I use ffmpeg to convert my files, but when I do so, I lose the keyframes metadata from my flv files. The command I use right now is: $/usr/local/bin/ffmpeg -i %s -ab 96k -ar 44100 -b 500k -r 25 -f flv %sHow can I avoid ffmpeg to delete the keyframes info?

View 8 Replies View RelatedI've created some time-lapse videos from photos, using this command: ffmpeg -i IMG_%03d.JPG -s 1440x1080 -sameq video.MP4
And it worked great. Now I want to join several of these time-lapse videos to make a single, longer video (all the input videos have the exactly same format). I already tried using: cat video1.MP4 video2.MP4 > stitch.MP4
but the output ends up being equal to video1.MP4, I don't want to transcode nor changing any parameter of the video, I just want a end-to-end stitching, as if those videos were on a playlist.
so i've just installed Burg loader in a PC which dual-booted Windows 7 and Ubuntu 11.04 with no problem using grub2 in the past. But after i installed burg it just boots up straight into the Windows OS and Ubuntu is nowhere to be found. Is there a way to restore grub2 preferably without having to lose any files?

how can i merge two files with ffmpeg?
one is : /home/pt/t/pa1.flv
the other is : /home/pt/t/pa2.flv
1 o merge with ffmpeg
ffmpeg -i /home/pt/t/pa1.flv -i /home/pt/t/pa2.flv -vcodec copy -acodec copy /home/pt/t/dd.flv
the problem is: the merged file ( /home/pt/t/dd.flv ) just contain one file--the first one
/home/pt/t/pa1.flv,there is no the second file--/home/pt/t/pa2.flv in the /home/pt/t/dd.flv

I'm running ClipBucket on my Ubuntu 10.04 LTS server x64.Conversion of AVI to FLV works just fine, however when I try to upload an MPG file, it fails. Apparently I should recompile ffmpeg to allow for MPG > FLV conversions.

I run computers that do distributed computing for cancer cures. I'm experimenting with running a version of Ubuntu that is specifically written for DC and can be run on bootable USB drives. The one I'm running now on USB works fine but there is one issue I need to solve. When I reboot the system or it restarts from a power failure I have to reattach the cruncher client(BOINC)to the each project and I lose whatever work units that have started. I don't have this problem if I use a HDD. I'm using an 8GB USB drive with 6GB of DDR3 12800 memory. Can someone explain to a linux novice how to overcome this issue?

View 2 Replies View RelatedI'm using Xterm. While running a prog/command if I scroll up and reading something on the screen, the xterm view resets to bottom if there is some output from the running command.
I tried enabling/disabling jump scroll, asynchronous scroll, scroll to bottom on tty output options of Xterm with no avail. In one way or the other way, the screen is scrolling or resetting to bottom if there is some output to screen.
I want to stop this behavior and the scroll should work as if it is in Konsole. The new output to screen should simply add at the bottom and the current viewing point should remain unscrolled. pls let me know if there is any working solution for this xterm problem.
I have created a linux machine and installed some softwares on it with root user privileges . I used to login with root user credentials for doing the various task.
Later i have realise that this is not the best practice to follow and there should be a new user with less privileges to be created for doing the day to day task.
I have read the steps to create the user but will that new user sufficient enough to do the task that i m doing it through root user?
Will my software allow the new user to work on them?
I would be glad if someone points me to a guidelines on what should be my next step?

I'm thinking Linux is the way to go but I don't know what distribution to use. I don't know anything about their hardware other than it is an old laptop. I don't have a lot of experience with Linux, but I would think that without sudo there is not a lot of things you can break.
What would be a good Linux dist that has everything out of the box?

I am looking for an option to convert .vob file to mp4 format. Command "ffmpeg -i S.vob x.mp4" is giving error message "[libfaac @ 01cac110] Unable to load libfaac.dll". I tried to convert in other formats like .avi with the same command and got success. Conversion is decreasing the quality like hell. Though size of the file after conversion is as big as original then why this bad quality. Some where I have read if I will not specify any argument it will keep the quality same but here it is not happening. Not sure why....
