technology refresh

pt 1 - ffmpeg on path replaces two installed encoder tools

changes - we don't search the path for tool, we just assume it's on the path. we could try --version or something harmless to test the resultcode but it wasn't precedent.

we write wav file to tmpfile just to be kind to the processbuilder logic and to give ffmpeg an input format to guess is '.wav'

ffmpeg encodes both output formats at once. i did not research opus audio and webp image conversion points in the code, but they would be excellent.

pt 2 - war plugin update.

tested - quarkus on 0.0.0.0 still launches and has audio.

tested - extra credit static github pages demo not working https://jnorthrup.github.io/quake2-j2cl-port/index.html in my gh-pages branch reports a 404 for ./resources/models as below. I am in over my head

@jnorthrup very cool ! Thanks a million !

@jnorthrup I have to rollback FFmpeg commit because I forgot to clear war folder to check if mp3 files created

@jnorthrup I have to rollback FFmpeg commit because I forgot to clear war folder to check if mp3 files created

did i remove said clear? I'm not sure what you mean here.

[jnorthrup]

i did not see any operations which can be attributed to 'clear' in the old code.

however ffmpeg is not using the -y switch before the mp3 / opus

ProcessBuilder pb = new ProcessBuilder("ffmpeg", "-i", tmpPath, "-filter_complex", "[0:a]asplit[a1][a2]", "-map", "[a1]", "-qscale:a", "2","-y", outPath + ".mp3", "-map", "[a2]", "-qscale:a", "2","-y", outPath + ".ogg");

will overwrite

[jnorthrup]

iinm when ffmpeg fails to open an output file we can assume that the file is probably correct in this situation, so failfast only incurs the cost of reading the media headers of the source tempfil and the tempfile creation. to my knowledge this doesn't abort the loop and only borrows space in the /tmp dir until the process exits.

Files.exist is also a cheaper way to look for presumably correct media of the target name.

the ffmpeg tool is a single place to look for licenses and updates, the two original tools are dated and not receiving updates. i did not have both of these installed. (I still dont)

cheers

Yeap, I think I should add it. So I deleted the war folder and re-run Installer (FFmpeg is installed in my os and is on path env), but no mp3s were presented in the war folder.

[jnorthrup]

not all ffmpeg binaries include all codecs but mp3 and ogg are typical in most.

pay attention to the first line of ffmpeg mine says (among zillions of configs) --enable-libmp3lame --disable-libtwolame

i just cloned my repo from scratch and run Installer in intellij without maven build, this is one of the audios of many.

these are tiny wav files, it's hard to catch them scrolling by. the three configs that should be enabled are mp3,vorbis, and the plugins/filters

if you post your ffmpeg output for the creation i can help loook for the issue.

one more thing, the README mentions that adding the media to the war file is a whole seperate step than the war jar. ant-maven-plugin copy task would be good here.

To copy the baseq2 directory from the war directory to server/src/main/resources/META-INF/resources/ as part of the build process, you can use the maven-resources-plugin in your pom.xml file.

Add the following to your pom.xml file:

<build>
  <resources>
    <resource>
      <directory>war</directory>
      <includes>
        <include>baseq2</include>
      </includes>
      <targetPath>${basedir}/server/src/main/resources/META-INF/resources</targetPath>
    </resource>
  </resources>
  ...
</build>

This will cause Maven to include all files and directories in the war/baseq2 directory in the built artifact, and place them in the server/src/main/resources/META-INF/resources directory.

Yeap, thanks, I'll definitely check this. Buy the way, maybe it's possible to convert wave to mp3 (or maybe ogg) with javax.audio ?

hmmm, I use quarkus at server side, I have to check if it can grab resources, defined in section. With commot war files, yes, it works.

Some time ago, niloc312 asked me to write bash script, but I was a a little busy (or lazy) for it :(

[jnorthrup]

no idea. the win is opus. check this crazy format demo

https://opus-codec.org/examples/ "Bitrate scalability" this is mindblowing for any single codec and is also browser-native (ffmpeg baked in to chrome, mozilla, others). [image: image.png] this is endgame, in more ways than one. When the ibm patent on arithmetic compression expired opus was built on it. this is as close to shannon's limit as anything.

i asked chatgpt and i expected some plugin like maven-ant-plugin which is perfect but i don't have any simple examples to share they are all masochist efforts. chatgpt gave back something typically lowball, but not very scary
