VLC 0.8.4 - http streaming dropping frame

[toffee73100]

Hello,

I’m using vlc 0.8.4 on windows and I have some problems to see my video via HTTP from a another computer.
I must use HTTP due to firewall restriction.

I use this command line on the computer 1 to launch streaming server:
vlc -vvvv c:\video\ep3.mov --ttl 12 --loop --sout "#transcode{vcodec=mp4v,vb=256}:standard{access=http,mux=asf,url=127.0.0.1:8084/video}" --noaudio -I rc

When I launch VLC media player on the computer 1, I can see the video.
But when I try to use from a another PC (on internet), I receive these messages:

ffmpeg error: more than 5 seconds of late video -> dropping frame (computer too slow ?)
main warning: late picture skipped (5663821)
main warning: late picture skipped (5862785)

...

...
ffmpeg error: more than 5 seconds of late video -> dropping frame (computer too slow ?)

and I cannot see the video

Configuration: PC1 Intel P4 2.4G 512 Mo XP SP2

Someone could help me?

Thank you in advanced for your help.

Hello,

After some investigations, I have a low bandwidth (upload: 128k…).
Do you know some parameters/optimizations to stream video even if you have a low bandwidth (or use VLC with an another tool) ?

Many thanks for your help

Bandwidth is a major issue. It sounds like the bitrate/codec you are using maybe Too High for your upload speed.

Questions:

Are you attempting to stream over the net or on a LAN?

Can you use UDP as opposed to HTTP?

What Bitrate/Encapsulation/Codecs are you using?

If you are trying to do Audio & Video via 128Kbps you are going to have problem remember you are going to want AT LEAST 64Kbps Audio and AT LEAST 128Kbps Video and Upload speeds are not Guaranteed unless you are on ISDN or have an agreement with your ISP. ETC.

Thanks for your answer.
I must stream over internet, and due to firewall restriction, I must use the port 8080.
I have on this computer Apache with proxy mod (port 8080), tomcat (port : 8081) and VLC (port 8082). I use Apache as proxy server to redirect user request on VLC or tomcat.
I need only video so I deactivate audio.
I use this command:
vlc -vvvv c:\video\ep3.mov --loop --sout "#transcode{vcodec=H263,vb=60,fps=10,samplerate=40000,height=288,width=352}:standard{access=mmsh,mux=asfh,url=127.0.0.1:8084/video}" --no-sout-audio -I rc

I tried mmsh or HTTP access. After some tests, Mmsh is better than http.
I tried video codec H263, MPEG4V,WMV1/2 …
I tried mux: TS, ASF, ASFH …
I tried vb between 60 and 100. With vb>70, 2 users cannot see the video…
I want to decrease the number of frame, but it does not work (ftps=10): I have this error message:
[00010279] stream_out_transcode private debug: drift is too high, resetting master sync
