Unable to use input.pulseaudio #489

Closed kiklop74 closed 7 years ago

kiklop74 commented 7 years ago

I am trying to use input.pulseadio as source from which to store audio files. The script I have so far looks like this:

extinput = input.pulseaudio(
      id="yeah"
    , device="alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo"
    , clock_safe=false
    )

output.file(
    %flac,
    "/some/dir/audio/%Y-%m-%d/%Y-%m-%d-%H_%M_%S.flac",
    reopen_when={0m0s},
    mksafe(extinput)
)

And it just goes through script without saying anything or sometimes I get core dump. The device id is correct. I tried doing the same with sox like this:

sox -t pulseaudio "alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo" recording.wav silence 1 0.1 5% 1 1.0 5%

And it works just fine.

Ubuntu 64bit 17.04, unity, pulseaudio etc. liquidsoap 1.32 with all needed plugins.

Hi,

I'm able to play here using pulseaudio on OSX with a specific device.

Is your device listed in:

pacmd list-sinks

?

Do you have more logs to share?

Yes here is the pacmd output:

So it seems to be only working when sox binary is configured. Is that expected?

This script always fails with core dump

set("log.file.path","/tmp/basic-audiostore2.log")

extinput = input.pulseaudio(
      id="yeah"
    , device="alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo"
    , clock_safe=false
    )

# Dump the stream
output.file(
    %flac,
    "/home/darko/audio/%Y-%m-%d/%Y-%m-%d-%H_%M_%S.flac",
    reopen_when={0m0s},
    mksafe(extinput)
)

While this one works

set("log.file.path","/tmp/basic-audiostore2.log")
set("protocol.say.sox_path","/usr/bin/sox")

extinput = input.pulseaudio(
      id="yeah"
    , device="alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo"
    , clock_safe=false
    )

# Dump the stream
output.file(
    %flac,
    "/home/darko/audio/%Y-%m-%d/%Y-%m-%d-%H_%M_%S.flac",
    reopen_when={0m0s},
    mksafe(extinput)
)
toots commented 7 years ago

Interesting. The difference you noticed is probably just a side effect of the segfault. Sometimes when the code is run slightly differently it doesn't trigger the conditions for the crash.

Have you confirmed that this is not an issue with the output part? What happen if you replace output.file by a output.dummy ?

kiklop74 commented 7 years ago

With dummy it works just fine in both cases. How can I debug this? My knowledge of liquidsoap is less than rudimentary.

kiklop74 commented 7 years ago

Interesting this version just works

set("log.file.path","/tmp/basic-audiostore2.log")

extinput = input.pulseaudio(
      id="yeah"
    , device="alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo"
    , clock_safe=true
    )

# Dump the stream
output.file(
    %flac,
    "/home/darko/audio/%Y-%m-%d/%Y-%m-%d-%H_%M_%S.flac",
    reopen_when={0m0s},
    mksafe(extinput)
)

It seems that clock_safe must be true.

kiklop74 commented 7 years ago

And now I started it again and got core dump. Restarted again and it works... so there is something wrong but not sure how to debug this...

toots commented 7 years ago

Yeah, it's a segfault. Have you ever used gdb? This is the tool to find out. Let me see.. Try something like this (from memory):

gdb /path/to/liquidsoap/bin
> run /path/to/script
(crashes)
> thread apply all bt

See if you can get a backtrace of the segfault..

toots commented 7 years ago

Some more doc here: https://wiki.debian.org/HowToGetABacktrace

kiklop74 commented 7 years ago

Ok here is what i got so far:

This is the cli I ran:

gdb -q --command=/home/darko/projects/consulting/audio-test/bt.gdb /home/darko/.opam/system/bin/liquidsoap

bt.gdb is just a command file to simplify the process and it looks like this:

run  /home/darko/projects/consulting/audio-test/sample-audioin.liq
thread apply all bt

And here is the backtrace:

toots commented 7 years ago

Well, it's a mess.. gdb points to printf but, honestly, it can't be that call. I'm suspecting a whole stack corruption here.. I'm gonna review the pulseaudio binding code. You did this a dummy output right?

kiklop74 commented 7 years ago

No. This backtrace is made using the output.file. When I use output.dummy nothing crashes.

If you need me to do something else please let me know.

kiklop74 commented 7 years ago

New data for you. If I try to use mp3 as output format everything works perfectly. Only with flac there are coredumps (and yes I do have installed flac support).

toots commented 7 years ago

Ha! Then it's definitely flac. That code is hacky, I'll try to revisit it.

toots commented 7 years ago

Ok, there was an easy one that has a good chance of being your issue. Any chance you could try with the latest flac? Try this:

git clone --recursive https://github.com/savonet/ocaml-flac.git
cd ocaml-flac
opam pin add flac .

Thanks. I just pushed another small fix to ocaml-flac, mind doing a git pull there and then opam reinstall flac ? Thanks!

kiklop74 commented 7 years ago

Now it works. Thanks for your effort :) When can we expect new release of flac package?

toots commented 7 years ago

Awesome! I'll release it right now.
