delphi, indy10 tcp audio streaming

Question

i am trying to make an application that use video/audio streaming through TCP connection, i already done the video streaming with indy10 component(idtcpserver and idtcpclient), is it possible do the same thing but with audio?

Answer 1

Sure.

TCP is just data channel. It is totally agnostic to what kind of data is transferred to it. HTML pages, programs, video, audio - whatever. It is just a data channel within TCP protocol.

However, "streaming" usually means "near to real time". If some frames of video or audio did not arrived during few seconds - they better be skipped and forgotten and newer music or video be played. You would not want your Skype conversation suddenly stuck for a minute and then playback all that minute to you, just because of few seconds network jam. You'd better loose a word or two and then either recover by context or ask the correspondent to repeat. Thus TCP with built-in retransmissions and usually not very large buffers is not a perfect choice for multimedia streaming. Usually UDP + application-implemented integrity control is better choice for it.

I believe you need to use the unit VFW. With avistream, you join video + sound in a compressed stream.
