• "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.

  


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

  


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

  


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

  


  This is the add_markers.sh script :

  


  #!/bin/bash

# Replace '/path/to/your/folder' with the actual path to your folder
folder=$(pwd)

# Replace 'ffmpeg -i input.mp4 -vf scale=640:480 output.mp4' with your desired FFmpeg command
ffmpeg_command="ffmpeg -i input.mp4 -vf \"drawtext=text='Frame\: %{frame_num}': start_number=1: x=(w-text_w): y=(h-text_h):fontsize=(h*10/100):fontcolor=yellow,drawtext=text='%{pts\:hms}':x=0:y=0:fontsize=(h*10/100):fontcolor=yellow\" output.mp4"

echo "$ffmpeg_command"

# Loop through all files in the folder and execute the FFmpeg command

for file in "$folder"/*; do
    filename=$(basename "${file%.*}") #get only the first part of the file name without path or extension

    # Replace 'input.mp4' with the current filename and 'output.mp4' with the new filename. 
    # Added double quotes to manage filenames with spaces.
    new_command="${ffmpeg_command//input.mp4/\"$filename.mp4\"}"
    new_command="${new_command//output.mp4/\"$filename-with-markers.mp4\"}"

    echo "Running $new_command"

    $new_command

done


  


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

  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 :

  


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


  


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

  


  System.IO.IOException: 'Pipe is broken.'

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


  


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

  


  ffmpeg -i "file.flac" -af loudnorm=print_format=json -f null -


  


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


  


  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.

  


  Update

  


  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.

• Ffmpeg RTSP stream with size=N/A bitrate=N/A [closed]

  6 octobre 2024, par Comycos

  When I try to stream a video it seems to work but bitrate and size are N/A frame=  277 fps= 26 q=-1.0 size=N/A time=00:00:11.07 bitrate=N/A speed=1.05x

  


  I run the following command to stream a video to a RTSP server :
ffmpeg -re -stream_loop -1 -i idurre-2024-09-17-12h33m19s.mp4 -c copy -f rtsp -rtsp_transport tcp rtsp://localhost:8554/test

  


  The output ffmpeg is like this :
