Is there a command line utility to tell me about what's inside a video file? Say I have a .mpg file. I want to know about the video stream and the various audio streams, the codec used for the video stream, the bitrate of the video stream, and so on.
View 5 RepliesI am trying to find a linux cmd line utility that will read info from an iso file. The problem I have is that the file is always corrupt so I cannot mount it because I only have around 100k of it but all I need is to extract the headers of what the iso contains. how I can achieve this I have searched the internet with no look at all.

View 2 Replies View RelatedI wanted to share this nifty technique I came across for capturing video using the command line. The problem: I have a bunch of old VHS tapes (remember those...?) and need to get them digitized. I have a VCR, and a Dazzle Hollywood DV Bridge which captures video to DV over Firewire (IEEE1394). I first tried using Final Cut Pro, but it wouldn't capture, perhaps because it expects a controllable DV camera, and the Dazzle isn't a DVC device. I then tried my other favorite video editing app, Kdenlive, but it seemed to have the same problem.
I took a quick stab at the other common editors in the repositories (Kino, Openshot, etc.), but no luck with any of them. Then I remembered the dvgrab command, and gave that a shot and it worked, giving me a nice .dv file. However, DV makes pretty big files, which I wanted to compress down to something more manageable. Since I was going to be digitizing hours and hours of tapes, it would be great if I could compress while capturing. A little more googling and I had the answer - you can pipe dvgrab directly into ffmpeg! Here's the command:
Code:
dvgrab -format dv1 - | ffmpeg -f dv -i - -b 2000k -ab 512k -y output.mov
the first part starts the capture, in DV1 format, and outputs it to a pipe file. usually you give dvgrab a filename, like
Code:
dvgrab -format dv1 capture.dv
the second part does the encoding:
-f dv: use DV format
-i -: input from the pipe
-b 2000k: video encoding bitrate of 2000k/sec, high quality
-ab 512k: audio encoding bitrate
-y: overwrite file if it exists
I didn't set the codec explicitly, for Quicktime it defaults to MPEG4. This worked great, capturing a 2-hour tape into a high-quality quicktime around 2GB. But I also wanted to be able to view the capture while it was going. Since I left the field monitors and audio splitters at the office, I had to figure out how to do this in software. Turns out that the "tee" command does exactly what I needed - the shell never ceases to amaze! Here's the full command:
Code:
dvgrab -format dv1 - | tee >(ffmpeg -f dv -i - -b 2000k -ab 512k output.mov) >(playdv --disable-audio --no-mmap)
tee uses the
Code:
>(command)
syntax to pipe simultaneously to multiple processes. The only thing that didn't work was audio playback, which was choppy and introduced errors in the capture file. I think a little tweaking with the capture rates could fix that.
Now I am use Xfce4,some window's tittle are different from the running commands!
So I hope to know which command can do like FvwmIdent !
I want to take consecutive screenshots of a video using command line operations but I can't seem to find accurate documentation on different websites.Does anyone know how to do this using vlc, totem or another program?I've used ffmpeg as well, but then reencodes and splits the video file. I just want to take consecutive screenshots.

View 1 Replies View RelatedI adjusted some settings in the desktop settings folder in KDE. I had only one user account on the machine. Next time I rebooted I could not log into KDE (it kept bombing out). I had to log into the console. Finally I managed to create a new account with useradd but this user cannot sudo
My problem is that my home directory is encrypted, so I need a new user with sudo privileges to delete all the kde files and folders in my original users home directory so that I can start with a new KDE setup (which won�t be a bad thing since I tinkered a lot).
How can I add sudo privileges to the new account (I presume I can do it by logging in with my sudo account in a terminal login?

[Question]
By (first step) doing: pcmanfm --set-wallpaper /point-to-new-wallpaper, it change the configuration to the new wallpaper, then, my question is: What is the most correct way to "refresh the desktop screen" (by command line) so that the new wallpaper is then displayed.
And by (second step) doing: lxsession-logout, and choosing 'Logout', the new wallpaper is displayed after the new login. No problem here. Is there a (most correct) way to completely change the picture and activate it by command line (without user intervention)?
Does anybody know what has happened to Kino - the video capture utility? Used to be packaged by packman for Opensuse but doesn't seem to be available for 11.2.
Is there an alternative I can use for video capture - or has packman just not gotten around to adding this yet?
On my Windoze machine, I use Replay Media Catcher 4 which runs silently in the background and captures any videos (FLV, AVI, MPG, WMV, etc) on any websites that I happen to go to, and saves them to a folder on my hard drive. Right now, if I want to save a video that I'm wathing from Ubuntu, I have to go to /temp, guess which file it is, and copy it after it downloads fully but before it finishes playing, otherwise Firefox deletes it from /temp right away. This is a pain.
Yes, there are screen motion capture utilities in the Ubuntu Software Center, but they're just screen scrapers that result in low quality copies without any audio. I want something that will actually capture the video stream and save it as a file. Even if it doesn't save all videos automatically like RMC4, and I have to right click on the video to Save As, that would be better than copying it from /temp at the precise exact moment.
