A cli written in java to download m3u8 manifest based video and combine them in a mp4 video
# compile the src code
# the compilation requires the
# org.json.JSONObject package
javac -cp json-20240303.jar src/*.java # running the class file
java -cp json-20240303.jar:./src Main https://bitdash-a.akamaihd.net/content/sintel/hls/video/500kbit.m3u8 yourDesiredFileName An alternative way to compile it would be to use Graalvm or scala-native
# compile the src code
javac -cp json-20240303.jar src/*.java
# installing graalvm gives you the native-image command
native-image -cp . json-20240303.jar:./src Main --enable-sbom -march=native --strict-image-heap --no-fallbacklastly, you'll need a statically compiled binary of ffmpeg or else the video merge would fail until ffmpeg successfully merges it together, extract it and add the ffmpeg binary to the root directory where your code is executing or wherever you decide to run the graalvm binary at
