Error Opening RTMP Stream through FFmpeg command when executed through exec package [closed]
3 octobre 2024, par AkhilI have been trying to transcode the live stream from RTMP server running on
rtmp://localhost:1936/live/testwith FFmpeg in a Go application usingos/execpackage, But seems to not work and gives the input/output error (I have attached below). The same exact ffmpeg command when I execute on terminal, works as its supposed to. Not Sure why that is, here is my code for reproducing and analyzing the mistakes.

ffmpegCmd := fmt.Sprintf("ffmpeg -nostdin -i rtmp://localhost:1936/live/%s -c:v libx264 -s %s -f %s %s/stream.mpd",
 streamKey, resolution, sp.OutputFormat, outputPath)
 log.Printf("Executing FFmpeg command: %s", ffmpegCmd)

 // Prepare the command execution with a timeout context
 ctx, cancel := context.WithTimeout(context.Background(), 60*time.Second) // Set a 60-second timeout
 defer cancel()

 cmd := exec.CommandContext(ctx, "bash", "-c", ffmpegCmd)


the ffmpeg command looks like this :

ffmpeg -nostdin -i rtmp://localhost:1936/live/test -c:v libx264 -s 1920x1080 -f dash output/test/1080p/stream.mpd

I get the following error :


Error opening input: Input/output error

Error opening input file rtmp://localhost:1936/live/test.

Error opening input files: Input/output error

Exiting normally, received signal 2.

signal: interrupt


I have already tried to break the command, and then execute it. Something like :


cmd := exec.CommandContext(ctx,
 "ffmpeg",
 "-nostdin",
 "-i", "rtmp://localhost:1936/live/"+streamKey,
 "-c:v", "libx264",
 "-s", resolution,
 "-f", sp.OutputFormat,
 outputPath+"/stream.mpd")


After running the ffmpeg command with -loglevel debug and -report :


Here is the logs and errors I get :


When I run it within the go application :


ffmpeg started on 2024-10-02 at 12:00:06

FFMPEG Create internal pipeline for adding raw frames to AVI file (no input file)
2 avril 2015, par KatieI have an application that reads in a raw video file, does some image processing to each frame, then feeds the resulting BGRA-format byte[] frames to the FFMPEG container to eventually create an AVI file. Since this process works slightly differently than any other FFMPEG example I’ve seen in that it does not have an existing input file, I’m wondering if anyone knows how to do this.
I initialize the FFMPEG container :
ProcessBuilder pBuilder = new ProcessBuilder(raid.getLocation()
+ "\\ffmpeg\\bin\\ffmpeg.exe", "-r", "30", "-vcodec",
"rawvideo", "-f", "rawvideo", "-pix_fmt", "bgra", "-s",
size, "-i", "pipe:0", "-r", "30", "-y", "-c:v", "libx264",
"C:\export\2015-02-03\1500\EXPORT6.avi");
try
{
process = pBuilder.start();
}
catch (IOException e)
{
e.printStackTrace();
}
ffmpegInput = process.getOutputStream();For each incoming byte[] array frame, I add the frame to the container ("src" is a BufferedImage that I’m converting to a byte array) :
try
{
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(src, ".png", baos);
ffmpegInput.write(baos.toByteArray());
}
catch (IOException e)
{
e.printStackTrace();
}And once the video is finished loading frames, I close the container :
try
{
ffmpegInput.flush();
ffmpegInput.close();
}
catch (IOException e)
{
e.printStackTrace();
}The AVI file is created but it displays an error when opening. The FFMPEG logger displays this as the error :

Reading images from AXIS ip camera using OpenCV

My following program can load mp4 video successfully. That means ffmpeg and necessary libraries are working fine.#include <iostream>

</iostream>When I tried to access the IP Camera as follow
cv::VideoCapture vcap("rtsp://root:pass@192.168.0.90/axis-media/media.amp?camera=1");I have the following error
GStreamer Plugin: Embedded video playback halted; module source reported: Could
not open resource for reading and writing.
OpenCV Error: Unspecified error (GStreamer: unable to start pipeline
) in cvCaptureFromCAM_GStreamer, file /home/Softwares/opencv/opencv/modules

cpp:818: error: (-2) GStreamer: unable to start pipeline
in function cvCaptureFromCAM_GStreamerUser is root and password is pass and ip 192.168.0.90 are all defaults.
My if config gave me
