FFmpeg image to video conversion error : [image2] Opening file for reading
14 février 2018, par user1690179I am running ffmpeg on an AWS Lambda instance. The Lambda function takes an input image and transcodes it into a video segment using ffmpeg :
ffmpeg -loop 1 -i /tmp/photo-SNRUR7ZS13.jpg -c:v libx264 -t 7.00 -pix_fmt yuv420p -vf scale=1280x720 /tmp/output.mp4I am seeing inconsistent behavior where sometimes the output video is shorter than the specified duration. This happens inconsistently to random images. The same exact image sometimes renders correctly, and sometimes is cut short.
This behavior only happens on Lambda. I am not able to replicate this on my local computer, or on a dedicated EC2 instance with the same environment that runs on lambda.
I noticed that when the output video is short, the ffmpeg log is different. The main difference are repeated

...As requested, here is a link to the full log. In this log - ffmpeg renders only 323 out of 375 frames.
The

Access video stream from Cloud IP Camera
13 février 2018, par FergusonI have bought a new "cloud IP" camera and I don’t know If I can access video stream over RTSP or some other protocol from local computer ?
I would like to stream a video over VLC or FFMpeg program.
The model of camera is : CIPC-GC13H

Extract Video Frames In Python
28 février 2024, par TheNoneI want to extract video frames and save them as image.



import os, sys
from PIL import Image

a, b, c = os.popen3("ffmpeg -i test.avi")
out = c.read()
dp = out.index("Duration: ")
duration = out[dp+10:dp+out[dp:].index(",")]
hh, mm, ss = map(float, duration.split(":"))
total = (hh*60 + mm)*60 + ss
for i in xrange(9):
 t = (i + 1) * total / 10
 os.system("ffmpeg -i test.avi -ss %0.3fs frame%i.png" % (t, i))



But I have this error :

Supported file protocols:

Frame size, frame rate abbreviations:

Motion estimation methods:

Note, the names of encoders and decoders dont always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported for example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats its even
worse



What is wrong in my code ? Thanks in advance
