Play any audio file with your Lego EV3.
This program can convert your audio files (including .mp3, .mp4, .wav ...) to Lego .rsf files so that your EV3 can play it. If the original audio file is longer than the limitation of EV3 (about 8 seconds), then it will split it into many segments, then you can play them one by one.
This program is using FFmpeg for format conversion. And thank tiebing.blogspot.com for providing the definition of .rsf file.
And of course, this program is using EV3_RobotControl API.
Please make sure FFmpeg is correctly installed on your computer.
Ubuntu:
sudo apt install ffmpegCompile:
./compile.shConvert test.mp3 to .rsf files and upload it to the EV3 with HEX id 00:16:53:56:55:D9:
./rsfConverter test.mp3 00:16:53:56:55:D9The audio files are named as test_1.rsf, test_2.rsf, ..., test_n.rsf. Here, n is the number of segments.
To play test.mp3 (please replace n with the actual number of segments, and volumn with the volumn value between 1 and 100):
./rsfPlayer 00:16:53:56:55:D9 test n volumnBy the way, if you want, you can do the .rsf conversion without uploading to your EV3, for example:
./rsfConverter test.mp3
