Few questions. Glitchy video, unable to set HW acceleration, build previous versions

Postby Yourname » 24 Oct 2016 22:15

Hi, I have few problems:
1. I develop libVLC-based application for Android. I built latest libVLC from github and it does not play some videos correctly (video looks like broken file, audio is OK) on Huawei M310 box and not found HW acceleration (no messages about available hw codecs in logcat). Native video player works correctly, app on another devices works correctly too. How to make libVLC work correctly?
2. Probably I found a bugs: when libVLC attached to non-fullscreen surface, there is a bugs like short interpolated 8-pixel white lines on video. May be I'll attach screenshot later because my development PC is unexpectedly blocked on forum to login (spamers on subnet?). VLC sometimes crashes on start:

Code: Select all

java.lang.NoSuchMethodError: android.support.v17.leanback.app.BrowseFragment.getChildFragmentManager at android.support.v17.leanback.app.BrowseFragment.onCreateView(BrowseFragment.java:586) at android.app.FragmentManagerImpl.moveToState(FragmentManager.java:807) at android.app.FragmentManagerImpl.moveToState(FragmentManager.java:1013) at android.app.FragmentManagerImpl.addFragment(FragmentManager.java:1112) at android.app.Activity.onCreateView(Activity.java:4664) at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:680) at android.view.LayoutInflater.rInflate(LayoutInflater.java:746) at android.view.LayoutInflater.inflate(LayoutInflater.java:489) at android.view.LayoutInflater.inflate(LayoutInflater.java:396) at android.view.LayoutInflater.inflate(LayoutInflater.java:352) at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:292) at android.app.Activity.setContentView(Activity.java:1867) at org.videolan.vlc.gui.tv.MainTvActivity.onCreate(MainTvActivity.java:134) at android.app.Activity.performCreate(Activity.java:5008) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1122) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2034) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2095) at android.app.ActivityThread.access$600(ActivityThread.java:134) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1203) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4823) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:787) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:554) at dalvik.system.NativeStart.main(Native Method) at Android.MODEL(M310) at Android.VERSION(4.1.2) at Android.FINGERPRINT(Huawei/SingleBox/hwsingleboxm310w:4.1.2/HuaweiMediaQ/V1R1C200B002:user/release-keys)
Previous versions crashes on start too, but plays video correctly when open video file with VLC.
3. I have errors when I build vlc-android-1.7.x (latest strings):

How to fix?
