Android Question UDP sync

[Ang3ls]

hi, can you give me some advice on the possibility of controlling the playback of some videos on different devices ...
I have some videos on various devices (Android TV BOX) and I would like to be a central software via a UDP command start a video in sync into all Devices...

i have read in internet that i need to use udp datagram to make the video sync frame by frame

but i don't know how start to write this kind of application... if you have any advice for start to writer code ...

i'm waiting your ideas ;°)

If -udp-master is given, MPlayer sends a datagram to -udp-ip (default: 127.0.0.1) on -udp-port (default: 23867) just before playing each frame. The datagram indicates the master's position in the file. If -udp-slave is given, MPlayer listens on -udp-ip/-udp-port and matches the master's position. Setting -udp-ip to the master's broadcast address allows multiple slaves having the same broadcast address to sync to the master. Note that this feature assumes an ethernet-like low-latency network connection. Your mileage may vary on high latency networks.

i have found this into mplayer manual... is possible to recreate this method in b4a ?

You can send a UDP packet (datagram) to that port with the Network library.

i know the network library but i use this for udp communication ... it's possible to use also for video sync ?

You can send UDP packets. I'm not familiar with the specific requirements of video syncing.
