Re: SEGMENTATION FAULT bypassed with new issues

[first last-20]

I finally got it going somehow (random buttons/reboots/compiles/slot swaps/etc)

It plays files but I am now having 2 issues.

1) I need to be root as the others don't have permission to write to /dev/em* (I think this is easy to fix for a more permanent solution?) [I did a chown to my username but I think that will reset with a reboot with the way the drivers load?]
2) playback with a avi file just over 4 minutes has sound end at 3 1/2 minutes
single core cpu (file plays normal under non-dxr3 vo)
top set to 0.5sec updates reports 75%id->85%id

I tried some of the options listed but the only thing that did anything was autosync (didn't fix the issue, just didn't have the message pop-up in the normal amount of time)

The exiting was me just quiting as it would have just continued until both audio and video finished.

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
  - Try -ao sdl or use the OSS emulation of ALSA.
  - Experiment with different values for -autosync, 30 is a good start.
- Slow video output
  - Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
  - Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
    e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
  - Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
  - Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
  - Try -nocache.

If you were using a static /dev, the chown should have permanent
effect.
If you are using udev, you should configure it appropriately; look at
the provided em8300-udev.rules file for example.

I have no idea how mplayer works, but it certainly has to recode the
file to MPEG to play it on your H+/DXR3 board, which is much more
CPU-intensive than simply decoding the video. You should consider
transcoding your videos before trying to play them.


Cheers,

Nicolas

BTW, someone using mplayer for playing mkv files on dxr3?

I'm not really successfull. ;-)

Works fine here. What does the log say?

Trying files from http://www.matroska.org/samples/index.html

Using several different mplayer versions, currently the latest:

MPlayer dev-SVN-r26038-4.2.3 (C) 2000-2008 MPlayer Team
CPU: Intel Celeron 2/Pentium III Coppermine,Geyserville (Family: 6, Model: 8, Stepping: 10)
CPUflags:  MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 0

Here are the logs: http://gzp.hu/tmp/mkv/

mkv files plays very bu-uckly, but other formats are OK.

Most likely an mplayer/mkv problem then, although I can't tell anything from the log.
