Set the master clock to audio (@code{type=audio}), video

|
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.
