#3235 new defect
ffmpeg doesn't respond to most signals on debian sid when using pulse input

Description
ffmpeg doesn't respond to SIGINT on debian sid when using a -f pulse input device.
Trying to send SIGINT through Ctrl+C or through kill -2 {pid} has no response. Stopping with q still works.
Running under valgrind ffmpeg does respond to sigint.
Removing any of the configure flags will cause the bug to dissapear (Except libpulse and prefix which are required to test it in the first place)
./configure --enable-libopencv --enable-libpulse --prefix=/home/j/FFmpeg --enable-gnutls --shlibdir=/usr/lib/x86_64-linux-gnu
Note about the output below. There are warning lines like so:
avutil configuration: [...]
But these lines disappear when configured with --libdir=/usr/lib/x86_64-linux-gnu though the bug persists so I've cut them out of the output to make it more readable.
How to reproduce:
git clone git@github.com:FFmpeg/FFmpeg.git
cd FFmpeg
./configure --enable-libopencv --enable-libpulse --prefix=/home/j/FFmpeg --enable-gnutls --shlibdir=/usr/lib/x86_64-linux-gnu
make
make install

Removing any of the options in that configure line makes the bug disappear, so that's as simple as I can make it.
The following is the simplest line that removes the library warning but retains the bug:
./configure --enable-libopencv --enable-libpulse --enable-gnutls --shlibdir=/usr/lib/x86_64-linux-gnu --libdir=/usr/lib/x86_64-linux-gnu --enable-shared --disable-static --prefix=$HOME/FFmpeg

Are you sure that the problem disappears if you remove the --prefix option from configure?
comment:4 by , 11 years ago
No, that's just there to stop make install messing with my system binaries (On that note, if you know a better way I'd love it)
comment:5 by , 11 years ago
As said, I never install to avoid this issue. I suggest doing the same when reporting bugs / simplifying a report.
I still cannot reproduce with your exact configure line:

To simplify the command line, could you test the following?
$ ffmpeg -f pulse -i default -f null -
follow-up: 7 comment:6 by , 11 years ago
Your command still shows the bug - I think it's specific to debian sid.
Since shlibdir is required for the bug to show I have to compile and install the libraries if I don't want the version mismatch warnings to pop up.
Is there a way to compile the binary statically? I tried the following but got an error:
$ ./configure --enable-libopencv --enable-libpulse --enable-gnutls --shlibdir=/usr/lib/x86_64-linux-gnu --disable-shared --enable-static --extra-libs=-static --extra-cflags=--static ERROR: gnutls not found
That would help eliminate environment as a potential cause

Replying to jnvsor:

Why is that needed?
I may misunderstand, but are you missing the following to avoid installing a shared FFmpeg?
$ export LD_LIBRARY_PATH=libavutil/:libavcodec/:libavformat/:libavdevice/:libswscale/:libavfilter/:libswresample/
comment:8 by , 11 years ago
I wish I knew - if I remove
--enable libopencv --enable-gnutlsor--shlibdir=/usr/lib/x86_64-linux-gnuthe bug disappears.
$ export LD_LIBRARY_PATH=libavutil/:libavcodec/:libavformat/:libavdevice/:libswscale/:libavfilter/:libswresample/ $ ./configure --enable-libopencv --enable-libpulse --enable-gnutls --shlibdir=/usr/lib/x86_64-linux-gnu --disable-shared --enable-static --extra-libs=-static --extra-cflags=--static ERROR: gnutls not found If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.log" produced by configure as this will help solving the problem.
Actually now that I think of it - libopencv and gnutls aren't being compiled from ffmpeg are they? The problem is probably caused in the versions in the debian sid repos.

Edit: libopencv just had an update ->

But still here

$ export LD_LIBRARY_PATH=libavutil/:libavcodec/:libavformat/:libavdevice/:libswscale/:libavfilter/:libswresample/ $ ./configure ...
I was actually thinking of the following (to test):
$ ./configure --enable-shared $ make ffmpeg $ export LD_LIBRARY_PATH=libavutil/:libavcodec/:libavformat/:libavdevice/:libswscale/:libavfilter/:libswresample/ $ ./ffmpeg
comment:10 by , 11 years ago
Your LD.. line got the bug reproduced without the shlibdir option:
$ ./configure --enable-libopencv --enable-libpulse --enable-gnutls --enable-shared
$ make ffmpeg
$ export LD_LIBRARY_PATH=libavutil/:libavcodec/:libavformat/:libavdevice/:libswscale/:libavfilter/:libswresample/

comment:11 by , 11 years ago
Just to make sure:
The problem is only reproducible with pulse input, not with anything else?
The problem is only reproducible with shared FFmpeg, not with --disable-shared --enable-static?
The problem is not reproducible if you don't enable libopencv?
The problem is not reproducible if you don't enable gnutls?
comment:12 by , 11 years ago
I've tried various input devices (x11grab, pulse, alsa, files of various codecs) and pulse is the only one that causes the issue (That I know of)
It did happen with --enable-static --disable-shared but as the shared libraries weren't compiled I got the warning:
configuration: --enable-libopencv --enable-libpulse --enable-gnutls --enable-static --disable-shared WARNING: library configuration mismatch avutil configuration: --enable-libopencv --enable-libpulse --enable-gnutls --enable-shared avcodec configuration: --enable-libopencv --enable-libpulse --enable-gnutls --enable-shared avformat configuration: --enable-libopencv --enable-libpulse --enable-gnutls --enable-shared avdevice configuration: --enable-libopencv --enable-libpulse --enable-gnutls --enable-shared avfilter configuration: --enable-libopencv --enable-libpulse --enable-gnutls --enable-shared swscale configuration: --enable-libopencv --enable-libpulse --enable-gnutls --enable-shared swresample configuration: --enable-libopencv --enable-libpulse --enable-gnutls --enable-shared
It was not reproducible if I removed libopencv or gnutls but now I can't compile if I remove either so I can't confirm (same error with either):
$ make ffmpeg LD libavcodec/libavcodec.so.55 /usr/bin/ld: libavcodec/mqc.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC libavcodec/mqc.o: error adding symbols: Bad value collect2: error: ld returned 1 exit status make: *** [libavcodec/libavcodec.so.55] Error 1
comment:13 by , 11 years ago
Please always run make distclean before rebuilding, that fixes both the issue with static building and with the incorrect compilation of mqc.o
comment:14 by , 11 years ago
I can now confirm it does not occur if I omit either --enable-libopencv or --enable-gnutls (Sorry for needing all the hand-holding)
follow-up: 17 comment:16 by , 11 years ago
Nope - I get the library config mismatch warnings but the bug persists.
comment:17 by , 11 years ago
Replying to jnvsor:
Nope - I get the library config mismatch warnings but the bug persists.
This indicates that something went completely wrong at compilation time. Please test the following (in my opinion it is relevant to confirm that this has nothing to do with shared compilation):
$ make distclean $ ./configure --enable-libopencv --enable-libpulse --enable-gnutls $ make ffmpeg $ ./ffmpeg -f pulse -i default -f null -
This should not show any library warnings (if it does, something else is broken), does it allow to reproduce the problem?
Which versions of opencv, gnutls (and pulse) are you using?

| Summary: | ffmpeg doesn't respond to SIGINT on debian sid when using pulse input → ffmpeg doesn't respond to most signals on debian sid when using pulse input |
|---|
Well I'm an idiot, I should have checked more than just sigint.
Of the first 20 signals, 9 terminates the program and 19 puts it into background (where it can be restarted with $ fg) but there is no response to any of the other signals. (IE: Ctrl + Z won't put it into the background)
The next signal it responds to after 19 is 34, and from there on ffmpeg exits with "Real time signal #"
The weird thing is that while 17 19 and 23 are supposed to be sigstop ffmpeg only responds to 19. Afterwards it responds to sigcont when passed as 18, not as 19 or 25.
Replying to jnvsor:
This actually makes a bug report invalid if you are not specifically reporting an incompatibility. In that case, the exact output would be essential.
I cannot reproduce your problem on Opensuse, could you test with a simpler configure line, preferably the same I used (you don't have to install FFmpeg to test)?
