ffmpeg encode video produce incorrect mediainfo encoding settings
25 août 2021, par FoongI've been trying to do batch encode videos to H265 format. I am using media-autobuild_suite to build ffmpeg and have already updating ffmpeg to the latest version.

However, the Writing library and Encoding settings output is incorrect. Before update ffmpeg doesn't have this issue. I wonder what have been missing that causing this issue.

I have tried with simplest ffmpeg from official wedsite and encoding cli but the output still same.


ffmpeg -i "input.mkv" -c:v libx265 "output.mkv"



Update :
Tried converting video with FFmpeg 4.4 "Rao" from https://www.ffmpeg.org/ working fine. But compiled ffmpeg from media-autobuild_suite, tried with light build and full build, Writing library and Encoding settings output still incorrect.

ffmpeg video slides vertically after 'Invalid buffer size, packet size expected frame_size' error (vsync screen tearing glitch) ?
7 juillet 2020, par GlabbichRulzI have a video which i want to cut and crop using opencv and ffmpeg.




I want the output to be H265, so i am using a ffmpeg subprocess (writing frame bytes to stdin) as explained here. This is a minimum version of my code that leads to the error :


import os, shlex, subprocess, cv2, imutils

VIDEO_DIR = '../SoExample' # should contain a file 'in.mpg'
TIMESPAN = (3827, 3927) # cut to this timespan (frame numbers)
CROP = dict(min_x=560, max_x=731, min_y=232, max_y=418) # crop to this area

# calculate output video size
size = (CROP['max_x']-CROP['min_x'], CROP['max_y']-CROP['min_y']) # (w,h)
# ffmpeg throws an error when having odd dimensions that are not dividable by 2,
# so i just add a pixel to the size and stretch the original image by 1 pixel later.
size_rounded = (size[0]+1 if size[0] % 2 != 0 else size[0],
 size[1]+1 if size[1] % 2 != 0 else size[1])

# read input video
vid_path_in = os.path.join(VIDEO_DIR, 'in.mpg')
cap = cv2.VideoCapture(vid_path_in)
fps = int(cap.get(cv2.CAP_PROP_FPS))

# generate and run ffmpeg command
ffmpeg_cmd = (f'/usr/bin/ffmpeg -y -s {size_rounded[0]}x{size_rounded[1]} -pixel_format'
 + f' bgr24 -f rawvideo -r {fps} -re -i pipe: -vcodec libx265 -pix_fmt yuv420p'
 + f' -crf 24 -x265-params "ctu=64" "{os.path.join(VIDEO_DIR, "out.mp4")}"')
print("using cmd", ffmpeg_cmd)
process = subprocess.Popen(shlex.split(ffmpeg_cmd), stdin=subprocess.PIPE)

# seek to the beginning of the cutting timespan and loop through frames of input video
cap.set(cv2.CAP_PROP_POS_FRAMES, TIMESPAN[0])
frame_returned = True
while cap.isOpened() and frame_returned:
 frame_returned, frame = cap.read()
 frame_number = cap.get(cv2.CAP_PROP_POS_FRAMES) - 1

 # check if timespan end is not reached yet
 if frame_number < TIMESPAN[1]:

 # crop to relevant image area
 frame_cropped = frame[CROP['min_y']:CROP['max_y'],
 CROP['min_x']:CROP['max_x']]

 # resize to even frame size if needed:
 if size != size_rounded:
 frame_cropped = imutils.resize(frame_cropped, width=size_rounded[0],
 height=size_rounded[1])

 # Show processed image using opencv: I see no errors here.
 cv2.imshow('Frame', frame_cropped)

 # Write cropped video frame to input stream of ffmpeg sub-process.
 process.stdin.write(frame_cropped.tobytes())
 else:
 break

 # Press Q on keyboard to exit earlier
 if cv2.waitKey(25) & 0xFF == ord('q'):
 break

process.stdin.close() # Close and flush stdin
process.wait() # Wait for sub-process to finish
process.terminate() # Terminate the sub-process

print("Done!")



Unfortunately, my output looks like this :




The output should not include this vertical sliding glitch. Does anyone know how to fix it ?


My console output for aboves script shows :

As you can see, there is an error :
Invalid buffer size, packet size 51600 < expected frame_size 95976 Error while decoding stream #0:0: Invalid argument
, do you think this could be the cause to the shown problem ? I am not sure, as in the end, it tells me all 100 frames would have been encoded.

In case you want to reproduce this on the exact same video, you can find
actions1.mpg
in the UCF Aerial Action Dataset.

I would greatly appreciate any help as i am really stuck on this error.
