No Errors But No Video #53

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. I followed all insturctions
2. dshowserver test outputs correctly
3. mplayer svn patches nicely (using patch from other recent issue)
4. mplayer builds nicely. 
5. mplayer from CLI runs with what look like happy output but I get sound
and NO VIDEO..

What is the expected output? What do you see instead?
If i run
 mplayer -demuxer lavf -vc coreserve -vo xv -fs working.mkv 
on a short (5 second) 720p test video i download i get a squak of sound the
screen flashes and then instantly its over..  Here is my output from that.

PCLinuxOS 2007
Coreavc 1.7.0
mplayer latest svn for the last 10 days

I have a mplayer build wich I created on 08-08-2008 from svn with CoreAVC 
included
and this one works.
I also got no errors but playing an 1080 move with my build from 08-08-2008 my
processor usage is from start 25-30%, first 2 minutes tested. With the latest 
svn and
CoreAVC the processor usage go to 100% from starting on one core.

My system is:
Core2Quad 6600 with 2 GB Mem on Gigabyte GA-p35-DS3R mainboard.

Today, I compiled mplayer again from svn.

When I run: mplayer <filename> -demuxer mkv it works fine. But without the 
demuxer
option on the commandline, mplayer used lavf default.
Maybe someone know how to fix this, and let mplayer choose mkv default.

I've solved the problem (for me) and created a patch. This is what I changed:

--- libmpdemux/demux_lavf.c     2008-09-04 22:48:50.000000000 +0200

I've added a complete dshowserver.patch wich included this patch.

I will not apply any patches that modify any portion of mplayer other than
vd_dshowserver.c

This specific issue is dut to yet another demuxer incompatibility.  as always, 
the
way to try to get things to work with CoreAVC is to try all possible demuxers 
and
hope for the best
