hi,
Thanks for your kind reply, I studied about MediaRecorder to capture video,
but i want to send video to my server (TCP socket) live. and save this video on
a file.
also i found that, the ParcelFileDescriptor.fromSocket(socket) can be use to
send the video but i don't know, how to recieve it on server side. if you have
any idea about please reply
me.
Thanks and Regards.
