Send stream from home to AWS EC2 instance

Postby Israel Calvete » Mon Aug 13, 2018 12:23 am

Hi,

I'm trying something odd to get fun. Send stream from home to AWS EC2 instance.

First aproach. Read stream with ffmpeg
(tested locally successfully)

hdhomerun_config discover sya my device have ip 192.168.1.200 so I open port on my router in this way

<my home public ip>:5005 -> 192.168.1.200:80
<my home public ip>:5004 -> 192.168.1.200:5004

w3m and telnet say everything is ok.

But...

from EC2 instance I do

Code: Select all

/usr/bin/ffmpeg -y -i 'http://<my home public ip>:5004/auto/v5057?transcode=internet240' -t 12 -vn -acodec pcm_s16le -ar 16000 -ac 1 '/tmp/test.wav'
In tuner1 I can see...

Code: Select all

Virtual Channel none Frequency 698.000 MHz Program Number 186 Modulation Lock t8qam64 Signal Strength 89% Signal Quality 100% Symbol Quality 100% Streaming Rate none Resource Lock <EC2 public ip>
In system logs...

Code: Select all

19700102-10:27:25 Tuner: tuner0 tuning 5057 Telecinco (t8qam64:698MHz-186) 19700102-10:27:25 Tuner: tuner0 streaming http to <EC2 public ip>:34124
Everything seems ok but ffmpeg don't get any data.

Seccond aproach. Send stream to wowza

I have a wowza server running in EC2 instance


From a linux box at my home

Code: Select all

root# /usr/bin/hdhomerun_config 1250D7B2 scan /tuner1 scan.log root# /usr/bin/hdhomerun_config 1250D7B2 set /tuner1/channel auto:651000000 root# /usr/bin/hdhomerun_config 1250D7B2 get /tuner1/streaminfo root# /usr/bin/hdhomerun_config 1250D7B2 get /tuner1/program 190 root# /usr/bin/hdhomerun_config 1250D7B2 set /tuner1/target rtp://<wowza server public ip>:1935/TEST/hdhr root# echo $? root# 0
Ends without error buy doesn't work
This was a long shot but ....

Any ideas to do this.

Thanks !!!

HDHomeRun devices have a TTL of 3 set on outgoing video packets, as specified by DLNA standards. You will not be able to stream over the internet.

I have had pretty good luck using apache as a reverse proxy, to stream my extend over the internet. If you have a working apache installation on the same network as the hdhomerun, enable mod_proxy:

Code: Select all

sudo a2enmod proxy sudo a2enmod proxy_http
and use this directive:

Code: Select all

ProxyPass /hdhr/auto/ http://hdhomerunlocalIP:5004/auto/ ProxyPassReverse /hdhr/auto/ http://hdhomerunlocalIP:5004/auto/ ProxyPreserveHost On

Now, remotely I can goto http://myprivatedomain.com/hdhr/auto/v14.1 in VLC, and it will begin playing.

I finally achieved it.

I used ffserver.

ffserver with 4 feeds and 4 streams.

4 ffmpegs consuming hdhomerum and feeding ffserver. Besides, I used ffmpeg to trascode the streams acording to my needs.

Bad new? I need a machine to do that.

Thanks all.

Radio example:

ffserver.conf

Code: Select all

<Feed feed0.ffm> File /tmp/feed0.ffm FileMaxSize 200K ACL allow 127.0.0.1 </Feed> <Stream s0.wav> Feed feed0.ffm Metadata title "Stream 0 wav" Format wav AudioCodec pcm_s16le AudioBitRate 32 AudioChannels 1 AudioSampleRate 16000 NoVideo </Stream>
Incoming feed with ffmpeg

Code: Select all

/usr/bin/ffmpeg -i "http://192.168.1.200:5004/auto/v5054?transcode=internet240" -vn -ar 16000 -ac 1 http://localhost:8090/feed1.ffm

Final url is http://192.168.1.123:8090/s0.wav. (With public IP from Internet)
