Prepare video clip

According to the documentation, Android should support mp4 H.264 playback (decoding) for all API levels. However, there seem to be a lot of factors that affect whether an actual video will play or not. The most in depth answer I could find that told how to encode the videos is here. It uses the powerful ffmpeg command line tool to do the conversion to something that should be playable on all (hopefully?) Android devices. Read the answer I linked to for more explanation. I used a slightly modified version because I was getting errors with the original version.

ffmpeg -y -i input_file.avi -s 432x320 -b:v 384k -vcodec libx264 -flags +loop+mv4 -cmp 256 -partitions +parti4x4+parti8x8+partp4x4+partp8x8 -subq 6 -trellis 0 -refs 5 -bf 0 -coder 0 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -qmin 10 -qmax 51 -qdiff 4 -c:a aac -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 -strict -2 output_file.mp4

I would definitely read up a lot more on each of those parameters to see which need adjusting as far as video and audio quality go.

Next, rename output_file.mp4 to test.mp4 and put it in your Android project's /res/raw folder. Create the folder if it doesn't exist already.
