Hi,
I do see multiple questions related to media/audio clock recovery/synchronization as well as very detailed explanation for same but did not find any mention of video clock synchronization. I do understand video playback is lot more related to platform i.e. overall decoder and render-er buffer depth and outside the scope of AVB specification. Having said this, video synchronization (across multiple listeners) as well as audio/video lip-sync is one of the main use case of AVB hence this must have been explained or discussed some where.
My understanding is video framework is typically dependent on system time whereas Vysnc clock is used at driver level. Does this mean system time must be synchronized to PTP time if one needs to achieve synchronized video playback because AVTP presentation time is typically derived from PTP time in AVB?
