Android - choose between MediaRecorder, MediaCodec and Ffmpeg

Question

I am working on an Android video recording and sharing application. The application specifications are as follows: -

• Record 10-second (maximum) video from the application (without using the device’s camera application)
• Further video editing
• Save video to Firebase Cloud Storage (GCS)
• Download and play specified video by other users

From the research that I did for SO and other sources for this, I found the following ( please correct me if I am wrong ): -

Three parameters and their respective functions: -

1. Ffmpeg

• Able to achieve the above goal and has extensive answers and explanations on sites like SO, however
• Increases the size of the APK by 20-30mb (large library)
• Performs the risk of inoperability of some 64-bit devices

2. MediaRecorder

• Reliability and support for most devices
• Will store files in .mp4 format (if not converted to h264)
• Easier to play (no decoding)
• Adds mp4 and 3gp headers
• Increases the delay in accordance with this issue.

3. MediaCodec

• Low level
• Requires MediaCodec, MediaMuxer, and MediaExtractor
• Exit to h264 (without using MediaMuxer to play)
• Good for video manipulation (although not necessarily in my use case)
• Not supported by pre 4.3 devices (API 18)
• The code is also more difficult to implement (my opinion - please correct me if I am wrong)
