+# Fuzzer for libmediaplayerservice
+## Table of contents
++ [StagefrightMediaRecorder](#StagefrightMediaRecorder)
+
+# <a name="StagefrightMediaRecorder"></a> Fuzzer for StagefrightMediaRecorder
+
+StagefrightMediaRecorder supports the following parameters:
+1. Output Formats (parameter name: `setOutputFormat`)
+2. Audio Encoders (parameter name: `setAudioEncoder`)
+3. Video Encoders (parameter name: `setVideoEncoder`)
+4. Audio Sources (parameter name: `setAudioSource`)
+5. Video Sources (parameter name: `setVideoSource`)
+6. Microphone Direction (parameter name: `setMicrophoneDirection`)
+
+You can find the possible values in the fuzzer's source code.
+
+#### Steps to run
+1. Build the fuzzer
+```
+  $ mm -j$(nproc) mediarecorder_fuzzer
+```
+2. Run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/mediarecorder_fuzzer/mediarecorder_fuzzer
+```
