|
||
|
|
starts with audio frame \fIcount\fP at the beginning of the AVI-file. If
|
||
|
|
\fIcount\fP is negative, audio is prepended \fIcount\fP padding frames.
|
||
|
|
.TP
|
||
|
|
\fB-a\fP \fItrack\fP
|
||
|
|
Specify the number of the audio channel to shift.
|
||
|
|
.TP
|
||
|
|
\fB-b\fP \fInum\fP
|
||
|
|
Specify if avisync should write an VBR mp3 header into the AVI file. Default is
|
||
|
|
1 because it does not hurt. \fInum\fP is either 1 or 0.
|
||
|
|
.TP
|
||
|
|
\fB-f\fP \fIcommentfile\fP
|
||
|
|
Read AVI tombstone data for header comments from \fIcommentfile\fP. See
|
||
|
|
/docs/avi_comments.txt for a sample.
|
||
|
|
.SH EXAMPLES
|
||
|
|
The command
|
||
|
|
.PP
|
||
|
|
.B avisync -i my_file1.avi -o out.avi -n -10
|
||
|
|
.PP
|
||
|
|
puts 10 audio frames at the beginning of the AVI-file.
|
||
|
|
.PP
|
||
|
|
E.g. if the audio is delayed about 200 ms (0.2 seconds) and you're working with
|
||
|
|
a 25 frames per second AVI-File, you need to shift the audio 200/40 = 5 frames
|
||
|
|
since one frame is 40 ms long.
