[gentoo-user] Tweak nice
Hi! I noticed a very annoying behavior. I've got a headless server (Athlon 64 X2) which primarily acts as a personal video recorder using mencoder and at-daemon. In its idle-time it's supposed to run a dnet-client. Then I've got a laptop (64bit Celeron, single core) on which I play those video files from my server over NFS. So far, so good. My problem is: Neither of them can handle recording/playing video while there is any background activity. That means I have to stop the dnet-daemon and suspend any emerges on my laptop. If I don't, both mencoder and mplayer loose sync of audio and video and drops frames. Apparently a nice-setting of 19 is not enough to keep daemons and similar stuff as strict idle activity. It still gets a fair amount of cpu-time. Of course, I could give mencoder/mplayer real-time priority (nice -n 20) but that would need them to run in super-user mode which should be unnecessary for such a simple task. Long story short, can I somehow tweak the scheduler to be more aggressive when it comes to high nice-levels? Thanks in advance!

[gentoo-user] md5sum for directories?
Hi there,
I'm in the habit of backing up customer data by booting from knoppix,
connecting a portable hard-drive and copying with `cp -rvf`.
When this has finished I connect the portable hard-drive to my
desktop machine, copy the directory of data from it to my homedir,
and make a zip file of the directory.
I've done this loads in the past, and never been aware of any file
corruption, but I guess I'm just paranoid today. Perhaps I shouldn't
use the -v flags during my copy - it's reassuring to see the files
being copied, but what if I overlooked a bunch of errors in the
middle of all those thousands of "copied successfully" confirmations?
What if something has gone wrong during one of the two copies?
So my question is:
Is there any way to check the integrity of copied directories, to be
sure that none of the files or sub-directories in them have become
damaged during transfer? I'm thinking of something like md5sum for
directories.
It occurred to me that one could run `find . -type f -exec md5sum \{}
\; > file.txt` on both machines and diff the outputs, but some of
these directories contain many thousands of files, and I'd imagine
that mdsumming of all these could take some time.
Does anyone have any suggestions, please?
Stroller.

I would expect most people these days to be receiving some kind of digital signal - DVB-T using an aerial, DVB-S using a dish or DVB-C via cable. Here in the UK, for example, it would be most common to receive DVB-T "Freeview". Receiving a digital signal requires no encoding, practically no processor resources, as the DVB signal is just mpeg, and the card is simply dumping the stream to hard-disk. Are you playing back the video across the network? What processor / RAM configurations do your PCs have? What hard-drives? What size are the videos (pixels) and what format (encoding, bitrate) are they stored in on your hard-drive? I think you have to demonstrate that the problem is processor-bound. My immediate thought upon reports of stuttering is to question disk or network throughput. Stroller. -- gentoo-user@lists.gentoo.org mailing list

Well, in that case cp will have a nnonzero exit status. Look: $ ls -l total 12 -rw-r--r-- 1 kermit users4 2008-02-24 12:30 a -rw-r--r-- 1 kermit users 12 2008-02-24 12:30 b drwxr-xr-x 2 kermit users 4096 2008-02-24 12:30 destdir $ ls -l destdir total 0 $ chmod 000 b $ ls -l total 12 -rw-r--r-- 1 kermit users4 2008-02-24 12:30 a -- 1 kermit users 12 2008-02-24 12:30 b drwxr-xr-x 2 kermit users 4096 2008-02-24 12:30 destdir $ cp a b destdir cp: cannot open `b' for reading: Permission denied $ echo $? 1 $ ls -l destdir total 4 -rw-r--r-- 1 kermit users 4 2008-02-24 12:31 a I think this should hold for the majority of cases/errors cp might encounter during the copy. Of course, this does not detect a succesful, but somehow corrupted, copy (which should be exceptionally rare, anyway). > So my question is: > > Is there any way to check the integrity of copied directories, to be > sure that none of the files or sub-directories in them have become > damaged during transfer? I'm thinking of something like md5sum for > directories. I'm not aware of any such tool (which might exist nonetheless, of course). However, on the filesystem, the objects that we call "directories" are just index files holding filenames and pointers to inodes. Running a checksum on the directories themselves would not guarantee against corruption of any of the contained files, since file data is not contained in the directory. Thus, to be accurate, such a tool would have to scan the directory, find each file, and perform a checksum on it, which would result in something not much different from the find command you suggested, in terms of resource usage. -- gentoo-user@lists.gentoo.org mailing list

It's a PCI-card for analog TV (ordinary cable with about 20 channels). It doesn't output mpeg but raw video/audio so I have to encode it. I use h.264 (1 pass, 2 threads) and lame. The settings are tweaked to allow 25fps and a good overall quality. I could give you the settings but I don't think they're really important. The load is somewhere around 1.3 to 1.8. Of course I could tweak it to achieve 25fps even with dnet-client in the background but that would cost me quality and wouldn't fix my problem on the notebook. On my notebook, CPU-utilization is just around 50%. There is no apparent bottleneck on my setup. The 100MBit network is fast enough to transfer the files while playback is running even without caching. I'm decoding them on my notebook. If there were a bottleneck other than CPU-scheduling, it would hit me every time, not just when another process demands CPU-time. signature.asc Description: This is a digitally signed message part

If you run dnetc with nice 19 and simultaneously something that uses as much CPU as it can get (like a fractals generator) at nice 0, you will see that dnetc still uses around 6% CPU. But it does go down to 6%. The remaining CPU should be enough for watching video. Disclaimer: I have never used mplayer on a 64bit system. It might have issues there. Since you are playing the video over NFS you do so over the network. Maybe a stupid question: You do use FastEthernet without any hub, right? Switches are alright but hubs are evil. A possiible work around might be to increase the buffer in mplayer to something around 1MB.

I'm thinking of something like md5sum for directories. I use rsync for this and would suggest you look into it. You can tell it to compare files based on checksum (which is slower) and the real beauty is that if there is a file that is corrupt or otherwise not the same as the source it will copy just that single file to your backup disk. Test it by deleting a random file somewhere in the backup tree.. rerun your rsync command and the file is copied back. man rsync -- Christopher -- gentoo-user@lists.gentoo.org mailing list

And yes, it does go down but not far enough, especially because there are two such processes (one for each core). By the way: Another daemon who's causing problems is clrngd, creating 100% CPU-utilization every 4 minutes for about 1 minute. I neither use a switch nor a hub, just a good old crossover cable. In fact, I used to let mplayer create a 8MB cache but without background activity it was useless and with it, it's got eaten up too soon. Mencoder seems to utilize a queue/fifo/whatever-you-might-call-it by default but that doesn't help if it doesn't reach 25fps. Since nobody seems to have an idea, maybe someone can tell me how I allow processes with real-time priority (nice -n -20) to be started by an ordinary user?

Re: [gentoo-user] Switch between sound cards?
Grant, If you want to do a complete switch then you would change your USB card to index 0 and restart Als which would make the USB card the default since card 0 is always the default for Alsa. On the other hand, if you wanted to just leave the onboard card as default and send audio from a specific application to the USB card you would tell the application to use hw:1 explicity, either in the command line when you start the app or in an application's config file. On my system I let all my web/browest audio go to the onboard sound card but I send all my CD audio directly to my good card using Aqualung and configuring it from the command line. (Actually in my launcher.) to the best of my knowledge there has never been a way to simply switch sound cards on the fly in Alsa. I've requested this sometime back but the developers haven't shown any interest.

No matter which one I set to index=0 and which to index=1 the sound always comes out of the USB card. BTW, what sound card are you using?

On my wife's machine, and out MythTV backend server, we use the intel-hda oinboard sound chip for most audio but we also have an external usb sound card that converts from USB to TOS link which I use to drive our home theater receiver. I'm putting the alsa file at the end of this post. Note that on this machine when we want to play audio using Aqualung through the onboard device this is the command in the Gnome launcher: /usr/bin/aqualung -o alsa -d hw:0,0 while if we want to play through the USB device we use this: /usr/bin/aqualung -o alsa -d hw:1,0 Not sure why you'd be having trouble. We use this technique on Aqualung, mplayer, xine and MythTV. The basic idea works once you get it under control.

Hot switching of audio streams between devices is really cool! _r
