Compile error plugins

[Jan Gruuthuse]

Done test, on same hard disk on sata 300 and sata 600 no difference. So confirm is not disk IO.
I don't use swap disk have 16 GB ram memory. On each used disks have on average 100 GB free.

What I will do later, possibly over the weekend:
Setup a F17 installation within a VM and re-test encoding there.

[mulder77]

OK, I quickly setup F17 and compiled r8175 there.
Looks like performance stays stable there, although the VM layer reduces performance in general.

I really don't know what the difference might be.

One question: In my new installation I only see one option x264. On my regular system there two. Why is that?

[mulder77]

What I stumbled upon is my initial reason for this post.
On my fresh F17 installation I was able to compile r8175 w/o any modification. First I thought that you already fixed the issue in the source code.

But this morning I cleaned my whole (regular) installation to track down the difference. So I removed any bit of previous installations and unpacked a fresh r8175 snapshot.

I reinstalled every package mentioned in the wiki.

Still, my regular installation fails to build the plugins:

-- Build files have been written to: /home/markus/snapshot_8175/buildPluginsCommon
** Failed at make, result in /tmp/logbuildPluginsCommon**

I am not sure if this really reflects my situation with the dropping performance, but I guess I first should fix my installation so the compilation just runs fine.

Any idea what might be wrong so that compiling fails?

[Jan Gruuthuse]

no, not me as I'm only user.
Answer could be if you look in this file /tmp/logbuildPluginsCommon
find *** and probably you should find some error?

regarding dependencies (ubuntu here, so could be other naming convention)
I have these:

[mulder77]

OK, I was able to fix the compile problem.
There were some local libs of xvid installed (from 2007 and 2009) which were used instead the regular libs in /lib64.

After removing them, compiling is now fine.
BTW, I now only have one x264 in the drop down menu, but I built w/o GTK version, so maybe this is why.

But still the performance is poor.

I will keep investigating into the libraries used by the plugins, maybe other crap will show up.

[Jan Gruuthuse]

GTK would only be needed if you use avidemux GTK , Personally I'm only using QT.
Another issue could be videocard? Have you installed opengl for your video card? or VDPAU if nvidia. As I understand it, these would be geared up towards nvidia cards?

[mulder77]

Yes, I am using QT4 only as I experienced the GTK version to be somehow faulty.
No Nvidia card installed, thus no such setting. But I understand it in the way that it's used for local display only, but not for processing the data later.

Currently I do some experiments with an extra physical new installation of F17.

Maybe I will do a fresh start of F17 anyway, as I upgraded all the years starting from Fedore Core 3 or something.

[Jan Gruuthuse]

Not display alone, as you can enable openGl support and select other display option like: XVideo (best). (I could not use opengl display on intel core i5 internal GPU)
Some filters use openGl (OpenGl resize / rotate) and only developers can tell, but QT would use this to if available?

[mulder77]

Another update

I re-installed Fedora 17 to my regular system, busy setting up all services as they have been previously.
I upgraded completely via "yum upgrade".

What I observed now is:
- Initial installation with Kernel 3.3.4 is ok, no performance loss
- Upgraded kernel 3.5.3 (at least) results in the performance loss as I encountered it

Did anybody test and run avidemux 2.6 on a 3.5.x kernel?

[Jan Gruuthuse]

Not by me: ubuntu 12.04 LTS would be good for next 5 years. Current kernel 3.2.0-30-generic (x86_64).

[mulder77]

One more observation.

Reading from my RAID5 device and writing to an RAID10 device is fine on both kernels.

Reading from my RAID5 device and writing to the same RAID5 device will work ok on kernel 3.3.4. On 3.5.3, after aprox. 30 seconds performance will drop. After this initial drop of performance, writing to my RAID10 device will be poor, too.

So I assume something has changed from kernel 3.3 to 3.5, at least as long as the RAID5 device comes into play when writing out the stream.

I will test encoding with mencoder later to verify if the same behaviour occurs there.

For now, I will try to stay on that kernel version, although Fedora doesn't make it easy to keep old stuff.

[mulder77]

One more update:

I tested mencoder with equivalent settings and could observe the same performance breakdown with kernel 3.5.3 and the RAID5 involved.
No such behaviour with kernel 3.3.4.

As expected, it is not directly connected to avidemux then.

I will investigate further into my RAID setup and the changes which came with newer kernel versions.
