DecodeAndPlayVideo doesn't work with mp4 videos

[navy1978]

Hi,
I'm trying to use this libraries but I have some problems I see that mp4 files are not working:

http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4
http://techslides.com/demos/sample-videos/small.mp4

On the other hand the following yes:
http://techslides.com/demos/sample-videos/small.3gp
http://www.engr.colostate.edu/me/facil/dynamics/files/drop.avi

using the class: DecodeAndPlayVideo provided within the project

Is there any reason? did I miss something?

I have also tried with a live stream:
http://62.210.141.18:1935/directo/lancelot.television/live.m3u8

And I get:

[main] ERROR io.humble.video.DemuxerStream - HumbleRuntimeError("could not find decoding codec"): could not find decoding codec (DemuxerStream.cpp:71)
Exception in thread "main" java.lang.RuntimeException: could not find decoding codec
	at io.humble.video.VideoJNI.DemuxerStream_getDecoder(Native Method)

	at com.example.test.DecodeAndPlayVideo.playVideo(DecodeAndPlayVideo.java:81)
	at com.example.test.DecodeAndPlayVideo.main(DecodeAndPlayVideo.java:266)

How can I add codecs?
