The VideoLAN Forums

Hi,
i am trying to add libvlc to Zoneminder-Viewer https://github.com/skuda/ZoneMinder-Viewer that it's using motion jpeg itself right now, i would like to completely replace the internal streamer and use libvlc to stream x264 if asked for, when i am on lan i have an extra delay using libvlc that i don't have using mjpeg directly.

I have tried to disable cache using "--network-caching=0" argument to libvlc_new() but still i get an extra 2~3 seconds, the argument it's working because if i put 5000ms value i get 5 seconds more of delay. It is possible to disable caching completely? would be useful when i can be sure i am on LAN.

Other question, my complete arguments right now it's {"--no-video-title-show", "--network-caching=0"}, the documentation says that i should not use this way to pass parameters because i have no warranty that it will work on older or newer releases, do i have any other way to get this result? Thanks!

Regards,
Miguel Angel.

If you are streaming, there are other internal buffers, I think.

this internal buffers can be controlled from libvlc or they are static?

i assume they are static, ok, i will maintain old mjpeg code for lan usage, thanks.

THey can be controlled.

some tip for search the documentation please? i can't find anything about this internal buffers.

Use the preferences box of VLC to search for caching and you will see the sout-mux-caching

I am not sure but --clock-jitter=0 might also be related to that.

Hello, I also need to disable caching in vlc. Has anybody solved this?

I use VLC for playing of live FLV/HTTP stream and need to reduce the latency.
I've found such comment in src/input/stream.c:

/* Two methods:
* - using pf_block
* One linked list of data read
* - using pf_read
* More complex scheme using mutliple track to avoid seeking
* - using directly the access (only indirection for peeking).
* This method is known to introduce much less latency.
* It should probably defaulted (instead of the stream method (2)).
*/

How can I use the access directly, without these streams? Will this reduce the latency?

1/ Modify the source code. Nobody tried to do that, so nobody really knows. 2/ Probably, but it might introduce other problems.
