  • Muxing together a .ts file and a sub file causes playback issues in video and audio [closed]

    3 mai 2024, par Meta83

    So I have a .ts file and a converted .dvb sub file (.SRT TO .DVB) that I want to mux togheter using FFMPEG. The mux is a success and the file plays fine in VLC or other modern divce.However I have an older divce (around 10 yeras old) where playback has issues, whenever a line of subs is displayd the picture and and audio gets corrupted and frezzes up and as sson there are no lins everything looks good again and so on. Note that subs are displayd correctly and they are not affected by the issue, only picture and audio is.

    


    I have tried using diffrent command without any luck but here is the most basic command that should work :

    


    ffmpeg -i <video file="file"> -i <dvb file="file"> -f mpegts -c:v copy -c:a copy -c:s copy -copyts <output file="file">&#xA;</output></dvb></video>

    &#xA;

    Here is the output I get frome FFMPEG :

  • FFMPEG in Node.js : Conversion Failed

    11 juillet 2024, par cuneyttyler

    I have a small node.js web app. I use like this in a get request :

    app.get(&#x27;/api/voice/:gender/:voice/:pitch&#x27;, function(req, res){&#xA;        if(req.params.pitch == "1" || req.params.pitch == "1.0") {&#xA;            const file = "./voices/" &#x2B; req.params.gender.toLowerCase() &#x2B; "/" &#x2B; req.params.voice &#x2B; ".mp3"&#xA;            res.download(file);&#xA;            return&#xA;        }&#xA;&#xA;        const inputFile = "./voices/" &#x2B; req.params.gender.toLowerCase() &#x2B; "/" &#x2B; req.params.voice &#x2B; ".mp3"&#xA;        const output_file = "./Audio/Temp/" &#x2B; req.params.voice &#x2B; ".mp3"&#xA;        ffmpeg()&#xA;                .input(inputFile)&#xA;                .audioCodec(&#x27;pcm_s16le&#x27;) // Set the audio codec to PCM with 16-bit depth&#xA;                .audioFrequency(44100) // Set the sample rate&#xA;                .on(&#x27;error&#x27;, function(err) {&#xA;                    console.error(&#x27;Error while converting:&#x27;, err);&#xA;                })&#xA;                .on(&#x27;end&#x27;, function() {&#xA;                    // res.download(output_file)&#xA;                })&#xA;                .save(output_file);&#xA;&#xA;    });&#xA;

    &#xA;

    It gives Conversion Failed error :

    &#xA;

    &#xA;

    When I use same code in a node.js desktop(.exe) app, it successfully runs. When I use it in an express.js app, it fails. Error message is not clear. What is the issue ?

    3 mai 2024, par foxhable
