I have a video file and I want to get the list of streams from it. I can see the needed result by for example executing a simple `ffprobe video.mp4:
....
Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661) ......
Stream #0:1(eng): Audio: aac (LC) (mp4a / 0x6134706D), ......
....
But I need to use python and code that will work both on Windows and Ubuntu, without executing an external process .
My real goal is to check whether there is ANY audio stream within the video (a simple yes/no would suffice), but I think getting extra information can be helpful for my problem, so I'm asking about the entire streams
EDIT: Clarifying that I need to avoid executing some external process, but looking for some python code/library to do it within the process.
import os
import json
import subprocess
file_path = os.listdir("path to your videos folder")
audio_flag = False
for file in file_path:
ffprobe_cmd = "ffprobe -hide_banner -show_streams -print_format json "+file
process = subprocess.Popen(ffprobe_cmd,stdout=subprocess.PIPE,stderr=subprocess.PIPE, shell=True)
output = json.loads(process.communicate()[0])
for stream in output["streams"]:
if(stream['codec_type'] == 'audio'):
audio_flag = True
break;
if(audio_flag):
print("audio present in the file")
else:
print("audio not present in the file")
# loop through the output streams for more detailed output
for stream in output["streams"]:
for k,v in stream.items():
print(k, ":", v)
Note: Make sure that your videos folder path consist of only valid video files as i didn't include any file validation in the above code snippet. Also, I have tested this code for a video file that contains one video stream and one audio stream.
