Unable to extract KLV data from .mpg file
2 novembre 2023, par Arjun ShastryI need to extract the klv data embedded in the following file :
https://samples.ffmpeg.org/MPEG2/mpegts-klv/Day%20Flight.mpg


Currently, I am doing it using ffmpeg and python.
The code works for .ts files like the example given below, but not the above mpg file. :
https://www.arcgis.com/home/item.html?id=55ec6f32d5e342fcbfba376ca2cc409a


I used the following python command, using subprocess, ffmpeg to extract klv data in a binary file and then using klvdata library to tranlate to a readable text file.


#Extract klv data and output as binary file
command=['ffmpeg', '-i', input_video, '-map', 'd','-codec','copy','-f', 'data','out.bin']
process=subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = process.communicate()

print(stdout)
print(stderr)

#Open text file to write json data
outjson=open("./outjson.txt","w")
print("Flag 1")

# Open the out.bin file for reading as binary
with open("./out.bin", "rb") as f:
 sample=[]
 cnt=0
 for packet in klvdata.streamparser.StreamParser(f):
 pack=[]
 metadata = packet.MetadataList()
 for i in (5,6,7,13,14,15,18,19,23,24,25,26,27,28,29,30,31,32,33):#Only extracting required data
 pack.append(metadata[i][-1])
 sample.append(pack)
 sampleLength=(len(sample))
 json.dump(sample,outjson,indent=4) # Convert the metadata to a string and write it to outtext.txt


When doing it for "Day Flight.mpg", the following error occurs :

MoviePy error: FFMPEG encountered the following error while writing file rendus_finaux/output.mp4:

 b'rendus_finaux/output.mp4: No such file or directory\r\n'
</module>

It tried different versions of
moviepy, Python and reinstallingffmpegetc, but couldn't solve it. My main idea is that is a version problem, but i can't find out.

I recreated the error with this mre, it's just a code to make a video from multiple images. Thank you for your help.


from moviepy.editor import ImageClip, CompositeVideoClip, concatenate_videoclips
 
 DURATION_PER_IMAGE = 5
 
 images = ["D:/videos/image1.png","D:/videos/image1.jpg"]
 
 clips = []
 for image in images:
 #Main image
 clip = ImageClip(image).set_duration(DURATION_PER_IMAGE).resize(width=1080)
 clip = clip.resize(lambda t : 1+0.02*t)
 
 #Create clip composite
 clip_composite = CompositeVideoClip([clip.set_position("center")], size=(1080,1920))
 clips.append(clip_composite) # Add created clip to the list of clips
 
 clip_final = concatenate_videoclips(clips)
 clip_final.write_videofile(f"rendus_finaux/output.mp4", fps=24)
