I'm a long-time C & Unix hacker who believes strongly in interoperability and likes to take pictures. If something is broken, I'll try to fix it.

comment how can I batch extract audio from mp4 files with ffmpeg without decompression (automatic audio codec detection)?
Your automagic example breaks with filenames that have spaces in them because you didn't quote $file in the ffprobe sub-statement. Changing it to: for file in *mp4 *avi; do ffmpeg -i "$file" -vn -acodec copy "$file".ffprobe "$file" 2>&1 |sed -rn 's/.*Audio: (...), .*/\1/p'; done Fixes that.

comment Choppy Flash Audio
Works fine in 12.04 on my HW, latest set of patches. Aside from the whole screen size mishegas that Unity has given me [us] (which goes away once xbuntu has been installed and selected for my login session), the only other problem that I've seen is that the Unity UI sugar goes a bit crazy and can chew CPU cycles when the machine has been up for a while. That is, unfortunately, fixed by a reboot rather than just logging out and back in again.

I specifically pointed out atop because it will show process exits which can kill your performance without otherwise registering activity.

I'm running the same flash plugin and on a Core2, which is much slower than your box, yet I'm not having any problems. How old is your system drive? The original HDD in my system started slowing down and giving choppy access which blew performance out of the water - replaced it and everything's much better now.

So, what have you done in the meantime? What else do you have running? Who is hogging the CPU? That's almost always the cause of choppy video, especially when you have a local copy cached. htop and atop are your friends.

It's very easy to disappear it … and some websites like to do that to you in order to hide what they're doing. I only like to get rid of it when I want more vertical screen real estate.
