[gentoo-user] Downloading Flash videos

[-- Attachment #1: Type: text/plain, Size: 681 bytes --]

Hi All,

I've been trying to download different flash embedded videos like:

http://video.google.com/videoplay?docid=4191382246884244677

http://www.youtube.com/watch?v=hjV0Gws-BVM

etc.

I have used VideoDownloader with Firefox and FLV Downloader (which didn't 
work) and Video Manager  with Opera.  It seems that the downloaded video is 
very jumpy (drops huge number of frames) when played back using xine/gxine.  
So I thought of using wget to achieve the same effect but without all these 
helpful GUIs, but cannot see what I should be downloading when I look at the 
HTML source of the YouTube web page.

What would you advise on this?

 How about net-misc/youtube-dl?

Hm. That shouldn't be an effect here, since those plugins/widgets don't
capture the stream off the network device (packet socket), where
packets could get lost. FLV usually doesn't react good on dropouts
either, it's not streamed via UDP for that reason, I guess. So I'm not
quite sure if you can overcome the jumps...

But FWIW, my method is to "start" the video (i.e. clicking on it so the
flash player opens), then immediately pause it. When the player's "gray
bar" filled up, the FLV is waiting for a quick "cp" on the command line
as temporary file in /tmp (named "Flash<random string>"). Some flash
players utilize the browser to download the FLV, then it will be in the
browser's cache directory. Works all the time, I don't bother with
extensions/plugins anymore...

BTW, my preferred player for those is vlc. But it should work with any
player linked against a reasonably recent ffmpeg.

Use mplayer...
I tried it with same plugins for firefox, and it worked like a charm.

As Hans-Werner already mentioned, most embedded (flash)-videos are 
stored temporarily on disk in /tmp or in the browser's cache at least 
here with firefox. So just wait until it is loaded and don't close the 
browser window then copy it to where you want. Btw. YouTube and 
GoogleVideo store them to /tmp.

They play well with mplayer, xine, vlc which i use, others will also work.

Regards,

Daniel

Thank you All,

Good tip, should have thought of looking into /tmp, or the browser cache.  I 
did some comparative playbacks and xine/gxine drop frames like mad, while 
mplayer manages a pretty respectable output.  Therefore the problem seems to 
be not on the download but the playback.  Hmm, why would that be?

default video driver. I bet you have a ATI video card.

open site. Wait until flash starts to load
ls -lhtr /tmp
the last file, starting with FLASH is the one.
Wait for it to be fully loaded, copy it somewhere.

Easy. No plugin needed - and honestly I am surprised that a lot of plugins 
can't do that right.

Actually, when using mplayer to play flash videos, you may find that some
of them have audio/video out of sync unless you use the "-correct-pts"
option. Alternatively, use ffplay.

You can also make a hard link (NOT a symlink) to the /tmp file while
it is loading, and when it is done and deletes the temp file, it
deletes the original yuckky name only.  You can come back at your
leisure to pick up the remaining linked file, and you can create it
with a better name too.

Use UNIX inode magic, it's pretty handy.

  There's an automated way of doing this.  I've written a bash script
that will find flash video files in the current directory *REGARDLESS OF
THE NAME*, and move them over to a specified directory with sequential
names, i.e. mm000.flv, mm001.flv, mm002.flv, etc.  Here's the setup...

1) mkdir ~/mvflv

2) save the script below as ~/bin/mvflv and make it executable.  This
bash script is released under GPL version 2.  You don't know me, so you
may want to wade through the code to ensure that it doesn't do anything
nasty, especially in the backtick expansions.  (I originally wrote the
decrement(), increment(), and getnextversion() functions for use with my
system backups, so that they would be sequentially numbered).

3) cd to either /tmp or Firefox's Cache directory and execute mvflv
The script lists each file it moves into ~/flvfiles

##################################################################
#!/bin/bash

decrement() {
  echo $(( $1 - 1 ))
}

increment() {
  echo $(( $1 + 1 ))
}

getnextversion() {
  NUMBER=

  while [ ${DIGITPOINTER} -lt ${1} ]
  do
    NUMBER=${NUMBER}0
    DIGIT[${DIGITPOINTER}]=0

  while [ -e ${2}${NUMBER}${3} ]

    DIGITPNTLEFT=`decrement ${DIGITPOINTER}`
    DIGIT[${DIGITPOINTER}]=`increment ${DIGIT[${DIGITPOINTER}]}`
