Strong variation of the CPU load used by VLC

Hi everybody,

For now, i found the correct combinaison (version of VLC - type of interface - type of streaming - type of protocol) allowing me to stream several synchronised video flux without crashing.
The problem is, on my laptop :
- When i stream 23 video flux, the CPU load used for VLC is 70% 1 min after i started the BROADCAST streaming.
- When i stream 24 video flux, the CPU load is 99% 1 min after i started the BROADCAST streaming.
So what is the problem ? Is the problem coming from me ? Can i correct it by myself ?
It seems there is a kind of runaway of VLC.

Thanks in advance for you answer,
Cordially,
Zi3

Look at the logs to see if there is anything unusual

Thanks for your answer.

If the number of video file is low (6) then the log file is empty.
If it'snt the case (20) then you will find below an exhaustive list of the errors contained in the log file :

- main error: no suitable interface module
- main error: interface "default" initialization failed
- filesystem error: cannot open file C:\Program Files\VideoLAN\VLC\telnet (No such file or directory)
- main error: Votre média d'entrée ne peut être ouvert
- main error: VLC ne peut pas ouvrir « file:///C:/Program%20Files/VideoLAN/VLC/telnet ». Vérifiez les messages pour plus de détails.
- stream_out_rtp: Consider passing --rtsp-host=IP on the command line instead.
- mp4 error: MP4 plugin discarded (no moov,foov,moof box)
- avcodec error: Could not open D:\NTRSCD\Site1\Ex1\9.mp4: Unknown error
- main error: ES_OUT_SET_(GROUP_)PCR is called too late (pts_delay increased to 300 ms)
- main error: ES_OUT_SET_(GROUP_)PCR is called too late (jitter of 5128 ms ignored)
- main error: Timestamp conversion failed for 27213001: no reference clock
- main error: Could not convert timestamps 0, 0 for h264

The most recurrent error is "- main error: ES_OUT_SET_(GROUP_)PCR is called too late (pts_delay increased to 300 ms)"

Do you know the meaning of this error ?

If it tries to open "telnet" then there is something wrong in your command-line.
