General :: `mencoder` Captures 10 Minutes Of Audio In Less Than 10 Minutes?
Mar 15, 2011
I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69
real 9m54.886s
user 0m5.536s
sys 0m1.740s
$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?

Whenever I try to play AC3 audio, after a few minutes, the audio dies and never recovers. This doesn't occur with mp3's / etc, although once the audio dies because of AC3, it's gone for good. So this is probably related to surround sound(?).
After I lose audio, speaker-test produces
Code: Select allWrite error: -5,Input/output error
xrun_recovery failed: -5,Input/output error
Transfer failed: Input/output error
K-Mixer won't even open afterwards. I flipped from GNOME to KDE because of this problem (PulseAudio freezed the system entirely).
Additional info:

i am using ubuntu studio karmic and i have a digitech vx400 audio effects pedal which serves as an audio in/out midi in/out device via usb. i can sucessfully set it as the system sound device in system>preferences>sound for both input and output. but, when i play audio through it it only works for a few minutes before the sound stops completely. if i leave the system settings set to the internal sound card and configure jack audio connection kit to go to the usb device, i get the same results on the usb sound. a few minutes of playback at the most.i can restart sound with either "pulseaudio --kill && pulseaudio --start" or "alsactl init" in either situation. just requires restarting the programs. same results after restarting. i think this is alsa related as i have both the system sound and jack using the alsa driver, but i don't truly understand the relationship between pulseaudio and alsa.

I am new to Ubuntu. I had it installed on an 8gb Medion USB key and for some reason Ubuntu keeps freezing every few minutes. The application that I would be using would freeze for a few seconds.

I guess in most cases when extracting a tar achive ,we will get a directory with the same name as the archive file but different suffix. but in some unlucky case, as I met today, after extract a tar bar I find lots of files spread in the working directory, which is really nuisance.so what I want to learn from you is that how can I move thoes newly created files ? I know it should be some "find plus rm" fancy approch there, but I don't know exactly how.

I am having an issue with my wireless connection dropping about every 2 minutes (web pages timing out), then working for a couple of minutes then dropping again. The connection icon in the task bar says I'm still connected at about 70%.I have a dual boot system and the wireless works fine in opensuse but not in Ubuntu 10.10 I have an Asus G50vt-X5 laptop but I am not sure about the wireless chipset.

made a script with funtions, everything worked until 15 minutes ago, and i can't figure out what did go wrong.I think it has to do something with the 3 first rules of code... but for my opinion that should be fine (i used '777' just to be sure)
Code:
test_mount() {
$touch /current_mount

If I ssh to a remote machine and then lose internet connectivity, the session freezes. I can't control-c or otherwise abort and go back to my local xterm or terminal prompt but if I wait several minutes it will do so.
There must be some way to force it to abort the remote ssh session when connectivity is lost. I'm on a Mac but I believe this happens on cygwin or linux as well.

I am planning on running a script once every five minutes, and the syntax that comes to mind in doing this is the following:
Code:
5 10 15 20 25 30 35 40 45 50 55 * * * * /apps/<script>.pl
Is there a better syntax to use to accomplish this task, or is the above example the way to go?

I'm running a fullscreen display app which shows a 3D scene in OpenGL. The app runs continiously throughout the day unattended.
Here's the sequence of events in how it's loaded:
1) The computer is turned on, and boots into F11 (x86_64)
2) A non-privileged user is automatically logged on
3) The gnome startup applications list contains an entry for a loading script
4) The loading script waits for the network interface (eth0) to ccome up, then starts the display program
This all works just fine, except that about 30 minutes after the computer is turned on and the app starts running, the screen blanks out. Attaching a mouse to the system and moving it around a bit brings the screen back to life. Likewise, SSHing into the machine and killing / restarting the application works as well. Once either of these fixes has been performed, it runs flawlessly for the rest of the day.
I have turned off the screen saver, and set the power settings for monitor shutdown to 'never'.

I have a troubling issue. I log into Linux Mint 9 (fully up-to-date) on my Samsung Q320 laptop with power connected and after a few minutes it seems like the entire X session dies, I am logged out, all processes are killed and I am presented with the normal GDM login screen. When I first installed Linux Mint, this never happened. I have the NVidia closed-source driver installed and when the system logs me out, it immediately restarts X loading the NVidia driver which flashes the logo on screen. This all happens instantaneously, so it is not a reboot of the machine, just a restart of the display manager it seems.
There does not seem to be any cause for this. I have disabled all screen saver and power management settings that may lead my system to auto-logout of Gnome. The system log doesn't indicate anything unusual happening. Confused about where to to take it from here bar and fresh install of the OS. Perhaps there are some X11 logs I should be checking.
Update: Moved to Ubuntu 10.10 and its recommended NVidia driver and have not experienced this problem since.

Our home broadband (TWC/RoadRunner/San Diego) intermittently drops out for minutes at a time. In WinXP, I had a logger that would ping one or more sites (e.g. Yahoo.com), log the ping times, and display the data in an interactive graph. This was very useful in showing the ISP tech (I didn't know about Shibboleet then).The problem is still unsolved after two visits, but now I'm using Ubuntu 10.04. I'm looking for a similar tool. I'm a Linux newb (i.e. "just write a script" isn't helpful at this point), so I'm hoping for something user-friendly with a GUI.Can anyone recommend a Linux utility that...Logs ping timesDisplays results graphicallyDoesn't require advanced Linux skills to set up

I'm running Fedora 14 and set the screensaver (in System>Preferences on the Gnome GUI) to activate after the computer is idle for 30 minutes. After the screensaver is activated, and a press a key or the mouse, the screen is back to normal -- no problem.After the screensaver has been activated once, however, it comes back on very quickly -- usually in 2 or 3 minutes if the computer is idle. The only way I have found to correct this (and set activation back at 30 minutes again) is to log out and back in again.How can I correct this, and automatically set screensaver activation back at 30 minutes each time the normal screen is reactivated?

I have just installed ubuntu on my second laptop. However, this one is giving me some grief. After several minutes, it completely locks up. No mouse, keyboard, anything. Just frozen solid. I had some issues installing it, and got around them by checking something like "nolacpi" and "noacpi" with the live cd, but now I don't know how to re enable those options. I'm quite computer savvy, but am still learning how linux works. For refrence, this is the system specs:
HP Pavilion Zx5000
Pentium 4 3.06GHz
ATI Mobility Radeon 9200 GPU
1GB RAM
60GB IDE Hard drive

I have to type this quick because Ubuntu will lock up on me.The screen goes black, the cursor does NOT move, and the only way to recover is to do a hard reboot. This happened when I had windows XP installed as well, only it would reboot the machine after 5 minutes.I barely have time to open one program and it locks up.Could this be a hardware issue?I tried taking out the video card I had bought, thinking it would solve the problem, but it does not.
