FFMPEG:Invalid buffer size when converting video
30 juillet 2022, par Sar sinuaI'm trying to Pipe bytes in to FFMPEG in python and I've faced a problem.


import subprocess
from io import BytesIO

with open('input.mp4', 'rb') as f:
 input_byte=f.read()
command='ffmpeg -y -f rawvideo -video_size 320x240 -pixel_format yuv420p -framerate 15 -i pipe:0 -codec:a copy out.mp4'
process = subprocess.Popen(command, stdin=subprocess.PIPE, shell=True)

process.stdin.write(input_byte)
process.stdin.close()



The error I get is
Invalid buffer size, packet size 63420 < expected frame_size 115200 Error while decoding stream #0:0: Invalid argument


You can download the video from here.

Why A .FLAC File Converted by FFMPEG Cause File Explorer Unresponse on Windows 10 [closed]
20 juillet 2022, par Alex KingMy File Explorer Always showing "Working on it."
I've tried many resolutions.
First,I disconnect my NAS drive. seems fine.
I test many times on diffirient windows 10/11 versions.
I thought it was SMB problem on windows. But i was wrong.


Today I'm using FFMPEG convert .wav to .flac.


.\ffmpeg.exe -i $Source -c:a flac $Dest 



Just simple like this. Blow my computer up.


Even worse, explorer.exe crash after I'm trying to open FF output folder.


It's not the poblem from "Quick access" or "Search Index".


I'm now 100% percent confirm the flac files that ffmpeg made will cause file explorer crash.


I can't solve it without knowing the reason.


Might related to audio file tag vorbis ?


This is my FFMPEG info

PyAV/ffmpeg : How to resolve 'Reinit context to WxH ... deprecated pixel format'
26 mai 2023, par hi im BaconI am using the
pyav
library to read and process video data and as I am reading through the videos I am getting lots (and lots) of the following output.

I am creating the videos by segmenting either a much larger source file or RTSP/HTTP IP camera.


I would love to understand what this output actually means, and what I can do to prevent its output
