Description Albert Zeyer 2006-11-13 14:15:10 UTC
Hi there

I got a few altivec-related errors if I try to compile it (in both 2.6.7-r1 and 2.6.8). In both versions, the errors occurs in: mpeg2dec/libmpeg2/motion_comp_altivec.c

So I replaced this mpeg2dec/libmpeg2/motion_comp_altivec.c and also mpeg2dec/libmpeg2/idct_altivec.c by newer ones (I tried the ones of mpeg2dec-0.4.0b, grabbed here: http://svn.mplayerhq.hu/mplayer?view=rev&revision=12933).

The result is, it compiles fine without problems.

If I start it, I got:

az@ibook ~ % electricsheep
please be patient while the first sheep is downloaded...
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  141 (XVideo)
  Minor opcode of failed request:  19 ()
  Serial number of failed request:  251
  Current serial number in output stream:  251
zsh: terminated  /usr/bin/electricsheep
Comment 2 Albert Zeyer 2006-11-13 14:35:47 UTC
As I have media-libs/libmpeg2 installed, I try to link against it.

So I removed now the complete subdir mpeg2dec of the source and I changed the Makefile.am:
  Remove mpeg2dec from SUBDIRS =>
SUBDIRS = flam3
  Add -lmpeg2 =>
electricsheep_voter_LDADD = @X_LIBS@ -lX11 -lmpeg2 @X_EXTRA_LIBS@

I also had to update the electricsheep-voter.c a little bit:
   Remove bad include-line: #include "mpeg2dec/libvo/vroot.h"

This changes also results in a fine compilation.
Comment 3 Albert Zeyer 2006-11-13 14:55:17 UTC
This time, I got the following:

az@ibook ~ % electricsheep
mpeg2dec_onroot: No such file or directory
zsh: terminated  electricsheep

This should be the result from removing the mpeg2dec-part from the package...

I tried a workaraound:
I created the file /usr/bin/mpeg2dec_onroot with the following content:
#!/bin/bash
echo $@
mpeg2dec -o x11

Now, I got the following:
az@ibook ~ % electricsheep
-f 23 -w -1
mpeg2dec-0.4.0 - by Michel Lespinasse <walken@zoy.org> and Aaron Holtzman
22 frames in 1.68 sec (13.10 fps), 7 last 0.51 sec (13.73 fps)

At least, I see some of the sheeps now.

If I try out other vidoe output modes of mpeg2dec, I got the same X-BadMatch-error in case of xv/xv2 and sdl behavior is very strange, the output is very fast, it seems too fast and very often, the screen got blank and only got a picture back if the window losts the focus and got it back.

Seems not to be perfect, but perhaps, this is libmpeg2-related or a misconfigured Xorg by myself (but everything else is working fine, also Xv (for example used my mplayer)).
I also thin the interaction with the voter-system doesn't work, but this should be fixable.

Perhaps, my first try with mpeg2dec builtin will have better results if I managed this X-BadMatch-error, but this should be manageable. Perhaps, I will take a closer look at the code soon.

Reopen when you've found a viable solution; replacing files by ones from another project is really not one ;)
