SIGSEGV with ffwmv3 @ ppc
by Marco Graf 25 Aug '05

25 Aug '05

Hi there, I got a SIGSEGV. I throw it through gdb. following the corresponding data. It's on a PowerPC running debian. Think it should be the video codec ([ffwmv3] vfm:ffmpeg (FFmpeg M$ WMV3/WMV9)). Problem is the same with xv, x11, dga and aa video-output. I'm sorry but I don't have the time at the moment to check with the verry new cvs version (it's cvs from 22.8.2005). /proc/cpuinfo: processor : 0 cpu : 740/750 temperature : 67-69 C (uncalibrated) clock : 291MHz revision : 2.2 (pvr 0008 0202) bogomips : 581.63 machine : PowerBook motherboard : AAPL,PowerBook1998 MacRISC detected as : 50 (PowerBook Wallstreet) pmac flags : 00000009 L2 cache : 1024K unified pipelined-syncro-burst memory : 128MB pmac-generation : OldWorld Debian testing mplayer code from: cvs 22.8.2005 uname -a: Linux powermga 2.6.11-mga #8 Tue Apr 19 14:55:08 CEST 2005 ppc GNU/Linux gcc -v: Reading specs from /usr/lib/gcc-lib/powerpc-linux/3.3.5/specs Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,pascal,objc,ada --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-gxx-include-dir=/usr/include/c++/3.3 --enable-shared --enable-__cxa_atexit --with-system-zlib --enable-nls --without-included-gettext --enable-clocale=gnu --enable-debug --enable-java-gc=boehm --enable-java-awt=xlib --enable-objc-gc --disable-multilib powerpc-linux Thread model: posix gcc version 3.3.5 (Debian 1:3.3.5-13) ld -v: GNU ld version 2.15 as --version: GNU assembler 2.15 Copyright 2002 Free Software Foundation, Inc.

bitstream codec version information not passed on with mencoder?
by compn 24 Aug '05

24 Aug '05

this was a user in #mplayer who had this problem: I've transcoded a show from a NTSC DVD to a 512x384 xvid file (max_bframes=1:nogmc:noqpel), but I can't play it back on my standalone DVD player. opening the video with avidemux2 and then saving it again (copy/copy) makes the files playable on that player. a friend tells me it's because of the lack of tags on the original video, which are present in the file output by avidemux2: "inside data / metadata there should be [USER] XviD0039 or XviD0038" Thomson DTH8045 it's a DVD-Recorder <skamp-> I'm using mplayer CVS from 2005/08/13 and xvid 1.1.0 beta 2 for encoding <skamp-> avidemux2 v. 2.0.42 (http://avidemux.berlios.de/) http://xmm.sourceforge.net/DivX5-6_Xvid_Bitstream_version.php lists the bitstream codec version, does any of this get into mencoder? can it?

-ffourcc and -of lavf
by compn 15 Aug '05

15 Aug '05

a user came to #mplayer wanting to combine some wmvs, so i tested it... mencoder 1.wmv 2.wmv -oac copy -ovc copy -of lavf -o done.wmv which worked, but changed the fourcc from MP43 to DIV3 i tried -ffourcc MP43 but i dont think the asf muxer can handle this fourcc? -ffourcc WMV3 changes the fourcc (but WMV3 cant decode MP43...) i guess what i'm saying is that the asf muxer needs to accept MP43 fourcc and that all fourcc's accepted in all the muxers need to be documented and that -of lavf needs more docs and examples! -compn

Hi I was having problems with some audiosoftware not loading correctly some pcm dumps made with mplayer, for example with matlab, fixing this makes those program who use this field happy, and more compliant with specs, hope you apply, thanks.
