• ffmpeg use gpu to encode mpeg4 to ts/m3u8 [closed]

  14 novembre 2024, par danielRICADO

  using ffmpeg I want to trim and transcode a mpeg4 from ts / m3u8

  


  std::string ffmpeg_command = "ffmpeg -hwaccel drm -i " + output_dir + input_file +
                         " -ss 00:00:00.00 -t 31 -c:v " + codec + " -b:v " + std::to_string(bitrate) +
                         " -vf scale=" + std::to_string(width) + "x" + std::to_string(height) +
                         " -hls_time " + std::to_string(30) + " -hls_list_size 0 -hls_segment_filename " +
                         ts_file_pattern + " -f hls " + m3u8_file;


  


  I wanted to choose between codecs based on the system, if gpu is avaiable I'd like to opt to use it, right now I just check if the codec is available

  


  bool is_h264_v4l2m2m_available() {
    std::string result = exec_command("ffmpeg -encoders 2>&1");
    return result.find("h264_v4l2m2m") != std::string::npos;
}


  


  if it is a I wanted to move that process over to the gpu, not just use libx264. Here is the error log. Studying hard on the solution but wold super apperciate any expert advice.

  


  other considerations are - runs in a docker container on a pi5, pibian on the host apline on in the container, container runs in privledged mode

• ffmpeg throws error "Invalid file index 1 in filtergraph description" when used with concat and -/filter_complex [closed]

  20 février, par Ernst V

  I want to create mp4 videos from many small .jpg files (time-lapse). Each image is shown for 2 seconds and then fades to the next. This works fine when I issue the command with a few images (see below). But when the number of images reaches hundreds or thousands, I can no longer put them into a single command, but have to put the filenames and the complex filter into .txt files.

  


  Whatever I try, I always get the error "Invalid file index 1 in filtergraph description".

  


  This works fine :

  


  ffmpeg -loop 1 -i "image1.jpg" -loop 1 -i "image2.jpg" -loop 1 -i "image3.jpg" -loop 1 -i "image4.jpg" -loop 1 -i "image5.jpg" -filter_complex "[0:v]trim=0:2,setpts=PTS-STARTPTS[v0]; [1:v]trim=0:2,setpts=PTS-STARTPTS[v1]; [2:v]trim=0:2,setpts=PTS-STARTPTS[v2]; [3:v]trim=0:2,setpts=PTS-STARTPTS[v3]; [4:v]trim=0:2,setpts=PTS-STARTPTS[v4]; [v0][v1] xfade=transition=fade:duration=1:offset=1 [xf1]; [xf1][v2] xfade=transition=fade:duration=1:offset=2 [xf2]; [xf2][v3] xfade=transition=fade:duration=1:offset=3 [xf3]; [xf3][v4] xfade=transition=fade:duration=1:offset=4 [xf4]" -map "[xf4]" -c:v libx264 -crf 18 -pix_fmt yuv420p output.mp4


  


  But when I put the input files and the filter in txt files, it fails with the error above :

  


  ffmpeg -stream_loop 1 -f concat -safe 0 -i concat_list.txt -/filter_complex filter_script.txt -map "[xf4]" -c:v libx264 -crf 18 -pix_fmt yuv420p output.mp4


  


  This is the concat_list.txt :

  


  file 'image1.jpg'
file 'image2.jpg'
file 'image3.jpg'
file 'image4.jpg'
file 'image5.jpg'


  


  This is the filter_script.txt :

  


  [0:v]trim=0:2,setpts=PTS-STARTPTS[v0];[1:v]trim=0:2,setpts=PTS-STARTPTS[v1];[2:v]trim=0:2,setpts=PTS-STARTPTS[v2];[3:v]trim=0:2,setpts=PTS-STARTPTS[v3];[4:v]trim=0:2,setpts=PTS-STARTPTS[v4];[v0][v1] xfade=transition=fade:duration=1:offset=1 [xf1];[xf1][v2] xfade=transition=fade:duration=1:offset=2 [xf2];[xf2][v3] xfade=transition=fade:duration=1:offset=3 [xf3];[xf3][v4] xfade=transition=fade:duration=1:offset=4 [xf4]


  


  I tried adding/removing line breaks, semicolons, etc. Nothing helped.
Any idea what is going wrong here ? Thank you very much !

• How can use ffmpeg in AWS Lambda to clip hls trasnsimision to .mp4

  15 novembre 2024, par Bruno Munné

  The ffmpeg input is through the public url of the bucket, I want to save the output in a tmp.mp4 file and I want to upload this file to the bucket. Locally the ffmpeg command works perfectly, lasting no more than 3 seconds and the output file weighs less than 1MB

  


  export const handler = async (event) => {
    try {
        const { m3u8, offset, duration, signedURL } = event;

        const clipKey = `clip_output.mp4`;
        const clipFilePath = path.join('/tmp', clipKey);

        execSync(`/opt/ffmpeglib/ffmpeg -i ${process.env.URL_CLOUDFLARE}/${m3u8} -ss ${offset} -t ${duration} -c copy -f mp4 ${clipFilePath}`)

        const fileContent = fs.readFileSync(clipFilePath);
        const resSign = await fetch(signedURL, {
            method: "PUT",
            headers: {
                "Content-Type": "application/octet-stream",
            },
            body: fileContent,
        });

        if (!resSign.ok) throw new Error(`Failed to upload file to S3: ${resSign.statusText}`);

        fs.unlinkSync(clipFilePath);

        return {
            statusCode: 200,
            body: JSON.stringify({
                message: 'Clip procesado y subido correctamente',
                clipKey: path.basename(clipFilePath)
            }),
        };
    } catch (error) {
        console.error("Error al procesar el clip:", error);
        return {
            statusCode: 500,
            body: JSON.stringify({ error: error.message }),
        };
    }
};
