<br><i><strong>Low-Latency Live Video Streaming over Low-Capacity Networks</strong><br>
Giovanni Gualdi; Rita Cucchiara; Andrea Prati<br>
Multimedia, 2006. ISMapos;06. Eighth IEEE International Symposium on<br>
Volume , Issue , Dec. 2006 Page(s):449 - 456<br>
Digital Object Identifier 10.1109/ISM.2006.102<br><strong>Summary:</strong>This
paper presents an effective system for streaming over low-capacity
networks (such as GPRS and EGPRS) of live videos with low latency.
Existing solutions are either too complex or not suitable to our scope.
For this reason, we developed a complete, ready-to-use streaming system
based on H.264/AVC codec and UDP/IP stack. The system employs adaptive
controls to achieve the best tradeoff between low latency and good
video fluency, by keeping the UDP buffer occupancy at the decoder side
between two given levels. Our experiments demonstrate that this system
is able to transmit live videos at CIF format and 10 fps over
GPRS/EGPRS with very low latency (1.73 sec on average, basically due to
the network delay), good fluency and average quality, measured with
PSNR, of 31 dB on GPRS at 23 kbps at 10 fps</i>
<br><br>So I wonder if it can be possible to reproduce this using VLC ? or Has anyone of you already tried to stream video on such bandwidth ? (yes some area in the world are still using GPRS for the moment :( ).<br>

We (AmericaFree.TV) stream 3GPPx video at 96 and 160 Kbps using QTSS.<br>
This is MPEG-4 + AAC.<br>
<br>
The quality is pretty decent at 160 Kbps.<br>

Even h264 codec ?<br>

You want video over a variable (20 - 50) kilo bit link ?<br>
<br>
That's as slow, or slower, than dial up.<br>
<br>
I may be wrong, but there is no codec that I am aware of that provides any kind of quality over such a narrow link.<br>
<br>

Hello,<br>
<br>
I would like to ask you about the possibility to stream video over GPRS.<br>
I made some test and the bandwidth I have can reach 50 kbit/sec, let's say<br>
20 kbit/sec (average).<br>
<br>
Do you know if it is possible to stream video encoded with VLC using this<br>
bandwidth (GPRS connection on mobile)?<br>
<br>
If yes what do you advise to use?<br>
- last VLC version 1.0.4 ?<br>
- codec video: X264 ?<br>
- codec audio: AAC ?<br>
- fps ? , audio bitrate & video bitrate<br>
- encapsulation: ?<br>
- protocole: HTTP ? (slow) maybe UDP is better or RTP/RTSP?<br>
<br>
If some of you has ever experimented this and can give me some clues?<br>
<br>
Regards,<br>
<br>
