[Howto] MPlayer with CoreAVC

[quvil]

When I tried to test whether codec registration had worked (dshowserver -c CoreAVCDecoder.ax -s 1280x720 ...), dshowserver crashed with an assertion:

No id specified, assuming test mode
Opening device
dshowserver: malloc.c:3074: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.
Aborted

Did somebody encounter something similar?

I compiled dshowserver statically according to the instructions on a system with Atom n280 running Karmic, and tried to use it on a 64 bit system with Core 2 Duo T7250 running Jaunty.

P.S.: site hosting a tarball with precompiled binaries was unavailable, I could not check whether it would behave differently.

Hi, I got exactly the same crash, using 32bit system also running karmic

Indeed there is a problem with compiling dshowserver on Karmic and using it on Jaunty: I tried to compile on some old 32 bit Red Hat, and it worked. Maybe the problem is in gcc version (4.4.1 on Karmic).

Hi there!
I did the tutorial and everything looked well.
I'm running a Ubuntu Karmic machine, and used
the CoreAVC with jaunty before without any problems.
But now I have audio and the video window, but now
video
This is the mplayer output without audio:
