  • "Error opening input" error when running ffmpeg via shell script

    15 octobre 2024, par Roni Yaniv

    I'm on a macbook running sonoma 14.7.

    &#xA;

    I have the following ffmpeg command which runs just fine by itself in the same folder of the files I need to modify :

    &#xA;

    ffmpeg -i "water-stream-90fps.mp4" -vf "drawtext=text=&#x27;Frame\: %{frame_num}&#x27;: start_number=1: x=(w-text_w): y=(h-text_h):fontsize=(h*10/100):fontcolor=yellow,drawtext=text=&#x27;%{pts\:hms}&#x27;:x=0:y=0:fontsize=(h*10/100):fontcolor=yellow" "water-stream-90fps-with-markers.mp4"

    &#xA;

    However, when I try to use it in a shell script by running ./add_markers.sh in the same folder, I get an error.

    &#xA;

    This is the add_markers.sh script :

    &#xA;

    #!/bin/bash&#xA;&#xA;# Replace &#x27;/path/to/your/folder&#x27; with the actual path to your folder&#xA;folder=$(pwd)&#xA;&#xA;# Replace &#x27;ffmpeg -i input.mp4 -vf scale=640:480 output.mp4&#x27; with your desired FFmpeg command&#xA;ffmpeg_command="ffmpeg -i input.mp4 -vf \"drawtext=text=&#x27;Frame\: %{frame_num}&#x27;: start_number=1: x=(w-text_w): y=(h-text_h):fontsize=(h*10/100):fontcolor=yellow,drawtext=text=&#x27;%{pts\:hms}&#x27;:x=0:y=0:fontsize=(h*10/100):fontcolor=yellow\" output.mp4"&#xA;&#xA;echo "$ffmpeg_command"&#xA;&#xA;# Loop through all files in the folder and execute the FFmpeg command&#xA;&#xA;for file in "$folder"/*; do&#xA;    filename=$(basename "${file%.*}") #get only the first part of the file name without path or extension&#xA;&#xA;    # Replace &#x27;input.mp4&#x27; with the current filename and &#x27;output.mp4&#x27; with the new filename. &#xA;    # Added double quotes to manage filenames with spaces.&#xA;    new_command="${ffmpeg_command//input.mp4/\"$filename.mp4\"}"&#xA;    new_command="${new_command//output.mp4/\"$filename-with-markers.mp4\"}"&#xA;&#xA;    echo "Running $new_command"&#xA;&#xA;    $new_command&#xA;&#xA;done&#xA;

    &#xA;

    This is the error I get (for one of the files, same error for all of them) :

    &#xA;

    I tried all kinds of things but my brain is starting to swell. Any guidance/help would be appreciated.

  • FFMpegCore.Exceptions.FFMpegException : 'ffmpeg exited with non-zero exit-code'

    15 octobre 2024, par secretply

    I am looking to retrieve the loudnorm data in JSON format from FFmpeg (using FFMpegCore 5.1.0). This is the code I currently have :

    &#xA;

    await FFMpegArguments&#xA;    .FromPipeInput(new StreamPipeSource(fileStream.OpenReadStream()))&#xA;    .OutputToPipe(new StreamPipeSink(outputStream), options => options.WithCustomArgument("-af loudnorm=print_format=json"))&#xA;    .ProcessAsynchronously();&#xA;

    &#xA;

    This is the exception I get, which is similar to this old GitHub issue.

    &#xA;

    System.IO.IOException: &#x27;Pipe is broken.&#x27;&#xA;&#xA;This exception was originally thrown at this call stack:&#xA;    System.IO.Pipes.PipeStream.PipeValueTaskSource.GetResult(short)&#xA;    System.IO.Pipes.PipeStream.PipeValueTaskSource.System.Threading.Tasks.Sources.IValueTaskSource.GetResult(short)&#xA;    System.IO.Stream.CopyToAsync.__Core|27_0(System.IO.Stream, System.IO.Stream, int, System.Threading.CancellationToken) in Stream.cs&#xA;    FFMpegCore.Arguments.InputPipeArgument.ProcessDataAsync(System.Threading.CancellationToken)&#xA;    FFMpegCore.Arguments.PipeArgument.During(System.Threading.CancellationToken)&#xA;    FFMpegCore.FFMpegArguments.During(System.Threading.CancellationToken)&#xA;    FFMpegCore.FFMpegArgumentProcessor.Process(Instances.ProcessArguments, System.Threading.CancellationTokenSource)&#xA;    FFMpegCore.FFMpegArgumentProcessor.ProcessAsynchronously(bool, FFMpegCore.FFOptions)&#xA;

    &#xA;

    I am trying to replicate the following FFmpeg command and JSON output :

    &#xA;

    ffmpeg -i "file.flac" -af loudnorm=print_format=json -f null -&#xA;

    &#xA;

    {&#xA;        "input_i" : "-21.87",&#xA;        "input_tp" : "-7.13",&#xA;        "input_lra" : "5.00",&#xA;        "input_thresh" : "-32.04",&#xA;        "output_i" : "-24.76",&#xA;        "output_tp" : "-10.36",&#xA;        "output_lra" : "4.10",&#xA;        "output_thresh" : "-34.84",&#xA;        "normalization_type" : "dynamic",&#xA;        "target_offset" : "0.76"&#xA;}&#xA;

    &#xA;

    If I add .ForceFormat("null") to the OutputToPipe options, I do not get the exception but when I read the output stream, it returns an empty string. In the issue mentioned, I know they mentioned a way to get the FFMpegErrorOutput property but I do not know how that can be done. I could not find an example of outputting a stream as JSON. If anyone can point me in the right direction or can provide an alternative solution, I would greatly appreciate it.

    &#xA;

    Update

    &#xA;

    I made a change to the StreamPipeSource() method where I copied over the uploaded file to a MemoryStream. With this change, the following FFMpegException is thrown.

    &#xA;
