Hi list,
I am trying to work around a problem that I have not experienced in the
past (but I can not trace it down to a specific package upgrade):
mplayer and mpv both crash when playing back audio files of varying
formats (wav, ogg, etc) which have a different sampling rate than jack
(tried with both jackd1 and jackd2). The files play fine when using alsa
as audio output driver.
A gdb backtrace points to usr/lib/x86_64-linux-gnu/libswresample.so.3
which is from Debian's package libswresample3 of version
7:4.3.5-0+deb11u1
I can not downgrade this package to the only other available version
(7:4.1.9-0+deb10u1) without removing most of my audio programs.
Is this error known? How can I find out more about it, and how could I
possibly fix it?
Thank you!
Peter

Maybe an upgrade is in order, Peter? I don't know what other audio
applications depend on it.

I don't have the same problem, either, but my
Debian 11 setup here lists
these versions of that library:

libswresample3/stable,stable-security 7:4.3.5-0+deb11u1 amd64
Thanks, this is funny, I have bullseye and bullseye-updates in my
sources.list and get only
$ apt list -ia libswresample3
libswresample3/stable,stable-security,now 7:4.3.5-0+deb11u1 amd64 [installed]
libswresample3/oldstable 7:4.1.9-0+deb10u1 amd64
This corresponds to the following search
https://packages.debian.org/search?keywords=libswresample3&searchon=nam…
Mine's using the 4.4.3, not 4.3.5.
David, do
you have any additional entries in your sources list that will point
to this 4.4.3?
Thanks!

Fine, the same version I am running.

Ok, ran more tests:
mplayer crashing over jackd running 44.1kHz with a 48kHz wav file.
or
mplayer crashing over jackd running 48kHz with a 44.1kHz wav file,
posting in verbose -v mode:
Building audio filter chain for 44100Hz/1ch/s16le -> 48000Hz/2ch/floatle...
[libaf] Adding filter lavcresample
[SWR @ 0x7f64bde4a9a0]Using s16p internally between filters
So mplayer crashes when resampling different rates but not bitdepths.
mpv in turn segfaults over jackd running 44.1kHz or 48kHz with both, a 48kHz and
a 44.1kHz wav file of 16bits depth.
mpv posts the following message when run with the --v verbose flag:
[swresample] 48000Hz mono s16 -> 48000Hz mono floatp
So it uses libswresample for changing the bitdepth and subsequently
segfaults.
Happy to hear about any more ideas!
I hope I will find the time soon to run a debug with symbols of
mplayer, as explained in the segfault error message:
MPlayer interrupted by signal 11 in module: af_init
- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in
DOCS/HTML/en/bugreports_what.html#bugreports_crash.
[ This binary of MPlayer in Debian is currently compiled with
'--enable-debug'; the debugging symbols are in the package
'mplayer-dbgsym'.]
Wish you luck. Let me know if there are any more tests
I can run for you.
Thanks Roger! Will let you know, this is very appreciated!

Self-resolving issues are the best kind. Also the worst as one may never
find out what happened. Hope it behaves itself in future.
BTW @david - having DMO sources active has been known to cause
incompatibilities with standard Debian packages. It is generally
recommended not to do this.
Even the libdvdcss package is not necessary to obtain directly from DMO
these days, the Debian libdvd-pkg package will fetch and install it.

I have the libdvd-pkg package installed. What version of the library
does it fetch? Just tried reinstalling it, and my libdvdcss2 version is
unchanged from the DMO version, 1.4.3-dmo1. The libdvd-pkg package
itself says it's version 1.4.2-1-1.
I also have the 1.4.3-dev files installed. Does libdvd-pkg install
those, too?
For what it's worth, the libswresample 4.4.3 is from DMO and works fine
here.
What Debian 11 doesn't offer me is newer versions of some multimedia
applications I use, such as avidmux, Handbrake, K3b, and Kdenlive.
Although I see there are some version overlaps between DMO and
bullseye-backports, but not enough to make eliminating DMO an option for me.
Debian has also been uncooperative with another application I use,
Rosegarden. Debian 11 insists that the current version I have compiled
and installed from source (v22.12) needs to be "upgraded" to the version
in the repository (v20.12, two releases behind). Sorry, not acceptable.
Finally, in the past (on different systems) I've run combinations of
stable, sid and experimental - so having only Debian and DMO is an
improvement. :)
Personally, IMO, these kinds of gyrations about mixing repositories
wouldn't be necessary if Debian made the effort to keep up with
application versions.
Ideas?

I never actually install Rosegarden. I compile it from source, and run it
in-situ. Debian (devuan in my case) never gets a look-in.
