HLS. FFmpeg : error when loading first segment [closed]
30 avril 2024, par rus_99_pkI'm trying to download a streaming video using ffmpeg. There is a file in the format *.m3u8. BUT, if everything was so simple, I would not have come here.


There are a number of nuances :


- 

- It cannot be downloaded by specifying a link to the file
- If you upload the file and look at its contents, there will be :
#EXT-X-KEY:METHOD=AES-128,URI="[KEY],IV=[IV]






With a URI, the task is easy to solve ; just specify the value list.m3u8.


I end up getting :


Error when loading first segment 'https://cdnv-m12.boomstream.com/vod/hash:21596def3216ed982660d609751b8078/id:35105.29443.1039983.85853232.150106.hls/time:0/data:eyJ2ZXJzaW9uIjoiMS4yLjk3IiwidXNlX2RpcmVjdF9saW5rcyI6InllcyIsImlzX2VuY3J5cHQiOiJ5ZXMifQ==/m61/2024/04/27/1Q0idCxb.mp4/media-1.ts'


But with IV it’s more difficult, because file processing is performed on the server side. Please help.


I tried to get JS with similar variable names and monitor network traffic using Wireshark, in the hope of catching a response from the server with IV.


But it didn't help me.


My script for download :

ffmpeg output with label 'v' does not exist in any defined filtler graph
15 avril 2024, par David RoyaleBeen trying to make this Python code work but it fails up until rendering the final part :


import subprocess
import re
import os

def detect_idle_sections(video_path):
 command = ['ffmpeg', '-i', video_path, '-vf', 'select=\'gt(scene,0.1)\'', '-vsync', 'vfr', '-f', 'null', '-']
 output = subprocess.check_output(command, stderr=subprocess.STDOUT).decode('utf-8')
 
 idle_sections = []
 duration = 0.0
 for line in output.split('\n'):
 match = re.search(r'scene:(\d+)', line)
 if match:
 scene = int(match.group(1))
 if scene == 0:
 duration += 1.0 / 30 # Assuming 30 fps
 else:
 if duration > 0:
 idle_sections.append((duration, duration - (1.0 / 30))) # Duration and start time
 duration = 0.0
 
 return idle_sections

def cut_idle_sections(video_path, idle_sections, output_path, total_duration):
 print("starting to cut things")
 filters = []
 start_time = 0.0
 for duration, _ in idle_sections:
 filters.append(f'[0:v]trim=start={start_time}:end={start_time + duration},setpts=PTS-STARTPTS[v{len(filters)}]')
 start_time += duration
 
 if start_time < total_duration:
 filters.append(f'[0:v]trim=start={start_time},setpts=PTS-STARTPTS[v{len(filters)}]')

 filter_str = ';'.join(filters)
 print("finished chopping")
 command = ['ffmpeg', '-i', video_path, '-filter_complex', filter_str, '-map', '[v]', output_path]
 subprocess.call(command)

def get_total_duration(video_path):
 print("prior getting time")
 command = ['ffprobe', '-v', 'error', '-show_entries', 'format=duration', '-of', 'default=noprint_wrappers=1:nokey=1', video_path]
 output = subprocess.check_output(command).decode('utf-8').strip()
 print("after getting time")
 return float(output)

input_file = r"C:\Users\D\Videos\2024-04-15 08-42-53.mkv"
output_file = r"C:\Users\D\Videos\output_video.mp4"

# Get full paths
input_path = os.path.abspath(input_file)
output_path = os.path.abspath(output_file)

total_duration = get_total_duration(input_path)
idle_sections = detect_idle_sections(input_path)
cut_idle_sections(input_path, idle_sections, output_path, total_duration)


The error I am getting is :


[out#0/mp4 @ 000001af60f9d3c0] Output with label 'v' does not exist in any defined filter graph, or was already used elsewhere.
Error opening output file C:\Users\D_era\Videos\output_video.mp4.
Error opening output files: Invalid argument


The code is intended to cut "iddle" frames where frame a = frame b. I want to point out that I don't really care about audio, so it's just comparing if frames "A" through "H" are the same and keeping a and continuing with the rest of the video.


Putting some comments to determine which part was successful and which broke, I found that the line failig is this :


command = ['ffmpeg', '-i', video_path, '-filter_complex', filter_str, '-map', '[v]', output_path]


and apparently is the -map part.

Flutter error in Ffmpeg, "Unhandled Exception : ProcessException : No such file or directory" in macOS desktop version
19 avril 2024, par pratik vekariyaI'm trying video trim video using ffmpeg, for macOS desktop application.


I have downloaded ffmpeg from here for macOS.


Here is my code


String mainPath = 'Users/apple/Workspace/User/2024/Project/videoapp/build/macos/Build/Products/Debug/';
 mainPath = mainPath.substring(0, mainPath.lastIndexOf("/"));
 
 Directory directoryExe3 = Directory("$mainPath");
 var dbPath = path.join(directoryExe3.path,
 "App.framework/Resources/flutter_assets/assets/ffmpeg/ffmpegmacos");
//here in "Products/Debug/" folder desktop app will generate

//directoryExe3 path will be, Users/apple/Workspace/User/2024/Project/videoapp/build/macos/Build/Products/Debug

//and dbPath will be, Users/apple/Workspace/User/2024/Project/videoapp/build/macos/Build/Products/Debug/App.framework/Resources/flutter_assets/assets/ffmpeg/ffmpegmacos

//so when app will run it can access it from this path

//executable code, command for ffmpeg

String transpose_str += "crop=" +
 out_w.toInt().toString() +
 ":" +
 out_h.toInt().toString() +
 ":" +
 x!.toInt().toString() +
 ":" +
 y!.toInt().toString() +
 ",";
 transpose_str += "scale=960:192";

Future<processresult> result_ = Process.run(dbPath, [
 "-ss",
 timestamp,
 "-i",
 inputFilePath,
 "-t",
 endTime,
 "-vf",
 transpose_str,
 "-an",
 "./temp.mp4",
 ]); 
</processresult>

Now when I run this in macOS desktop verison, it gives me error at Process.run that in dbPath, Unhandled Exception : ProcessException : No such file or directory.


Any help would be appreciate !


when i run this as desktop version it should get file from assets.
