Downloads in Chunks

(http://stream-recorder.com/forum/showthread.php?t=14546)

hi,

i wanted to know if it is possible to make rtmpdump download data from the flash media server in larger chunks?

for instance, I observed while the file is being downloaded, the client downloads small chunks of data from the server, then pauses and resumes again.

this is how the output looks like:

Code:

is there a way to speed this up so that the my complete internet bandwidth is utilized?

As I understand from this wiki page of RTMP:

http://wiki.multimedia.cx/index.php?title=RTMP

each packet is transmitted in chunks and it is possible for the client to increase the chunk size.

2 questions:

1. is it possible to change the chunk size in rtmpdump?
2. will increasing the chunk size help in accelerating the download from flash media server and help me in utilizing the full bandwidth?

thanks :)

1. No.
2. No.

To be more specific
(1) the server chooses its chunksize. The client chooses its own chunksize too, but that obviously is irrelevant here since the client is downloading.
(2) the server controls how fast it transmits data.
