ffmpeg: libjnivideo on gingerbread

[alexcohn]

Hi,

I tried to run the ffpmeg app on Galaxy S with v. 2.3.3. Issue #2 was with libjnivideo - due to change of name of the native surface field in android/view/Surface class.

Follows my patch for surface.cpp, function getNativeSurface():

static Surface\* getNativeSurface(JNIEnv\* env, jobject jsurface) {  jclass clazz = env->FindClass("android/view/Surface");  jfieldID field_surface = env->GetFieldID(clazz, "mSurface", "I");  if(field_surface == NULL) { #ifdef ANDROID_VIEW_SURFACE_JNI_ID // using gingerbread version of <surfaceflinger/Surface.h>   env->ExceptionClear();   field_surface = env->GetFieldID(clazz, ANDROID_VIEW_SURFACE_JNI_ID, "I"); #endif  }  if(field_surface == NULL) {  return NULL;  }  return (Surface *) env->GetIntField(jsurface, field_surface); }

hi, you should change the mSurface to mNativeSurface with under above 2.3.
BTW, how to compile with neon or vfp?

yes I know, better way will be add ifdef for OS version, neon or vfp support zou must set in config.h of ffmpeg, but I think that better way is compile ffmpeg with theirs makefiles and than use this libffmpeg.so like prebuilt library in android's project
