@item -sync @var{type}
|

Set the master clock to audio (@code{type=audio}), video
|
|
(@code{type=video}) or external (@code{type=ext}). Default is audio. The
|
|
master clock is used to control audio-video synchronization. Most media
|
|
players use audio as master clock, but in some cases (streaming or high
|
|
quality broadcast) it is necessary to change that. This option is mainly
|
|
used for debugging purposes.

@item -threads @var{count}
|
|
Set the thread count.
|
|
@item -ast @var{audio_stream_number}
|
|
Select the desired audio stream number, counting from 0. The number
|
|
refers to the list of all the input audio streams. If it is greater
|
|
than the number of audio streams minus one, then the last one is
|
|
selected, if it is negative the audio playback is disabled.
|
|
@item -vst @var{video_stream_number}
|
|
Select the desired video stream number, counting from 0. The number
|
|
refers to the list of all the input video streams. If it is greater
|
|
than the number of video streams minus one, then the last one is
|
|
selected, if it is negative the video playback is disabled.
|
|
@item -sst @var{subtitle_stream_number}
|
|
Select the desired subtitle stream number, counting from 0. The number
|
|
refers to the list of all the input subtitle streams. If it is greater
|
|
than the number of subtitle streams minus one, then the last one is
|
|
selected, if it is negative the subtitle rendering is disabled.
