VideoLan streaming via HTTP

Postby HttpVlc » 06 Jun 2007 09:03

[i]Hi,

I am using the VideoLan to stream an AVI file thru http.
I have the following queries:
1.If we stream an AVI file,how does it stream the data?is it in AVI format itself?
2.On the server side when we run the wizard to stream to network,the last dialog box asks for encapsulation method,wherein it displays the following options:

MPEG-TS,MPEG-PS,MPEG-1,OGG,ASF,RAW.
while MP4,MOV are disabled.

which format to select and wat does this encapsulation signify.


Regards,
TEL

well, they can be better explained if you read the faq and the wiki.

On Linux, blindly use VLC, SMPlayer, Kaffeine, GXine, Totem and MPlayer

It's all in the docs but as a beginner (some weeks ago) I could have used some extra help too! So here are the fundamentals:
1.If we stream an AVI file,how does it stream the data?is it in AVI format itself?
AVI is a standard for encapsulation of the video & audio data i.e. putting them together into a single data stream. The audio and video themselves are encoded in formats such as MPEG, DivX, MP3,...

In theory, any encapsulation format can hold any encoding. In practice, only some combinations are used.
For streaming in http, the encapsulation of choice is MPEG-TS.

=> If you stream AVI via http using MPEG-TS:
- The encapsulation format is changed from AVI to MPEG-TS
- The encodings of audio and video stay the same.

Hope this will get you going. Success!

Paul
