[gentoo-user] How to use mplayer play file online?

[Chuanwen Wu]

Hi,
I want to use mplayer to play files on the ftp server. For example, I
have some files on: ftp://user:passwd@myftpserv/thefile. Now I want to
play it, but I won't need to download all the file first then play it.
Is there any advice?

Thanks in advanced!

You have to download it as it has to be in RAM before mplayer can use 
it.

And you have to download the whole thing as it's a container file, not a 
stream.

So, you mean mplayer can NOT play stream?
As far as I know, mplayer can play file on a web(html) site.
In "man mplayer", I can see that :

       Stream from HTTP:
       mplayer http://mplayer.hq/example.avi

       Stream using RTSP:
       mplayer rtsp://server.example.com/streamName

So, I think there may be some ways to play mplayer from the ftp(or
other protocol).
Somebody work it out and suggested me to do it like this:

wget ftp://THE_FTPSERVER/1.RM -O - | mplayer -cache 8192 -

But I just failed every time I tried to do it in this way. Can you do
it successfully?

mplayer can play streams. But the4 thing you are trying to play is not a 
stream, it is a file.

You cannot change the nature of the thing on the ftp server as it is 
whatever it is. To turn it into a stream, you will have to log into the 
ftp server and do whatever is necessary there to do that. mplayer is 
not able to make such changes for very obvious reasons.

Meanwhile, just download the file and play it. What's the problem with 
that? To view the whole thing from beginning to end all that data would 
still have to move from the server to your local machine anyway.

But I can save the time of downing the file and when I want to watch
any movie, I don't need to wait.

Does the wget itself work, eg. does wget ftp://ftpserver/file.ext 
download your file? If not, you may need to add some quoting... For 
instance, the [ character should be quoted twice, once for the local 
shell and once for the remote server (at least that was the case on a 
quick test I did), so downloading a file called "[.ext" would become

wget 'ftp://ftpserver/\[.ext'

or

wget 'ftp://ftpserver/\[.ext' -O - | mplayer -cache 8192 -

Michael

Tough. You can't do what you want to do from the client.

I'm not sure if mplayer supports authentication, but you could try to
"pipe" the output from another client. Something like:

curl --auth-options ftp:/exemple.com/patth/file | mplayer -

or

wget --auth-options ftp://exemple.com/patth/file -O - | mplayer -

You can start the download and start mplayer on the (incompletely) 
downloaded file.

Yes, I can see the file after downloading, but mplayer just don't  play it.
I attach the output below, when I do "wget ftp://THE_FTPSERVER/1.RM -O
- | mplayer -cache 8192 -" below. There are some Chinese characters. I
am sorry because I don't know how to get English output(although I
have tried to set the locale to POSIX), but I will give the translated
one:

GNUMP3d is available as a Gentoo package:

    http://www.gnump3d.org/

You run it on your server.  In its config file, you point
to a directory with mp3 or ogg files.  It will do the magic
work of converting files to streams, so you can choose and
play music from another box on your network.

Hope this helps,
Ed

I do this all the time over NFS with Matroska-files that are still being
created by my server. If you can't navigate within the movie, add -idx
or --force-idx to create a new index on the fly.

I have found a way. Just add USE=ftp when emerge mplayer.
Then, we can play movie in ftp use mplayer:

 mplayer ftp://FTP_SERVER/FILE

But I still want to find a "pipe" way like what you show above.
I have a simple program, which can fetch a file in a remote
machine(this machine also run my protocol).
If mplayer can play in a pipe way, then I can player media like this:
MY_PROGRAM --fetch --MY_SERVER -O - | mplayer -
