** is located in rpidatv/bin folder
|
||||
```
|
||||
avc2ts -1.0.0
|
||||
Usage:
|
||||
rpi-avc2ts -o OutputFile -b BitrateVideo -m BitrateMux -x VideoWidth -y VideoHeight -f Framerate -n MulticastGroup [-d PTS/PCR][-v][-h]
|
||||
-o path to Transport File Output
|
||||
-b VideoBitrate in bit/s
|
||||
-m Multiplex Bitrate (should be around 1.4 VideoBitrate)
|
||||
-x VideoWidth (should be 16 pixel aligned)
|
||||
-y VideoHeight (should be 16 pixel aligned)
|
||||
-f Framerate (25 for example)
|
||||
-n Multicast group (optionnal) example 230.0.0.1:10000
|
||||
-d Delay PTS/PCR in ms
|
||||
-v Enable Motion vectors
|
||||
-i IDR Period
|
||||
-t TypeInput {0=Picamera,1=InternalPatern,2=USB Camera,3=Rpi Display,4=VNC}
|
||||
-e Extra Arg:
|
||||
- For usb camera name of device (/dev/video0)
|
||||
- For VNC : IP address of VNC Server. Password must be datv
|
||||
-p Set the PidStart: Set PMT=PIDStart,Pidvideo=PidStart+1,PidAudio=PidStart+2
|
||||
-s Set Servicename : Typically CALL
|
||||
-h help (print this help).
|
||||
Example : ./rpi-avc2ts -o result.ts -b 1000000 -m 1400000 -x 640 -y 480 -f 25 -n 230.0.0.1:1000
