Been searching for hours and only need confirmation

[ebknoppert]

Main goal is to download the http stream like mp3 or aac straight to disk without quality loss.
When used on mp4 for example i would like the file to be ok with any player and thus a need for a container.

I have it working like
--intf wx %URL% :sout=#duplicate{dst=display,dst=std{access=file,mux=mp4,dst=%FILEOUT%.mp4}}

and (mp3 example)
%URL% :demux=dump :demuxdump-file=c:\cdrom\output.mp3

This first one suits me the best, it seems to dump the bytes downloaded into a new container but does not seem to modify the data like re compressing it or whatever.
The 2nd seems to be doing the same but it allows you to skip the container (dummy or whatever) which don't care for per se, at least this mode is described as saving to disk without modification.

Can someone please tell me that the first is as good as the 2nd, the 2nd does not let me listen to the audio simultaniously.
The duplicate mode documentation does not elaborate on the quality, while it may be obvious since i did not use the transcode statement here.

Thats all fokes..
Edwin,

Yes. this is good too, and will not change the coding quality.

[ebknoppert]

Thanks, that was important to me

[Jean-Baptiste Kempf]

cool.

I always used vlc086 and i am now trying to use vlc 2.1.3. since it supports mp4 recording.

I have this url:
http://www.radioveronica.nl/player/radioveronica.pls

it delivers 64kb aac mp4a but i want to automate it.

--intf wx http://www.radioveronica.nl/player/radioveronica.pls :sout=#duplicate{dst=display,dst=std{access=file,mux=raw,dst=filename1.mp4}}

Problems:
1) But it does not longer show the userinterface and thus hard to abort.

2) The result seems incorrect, no player can open and play the file when done.

Been visitting https://wiki.videolan.org/VLC_command-line_help but vlc is daunting to me..

Just want to use the Windows taskplanner to run (and stop) and download the stream *without* re-encoding to disk.
Mp3 via vlc086 works fine.

Thanks

Hi
The radioveronica.nl stream is aac, so "mux=raw" is no good this time.
Use "mux=mp4".
{access=file,mux=mp4,dst=filename1.m4a}

This command makes a 30 second test recording (Windows XP).

Code: Select all

"C:\Program Files\VideoLAN\VLC\vlc" -vv --stop-time=30 -I dummy http://8633.live.streamtheworld.com/VERONICAAAC_SC --sout="#std{access=file,mux=mp4,dst=test.m4a}" vlc://quit

[ebknoppert]

Bit dumb of me since my first post here already had 'mp4' for tag

But i have tried better but in fact same results..
The output file is not correct + the UI is not shown, here is my full (Windows .lnk) shortcut:

"C:\Program Files\VideoLAN\VLC213\vlc.exe" --intf wx http://www.radioveronica.nl/player/radioveronica.pls :sout=#duplicate{dst=display,dst=std{access=file,mux=mp4,dst=d:\cdrom\filename1.mp4}}

The i tried the dump again, but i dumps the pls contents and thus not follow up the urls..
"C:\Program Files\VideoLAN\VLC213\vlc.exe" http://www.radioveronica.nl/player/radioveronica.pls :demux=dump :demuxdump-file=d:\cdrom\filename2.mp4

One of the follow up urls is:
"C:\Program Files\VideoLAN\VLC213\vlc.exe" http://8623.live.streamtheworld.com:3690/VERONICAAAC_SC :demux=dump :demuxdump-file=d:\cdrom\filename2.mp4

This actually saves the stream 100% ok and is playable afterwards + also shows the UI but without sound.
I can write me an app to obain an url from the pls but maybe there is a switch for that when using the dump method?
Also enabling the sound would be nicer so i can verify it sometimes, it's not a major issue but would be nice.

[ebknoppert]

We had a cross-post (edit), i'll try your option as well but maybe you can see my post as well.

[ebknoppert]

Your line records (without sound during record) but each 30 secs it erases the file and records again.

[bat999]

... but each 30 secs it erases the file and records again.

Works for me, but I am not in Holland.
Try with a different feed for radioveronica.nl instead of http://8633.live.streamtheworld.com/VERONICAAAC_SC.

I moved towards the dump method, gives me a better feeling about the dump being 1:1
+ the UI is visible.
Any chance on enabling the sound to the speaker as well?

I have this wrapper app for running vlc, adding the max record time may be handy as well.
Will try that myself now.

[bat999]

... the dump method...

It's your choice...
but run 2 tests:-

Code: Select all

--sout="#std{access=file,mux=mp4,dst=test1.m4a}"

and

Code: Select all

:demux=dump :demuxdump-file=test2.m4a

Use MediaInfo program to compare test1.m4a and test2.m4a results.
See the difference?

test1.m4a plays OK on my iPod
But it ignores test2.m4a.

[ebknoppert]

I am aware that the 'container' maybe different but i am using the record button the next day to get a 1:1 mp4.
This maybe a better mp4 for your ipod
This due to lack of a good audio trimmer/fader (without re-encoding).
