FFMPEG probs overread skip
Hello. When encoding a video for my android phone with ffmpeg I get a lot of overread-messages and a blurred playback. I use this command: ffmpeg -i myfile.avi -vcodec mpeg4 -s 480x262 myoutputfile.mp4. I don't need to convert sound. The sound is mp3.
When running command from first answer I get a video with acceptable video. Trying to use DrZaius twopass command fails.
Pass 1 runs to an end but when pass 2 starts I get this output:

Hello,
I am running into a rather interesting issue and I was curious if anyone may have seen it before or if anyone had any insight into what the problem could be. On one of my ACE 4710's (running sw A5(1.2) , I am running a fairly large number of layer 7 probes (71) across both 80 and 443. At seemingly random points in the day, the system reports that the probes are being skipped due to an internal error. I have seen this before when the system runs out of sockets for the probes, but I am not seeing any indication that is the case.
Here is an example probe config:
probe https CHECK-SOME-SITE
port 443
interval 10
faildetect 2
passdetect interval 30
receive 5
ssl version all
request method get url /some/url
header Host header-value "www.somesite.com"
expect regex "SOMEREGEX"
Here is the relevant output from ''show probe detail'
real : some-rserver
x.x.x.x 443 PROBE 3093610 1749563 1344047 SUCCESS
Socket state : CLOSED
No. Passed states : 49 No. Failed states : 49
No. Probes skipped : 479 Last status code : 200
No. Out of Sockets : 0 No. Internal error: 0
Last disconnect err : -
Last probe time : Tue Mar 4 16:45:03 2014
Last fail time : Fri Feb 28 13:30:37 2014
Last active time : Mon Mar 3 22:08:53 2014
Here are the log messages that are popping up:
Mar 4 2014 14:36:41 : %ACE-3-251014: Could not probe server x.x.x.x on port 443 for 4 consecutive tries - Internal error
The log messages appear for all rservers being probed for about 30 seconds, then they go away until the next event. Considering the probes are skipped, I do not believe this is actually causing failures at the moment. I have read that the ACE platform can only run 200 concurrent scripted probes, however I am at a loss as to how to check if that is what I am running into here. The real confusing thing here is the lack of internal error and out of socket counters.
Any help or insight would be very appreciated. Thanks in advance.
-EdHi Ed,
Two things:
Number of skipped probes. A skipped probe occurs when the ACE does not send out a probe because the scheduled interval to send a probe is shorter than it takes to complete the execution of the probe; the send interval is shorter than the open timeout or receive timeout interval.
In your case the interval is 10 which is little aggressive but still less than receive. But if the probe execution is greater than 10 seconds you may see probes getting skipped. Increasing the interval time by another 10 seconds can be helpful for testing to see if this mitigates the issue.
If you have UDP probes then you need to check this as well:
For UDP probes or UDP-based probes, we recommend a time interval value of 30 seconds. The reason for this recommendation is that the ACE data plane has a management connection limit of 100,000. Management connections are used by all probes as well as Telnet, SSH, SNMP, and other management applications. In addition, the ACE has a default timeout for UDP connections of 120 (ACE module) or 15 (ACE appliance) seconds. This means that the ACE does not remove the UDP connections even though the UDP probe has been closed for two minutes. Using a time interval less than 30 seconds may limit the number of UDP probes that can be configured to run without exceeding the management connection limit, which may result in skipped probes
Are you running any scripted probes?
It could be a stupid bug as well but i would suggest increasing the interval timeout and see how it goes.
You can also alo try debug hm errors/events/all etc and see if you get any detailed output there which can be sent to TAC for further investigation.

Movies skip in drive/like stop-and-go motion; transcoded FFmpeg do same!?
Hi folks. I have been ripping some DVDs as of late and I am in the midst of transfering them to Apple TV on my network. However I seem to have run into a problem.
Today I went to rip a DVD and then loaded into iTunes and trans to Apple TV. I was noticing that it was skipping a bit on my TV - not smooth playing in other words.
So I went back to my Macbook and started playing a disk in the Macbook DVD player and notices that when I play the movie stops and goes. Will play a second or two then stop then play then stop, almost like arecord skipping without missing any music. The drive seems to be a little noisier now too - making churning or turning noise as it reads and plays (skips).
What could this be from? This wasnt happening yesterday - I was able to rip a couple that didnt have this problem. Is the superdrive bad now? is it a software issue? Do I need ot reset PRAM?
Come to think of it I also was using FFMpeg to transcode some .avi movies into Apple TV compatible files and they didnt come out very well either, had to trash them. Since this is software based and not drive based, coul dmy issue be some setting or PRAM on Macbook itself rather than the drive?
OK I'm confused now!
Your help would be greatly appreciated!! as always...
JasonSo I dloaded VLC to play the movies before I rip them and I am getting the following errors for 2 different movies:
main: decoder is leaking pictures, resetting the heap
and
main: INPUTCONTROL_SET_POSITION(OFFSET) 11.2% failed
What do you think? Since I am not versed in this very wekk, is this a hardware or software issue? And how to remedy?
Thanks

Mediasource 5.10.38 mp3 track skipping prob
Hi !
I'm having a problem with Mediasource 5 since I upgraded to it.
I was listening to mp3s of a stand up show by Henry Rollins, and Mediasource kept skipping to the next track even though there was still a minute or so of the track left to play.
When I skip back to the track and drag the cursor, it plays the track fine, but the problem starts again with the next track...
It didn't do that on every track, it only did it on tracks that are 7 minutes long minimum.
I checked if everything was off (svm, crossfade...) and everything was.
I ripped those mp3s from my CD with Mediasource, so I really have no clue what's going on.
Any clue ?Are you playing the track from MediaSource's PC Music Library or from MediaSource's My Computer?

XtremeGamer Fatality Pro - Mic skipping/chopping prob
Hi,
Recently purchased the X-Fi XtremeGamer Fatalty Pro and I'm having a weird issue with the mic. Occasionally the microphone will begin to skip or chop, giving my voice a weird effect. It's usually resolved by changing modes back and forth or doing some random stuff in the sound mixer, although I haven't really found any solid solution. It will come back randomly after a few minutes, or several hours.
I tried the latest drivers, as well as the base drivers included with the cd, and both have the issue. Onboard sound is turned off. Using XP 64. Any ideas?hi i getting same problem but iam on vista 64 u found out a fixx?

On my girlfriend's Zen Xtra 40gb, we have a really odd skipping problem. At seemingly random intervals, the player seems to insert split second sections of other songs into whatever's playing. It's really rather disconcerting. I've tried formatting and updating the firmware, but it's made no difference. Any ideas?
I also have this player and "sometimes" mine has the same problem.
The way i fix this is take out the "skipping" tracks out of "selected music" then put them back in and that will sort the problem. Well it does for me.
thats the only thing i know what to do.
Hope that hel
ps.

3rd Generation iPod - Connection and Skipping/Freezing Probs
Over the last few months I've been having more and more problems. The first was the battery life on the iPod seemed dramatically reduced, whereas a fully charged iPod used to be able to be left in standby over night and still have charge in the morning it now doesn't. The next was connecting my iPod to the PC to only have it give me a Blue Screen of Death, with errors such as pagefault_in_nonpagedarea and mmpoolcorrupteddriver. I went online and checked out many articles in the Apple Knowledge Base and on other Mac Sites. I tried resetting my iPod and putting into disk mode, neither of which work.I also tried reinstalling iTunes 4.9 and using 5.0. I've tried it on another computer which crashed it too. More recently I've also been experiencing my iPod freezing and continuing step the progress bar on screen but no sound is produced. I wasn't initially a fan of Apple however the iPod caused me to change my mind. I thought it would be simple enough to talk to a support center however it was going to cost me £35 to just talk to someone. Can anyone help me or is my iPod just broken? I love the design and I am probably going to buy another one if this is broken.
Note: The HDD also "clicks" and "whirrs" a lot more than usual when playing music
Thanks in advance,
LewisThe first was the battery life on the iPod seemed dramatically reduced, whereas a fully charged iPod used to be able to be left in standby over night and still have charge in the morning it now doesn't.
This is reasonably normal. As iPod's get older, the battery life decreases.
The next was connecting my iPod to the PC to only have it give me a Blue Screen of Death, with errors such as pagefault_in_nonpagedarea and mmpoolcorrupteddriver.
This is a Windows issue only. The iPod is just a hard drive as far as the computer is concerned. It can't cause a blue screen without something being wrong with the computer itself. The "corrupted driver" is a bit of a giveaway too. Reinstalling Windows is probably the only option to fix this sort of thing.
More recently I've also been experiencing my iPod freezing and continuing step the progress bar on screen but no sound is produced.
Now this is more along the lines of a busted iPod. Might look into replacing it or getting it repaired by Apple. -
Using the ACE 4710 for loadbalancing a Sharepoint site.
We currently have a HTTP probe setup to check the port 80 status of the rserver.
Is there anyway to get the HTTP probe to check a DNS entry for each of the application sites? For instance http://info vs http://site are two different web sites running on the same IP. One site could have a problem but the actual port 80 for the IP may be still alive.
Thanks for any information.Has anyone figure this out? I am tring to get healthchecks/probes setup in this same fashion. I have 2 servers with 1 IP but have many sites. I want to probe each side and ensure I get a 200 code. I also have to provide credentials to the site. It seems that if i open IE I can log in just fine to the site with the credentials. However there is an active x control box that is wanting to be installed. When I set this up on my ACE it seems I am getting a http 401 unauthorized error. I have done a wireshark capture while I was browsing and I see the 401 however it also reports a 200 code after that. Do you think this is a problem because of the active x control wanting to be downloaded? Or is this an issue with the first http code that is recieved by the probe, that being the 401 and then the 200? Below is my config (cleaned of course).

okay, i got my ZVM, 2 days ago, and yesterday i put music on it, i thought.. great!! But then when i was listening to some of my songs, some songs just skipped foward to the next song, with me just lying down on my bed listening to it, ie. not moving..
I have tryed The clean dri've thing in the reboot menu, i have updated the firmware, and i have took all the music off, and then on again, TWICE! my sister said that it sometimes happens to her Zen Touch 20GB when she puts masses and masses of muic on at one time, so i tryed only putting a few songs on it, but still it happened, does anybody have any suggestions, it might be my computer, but if it is not, i can still get it replaced, is there anything i can do to fix it's
PLZ help...

Am I missing an argument? I have run debug on LDAP but really don't know what I am looking at...To update the script
==============
Extract the Cisco-supplied LDAP script from the tar.gz or zip file. Rename it to something unique. Update it to use the
new length and offset.
Import the script into the LDAP contexts on both ACEs. Remember, scripts are not replicated and having mismatched scripts will cause replication to fail.
ACE1/ldap# copy tftp: disk0:
Enter source filename[]? UoN-LDAP_PROBE-iLDAP2
Enter the destination filename[]? [UoN-LDAP_PROBE-iLDAP2]
Address of remote host[]? [redacted]
Trying to connect to tftp server......
TFTP get operation was successful
ACE2/ldap# copy tftp: disk0:
Enter source filename[]? UoN-LDAP_PROBE-iLDAP2
Enter the destination filename[]? [UoN-LDAP_PROBE-iLDAP2]
Address of remote host[]? [redacted]
Trying to connect to tftp server......
TFTP get operation was successful
script file 13 UoN-LDAP_PROBE-iLDAP2
If you look at (for example) packet 651 in the capture in wireshark you'll see a
successful bind response. You will need to tell wireshark to decode the packet as LDAP.
The payload is:
30 84 00 00 00 10 02 01 01 61 84 00 00 00 07 0a 01 00 04 00 04 00
You need to have a basic understanding of ASN.1 and something called Basic Encoding Rules (BER) - whicj comes down to TLV format structures.
The key to understanding this output is that there are three ways of specifying a length in ASN.1. The first way we have already seen in the Cisco script is to use a single byte. This known as the "definite" form and can be used for lengths of 127 bytes or less. Otherwise if the high bit is set to one, the low seven bits define the length of length. The length is then encoded in that many bytes. This is the "length of the length field" form. It looks like Microsoft Active Directory uses the indefinite form for all length encoding. The third form (for completeness is "indefinite" where the length is coded as x'80' and the end of the content is marked by x'0000'. Deconstructing the data:
0x30 The start of a universal constructed sequence
0x84 The length of the sequence in "length of the length" format. The next 4 bytes give the length.
0x00000010 sequence length of 16 bytes
0x02 Integer
0x01 The length of the next field (1 byte)
0x01 Value (this is the message ID which agrees with the ID in the BIND Request)
0x61 Application, number 0, use RFC2251 to decode. This is a Bind Response
0x84 The length of the sequence in "length of the length" format. The next 4 bytes give the length.
0x00000007 bind response length of 7 bytes
0x0a Enumeration
0x01 Length 1
0x03 0 - Success
0x04 String
0x00 Length 0 (null string)
0x04 String
0x00 Length 0 (null string)
The patch given takes in 20 bytes from the bitstream,converts it into a hexadecimal string and finds the 6 hexadecimal characters from the 16th byte onwards (Tcl uses zero-based arrays). This is the response code.
Kind Regards

HTTP probe issue with expect regex string
Hello,
We have a simple cgi status page setup to poll a background service and return a "PASS" or "FAIL" as output. I've setup an HTTP probe to look for the "PASS" to determine application health. The issue appears to be that the expect regex is searching the HEADER but not the BODY of the web page. I can successfully match on any string in the header, but never on anything in the body.
Here is what the web page returns if you telnet to it:
HTTP/1.1 200 OK
Date: Thu, 22 Sep 2011 22:45:07 GMT
Server: Apache/2.0.59 HP-UX_Apache-based_Web_Server (Unix) DAV/2
Content-Length: 4
Connection: close
Content-Type: text/plain; charset=iso-8859-1
PASS
Here is my probe:
probe http JOE-TEST-CS
interval 45
passdetect interval 30
receive 30
request method get url /cgi-bin/ERMS-PREP-statusRepo.cgi
expect status 0 999
open 20
expect regex "PASS"
Here is the output of the show probe:
ACE1/euhr-test-ace2# sh probe JOE-TEST-CS detail

If I replace the expect regex "PASS" with anything from the HEADER it succeeds!
Any thoughts?Sorry, I missed it. The content-length in your request is 4. I think this may be the issue. I created a basic HTML page that says PASS in the body and my server is returning a content-length of 224 when I fetch the page. Here is my HTML request:
GET /index.html
http-equiv="Content-Type">
Probe
PASS
Here are my headers that I received:
(Status-Line) HTTP/1.1 200 OK
Content-Length 224
Content-Type text/html

What version of code are you running on your ACE? I can also look to see if there are any known issues.

ACE - TCP probe goes into INVALID state
Hello,
I have a problem with the following configuration of a sticky serverfarm with a backup serverfarm
(this setup is ofcourse used only for failover purposes, not loadbalancing):
probe tcp tcp-8888-probe
port 8888
interval 5
faildetect 2
passdetect interval 3
passdetect count 1
rserver host rsrv1
ip address 10.1.2.10
inservice
rserver host rsrv2
ip address 10.1.2.11
inservice
serverfarm host rfarm-primary
predictor leastconns
probe tcp-8888-probe
rserver rsrv1 8888
inservice
serverfarm host rfarm-backup
predictor leastconns
probe tcp-8888-probe
rserver rsrv2 8888
inservice
sticky http-cookie RFARM-COOKIE sticky-rfarm-1
cookie insert browser-expire
serverfarm rfarm-primary backup rfarm-backup
etc....
The problem is that every time probe state changes (from SUCCESS to FAIL or otherwise), the tcp-8888-probe on the server that changed
the state of service, goes into INVALID state:
#show probe tcp-8888-probe detail
probe : tcp-8888-probe
type : TCP
state : ACTIVE

I have managed to get the probe into FAIL state again for a moment by removing it from serverfarm, and then reapplying, but in a few seconds it goes again from FAIL to INVAILD state, and stays in this state regardless of avaliability of probed TCP port. Only when i'm reapplying it when the port is avaliable/up, it can stay in SUCCESS state, and work till the failure of service, when INVALID state reappears.
What can be the cause of such behavior ?
thanks,
WMHello,
It looks very similar to this bug: CSCsh74871
You may need to collect a #show tech-support and do the following:
-remove the serverfarm in question
-reboot the ace module under a maintenance window.
You may upgrade to a higher version since your version is kind of old.
