Subprocess doesn't return expected result
8 avril 2023, par Gren ManSubprocess doesn't return expected result


I have been trying getting info from video files using ffprobe


But I stumbled upon unexpected results, here are some test I've done


First test


# ffprobe -v error -select_streams v:0 -show_entries stream=height,width -of csv=s=x:p=0 
proc = subprocess.Popen(['ffprobe', '-v', 'error', '-select_streams', 'v:0', '-show_entries', 
 'stream=height,width', '-of', 'csv=s=x:p=0 ', video_path],
 stdout=subprocess.PIPE, stdin=subprocess.PIPE)

# proc.stdout.read() Returns b'widthXheightt\r\n'
v_resolution = proc.stdout.read().decode('utf-8').replace('\r', '').replace('\n', '')
# Result 'widthXheight'



First test was successful.


Second test


# ffprobe -v error -select_streams v:0 -show_entries stream=display_aspect_ratio -of default=noprint_wrappers=1:nokey=1
proc = subprocess.Popen(['ffprobe', '-v', 'error', '-select_streams', 'v:0', '-show_entries',
 'stream=display_aspect_ratio','-of default=noprint_wrappers=1:nokey=1', video_path],
 stdout=subprocess.PIPE, stdin=subprocess.PIPE)

# proc.stdout.read() Returns b''
a_r = proc.stdout.read().decode('utf-8').replace('\r', '').replace('\n', '')
# Result ''



Hmm, this doesn't sounds right I thought result should be e.g. 16:9


I tried putting code to CMD which returned aforementioned result


Third test


# ffprobe -v error -select_streams v -of default=noprint_wrappers=1:nokey=1 -show_entries stream=r_frame_rate
proc = subprocess.Popen(['ffprobe', '-v', 'error', '-select_streams', 'v', '-of',
 'default=noprint_wrappers=1:nokey=1','-show_entries', 'stream=r_frame_rate',
 video_path], stdout=subprocess.PIPE, stdin=subprocess.PIPE)

# proc.stdout.read() Returns b'30/1'
fps = proc.stdout.read().decode('utf-8').replace('\r', '').replace('\n', '') + ' fps'
# Result 30/1 fps



Just as expected this returned subarashi result


But what happened in a second test ? Can somebody explain it to me ? I used stderr which returned :


Failed to set value 'foo.mp4' for option 'of default=noprint_wrappers=1:nokey=1': Option not found



Result of python code

change brew install directory
23 juin 2018, par Addison WuI used homebrew to install ffmpeg and it’s by default in /usr/local/Cellar.
I have to run a matlab code, which tries to read ffmpeg from /usr/local/bin and returns error.Is there any way for me to change the path for brew install of ffmpeg ?
