MPlayer interrupted by signal 4 in module: decode_video

Hello, My svn MPlayer crushed with the following debugger message: Signal received(SIGILL) in Thread mplayer at mplayer-checkout-2007-06-01/libavcodec/armv4l/simple_idct_armv6.S:288 illegal instruction.

[PATCH] Allow to use live555 with other compilers than /usr/bin/g++

[PATCH] cpu detection for core2
by Loren Merritt 08 Jun '07

08 Jun '07

The configure code to detect core2 in 64bit mode was different from 32bit mode, and didn't work on my core2. This changes it to be the same as 32-bit mode, which works. Also, -march=k8 is faster than -march=nocona when run on a core2. Or should it be -mtune=k8 with no -march, to avoid amd-specific instructions? -march=k8 works for me, but that doesn't mean it's theoretically correct. (Of course -march=core2 is the most appropriate, but that's only in gcc >=4.2) --Loren Merritt

[PATCH] support for mov yuv2 fourcc
by Reimar Döffinger 07 Jun '07

07 Jun '07

Hello, yuv2 seems to be some format similar to yuy2 but with unsigned chrome (very weird). Attached patch makes it play (sample at http://samples.mplayerhq.hu/mov/yuv2.mov) Does it look okay? Greetings, Reimar Döffinger

tr seems to be used incorrectly in the vidix check in configure. Attached patch fixes my problem (untranslated lowercases). If no one objects I'll commit it tomorrow. Nico

I checked linker flags (LD) in our toolchain configuration , and saw that everything is correct. I'm attached here several files, could you please check this files, and let me know if there is something not configured correctly. In current version (svn) , there was a dependency from mplayer on live555 package, this created a compilation problem. I saw a fix ( http://osdir.com/ml/video.mplayer.cygwin/2007-01/msg00036.html <http://osdir.com/ml/video.mplayer.cygwin/2007-01/msg00036.html> ) in Google, that suggested to remove the "--with-livelibdir=DIR" from configure, and add instead , --with-extraincdir=DIR & --with-extralibdir=DIR (both points to $(HOST_CROSS_LIB_DIR)/live , and remove "--enable-live" from Makefile (Makefile from workspace-nokia770_layer-dist-mplayer). I applied this changes and got this link error. Please let me know if some other info you might needed. P.S. Sorry if this gets reposted, I had previously attached my configure & configure.log but the message was too large. Thanks, Alex

add -Wall to default CFLAGS
by Diego Biurrun 07 Jun '07

07 Jun '07

I propose adding -Wall (back) into the set of default CFLAGS. I think it was removed by an icc patch ages ago. Having those extra warnings cannot hurt, on the contrary, hopefully some more warnings will get fixed. Opinions? Objections? Diego

audio video sync
by Vinod Madhav Joshi 07 Jun '07

07 Jun '07

Hi all, I am not sure whether is this right place for my query. But please help me at least tell me which mailing list in mplayer i have to join. My question is- streaming servers streams MPEG -2 program streams as seperate audio and video elementary streams. On client side after receiving these streams how to sync audio and video. PTS values are not available. whether RTP timestamps should be used if yes then how. Thank you.
