I didn't add that part to the book because it really doesn't apply to us.
We install a recent Mesa and kernel. The more important part is really
at the VideoAcceleration link.
I didn't have a problem with mplayer, just the mlt package, but I note
that my ~/.mplayer/gui.conf did not get updated with a new mplayer install.

Works fine with mplayer-SVN-r37794 (notice that ffmpeg is newer than 3.0.
{ time mplayer big_buck_bunny.mp4; } 2>&1 | tee
big_buck_bunny.mp4-mplayer.log
Could not get language to change to C above.
For VLC, needed to choose VA-API via DRM.

big_buck_bunny.mp4-vlc.log
My general impression is that mplayer was better (sound and video).

[blfs-dev] Video problems
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. -- Bruce -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
