I've mounted a transcoding server with a simple web control interface to help viewing your videos in a compatible web browser.
It includes ffmpeg own compilation ready to do real time transcode in rpi 3 and rpi 4 using omx and mmal.
It also works great spawned by tvheadend
Also includes nginx specific compile to help the transcoding process.
You can even add nginx additional configurations.
add-on will be identified as service.ffmpeg in kodi.
FFmpeg TRANSCODING Server for Raspberry Pi
This add-on includes:
1 ffmpeg with omx and mmal support for Pi, and also libx264 with presets (for fast transcoding).
can be used in a tvheadend profile (see bellow).
2 nginx with rtmp and hls for transcoding services.
nginx can also publish your custom sites.
3 A small transcoding web based service - you can transcode your local stored movies across the network.
even when on low bandwidth.
Compatible with vlc player and chrome (must install a m3u8 extension for playing streams).
= QUICK SETUP
After install go to add-on settings in kodi:
- Change user and pass (defaults to user / pass)
Access to the User interface with a web-browser:
in which path_to_transcode is the directory path that contains video contents to be browsed and transcoded.
use linux format (example: /media/hdd/movies)
= TECH STUFF
ffmpeg is used as the encoding for the server,
but it is also usable trought command-line.
just call as:
If you use tvheadend, you may define a profile that pipes video streams trough ffmpeg before delivering.
The following example uses x264 to live transocde with a Rapsberry Pi4.
Assuming ffmpeg server kodi add-on installed in LibreELEC:
- tvheadend / configuration / stream / stream profiles / add
- create and enable new stream profiles with the followig:
. enabled = true
. Data timeout = 0
. Restart on error = true
. Continue if descrambling fails = true
. Descrambling timeout = 10000
. Command Line
/storage/.kodi/addons/service.ffmpeg/bin/ffmpeg -loglevel quiet -i pipe:0 -vcodec libx264 -preset faster -s 640x480 -vb 512k -bufsize 1024k -g 100 -af "aresample=async=1:first_pts=0" -acodec aac -ab 128k -f mpegts pipe:1
. Kill signal = SIGTERM
. Kill timeout = 15
- The ffmpeg provided command will do live transcode with the major setup:
. video codec : libx264
. preset : faster
. frame size : 640x480
. video bitrate : 512k
. audio codec : aac
. audio bitrate : 128k
. audio sync with video (to handle received lost frames)
2 NGINX - ADDITIONAL SITES:
As nginx is being used, you can define additional servers in:
Or by samba as:
3 TRANSCODING SERVER
- TRANSCODING CONTROL PORT : Defaults to 9996.
Simple CTRL GUI : http://ip:port/cgi-bin/movies.cgi
Start Transcode : http://ip:port/cgi-bin/transcode.cgi
Stop Transcode : http://ip:port/cgi-bin/stop-transcode.cgi
Play stream : http://ip:port/hls/movie.m3u8
Movies will default transcode to 640x480 @ 512kbps.
Publishing is made to rtmp://localhost/hls/movie (internal port 1935)
- USER AND PASSWORD:
User and password defaults to "user" and "pass".
Should be changed in kodi's add-on configuration screen.
- KODI ADD-ON CONFIGURATION:
In the add-on configuration screen, you can define:
- Server port (defaults to 9996);
- Transcoded streaming video frame size (defaults to 640 x 480);
- Transcoded streaming video bitrate (defaults to 512 Kbps);
- User and password to access the control site;
- Control GUI:
Should be called with the local server directory with movies to transcode.
This interface allows choosing the movie, start transcoding, start playback and stop transcoding.
m3u8 can be watched in chrome by installing an extension. VLC Plays them directly.
transcode.cgi can be called directly by giving the movie FULL PATH NAME WITHIN THE SERVER,
and several optional arguments.
The example bellow uses the default options:
All arguments are self explanatory, except "caller",
which is an optional address to transfer execution after the transcoding is started.
If "caller" is not passed as argument,
transcode.cgi will stay in browser with a small simple interface to playback and stop the stream.
