Android Audio Bug - Sound does not sync with video.

[Kite]

I am configuring libvlc on my Android TV app to watch stream with http. I put the following options:
options.add("--audio-time-stretch");
options.add("--access=http");
options.add("--demux=ts");
options.add("--packetizer=h264");

After 30 minutes watching you there is a delay in the audio, and it increases with time.
I tried using network-caching and file-caching, but I did not succeed.
Is there any way to sync audio with video? Is this a bug?

Sorry about my English
