avconv used to work fine for me in 13.10, but now it doesn't. I'm using it in the same way as before, for example:

avconv -ss 1971 -t 2216 -i x.mp4 -vcodec copy -acodec copy -metadata track="7"  "d32.mp4"

terminal output:

The length of the output should be 4 minutes and 5 seconds, but it is over 30 minutes. Does any one know what is going on or have a suggestion?

I have several large videos that I want to split into parts. The only way to do that I know is to split one part at a time with OpenShot. I have to split, wait a long time, delete the part, split the next part, ...

Is there a better way? I tried to google but it seems all the methods also require splitting one part at a time. This is really inconvenient as I need each video to be split into 20-30 parts. I want to be able to just mark all the split point and come back later and find it all done. Does anyone know a way?

UPDATE: Now I'm working on a command line solution. I tried this command but the only problem is that there are few seconds of where the video freezes in the beginning (and end) of each output split.

avconv -i x.mp4 -ss 00:00:00 -t 00:01:00 -c:v copy -c:a copy out.mp4  -ss 00:01:00 -t 00:01:00 -c:v copy -c:a copy out1.mp4  -ss 00:02:00 -t 00:01:00 -c:v copy -c:a copy out2.mp4  -ss 00:03:00 -t 00:04:00 -c:v copy -c:a copy out3.mp4

Until yesterday I was having Workstation 9 startup with ubuntu (just added an entry in the Startup Applications GUI). When I start my ubuntu, workstation comes up and every thing runs fine.

Then, I upgraded to Workstation 10. Every thing appears to work with no isues, EXCEPT, it will not startup my virtual machine when it is launched at startup. It shows these errors:

Could not open /dev/vmmon: No such file or directory.
Please make sure that the kernel module `vmmon' is loaded.

then,

Failed to initialize monitor device.

then,

Unable to change virtual machine power state: Internal error

Otherwise, if I just try to play the virtual machine again (by pressing play), it works.

Maybe it is a VMware bug.

Please, any advise?

I would like to define a keyboard shortcut that resets my wireless adapter. I know it is possible in the terminal with sudo ifconfig, but for the keyboard shortcut, I can't provide the password for sudo.

Are there other commands that can do the job without root privileges?

I'm Running 13.04. When I try to play .ape files in vlc, for some reason it plays only a split second then quiets repeatedly.

This a screen shot of the output when run from terminal. It keeps saying buffer way too late nothing to play ... nothing to play buffer too late

On this machine, other media players play vlc fine.

on the same machine, in another installation, vlc in 12.10 plays ape with no issues but all other media players struggle with what I have now.

please help.

I have been getting this occasionally since I started using Ubuntu. Does anyone know a fix?

I don't understand why my custom hotkeys aren’t working. The commands work fine on the terminal and my choice of hotkeys do work for other commands ( I tried gedit).

This is what I did, only the first one works:

the full command is

echo -n  "pause" | nc -U /home/me/.local/share/vlc/vlc.sock

IT WORKS ON THE TERMINAL

In terms of stability and performance, is it better to clone the entire HDD to a new computer or start with a fresh install?

btw, much of my production software is in a virtual machine, which can be easily moved.But still, my ubuntu baremetal install (non virtual) is highly customized and tweaked.

I can't assign ratings! What is the rating tab for? It has always been blank and doesn't change.

Edit: Sorry for omitting the details. Please don't criticize my choice of music.

can't do anything to the ratings, for any kind of media file.

proof that I'm using Ubuntu -- apparently, my coming to this forum is not sufficient to infer this.
