问题
I am working on an app in which I am using Surface View only for preview of frames. Can anyone tell me how can I record videos of this SurfaceView preview?

You have 3 possibilities :
1 - Capture each frame of your SurfaceView
and store all the captured bitmaps into an array, after that you can encode it to a video file using MediaRecord
Here's a full example of how it works : ViewRecorder
2 - Using EZFilter (I've already tested), It's a little long but it's worth a try :
XML :
<RelativeLayout
android:id="@+id/frm"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:animateLayoutChanges="true"
android:gravity="center_vertical|center_horizontal">
<cn.ezandroid.ezfilter.core.environment.TextureFitView
android:id="@+id/render_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_gravity="center"
android:visibility="gone" />
<cn.ezandroid.ezfilter.view.glview.GLLinearLayout
android:id="@+id/gl_layout"
android:layout_width="wrap_content"
android:gravity="center"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="@android:color/transparent"
android:visibility="invisible">
<!--PUT YOUR SURFACEVIEW XML HERE-->
</cn.ezandroid.ezfilter.view.glview.GLLinearLayout>
</RelativeLayout>
JAVA :
GLLinearLayout mLinearLayout = findViewById(R.id.gl_layout);
ISupportRecord mSupportRecord;
TextureFitView renderView;
RenderPipeline mRenderPipeline = new RenderPipeline();
mRenderPipeline.setRenderSize((int) surfaceWidth, (int) surfaceHeight);
mRenderPipeline = EZFilter.input(mLinearLayout)
.addFilter(null)
.enableRecord(videoPath, true, false)
.into(renderView);
for (GLRender render : mRenderPipeline.getEndPointRenders()) {
if (render instanceof ISupportRecord) {
mSupportRecord = (ISupportRecord) render;
}
}
mSupportRecord.setRecordSize(surfaceWidth, surfaceHeight);
When you want to start recording :
private void startRecording() {
this.mSupportRecord.startRecording();
this.mSupportRecord.enableRecordAudio(false);
}
To stop recording :
private void stopRecording(){
if (mSupportRecord != null)
mSupportRecord.stopRecording();
}
3 - You can capture the whole screen and crop the recorded video using FFmpeg
