How to save (not download) a streaming video to disk?
Uwe
Firefox add-on FlashGot and it works. But on some sites FlashGot can't
find an URL which (as far as I know) it needs to download a video. So
these sites only stream the flash video (which I can watch real-time
in my browser) and download is no option, right?
Can I redirect this video stream and save it in a video file without
any loss of quality?
I googled this a lot and did many tests.
I found out that vlc has streaming capabilities. But vlc also needs an
URL to work.
What about ffmpeg? The man page reads it "can grab video and audio
from devices". I tested "ffmpeg -f alsa -i /dev/dsp -f video4linux2 -
i /dev/video ..." but first there are no video or audio devices in /
dev and even when I create them with mknod ffmpeg doesn't recognize
them. So I used "hw:0,0" instead of "/dev/dsp" and ffmpeg recognizes
the device but no sound is recorded. I found "hw:0,0" on the internet
and it's exactly the value I have to set in the audio settings of vlc.
Does vlc gets this value from /proc/asound/pcm?
"ffmpeg -f x11grab -i :0.0 ..." which captures the X display works but
yields a low quality video file.
In case I could save the stream with ffmpeg what input file names
(video and audio device names) do I have to use behind the -i option?
Do you have any other idea to solve my problem?
For internet use I have a Sidux 2010-01 Live CD which is based on
Debian unstable.

reencoding the sampled data into a video format. Both is CPU/bus-hungry,
which causes framedrops. I think that is what you mean "low quality video
file".
As accessing video memory is slower than to the main RAM, you could use Xvnc
to render the video into main RAM. Close the vnc client during the sampling
so no unneccesary transfer to video memory is taken. Second, use a video
codec that does not take too much CPU. MJPEG comes to mind, as it does no
inter-frame processing. If that's not fast enough, output to raw video.
Instead of MP3 for audio use WAV.
If that's not enough, you'll need a much faster computer to sample the
quality you want.

Have you tried the plug-in "Download Helper" ?
I have yet to find a stream it can't save. Since you didn't include an
example, I can't test it for you.

Good idea to give an example :-)
I'd like to download a few videos from http://www.prosieben.de/ for
example:
http://www.prosieben.de/tv/tv-total/video/ganze-folge/30447-tv-total-show-1501-vom-02092010-1.1994016/
When watching the bar below the frame where the video is shown it
looks like the stream consists of different single videos: The main
video (which I want to save) and some commercials in between. The
problem with FlashGot and with DownloadHelper (which I've tested now)
is that the main video isn't listed for downloading.

The problem with grabbing the X window is that even if I manage to
exactly capture the window there would be a loss in quality. I know
this because when I play the same mpg file in vlc on my computer (or
watch the original flv video in a browser) and with a DVD player over
a TV set the quality in vlc is less. So already the X window display
is less in quality compared to the data in the mpg file. But perhaps
that's the best solution I have.
So how do I render the video into RAM with vnc? I have 2 GB RAM so
hopefully a 45 min video would fit into it because I don't know how
much space is left.
I already used mpg format in my tests but perhaps saving just a raw
video would help. I could convert it afterwards into a mpg file with
ffmpeg.
But apart from that: Even if the website prevents me from downloading
the video the data for displaying the video reach my computer and my
browser can display it with the flashplugin. So isn't there a Firefox
add-on that just takes those data and outputs a video file? Or any
other program that can process the stream in the desired way?

When I capture the X window with ffmpeg the output file has no audio.
Ok the X window has no sound so perhaps that's how it works.
I googled again and found:
http://ishmilok.blogspot.com/2010/07/webcam-recording-using-vlc-on-linux.html
A description for capturing the audio and video devices with vlc.
Looks like exactly what I need.
Media -> Convert/Save -> Capture Device -> Device Selection:
There's no /dev/video0 in my /dev directory so I did "mknod /dev/
video0 c 81 0". My audio device is "hw:0,0" according to the Audio
Settings of vlc so I use this as Audio Device Name.
But I get this error message:
Your input can't be opened:
VLC is unable to open the MRL 'v4l2:///dev/video0'. Check the log for
details.
Can't find any logfile. When I start vlc with the --file-logging
option I get this:
-- logger module started --
-- logger module stopped --
"ls -la /dev/video0" yields:
crw-r--r-- 1 root root 81, 0 Sep 5 15:16 /dev/video0
But "v4l2-ctl --list-devices" yields the error message:
Failed to open /dev/video0: No such device or address
I changed the group of /dev/video0 with "chgrp video /dev/
video0" ($USER is a member of the group video) in case this is
important but I get the same error messages.
So I don't know what to do (even after lots of googling). Any ideas?

No, it is not what you need, it is for capturing video from a webcam.
Try to recover the video from the browser cache ~/.firefox/[something]/Cache
If it isn't there try capturing it with a local proxy or a network sniffer.

Also take a look for /tmp/Flash* files.
Here's a script I use to find videos that flash downloads while
viewing (you need to be in the directory that contains the FF Cache
directory to use it). It looks uses file & looks for various types of
videos.

The video isn't available, right now.
Tried it with another, same message.

No, it's not. This discusses a/v capture from a webcam (a device),
not a stream.

There is no /dev/video0 on your system because there is no webcam
attached. Adding the device node is pointless because there's no device
(webcam) attached to it.
You need the stream url in order to capture a video stream directly. If
you have it, then something like flvstreamer or rtmpdump /may/ help you
(but this is pretty low level stuff).

You couldn't watch the video if you didn't have the URL. And if you
can see/hear a file on your computer it is already downloaded to
RAM. What is meant by "downloading" is simply to copy it to a
permanent storage medium like a hard disk.
You don't "go to a website", you connect to another computer
and download files from it.

Using Flash with Firefox on Linux, I seem to get 2 copies of each
video actually downloaded: 1 is in FF's Cache directory, and the other
is in /tmp as /tmp/Flash*. The copy in /tmp normally disappears when I
start viewing another flash video, but the one in Cache tends to stick
around for awhile, probably dependent on the disk cache limit I've set
in FF.

Even that's misleading. There isn't any "up" or "down" involved.
Files are simply transferred from one computer to another. TCP

Hey Jerry,
Looks like the copy that's actually viewed is in /tmp. If you want
to see it again, there's a copy in your cache that would be copied
to /tmp for, as you say above, as long as you've set the cache limit.
If you really want to save it, then copy it to a dir in ~.
And don't waste any time doing it :-)

Meanwhile I found out that this web cam tutorial is NOT what I need. I
somehow thought the author records some web cam output over the
internet and not his OWN one. Anyway.

I also came across rtmpdump and tried to find the option parameters I
need with wireshark with no success. I exported the captured data in a
text file and searched for the regular expression "rtmp[[:alpha:]]
\{0,2\}:\/\/" to find all rtmp, rtmpe, etc. followed by "://" but
there's nothing.
Could rtmpsuck help? I found it with rtmpdump but there's no man page.
And I will check out flvstreamer.

The problem is it's not ME that has the URL but my BROWSER/
FLASHPLUGIN. That's the reason why I don't understand there's no
browser plugin who is capable of downloading what I can see in my
browser window.
Jerry Peters wrote:

Before I watched the video I waited a few minutes and then just took a
look at the time stamps of the directories (and files) but I couldn't
find anything in /tmp. But in $HOME/.mozilla/firefox/[something]/Cache
a couple of files were updated and I saved them. I opened the biggest
file with vlc but again it's just a commercial and NOT the main video!
There's another thing I haven't tested yet: I read about a -dumpstream
option of the mplayer for downloading streamed videos.
I welcome any further suggestions or ideas.

If they have it then it is probably in the HTML source in
a java script. Your browser will show you the source and
you can search it for the filename.

Neither do I. Are you sure it isn't? Have you consulted the
help files/docs?
(Would wget work for this?)
Like I already said: If you can see the file it _is_ already
downloaded (or at least what you have seen and are seeing
has been downloaded). You couldn't see it otherwise. What
you need to do is re-direct it to a storage medium, I guess.
For that you'll need a commmandline/console tool. A viewer.
$ commandline_tool args URL > /tmp/foo.swf # (I think .swf is right)
or
$ commandline_tool args URL | tee /tmp/foo.swf

Not in my experience. There are many (~70) Mozilla addons that deal with
such things according to
https://addons.mozilla.org/en-US/firefox/search/?q=flash%20download but I
find https://addons.mozilla.org/en-US/firefox/user/5051851/ to be the
most versatile and user-friendly of any of them that I tried.

In wireshark I forgot to "enable network name resolution", so I did
again capture the data when the video started.

I searched the HTML source code and the capture file of wireshark for
"rtmp", "\.flv", "\.swf" and "\.mp4" but I couldn't find the main
video only commercials. And I searched for "rtmp[^[:space:]]*flv",
"rtmp[^[:space:]]*swf" and "rtmp[^[:space:]]*mp4" and there're no
matches at all. I'm going to search for keywords related to the video
content and hopefully I get the parameters for rtmpdump.

As far as I understand it the only thing that's really needed is that
the video stream data goes through the part of the RAM that's used by
firefox, and is stored there temporarily. Before and after playing a
particular part of the video no storage is necessary at all, neither
in RAM nor on disk. I'm afraid that's the reason I couldn't find any
relevant temp files. Should be quite difficult for a program apart
from firefox to get my video data this way. Perhaps some program that
can read the RAM but where should it read? Your "... | tee ..." looks
interesting but is there a chance that this does work outside of
firefox?

I installed the add-on of your second link. It offers different videos
for downloading than the Downloadhelper but unfortunately not the
video I'd like to download. Could be a good idea to try some other add-
ons.

That's a good idea, using wireshark. I should have thought of that.

Darn!
Try looking for a URL http[s]://.* or a link <a href=\".*
Sometimes you get 'taken to' another page and _it_ has
the URL you want.

Probably true, but not relevant to what I said above. What's
happening ordinarily (I am guessing) is that it is re-directed
to a file called /dev/null after you view it and it vanishes
into that bit bucket. What you need to do is re-direct to a file
called something else.
This _can_ be done, even if I can't tell you exactly how.
There are apps that capture whatever is on the screen to
a file...

No. There are other programs that display flash videos. Like
the GNU program, gnash:

Don't know if it has a console interface, though.

What I did while the video started:
$ find /home/sidux/.mozilla/firefox/972jgagx.default/Cache/ -mmin 1 -
exec file '{}' \+
$ find /tmp -mmin 1 -exec file '{}' \+
Again the only videos I found were commercials and *not* the main
video.

Perhaps that's the way firefox finds the URL.

I already tested "ffmpeg -f x11grab ..." that captures the X window
but it didn't record sound.

Sounds good. While googling I found dump-gnash which has a dump
option. But it doesn't come along with the gnash package. Hopefully I
can find the source code somewhere.
By the way: If anybody doesn't believe how difficult the whole thing
is just go to http://www.prosieben.de/tv/tv-total/video/ and try

It looks to me that what's happenning is the plugin is displaying
the video as it receives it and then sending what you've seen
to /dev/null. You want to redirect it to a regular file instead.
So I don't think you are going find it anywhere on your computer.

Has the OP tried the 'httpfox' add-on for firefox
(https://addons.mozilla.org/en-US/firefox/addon/6647) ?
It lets one see the actual HTTP GET/POST sent by firefox to
the webserver. The video URL will be somewhere in there...
It might however be useless as the content providers sometimes
use temporary (ie. unique, dynamically created) URLs for
their content, so that people like the OP cannot pass around
deep links to their content, thus bypassing the ads on their
site.

Not if it's live streaming. In this instance it gets streamed and played
and immediately discarded. Empirical proof: go watch a BBC iPlayer live
stream for a couple of hours.

Sidney is right. Even if it is a live broadcast, the stream *must* be
buffered somewhere. It does not rush from your ethernet adapter to
your video RAM. It is always buffered on disk.
If the player you are using purges the played content from its cache,
then this is a deliberate "feature" of that player - presumably
built-in for the sake of copyrights - but then it is up to you to use a
different player if you want to save the stream.
You are after all trying to circumvent copyright protection measures, so
it would be pointless that you're sticking to a proprietary stream
player with the copyright protection built-in. Capture the stream and
buffer it. There must be a cache. Create a hardlink to it - this is
not a trick I've invented, someone else deserves the credit for it - so
that when the cache is deleted by the player, you'll still have the
original cache because it has a second filename. Then just move the
file from "/tmp" (if it resides there) to your home directory and open
it with a media player of your choice to watch it/listen to it again.

No. You are trying to circumvent copy deletion measures. By giving you
permission to download the file they gave you permission to make a
copy. Once you have done so that copy is your property and you have the
right to preserve it and view it as many times as you wish. They try to
trick you into deleting the copy after you have viewed it once, but if
you outwit them and save it you are not infringing their copyright.
Note that you do _not_ have the right to make additional copies.

I'm not a lawyer, but I always make/keep 2 or more copies of anything
important as a backup ;)

Agreed.

Video on demand may be buffered on disk. Live streaming is not buffered
on disk.

I'm perplexed as to why you're using the same word for two different
situations. In my experience, "downloading" popularly means the
transfering of a file from a remote (web)server to the local machine. I
would differentiate this from your first definition, by explaining that
(first definition) as being "streaming": the file content is transferred
from the remote server to the local system for the puposes of (almost)
immediately rendering it audibly or visually WITHOUT storage on that
local device.

The OP uses downloading to mean 'saving to a storage medium'
so I went from there.
A lot of people use it that way because they don't understand
that the file has already been downloaded or they wouldn't
be able to view/listen to it.
They think they've 'gone to a website', which is a very
misleading expression. The opposite is true: The
website comes to you.

It's HttpFox and I just tried it. Looks similar to wireshark but only
for http and I got some information. Again those ads and a redirection
address which I think leads to the main video but there's no video
format ending (like flv or mp4) I could use for downloading. If I had
a proper address I could use wget. I also copied this address to
Firefox but nothing happened. But thanks anyway.

I found nothing new with "about:cache".
I also tested a short video (3:33 min) that I couldn't download. Of
course I don't know the cache size required but it should fit.
I was serious when I asked if somebody has visited "http://
www.prosieben.de/tv/tv-total/video/" and tried downloading a video.
Otherwise I'm afraid it's getting a bit too theoretical.

But those are two different operations.
That should be quite apparent to you by now :-)

Which of course makes the title of this thread nonesense, since by your
definition you cannot download without saving.

I'm not in Germany and so I cannot view anything other than the initial
advertisement.

Their content is not available to viewers who come from IPs
outside Germany. Only the german readers of this newsgroup
might be able to test the above URL and hopefully help you.

It's just another sign for their restrictive policy.

I tested the gnash plugin for Firefox and it works fine on youtube and
some other sites. The video is displayed and I can record it while it
is streamed. But again it fails on prosieben.de: The video didn't even
start so there's no chance for recording it. I only know of another
alternative to Adobe Flash: swfdec which is no longer developed
though.

Please have a look at:
http://en.wikipedia.org/wiki/Download
(... The use of the terms uploading and downloading often imply that
the data sent or received is to be stored permanently, or at least
stored more than temporarily. ...)

The title isn't correct even if downloading just means receiving data
since there's no downstreaming without receiving data. It's because my
definition wasn't complete.
Please have a look at:
http://en.wikipedia.org/wiki/Download
(... In contrast, the term downloading is distinguished from the
related concept of streaming, which indicates the receiving of data
that is used near immediately as it is received, ...)
I chose the title because "recording a streaming video" (e.g with
gnash) is done real-time (i.e. the whole process takes as long as the
video is in terms of time) and "downloading a video file" normally
takes less time (and depends on the speed of the connection). And
because of another thread which discussed the video download of that
particular web site came to the conclusion that a download is not
possible and to avoid lots of comments about I should use Firefox
download add-ons like FlashGot (which don't work) I added "not
download". To complete my definition I have to add something like
there must be an actual link to a file I can access. At least that's
what happens when a window pops up and I could choose between opening
or saving a file: there's a file name. Perhaps that's not the way
other people use this term but I just wanted to explain what I
associate with it.

Why are you obsessed with a site that seems to have security
software that is out of control?

Yes. but those are obviously, in many situations, two different
operations.
I am beginning to think that you are genuinely dense.
Go away.
Done.
