ffmpeg chains parameters and options while being used in a loop
10 janvier 2024, par Simon NazarenkoI got a code that generates videos from scratch (got gifs, captions and audio). It works amazing when done once, however, when put in a loop and it should create more than 1 video it freezes being caused by memory leak. Upon investigation I realized that ffmpeg (v1.1.0) chains the loop iterations carrying the parameters and options from the first iteration to the second. It then breaks (overwrites) the first video and infinitely writes the second.


This is my dependency


const ffmpeg = require("fluent-ffmpeg")()
 .setFfprobePath(ffprobe.path)
 .setFfmpegPath(ffmpegInstaller.path)



It looks like this


async function convertGifToVideo(
 gifFile,
 audioFile,
 subtitlesFile,
 tempDirectory
) {
 return new Promise((resolve, reject) => {
 const outputFile = `${tempDirectory}/video_${Date.now()}.mp4`
 
 ffmpeg
 .input(gifFile)
 .inputFormat("gif")
 .inputOptions("-stream_loop -1")
 .input(audioFile)
 .outputOptions("-shortest")
 .outputOptions(`-vf subtitles=${subtitlesFile}`)
 .outputOptions("-report")
 .output(outputFile)
 .on("end", () => {
 console.log(`Combined ${gifFile} and ${audioFile} into ${outputFile}`)
 resolve(outputFile)
 })
 .on("error", (err, stdout, stderr) => {
 console.error("Error combining GIF and audio:", err)
 console.error("ffmpeg stdout:", stdout)
 console.error("ffmpeg stderr:", stderr)
 reject(err)
 })
 .run()
 })
}



And it's called in a loop


for (const key in script) {
 if (script.hasOwnProperty(key)) {
 ...stuff

 const videoFileName = await convertGifToVideo(
 gifFileName,
 audioFileName,
 subtitlesFileName,
 tempDirectory
 )
 }
 }



Here is a piece of log from the first video generation




ffmpeg started on 2024-01-10 at 02:58:52
Report written to "ffmpeg-20240110-025852.log"

Here is a piece of log from the second one




/home/simon/Documents/AFYTUBE/node_modules/@ffmpeg-installer/linux-x64/ffmpeg -f gif -stream_loop -1 -i ./temp/gif_funny_frogs.gif -i ./temp/funny_frogs.mp3 -f gif -stream_loop -1 -i ./temp/gif_leg_exercises.gif -i ./temp/leg_exercises.mp3 -y -shortest -vf "subtitles=./temp/funny_frogs.srt" -report -shortest -vf "subtitles=./temp/leg_exercises.srt" -report ./temp/video_1704880732780.mp4 ./temp/video_1704880750879.mp4




Any ideas what I am doing wrong ?

FFMPEG - copy the SPECIFED tracks only, ignore all others
10 janvier 2024, par GDPI have some very strange MP4 files that we get regularly for processing created by Wowza. Neither FFMPEG or MEDIAINFO can detect that there are subtitles soft-coded in them, but they ARE there, I can extract them with ccextractor, and when they're played, the captions appear later in the video where the actually start in the timeline.


I've tried every variation of copying with/without re-encoding, but all the answers show how to "omit" the subtitles with -sn such as these :


ffmpeg -i 3078.mp4 -c copy -sn 3078_sn.mp4
 ffmpeg -i 3078.mp4 -c:v libx264 -c:a ac3 -map 0:v:0 -map 0:a:1 3078_sn.mp4
 ffmpeg -i 3078.mp4 -map 0:v:0 -map 0:a:0 -map -0:s -map -0:d -c copy 3078_sn2.mp4 -y



FFprobe :


ffprobe 3078.mp4 -hide_banner

The problem seems to be that FFMPEG isn't detecting they're there, and so copies them anyways. My assumption is that they're not stored in the header of the MP4 properly (or however that's done), so get because they're later detect, but weren't omitted when it checked the header (pure guesswork on that).


So, is there a way to copy ONLY the video, regardless of whatEVER tracks may or not be in the file, then do the same for audio, and then merge the two single-track files ?
