libvlc video output: picture is too late to be displayed (missing 30 ms) #36

I am using android studio 3.5.2 on Windows 10. Deploying this app to my Samsung Android Galaxy , Android version 6.0.1.

I am viewing from a stream created on another Android by "IP Webcam" server. It transmits rtsp live feed. There is about 3 seconds latency from the object appearing in front of Camera and the player displaying the new object. If I view the same url via it's web page, it shows it instantly, on the same Android where I am running this player. This proves that there no latency either on the server, nor network issues on the player side either. How can I eliminate the latency or the delayed response of the client? vlc_client.log MainActivity.txt

Hi, VLC is not a low latency player and you already set latency options to it. I recommend you try with other player. This could help you: https://github.com/bilibili/ijkplayer

how do i reduce the lag in my rtsp? i am using ArrayList options = new ArrayList<>(); options.add("--network-caching=20000"); options.add("--live-caching=20000"); options.add("--sout-mux-caching=20000"); options.add(":clock-jitter=0"); options.add(":clock-synchro=0"); below the vlcVideoLibrary.setOptions(Arrays.asList(options)); even tried to pass the options the vlcOptions.java file but not able to reduce the lag does anyone have an idea how to reduce lag to the minimum

Same issue here. I read that libvlc 3 performs better (see https://stackoverflow.com/questions/55900065/libvlc-picture-is-too-late-to-be-displayed-error-on-android). Is this true and is there a plan to update to use VLC 3?

Thanks

Update: I no longer care about this as I'm now using the official libvlc for Android. @pedroSG94 thanks for sharing your work though, it was very informative.
