Video stuttering in compiled player application

[Antony007]

Hi,

I am compiling dcpomatic from sources in Ubuntu 18.04 by following the steps mentioned here https://dcpomatic.com/build/linux?distro=ubuntu-18.04

I observed that the video is stuttering in the dcpomatic2_player. Whereas if I download the deb file from the website, it works fine.

So are there any difference in build parameters mentioned in the above link and build parameters used for the pre-built binary provided by the website.

:)

Thanks, Antony

Strange. Did you build with my patched version of OpenJPEG?

[Antony007]

Yes. as mentioned in the link, "libopenjpeg version 2.1 with some patches"

[cth103]

Maybe you could post up the output of

ldd /usr/bin/dcpomatic2_player ldd /usr/local/bin/dcpomatic2_player

assuming that's where you have installed your self-built copy...?

OK thanks, nothing glaring there. When you say "stuttering", is DCP-o-matic reporting dropped frames?

[Antony007]

Yes. a lot of dropped frames are reported and is also visible on screen

[Antony007]

One thing I did follow not in the link was "git checkout v1.6.x" for libdcp. I was getting errors while building, so I saw the this issue and followed that.

And also I observed that binary downloaded from the website is statically linked to couple of libraries and If following the compilation guide we end up with dynamic linkage. Although not likely, but still does this have to do anything ?

[cth103]

You're right about the libdcp branch. I can't imagine static/dynamic linking would have much of an effect.

Is the CPU maxed out when you are seeing the dropped frames?

[Antony007]

CPU usage is around 40 - 45%.

[cth103]

That's odd. Can you see how many threads DCP-o-matic is starting?

[Antony007]

When application is started, the thread count is 20 and during playback thread count is 21

[Antony007]

Static linkage didn't do any good

You could try building with my docker image, if you like. They're all here now:

https://hub.docker.com/repository/docker/cth103/dcpomatic

Once you have installed the ubuntu-18.04-64 one you should be able to get cdist from

https://github.com/cth103/cdist

Then make a ~/.config/cdist file like

git_prefix git://git.carlh.net/git

and you should be able to build a .deb with cdist -p dcpomatic -t ubuntu-18.04-64. It would be interesting to see if that works ok.

Hi, Thanks for taking the time. Unfortunately I would not be able to test it immediately. But will revert back soon with the results.

Thanks :)
