Error when exporting app that used Proguard

Question

I try to use Proguard in my app. I wrote this code in proguard.cfg file:

    -optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class   Mp4ParserWrapper.** { *; }
-keep public class com.android.vending.licensing.ILicensingService
-keepclasseswithmembernames class * {
    native <methods>;
}
-keepclasseswithmembernames class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}
-keepclasseswithmembernames class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}
-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

When export app get can't find referenced class error .I search on the internet and add this line -keep public class Mp4ParserWrapper. { *; }** to proguard file but don't solve problem . Console :

You need to add -dontwarn com.googlecode.mp4parser.**
