#2039 new defect

mplayer hangs in fill_audio_out_buffers () after seeking

Description

mplayer stops playback and hangs in a loop (usec_sleep, function fill_audio_out_buffers in line 2142 in mplayer.c) after continually seeking in a mp3 or Ogg/Vorbis? file. I am using the JACK audio output module, though this happens also when using ALSA.

Steps to reproduce:

  1. Start mplayer with any long audiofile (mplayer -ao jack <anyfile>)
  2. Press and hold cursor left key to seek forward
  3. Mplayer freezes after a few dozen seconds at random file positions
  1. Mplayer still responds to SIGINT; has to be given twice to exit (" MPlayer interrupted by signal 2 in module: play_audio").

"2. Press and hold cursor left key to seek forward" should, of course, read "2. Press and hold cursor RIGHT key to seek forward". ;-)

Not reproducible here.
What sound card are you using?
I think it is almost certain this is driver (or at least ALSA) bug which causes your sound card to "hang" after a few reinits or something like that.
I added a abort and error message for this case to make sure you can still exit normally with e.g. q but it won't be able to play audio.
Even my workaround does not work as described above, please tell me, the issue might be slightly different than I thought then and I'll have another look.

comment:3 Changed 7 years ago by bugzilla@…

I am using a RME Hammerfall HDSP Cardbus audio interface in combination with JACK jackdmp SVN HEAD (r4778) and ALSA driver version 1.0.24 (snd_hdsp).

Using MPlayer SVN-r34707 I get only a short hickup, something like "audio got stuck" flashes briefly and then seeking continues, mplayer plays fine. The commit seems to fix it somehow (glitch aside)...

Thanks for debugging on Sunday & greetings from Upper Bavaria! ;-)
