VLC streaming & HTML5 & "smart" TVs

kapetr · Postby **kapetr** » 25 Apr 2015 10:37

Hello.

My "smart" tv has neither option to receive streams (udp, rtp) directly nor open multimedia files (http) directly.
If I try open a file link in TV browser (Opera) e.g. http://www.noiseaddicts.com/samples/2555.mp3 then I just get error info: "Downloading not supported".
I do not want that TV should download (save) the file I want that TV should play the file.

But if I embed it in HTML5 element, then TV plays it

Code: Select all

<!DOCTYPE html>
<html>
<body>
<audio controls>
  <source src="http://www.noiseaddicts.com/samples/2555.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
</body>

The Idea is - use as <source> VLC http stream. But don't know how to do this.
Stream:

Code: Select all

[code]cvlc -v file:///media/koko.mp3 --sout '#std{access=http,mux=ts,dst=:8080/audio}

[/code]
Normal receive OK: "vlc http://192.168.1.15:8080/audio"

But if I use: "http://192.168.1.15:8080/audio" as <source>

then TV (computer too) do not play it.
I thing the problem is in container / MIME type.

- VLC streams out TS stream including MP3 audio, but
- browser (TV or comp) expect MP3 file (I do not know if we can talk by xxx.mp3 file about container at all ?!)

How can I configure http stream to be as sending e.g as MP3 audio file ?

Thanks.

?? I do not want to public files with web server. Using file:// as VLC source was just example of course.
Target is to stream e.g. screen:// or dvb:// VLC sources to TV/web browser.

PARTIALLY SOLVED:

AUDIO:

HTML5 supports only MP3 , Wav and Ogg - see http://www.w3schools.com/html/html5_audio.asp
To avoid container enclosing and to set audio/mpeg in http response from VLC:

Code: Select all

cvlc -v file:///tmp/test.mp3 --sout '#std{access=http,mux=raw,dst=:8080/audio}' --sout-http-mime "audio/mpeg"

and in web page:

Code: Select all

<audio controls>
  <source src="http://192.168.1.15:8080/audio" type="audio/mpeg">
Your browser does not support the audio element.
</audio>

-> it plays audio in computer and TV browsers

Note: by TV it takes long time to catch the audio (probably due missing header of MP3 ?)

VIDEO:

HTML5 supports only MP4, WebM and Ogg - see http://www.w3schools.com/html/html5_video.asp
Only OGG is streamable by VLC - see http://www.videolan.org/streaming-features.html

Code: Select all

cvlc -v file:///mnt/DATA/VIDEO/HP-Drak.mkv --sout '#transcode{vcodec=theo,vb=1024,scale=1,acodec=vorb,b=128,channels=2,samplerate=48000}:std{access=http,mux=ogg,dst=:8080/video}' --sout-http-mime "video/ogg"

and in web page:

Code: Select all

<video controls>
  <source src="http://192.168.1.15:8080/video" type="video/ogg">
Your browser does not support the audio element.
</video>

But by video there is problem unfortunately:

-- computer browser plays the video, but the quality is absolutely TERRIBLE - like 160x120 video at 50 kb/s.
I had test encoding theora video with avconv too and it is much better (but low quality anyway). I do not know, where is problem with this modern codec. It is worser then low-res mjpeg!

-- TV browser do not play itl. It do not even try to access it (the http://192.168.1.15:8080/video) - not sure why - maybe it is not able to play "video/ogg" => it do not try it at all. But MP4 (which TV as mediaplayer plays) is not streamable by VLC

Maybe could someone try it on his Smart TV ? [I have Gogen == +-noname TV]
