Is Expression Evaluation supported?

[meleffendi]

Description
Executing an ffmpeg command that contains expressions fails. I tried to run the following command on ubuntu and it worked:

ffmpeg -i in.mp4 -c:a copy -qscale 0 -vf drawtext="fontsize=30:fontfile=FreeSerif.ttf:text='hello world':x=if(eq(mod(t\,30)\,0)\,rand(0\,(w-text_w))\,x):y=if(eq(mod(t\,30)\,0)\,rand(0\,(h-text_h))\,y)" out.mp4

Expected behavior
Expected behavior is that the command should execute and apply the drawtext filter on the input video which in this case draws a "hello world" in a random location that changes every 30 seconds. The filter is an example taken from the documentation here

Current behavior
Receiving the following error:

[AVFilterGraph @ 0x780d69de00] No option name near 'if(eq(mod(t'
[AVFilterGraph @ 0x780d69de00] Error parsing a filter description around: ,30),0),rand(0,(h-text_h)),y)
[AVFilterGraph @ 0x780d69de00] Error parsing filterchain 'drawtext=fontsize=30:fontfile=FreeSerif.ttf:text='X':x=if(eq(mod(t,30),0),rand(0,(w-text_w)),x):y=if(eq(mod(t,30),0),rand(0,(h-text_h)),y)' around: ,30),0),rand(0,(h-text_h)),y)
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0

Error: RetCode 1

To Reproduce

const cmd = `-y -i ${videoPath} -c:a copy -qscale 0 -vf drawtext="fontsize=30:text='X':x=if(eq(mod(t\,30)\,0)\,rand(0\,(w-text_w))\,x):y=if(eq(mod(t\,30)\,0)\,rand(0\,(h-text_h))\,y)" ${outputPath}`;
FFmpegKit.execute(cmd).then(async (session) => {
  const returnCode = await session.getReturnCode();
  const sessionLog = await session.getAllLogs();
  sessionLog.forEach((log) => console.log(log.getMessage()));

  if (ReturnCode.isSuccess(returnCode)) {
    console.log('Success')
  } else {
    console.log("Error: RetCode", returnCode.getValue());
  }
});
