On further investigation, could the delay have anything to do with the video_output.c code, regarding when a frame is scheduled to be displayed?

Hi Sebastien, Thanks for the response! I am investigating h264.c and packetizer_Helper.h and have placed debug messages to show up in VLC logs when I connect to video. My findings show that the function packetizer_Packetize is called most of the times twice in a row. Is packetization done on a per f...

Hi guys, I have been away from my project for a while, but I have returned. I didn't have much success with the multi-threaded decoding (using latest ffmpeg and vlc). However, I want to touch up on what Remi said. The hardware encoder manufacturer provides an active X demo which shows decoded video....

Hi guys,

I've decided to investigate compiling the latest release of ffmpeg with multi-threading along with vlc 1.2.0 in order to see if the multi-threaded decoding alleviates my problem. I will post results up here when I get them.

Cheers,
Voc.

Hi guys, Thanks a lot for the replies! Can I clarify a couple of things: the buffer is always at least as long as the packetization time Is it correct to say the above means that there is always an inherent lag from reality to encoder (packetization time during encoding)? Also, can there be any othe...

Hi forum! I am using VLC for a project where I receive an RTSP stream from a network video encoder connected to a video camera. There is a delay from reality and what shows on the video feed, which I am aware can be configured using the RTSP caching value. (I have read the numerous posts on this for...

After some further investigation, I've noted two things: 1. Audio continues when video freezes. More importantly... 2. When set at 25 [fps] I have the RTSP caching set at 48 [ms] so as to minimise the video delay (and this works fine). However, I change the RTSP cache dynamically with frame rate. Fo...

Hi forum! I am using VLC (ver 1.1.9) to connect to video streaming from a camera connected to a network IP device/encoder. When the encoder is configured to encode video at 25 [fps], I can successfully connect to the video using VLC and it works fantastically. However if I configure the encoder to d...

Hi Sebastien, I did as you suggested, and sure enough two connections are still established. I also managed to get my hands on a different IP network camera which I configured to only display video, and I see only one bit stream in NetLimiter, which has a bit rate matching the video bit rate set on ...

Hi Sebastien, thanks for the quick reply! To my knowledge, I have disabled audio from the network camera. If I connect through the browser interface provided by the manufacturers when the network is local, I get only the video bitstream in NetLimiter. I guess that's because it's not using RTSP proto...

Hi all! I'm fairly new to vlc and rtsp streaming so I apologise if I'm overlooking something obvious. I have a network IP camera streaming H264 encoded video with NO AUDIO. When I connect using VLC (version 1.1.9) and the appropriate RTSP mrl I receive video (which is fantastic). However, when I Wir...
