I've run into a brick wall. I'm trying to finish up kf5 but can't get
kdenlive to work. Trying to trace it, I looked at the dependencies.
The mlt package installs an executable named melt. This program plays an
mp4 file. The one I use for testing is
http://anduin.linuxfromscratch.org/~bdubbs/files/big_buck_bunny.mp4
It is a 1 minute video/audio file for testing.
It plays fine with ffplay, vlc, and mplayer. In a previous version of
BLFS,
SVN-20150703, it also plays fine with melt.
The problem with the latest version is that I get:
$ melt big_buck_bunny.mp4
[producer avformat] big_buck_bunny.mp4
VDPAU failed to initialize decoder
(An invalid/unsupported VdpDecoderProfile value was supplied.)
[h264 @ 0x1eee2c0] Could not find an AVHWAccel for the pixel format:
vdpau_h264 Assertion choices[n] != AV_PIX_FMT_NONE
failed at libavcodec/utils.c:1258
Aborted
I've tried rebuilding mlt and its dependencies as well as ffmpeg, x264,
libva and libvdpau. I also tried reverting from mlt-0.9.8 to mlt-0.9.6.
Can I please get someone to build/test melt (package mlt) for me and
see if
it works for you.
I can't test it for the moment, but does vdpau actually work for
you ? I normally use xine to check that - on most of my boxen it
moans (if run from a term) if vdpau is not available - and neither
my SandyBridge, my Phenom, nor my Haswell have workign vdpau so I
stopped building it on them.
The Aruba used to have working vdpau (that mobo died), the Kaveri
does - I'm on the Kaveri, but no qt5 in this build and I'm
struggling to get libreoffice to build after turning off SSLv2.
xine plays the file fine, but I do get some messages:
$ xine big_buck_bunny.mp4
This is xine (X11 gui) - a free video player v0.99.9.

I'm not sure about the hardware support messages. This is a nvida card
(GeForce 210) on my -dev system. Wouldn't x264 give h264 support?
Armin gave me some links and I installed some nvidia firmware. Now melt
works and the this hardware doesn't support messages above are gone.
