Thanks for your reply :-) I didn't know that the mailing list is not that
active.
About Input file:
---------------------------------------------------------------------------------------------------------------------------
cadlab:/srv/streaming # tcprobe -i Blood_Diamond.avi
[tcprobe] RIFF data, AVI video
[tcprobe] summary for Blood_Diamond.avi, (*) = not default, 0 = not detected
import frame size: -g 720x416 [720x576] (*)
frame rate: -f 25.000 [25.000] frc=3
audio track: -a 0 [0] -e 48000,0,2 [48000,16,2] -n 0x55 [0x2000]
(*)
bitrate=122
kbps
length: 206153 frames, frame_time=40 msec,
duration=2:17:26.119
-------------------------------------------------------------------------------------------------------------------------
So, As I told you, I want lots of constant bit rate streams (starting from
1 Mbps to 100 Mbps, 5000 was just an example to test, but it doesn't seem
to produce constant bit rate, that's why I posted. )
I used "-R 0" because man page says
-R n[,f1[,f2]]
0 Constant bitrate (CBR) encoding. [default]
The codec tries to achieve constant bitrate output. This
means, each encoded frame is mostly the same size. This type of encoding
can help in maintaining constant filling of hardware buffer on set top
players or smooth streaming over networks. By the way, Constant bitrate is
often obtained sacrifying quality during high motion scenes.
"-o test" indicates the output file name, right? That I have already
included.
So, basically I want to upscale the video (by padding bits or stuff like
that) and I want to stream over the network. I don't care about the output
file format, it could be any format which the other computer (client) can
play, and no worries about the quality as well. If there is something I am
misinterpreting, please let me know, I would like to clarify as well.
