[CentOS] why gstreamer can't use ffmpeg on centos?

[qw]

Hi,

I have one question about gstreamer. Why gstreamer can't use ffmpeg on centos? 
is there some patent issue related to ffmpeg and gstreamer?

Thanks!

Ok, then at that point, I like Valery's suggestion. Try looking at

No. I'm saying it's only happened once since I installed C7, not long
after it was released. While I haven't kept records of dates and times,
I don't think it was at any specific time.

I saw it 2 or 3 times previously, probably some Fedora version,... my
tired old brain won't divulge that info right now.

It seems reasonable that it's some kind of hardware issue but I don't
see anything in the logs I've thought to check.

I inquired, hoping some of you could suggest other places to look for
info, in retrospect.

thanks for the suggestion!

but I kinda doubt that's it, this has been highly rare, and doesn't do it when
e.g. I'm at work and leave it on all day.

Hi,

you can add the rule and then run "service iptables save" - it will
save the current rules in /etc/sysconfig/iptables

when you run "iptables" or "iptables -S", it prints only the filter
chain by default. Try "iptables-save" - it prints all rules. The other
option is "iptables -t nat -L -n" or "iptables -t nat -S"

Hope it helps.

I recently had the opposite problem.  I'd comback to a laptop
I knew I had turned off and it was up and running.

Turns out the bios had a setting to automatically power up
at 1:30 AM.  Perhaps your bios has a "shut down at ..."

Accidents happen.  I didn't intentionally mail you off-list, and when I

..which isn't relevant to the question of what you consider "evidence" 
of security practice implications.


Look, go to https://www.google.com/ right now and tell me what you see.  
Do you suddenly distrust the internet's single largest domain?  Do you 
think they implement poor security practices?



For someone who wants "evidence" you make a lot of unsupported
assertions.  You do see the irony, don't you?

The difference is that I state this is my opinion and I do not claim
it as a fact.  Your statement claimed a factual basis.  I was
naturally curious to see what evidence supported your claim.


Citation required.

Allow me an example.  To quote you:
"The usual way a private key gets compromised is by theft or by 
tampering with its generation.  Putting yourself on a hamster wheel of 
constant certificate generation and distribution simply increases the 
opportunities for key theft and tampering."


Now, when you asked "what possible benefit accrues from changing secured 
device keys on a frequent basis?" I pointed you to letsencrypt's 
documentation, which describes the benefits of 90-day certificates.


So, please describe how I am "claiming a factual basis" while you are not.


Automated security is BS.  It has always been BS and it always will be
BS.  That is my OPINION.  It may not be a fact for I lack empirical
evidence to support it.  However, it has long been my observation that
when people place excessive trust in automation they are are
eventually and inevitably betrayed by it.  Often at enormous cost.


This is what I consider "enormous cost":
https://en.wikipedia.org/wiki/Heartbleed#Certificate_renewal_and_revocation

After a major security bug which exposed private keys, hundreds of 
thousands of servers did not take the required action to secure their 
services, and the vast majority of those that took *some* action did it 
incorrectly and did not resolve the problem.


Had those sites been using letsencrypt and renewing automatically, the 
exposed keys would have been replaced within 90 days (typically 60 max, 
so 30 days on average).  Instead, it is likely that the problem will 
remain a risk for "months, if not years, to come."


And that's empirical evidence, which you have yet to offer.


This impediment however is strictly an artefact of signing code with
short term certificates.  I simply had to reset the date on my MB back
to some future date when the certificate was valid and everything
worked fine.


Apple's intermediate certs have a 10 year lifetime.  If you consider 
that "short term" then I fear that nothing is suitable in your opinion.



But hey, what is my time worth in comparison to the security those
certificates provided?  SECURITY that was trivially evaded in the end.


Fixing your clock is not "evading" security.


Exactly what mindless person or committee of bike-shedders decided
that software should be distributed so that copies of it expire?


Expiration is a fundamental aspect of x509 certificates.  Do you 
understand x509 at all?

I might have missed the beginning of this thread: when the screen goes
black can you still ssh to the machine (you may need to enable ssh, and
switch from DHCP to static IP for this test). If you can ssh, this will
mean kernel is still happily running, if not, then kernel might have
panicked. I would do what Mark suggests: clean it to avoid overheating
(but don't do it yet, until you pinpoint the place where it fails). BIOS
turns the machine off completely when temperature threshold is tripped, so
tripping temperature sensor threshold is not your case as your screen
backlight is still on. However, overheating video chip may do what you
see. And it also may open some micro crack. I also would do the following:
attach external screen, make them both ON, and see if only internal panel
goes black or both of them do.

Tell us what your experiments reveal.

As I said, I am in favor of having the plugin installed by default.  However, 
making it a dependency of yum is not the only way to do that.  It could be 
moved into the Base package set.  Then someone who doesn’t want it can remove

I know, and we put infants on no-fly lists for essentially the same
religious beliefs.  The benefit of so-called general security for the
rest of us who do not have to bear its individual specific cost.  The
is no evidence that this sort of stuff works. It is just done so that
if anything bad happens the authorities can claim that they did
something preventative which they can point to. Regardless of how
ineffectual it was.

Automated security is BS.  It has always been BS and it always will be
BS.  That is my OPINION.  It may not be a fact for I lack empirical
evidence to support it.  However, it has long been my observation that
when people place excessive trust in automation they are are
eventually and inevitably betrayed by it.  Often at enormous cost.

Let me give you an example of stupidity in action with respect to
signed certificates.  I have a MacBookPro c. early 2009.  There have
been five or six major releases of OSX since then.  Being a cautious
type I download the upgrade installer apps and archive them before
installing and upgrading.

Over this past weekend my MB stopped booting.  It would get to the
Apple symbol and go black.  Much trial, error, and research later I
discover that this is sometimes occurs when a MB has been repeatedly
upgraded and that a clean install is the recommended cure.  Oh,
by-the-way, if you ever have to do this then do not use the Apple
Migration Assistant app when you are done.  You will be sorry.

So, I get out my archived Installer app, go to install it and BANG! My
MB proclaims that "Somebody has tampered with the application or it is
corrupted!". OH NO!

This impediment however is strictly an artefact of signing code with
short term certificates.  I simply had to reset the date on my MB back
to some future date when the certificate was valid and everything
worked fine.  Of course this took me a great deal of frustrating
effort to discover what had happened to all of my archived copies and
how to fix it.  In the middle of a system recovery I might add.

But hey, what is my time worth in comparison to the security those
certificates provided?  SECURITY that was trivially evaded in the end.
 Exactly what mindless person or committee of bike-shedders decided
that software should be distributed so that copies of it expire?  What
security issue was addressed by this decision? What benefit to the
public was achieved?

When real people suffer real inconvenience and real loss of productive
effort because of mindless adhesion to bromide based

Have you checked the PSU? Maybe vacuum it out (or open up the back of the

Hi,

  I think that should be for the container pipeline itself, not atomic
registry. Correct me if I am wrong.
Also, I should probably consider requesting write access to the container
pipeline page as well at
some point.

oh, sorry, I did try that, but failed to mention it. No, it makes

I'm not suggesting its a centos problem, I'm just looking for advice

[CentOS] bad iscsi performance after upgrade to CentOS 7.2

[Ulrich Leodolter]

hi all,

after i upgraded a physical server (SUN FIRE X4170) from CentOS 6.8 to 7.2
i am not able to get the same iSCSI read performance.

the server is connected to HP P2000 Storage via 2 x 1GbE Ethernet.

CentOS 6.8 gives me full read performance on raw iSCSI devices /dev/sdxx at 
115MB/s.
CentOS 7.2 allows only 90-100MB/s, read performance varies and is not stable 
like for 6.8

the multipath performance on 7.2 is even worse.

CentOS 6.8 allows to read a full speed and stable 220MB/s.
CentOS 7.2 maximum was 140MB/s after i disabled readahead for multipath devices 
in tuned.

btw. i tried many recommended optimizations in 7.2, but i am not getting the 
raw iSCSI read
performance than on 6.8,  and on 6.8 i had no special tuning für iSCSI.

mtu 9000 is set and verified for both OS, other settings like network buffers 
are almost identical.

has anyone an idea why iSCSI read performance degraded in CentOS 7.2 ?

best regards
ulrich
