Description
In recent mplayer releases pressing "." intermittently works as expected, mplayer shows frame by frame.
The problem arises when you hit and leave this key pressed - older versions of mplayer then start playing media at its normal speed. However in this mode ("." is pressed and not released) recent mplayer releases start playing media at arbitrarily high speeds, even more audio and video streams totally lose synchronization.

could you paste mplayer output when this problem occurs? frame stepping still works for most people.
curious what audio output you use ?

22 seconds of audio de-synchronization just for 7 seconds of video )) That's insane.
And like I said, I can reproduce this bug on any video I have here.

are you using pulseaudio on your system at all ?
and does -mc 10 or -mc 0 change anything?

PulseAudio is not installed here at all, just plain ALSA, Linux kernel 3.3.1.
-mc 10

Nothing at all, none of these options help.
Running with -v -v -v doesn't reveal anything interesting either, I see :
demux_lavf_fill_buffer()
vd_ffmpeg data ...
32768=mp_read(), pos: ..., eof:0
no errors, warning or anything of that kind.
comment:10 by , 12 years ago
If with -v and ALSA you do not get this message:
alsa-pause: pause supported by hardware
That is where your problem lies. If you get that message, almost certainly the ALSA driver is broken.
Either way it shouldn't be related to MPlayer.
If you are absolutely certain that it is a regression in MPlayer (and not e.g. in ALSA) please find out the exact revision when it broken.
However there haven't been any relevant changes to the the ALSA ao since years, so it seems very unlikely.
And yes it works perfectly for me, never more than 0.1 s out of sync, both with -ao alsa and -ao pulse.
comment:11 by , 12 years ago
only thing that may have changed was switching to lavf demuxer for mp4 format
does using the mplayer demuxer
aka -demuxer mov or -demuxer mkv (for mp4/mkv respectively)
help any?

I will try to file a bug report about this problem, however it seems kinda weird to me that the support from hardware is required for this feature to work properly.
Either way it shouldn't be related to MPlayer.
If you are absolutely certain that it is a regression in MPlayer (and not
e.g. in ALSA) please find out the exact revision when it broken.
I don't use this feature too often so the perceived breakage/regression could coincide with the hardware refresh I had a year ago.
However there haven't been any relevant changes to the the ALSA ao since
years, so it seems very unlikely.
And yes it works perfectly for me, never more than 0.1 s out of sync, both
with -ao alsa and -ao pulse.
Feel free to close this bug report as WONTFIX/INVALID then if you are sure about hardware pause support and its absolute necessity.

No, it cannot/doesn't help because it happens on all sources (mkv, mov, avi, mpg, etc).

-ao oss has fixed this issue for me, however I need to stop all other applications accessing audio to avoid "[AO OSS] audio_setup: Can't open audio device /dev/dsp: Device or resource busy".
Weirdly with -v -v -v -ao oss I also see *no* messages about hardware pause support.

Maybe it's because with oss mplayer uses IOCTLs.
comment:15 by , 12 years ago
oss doesn't print the message either way because
1) Only -ao alsa ever prints it
2) -ao oss does not use hardware pause support, mostly because that is not possible via OSS.
Now as -ao oss shows hardware pause support is not necessary, however with even the crappiest onboard sound generally supporting it, nobody thought it necessary to implement the same hack as for OSS (also there is a risk it might not work anyway).
I'd be curious to know what kind of audio hardware that is that has this issue.
Without access to hardware with such behaviour fixing it is also a little bit risky I guess.

I have a very common Realtek ALC892 Audio Codec which can be found on a large number of Asus P8* motherboards.

Hm, I realize I have been using HDMI-out, so no idea whether the real hardware has the same issue.
Anyway I found a way to test this, so I added the workaround that OSS uses (in r34842).
However with proper pause support you'd really hear the audio matching each frame when frame-stepping, with this workaround you'll generally hear only silence.

Takashi Iwai:
"The driver supports the pause operation already. If you are using dmix, it
doesn't because of the dmix plugin."
and then about lack of support for "hardware" pause in dmix and if it's fixable:
"Well, this isn't trivial, unfortunately, although it's not impossible. The
pause will need to rewind the already-buffered samples at the current point,
then applies them at continue. So, it needs a lot of code."
So, mplayer relies on something that's not available on most Linux systems (dmix is now universally employed, not sure about PulseAudio).
"." is utterly broken - even when you watch something frame by frame (by pressing and releasing the key after getting a frame) audio gets out of sync almost immediately.
