cvs again

Hi,
Thought I might try again to compile cvs to have an mplayer that might 
actually work for me...

vd_ffmpeg.c: In function `init':
vd_ffmpeg.c:160: error: `FF_DEBUG_VIS_MB_TYPE' undeclared (first use in 
this function)
vd_ffmpeg.c:160: error: (Each undeclared identifier is reported only once
vd_ffmpeg.c:160: error: for each function it appears in.)
vd_ffmpeg.c:160: error: `FF_DEBUG_VIS_QP' undeclared (first use in this 
function)
make[1]: *** [vd_ffmpeg.o] Error 1
make[1]: Leaving directory `/home/antt/mplayer/main/libmpcodecs'
make: *** [libmpcodecs/libmpcodecs.a] Error 2

I have no idea what this means - could someone tell me why this has been 
the reason why two attempts at installing from cvs have failed?
Cheers
Antoine

I am a "VIA licenced developer", they gave me the CLE266 source code
CLEXF40040-lite-src_03012004.zip.  Nearly all of the code is Free
Software,  I have put a copy of Free Software without the proprietary
files on my home page (http://jguk.org/data/CLE266_distro.tgz).  These
are the files I wiped because they were not Free Software (I only read
the licence at the top of each file, and not any of whatever was below):

via/include/
debug.h
viampg.h
VidInit.h
VidStruc.h
Vinline.h
vregCME.h

via/Share/Vidcme/
ovlCME.c
ovlfCME.c
ovlfCME.h
vagpCME.c
vdefCME.h
vfcmCME.c

libpostproc and undefined fast_memcpy

Hi !

I'm compiling MPlayer-20040630 (latest cvs snapshot) like this:

./configure --enable-shared-pp
make

...on a P4 box running fedora core 2. It's a single processor, but
hyperthreading is on, so it thinks it's SMP (I'm running the smp
kernel).

Anyway, the point of  --enable-shared-pp is that I'd like to use
libpostproc.so with another package (ffmpeg).

Trouble is, I'm getting an undefined symbol fast_memcpy in
libpostproc.so:

[somlo <at> hedwig MPlayer-20040630]$ objdump -T libavcodec/libpostproc/libpostproc.so | grep fast_memcpy

00000000      D  *UND*  00000000              fast_memcpy

The mplayer binary may very well be using fast_memcpy successfully,
but the libpostproc.so library can't be linked from any other app !

On the other hand, when I compile like this:

./configure --enable-shared-pp --disable-fastmemcpy
make

fast_memcpy goes away, and we get the regular GLIBC memcpy routine:

BUG: MMX code in spp filter induces ringing

When playing with the spp filter recently, I have found that the MMX code
induces ringing.  It does not do so on all sources, only those with sharp
edges, like anime with hard subtitles.  The ringing occurs regardless of
forced qp (even when it's set to 1), in both (hard and soft thresholding)
modes.  It does not occur when using the C version of either mode.

At http://www4.ncsu.edu/~jbcrowso/test.png is a file which contains sharp
edges for testing.  To reproduce this bug, download it and run "mplayer
mf://test.png -vf format=yv12,spp=3:1:0 -vo png" and examine the output. 
Due to the way the spp filter processes parameters, passing an invalid
parameter for the third (mode) option will cause it to stay with the
default of the C hard thresholding code, so you can verify that the C
version operates correctly with "mplayer mf://test.png -vf
format=yv12,spp=3:1:2 -vo png".

[Bug Report] Red and Blue switch with mplayer 1.0_pre4 x11 vo driver

[Information]

While playing a video with the format:

`mplayer -vo x11 movie.avi`

I notice that the blue and red channels appear to switch.  All other 
video drivers seem to not have this issue.  I've been told that it was 
not an issue in mplayer 0.92.

I've tried the cvs build from ~2 days ago, but still get the error.  
Didn't notice a thread about it in the -dev-eng or -users mailing list 
archive.

[Recreation]

1) install mplayer 1.0 pre4
2) play a media file with -vo x11 driver

[Expected results]

The file plays normally

[Actual results]

The red and blue channels of the video appear to be switched.

Thank you in advance for any help.

Sincerely,
(Continue reading)

Lucky you. :-)

So. That's the "lite-src" i.e. the source code freely available that is
missing the mpeg decoder interface... which was the whole point of the reverse
engineering effort. This was achieved and the functionality is now provided by
the unichrome project as as open source driver.

However, this is simply providing the source code for the interface to the chip.
The piece that is missing and that requires work is to write a plugin for
mplayer that then interfaces to the driver. Which I believe was the original
question.

Regards,
Ivor.

I had the same problem a long time ago (sometime before 0.90). My solution was 
to use the "rgb2bgr" video filter.

I think the option I used was "-vf rgb2bgr". This swaps the red and blue 
channels. Check the man page if it doesn't work; its been a while since I 
used it.

If its only certain movies that give you trouble, try creating a file "<Movie 
Name>.conf" in your ~/.mplayer/ directory, and add the line above. This will 
load the filter every time you play the movie(s).

Arrggh!
There was obviously a heinous nasty in the latest stable release that 
made streaming media choke in a few different ways. The cvs fixed it, or 
did until I uninstalled it, installed the stable (to make sure that it 
wasn't a gentoo build error as opposed to an mplayer error), and then 
reinstalled the cvs - first the same cvs, then the absolute latest (30 
mins ago). F^\{!!!
