Problem with live streaming

[jahanzeb07]

Hi, first thank you for such a nice program. Currently I'm using it to record videos with sound and its working fantastic. I am newbie in raspberry pi and couldn't figure out how to stream the video using your program. I followed the instructions in ReamMe file but may be I am not getting some thing. To stream video first I did $ ./picam -o /run/shm/hls and then I put the IP address of my Pi into another PC in the same network like http://RPIip/run/shm/hls/index.m3u8. I did same in my PI browser but it didn't work and I think I am not doing right. You explained it quit well but I need step by step instructions. Thank you for the help.

@jahanzeb07 To enable HLS (HTTP Live Streaming), you also have to serve /run/shm/hls/ directory with an HTTP server such as nginx or Apache. Then, you can view the stream at http://RPIip/index.m3u8.

Thank you for your reply. Can you refer me any document or HowTo which I can follow to serve my directory to the server. Thank you and happy new year!

@jahanzeb07 See this page for instructions. You don't need to do the section "ADDITIONAL - INSTALL PHP".

Hi, thank you for your assistance. I followed the instructions from the page you referred and successfully installed the nginx server and checked it after starting and it was working. Then, I followed the nginx documentation and I added following block into nginx.conf file: server { location /hls/ { index index.html index.m3u8; root /run/shm/hls; } }

but still it is not working and I got error "404 Not Found". I don't know what I am doing wrong. I did google for the problem but couldn't find solution. Thank you for your time and support.

UPDATE: I added this block of code under http section like this: server { location /hls/ { index index.m3u8 index.html; root /run/shm/hls; } then restart the nginx service which is successful and then $ ./picam -o /run/shm/hls. I tried to access the index.m3u8 like: http://localhost/index.m3u8 and http://localhost/run/shm/hls/index.m3u8 but in both cases, 404 not found.

@jahanzeb07 Replace root /run/shm/hls with root /run/shm like this:

        location /hls/ {
                root /run/shm;
                index index.m3u8 index.html;
        }

Then, you can access the HLS stream at http://localhost/hls/index.m3u8 or just http://localhost/hls/.

Hi, thank you again. I tried with your code but still no success. I got the same error, 404 not found. I am posting here everything so you may figure out what I am doing wrong. In /etc/nginx/nginx.conf file within http section I added: server { location /hls/ { root /run/shm; index index.html index.m3u8 index.htm; } } I restart the nginx server by

sudo service nginx restart and sudo nginx -s reload

then,

In picam directory I did,

./picam -o /run/shm/hls

output of the command is

pi@raspberrypi:~/picam $ ./picam -o /run/shm/hls/ configuring devices error: cannot open audio capture device 'hw:0,0': No such file or directory hint: specify correct ALSA device with '--alsadev <dev>' warning: audio capturing is disabled capturing started

Thank you for your patience and guidance.

@jahanzeb07 Can you show me the full contents of your /etc/nginx/nginx.conf and /etc/nginx/sites-available/default?

[jahanzeb07]

Hi, thank you very much for the update in ReadMe file. I just saw your update and I got now what I was doing wrong. I was adding location in /etc/ngnix/ngnix.confonly but not in /etc/nginx/sites-available/default . I added the code in default file also and now it is working. I can watch the stream from my Pi using VLC Player. Is it possible to watch the live stream from web browser?

Thank you again for your time.

@jahanzeb07 Great! You can use https://github.com/dailymotion/hls.js to play HLS in a browser.

Using apache I just had to do this:

cd /var/www/html/ mkdir hls ln -s /run/shm/hls hls
