Please provide complete, uncut console output.

comment:2 by Carl Eugen Hoyos, 12 years ago

Could you test 9b1f776 ?
It sounds different here, but due to the language barrier I can't say if it is correct or if the bug manifests itself differently with the older version.

sorry, here it is:

I'm not able to find 9b1f776 in: http://ffmpeg.zeranoe.com/builds/win32/static/
On the other hand i faced this when using mplayer2 and report some tickets but it seems to me now it is related to ffmpeg:

please note that the line:
50.04 A-V: 0.000 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0

is not the first one since it is been overridden each time with the new value.

Version:	unspecified → git-master

Can you confirm that the following also allows to reproduce the problem?
$ ffmpeg -ss 50.6 -i 08.rm -t 10 out.wav
(Reports for ffplay are generally only valid if the problem is not reproducible with ffmpeg.)

comment:6 by Abu Abdullah, 12 years ago

yes it reproduces the problem and the output is clearly consisting of a small portion of the beginning of the file:

log file is attached for the output

comment:7 by Carl Eugen Hoyos, 12 years ago

I have attached the result of above command for 9b1f776. Does it sound correct?

comment:8 by Abu Abdullah, 12 years ago

no, it has the same result. There is around 2 seconds from the beginning of the file.

There is very little difference, in version 9b1f776, the unwanted portion start from offset 0 but for the latest version it is just a fraction after the beginning of the file i.e.
9b1f776: 0 -> 2 then seeking point
gf857465: 0.x -> 2 then seeking point

Please check as well the seeking point itself, it seems it is shifted by the same amount i.e.

0 -> 2 then (seeking point+2)

comment:11 by Carl Eugen Hoyos, 12 years ago

Ticket #2232 contains a test-case that is easier to reproduce:

It is working fine now but it gives very tiny ring (or echo) at the beginning.
