Edit: 13.04 is end of life! that's the problem - no support from Ubuntu anymore.

Here are the dates: https://wiki.ubuntu.com/Releases

If it's still single threaded, then the decoding is only single threaded implemented for now in ffmpeg.

I've tried the build and numerous settings but still seeing CPU usage max out at 100%. However, it seems to fluctuate between CPUs instead of balancing across them.

However I'm thinking the settings used to encode the file are causing an issue as 4 out of 5 files play without issue.

Yeah - for software codecs that are single thread only more horsepower helps.

How do we determine if it is multi-threaded or not? The only discussion I found on the bug tracker was about a crash with 1 thread:

Reading the source :-)

I only see 1 thread of dvdplayer with hevc, while there are multiple with h264, so it is single threaded.

Btw. we recently switched to ffmpeg 2.x (thx to wsnipex and fernetmenta). Happy testing and proper HEVC / VC-1 interlaced (sw decoding support).

Hi,

to test it I need the following repos, right?
https://github.com/FernetMenta/xbmc/commits/master
https://github.com/FernetMenta/FFmpeg/co...bmc-master

[fritsch]

No, all in the PPA the first post provides - no need to compile by hand.

But if you really want: The master branch is enough, configure will pull in a supported ffmpeg from fernet's ffmpeg-master branch.

Thanks for the pointer, I've updated to 13.10.

Thanks, but I need to compile the code because the target uses uClibc.

@bkuhls: Oki, make sure to don't use external-ffmpeg and don't use external-libraries. ffmpeg is auto pulled and build and the other libs we ship

Code:

./bootstrap ; ./configure --disable-debug --enable-vaapi --disable-vdpau ; make

is enough. Read the Readme on needed dependencies.

[wsnipex]

@bkuhls: then you have 2 choices:
Mainline xbmc: https://github.com/wsnipex/xbmc/commits/ffmpeg
FernetMenta Master: https://github.com/FernetMenta/xbmc/commits/master

No need to compile ffmpeg extra(unless you cross compile), configure will pull it in automatically

ok, fritsch was faster

[bkuhls]

No need to compile ffmpeg extra(unless you cross compile)

Indeed I need to cross-compile, I am using buildroot for this.
Yesterday a compilation of the repos I mentioned succeeded,
maybe today I will find some time to test the result. I will
keep you informed...

EDIT: A first test still brings a picture with sound on the screen
The sound bug I had several months ago with ffmpeg 2.x did not
reappear: http://forum.xbmc.org/showthread.php?tid...pid1578887

I only see 1 thread of dvdplayer with hevc, while there are multiple with h264, so it is single threaded.

Thanks for checking! Shame it's not. I hope they make it multi-threaded in the future otherwise it's going to painful.

@tutu: Much time for you to learn howto do it and send a succesful PR.

We are all looking forward on you to do this! Thumbs up. Thanks very much in advance.
