speed up scheduling a little bit by reversing chunk ID order

the change should not modify scheduler behaviour

git-svn-id: https://repository.napa-wine.eu/svn/napawine-software/trunk/Applications/OfferStreamer@1715 c54fac2e-1815-407e-9b96-088d06743913

e9397abf 07/25/2010 08:26 PM Csaba Kiraly

fix: measurement of initial chunk losses

since the chunkbuffer was initialized with the first chunk at its
head, some losses were added counted right at start-up

README


This is DumbStreamer, the dumb streamer!
As such, do not expect it to be smart...

Here is a quick'n'dirty, informal, description about how to compile
and test the thing (do not expect to find any information about what
the dumb streamer is, or how it works. If you need such information,
please drop me an email - ):

Ok, here we go...
- To download the DumbStreamer
git clone http://www.disi.unitn.it/~abeni/PublicGits/DumbStreamer.git
- To compile it:
cd DumbStreamer
make prepare
make
You can type "make FFDIR=<path to an ffmpeg build>" to compile a version
of the streamer with a minimal libav-based input module.
You can type "make DEBUG=WhyNot" to compile a "debug" version of the
dumb streamer (prints out a lot of crap and debug information, not really
useful in practice unless you are trying to hunt a bug).
You can type "make THREADS=YesPlease" to compile the multi-thread version
of the streamer. Not tested with libav*.
You can type "make GRAPES=<path to your grapes>" to use a different build
of GRAPES
- To test it:
First, I suggest to test the non-libav-based version. It generates
"fake" text chunks, which are useful for debugging
1) build as above (make prepare; make)
2) start a source: ./dumbstreamer -I lo
3) in a different shell, start a client: ./dumbstreamer -I lo -P 5555 -i 127.0.0.1 -p 6666
4) start another client: ./dumbstreamer -I lo -P 5556 -i 127.0.0.1 -p 6666
5) ...
Explanation: "-P <port>" is the local port used by the client (6666 by
default). Since I am testing source and multiple clients on the same
machine, every client has to use a different port number. "-i <IP addr>"
is the source IP, and "-p <port>" is the port number used by the source.
After this testing, I suggest recompiling with debug on, and with threads.
Test as above, and enjoy.
- To see something interesting:
You have to build a libav-based version:
1) cd /tmp; svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
2) cd ffmpeg; ./configure; make -j 3; cd ..
3) git clone http://www.disi.unitn.it/~abeni/PublicGits/DumbStreamer.git
4) cd DumbStreamer; make prepare; make FFDIR=/tmp/ffmpeg
Now, prepare a (video-only) input file:
5) /tmp/ffmpeg -i <whatever.avi> -r 25 -an -vcodec mpeg4 -f m4v test.m4v
6) The input currently needs to be called "input.mpg", so
ln -s test.m4v input.mpg
Start the source. For the moment, you need to manually specify the rate
(will be fixed in the future):
7) ./dumbstreamer -I lo -t 40 -c 50
create a FIFO for the output, and attach a player to it:
8) mkfifo out; ffplay out
start a client:
9) ./dumbstreamer -I lo -P 5555 -p 6666 -i 127.0.0.1 > out
- Enjoy... ;-)

A lot of cleanup is needed, and the input module is still far from being
reasonable (but this is not our business ;-)
But you can now enjoy some video...

Remember! The DumbStreamer is dumb! Peers try to send chunks to the source...
Scheduling is blind...
All of this is very bandwidth inefficient. If you want to start more clients,
please increase the upload bandwidth of the source (dumbstreamer -t 40 -c 200,
or even more...).

Enjoy your streaming,
Luca
