Mplayer will not run and crashes with audio output set to jack with bio2jack-0.7 installed. Reproducible: Always Steps to Reproduce: 1.bio2jack-0.7 installed 2.set mplayer audio output to jack 3.attempt to play video Actual Results: MPlayer interrupted by signal 11 in module: ao2_init - MPlayer crashed by bad usage of CPU/FPU/RAM. Expected Results: should run fine downgrading to bio2jack-0.4 allows mplayer to work
I also created ebuilds for versions 0.5 and 0.6 (not in portage) and discovered that bio2jack-0.6 causes mplayer to crash as well while 0.5 seems to be OK.
Can you provide a backtrace? I just tried with bio2jack 0.7 (but compiled myself under debian), and it works (although there are some bugs with 1 channel and 8 bit audio). Maybe I should mention that I didn't install the libbio2jack.so* files though, only the static .a lib...
Not sure of my gdb skills but I get this: Program received signal SIGSEGV, Segmentation fault.

>Maybe I should mention that I didn't install the libbio2jack.so* files though, only the static .a lib... I created an overlay ebuild adding a "shared" use flag and built only the static lib, had to remerge mplayer but the crash was identical. As a side note, xmms-jack, which uses bio2jack works fine.
The gdb output is okay, but it doesn't show any line number for the crash in libbio2jack... At least the stack seems to be corrupted: rate_hz=-1215051172 etc. If you want you can try valgrind, but I'm not certain it will help much further (if you do, make sure you use an audio-only file, too much output otherwise). Anyway, I saw that 0.7 has quite a few bugs, one of them making MPlayer hang on low-quality audio (e.g. mono). They have been fixed in libbio2jack cvs, but it now depends on libsamplerate with its really slow conversions :-((

Line 1618 is 'client_name = 0;' where client_name is a global char *. I'm not sure why this would cause any kind of segfault given that its the exact same code called from xmms-jack. I wonder if it has anything to do with how the library is being loaded by mplayer but I'm not sure how to debug the issue since I don't see it here with any other apps that use bio2jack. Reimar, "and it works (although there are some bugs with 1 channel and 8 bit audio). Maybe I should mention that I didn't install the libbio2jack.so* files though, only the static .a lib..." You mention issues with 1 channel and 8 bit audio. These issues haven't been reported on the bio2jack sf page so I wasn't even aware that they existed. Have you tried with cvs bio2jack? It should correctly handle these cases. If not I can try to get some media that has these audio settings and try to reproduce under mplayer. Chris
@Chris Morgan Read my comment again *g* : "They have been fixed in libbio2jack cvs, but it now depends on libsamplerate with its really slow conversions :-((" It was caused by a broken JACK_GetBytesFreeSpace implementation (the value returned was bigger than the actual buffer size, so MPlayer would hang forever trying to push that amount of data in the buffer) P.S.: This bug could be caused my a myriad of reasons, I can't really tell without being able to reproduce, but since the stack is quite obviously corrupted, valgrind should be most helpful..
Yes, I'm mixing two things together ;-) Chris, can you run things under valgrind to see if that produces any more useful output? As far as libsamplerate goes I thought the conversion functions are well optimized. How do you know that the slowness of this library is affecting you? Are you seeing a major increase in cpu usage? You can call void JACK_SetSampleRateConversionFunction(int converter) to use a less cpu intensive encoder. Chris
As a note this isn't a "one off", someone else has posted to the Gentoo forum with the same problem. Valgrind, hmmm...have to figure out how to use that one.

I guess I should either backport the new jack ao or prepare an mplayer snapshot.

Would be nice to get the new ao_jack some testing *g* To Chris concerning libsamplerate (sorry, somehow missed that part): As far as I can tell it is floating-point only - that can get very slow on some architectures/CPUs (not to mention the extreme opinions on it by some MPlayer developers *g*). Would be interesting to see some real comparisons against our lavcresample though (quality and speed wise). Also the int/floating point conversion have been a bit unreliable in MPlayer - though last time I checked bio2jack only supported int input anyway.

The addition of the libsamplerate support was a huge gain for bio2jack in terms of flexibility. For most people using a floating point conversion library shouldn't be an issue but I would welcome patches to add support for libraries that did fixed point sample rate conversion because as you've mentioned it would improve performance on some architectures. I'm not sure what the issue with int/floating point conversion has been with mplayer, can you clarify? Bio2jack only supports int input because it is intended to act as an interface layer between alsa/oss/arts and jack and afaik none of those systems support floating point samples. Chris
Still a bug in newer versions? Thanks all
