@section Advanced options

@table @option

@item -pix_fmt @var{format}

Set pixel format.

@item -stats

Show the stream duration, the codec parameters, the current position in

the stream and the audio/video synchronisation drift.

@item -debug

@item -vismv

@item -rtp_tcp

if you are streaming with the RTSP protocol.

@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.
