muxing 2 es into 1 ts

[didi156]

This question may seem trivial, but searching the docs and the forum I couldn't find any enlighting information.
I want to mux a H.264 ES and a AC-3 ES into a TS.
Using the GUI (File->Streaming Assistant->Transcode...) I couldn't find a way to do this. Is there another place to do this? I'm not familiar with VLC yet.
Also, the cmd-line syntax is

Code: Select all

vlc input_stream --sout "#module1{option1=parameter1{parameter-option1},option2=parameter2}:#module2{option1=...,option2=...}:..."

since here only 1 "inpute_stream"-parameter is allowed, I also don't see how to do this here. I guess there may be a module which can do that, but I didn't find one...

you need to do that with the bridge-out and bridge-in sout elements using the vlm interface. Have a look at the Mosaic howto on the wiki for more info : http://wiki.videolan.org/index.php/Mosaic

That doesn't look as simple as I hoped (at a first look). Maybe I'll try this out, thanks.

an example vlm config would be :

Code: Select all

# this sends the 1st es to the bridge system new es1 broadcast enabled input <your input> output #bridge-out # this grabs the 1st es and groups it with the 2nd es. # you can change display to any normal sout element. # see streaming howto chapter 3 new es2 broadcast enabled input <your other input> output #bridge-in:display

(this hasn't been tested so their might still be some things to tweak)

I tried this out now.

Code: Select all

new es1 broadcast enabled input "/server/nfs/testfiles/SD-sample-video.264" output #bridge-out new es2 broadcast enabled input "/server/nfs/testfiles/SD-sample-audio.mp3" output '#bridge-in:display control es1 play control es2 play

I tried to add the "control play" commands seen in the howto, but doesn't do nothing.
I saved the config file in the directory where I launched vlc with:

Code: Select all

vlc -vvv --vlm-conf config.vlm

I don't get any console output indicating that something is to be done (only interface related debug).

I also tried with output module standard{mux=ts,url=mux.ts,access=file}.

Is the way I tried correct or did I miss something?

I also tried this config:

Code: Select all

new my_mux broadcast enabled setup my_mix input input "SD-sample-video.264" input "SD-sample-audio.mp3" setup my_mux output '#standard{mux=ts,access=file,url=mux.ts}' control my_mux play

seen in chapter 5. I guess this way the 2 streams are muxed without sync info (timestamps or whatever...), Is that correct?

Salut a Paris et merci beaucoup [/code]

to load vlm stuff you need to use the telnet or http interface. Just add "-I telnet" to your vlc command line.

bonne chance,

[didi156]

Well, that was a good hint

Now I get a lot more output of vlc. Again the vlm config I uesd:

Code: Select all

new es1 broadcast enabled input "/server/nfs/testfiles/encoding/ts/SD-sample-video.264" output #bridge-out new es2 broadcast enabled input "/server/nfs/testfiles/encoding/ts/SD-sample-audio.mp3" output '#bridge-in:standard{access=file,url=mux-es.out,mux=ts}'

after doing

Code: Select all

control es1 play control es2 play

in telnet terminal, I get all that debug output attached. I don't understand if I still miss something in the vlm script or if it simply can't handle H.264 muxing:

try removing the quotes arrond '#bridge-in ....'

[didi156]

yeah, that was it, thanks.
Now in the resulting mux the video stream plays to fast, but that's another issue...
