Power on, let PTP stabilize (might take a few minutes), start recording on each Raspberry Pi. Step2: Align frames. ... Original Raspberry Pi raspivid, source code: https: ...
It can also lock to another PTP source and generate video and time code sync for a local facility to synchronize across the network. PTP Redundancy A PTP system can be implemented with two or more grand masters, using the Best Master Clock Algorithm (BMCA) that ensures another source can assume the active role if the current source fails.
Several Linux distributions provide a package for Linux PTP. This section discusses how to get Linuxptp source, build, and install the tools. git clone http://git.code.sf.net/p/linuxptp/code linuxptp cd linuxptp/ make sudo make install. By default, Linux PTP artifacts are installed into /usr/local/sbin/.
PTP/IEEE-1588-2008 (Version 2). Default profile. GPS reference clock accuracy is better than 30 nanoseconds RMS to UTC(USNO). PTP timestamp resolution is 8 nanoseconds. Up to 128 PTP sync packets per second. Dual-gigabit network ports, each configurable to provide PTP packets.

IEEE1588 PTP, delay mechanisms of reciprocity, request delay mechanism V1, V2. IEEE 1588-2008 program source IEEE1588 PTP Protocol, this code implements two mechanisms: request for delay mechanisms, reciprocal delay mechanisms, reference implementation of transparent transmission clock, support both version V1, V2....
Getting the Code. You can download the latest released version at Source Forge. http://sourceforge.net/projects/linuxptp/files/latest/download. The source code is managed using the git version control system. To get your own copy of the project sources, use the following command. git clone git://git.code.sf.net/p/linuxptp/code linuxptp
2 days ago · The linuxptp package includes the ptp4l and phc2sys programs for clock synchronization. The ptp4l program implements the PTP boundary clock and ordinary clock. With hardware time stamping, it is used to synchronize the PTP hardware clock to the master clock, and with software time stamping it synchronizes the system clock to the master clock.
