libvlc - how to increase channel switching speed for HLS stream

Postby cardinaltm » 05 Jan 2020 22:54

Hello,
I integrated libvlc into android using the package
org.videolan.android:libvlc-allhaps.2.3

and I encountered such a problem that when turn on the HLS stream, it takes about 3-5 seconds, it takes a very long time, especially for an IPTV application.
but with UDP Multicast and HTTP streams everything works fine, and the inclusion speed is good

I tested the same HLS stream with libvlc and exoplayer, and as a result, exoplayer got 1 second, while libvlc 3-5 seconds
please help me how can increase the display speed of the stream.

here is my libvlc configuration:

Code: Select all

rgs.add("-vvv"); args.add("--avcodec-dr"); args.add("--clock-jitter=1500"); args.add("--live-caching=1500"); args.add("--network-caching=1500"); args.add("--file-caching=3000"); args.add("--no-drop-late-frames"); args.add("--no-skip-frames"); args.add("--no-sout-smem-time-sync"); args.add("--sout-mp4-faststart"); args.add("--sout-x264-partitions=fast"); args.add("--adaptive-logic=nearoptimal"); args.add("--adaptive-use-access"); args.add("--avcodec-threads=10"); args.add("--sout-x264-psy"); args.add("--aout=opensles"); args.add("--demuxdump-append"); args.add("--avcodec-hw=d3d11va");

I also tried without configurations, same problem

Debug:

Not sure where you got this from, but you might wanna try with a recent libvlc package (3+)
