FFMPEG command works on Mac but not on Windows [duplicate]
24 décembre 2019, par ArthurThis question is an exact duplicate of :
Hi I’m working on a project which needs to create animations by playing 2000 charts in 50 fps using FFMPEG, the command is :
ffmpeg -y -framerate 50 -i img-%04d.png -vb 40M -vcodec h264 esez.mp4charts are located in the same folder with name as img-0001.png img-2000.png
It worked well on my Mac. On Windows, the command can run and generate a mp4 file. But the animation is just black screen on Windows media player. I also tried open with VLC, it has some image, but not proper at all.
log from Windows CMD :

ffmpeg and libx264 videos do not play on video player
24 décembre 2019, par Tobifor a few months now I encountered a problem using
FFmpegin combination with the video codeh264. The video generation works fine and without any errors. I am using the following script since 2015 to build my videos from single pictures :#!/bin/bash
# ------------------------------------------------------------------------------
#
# Video generator
# Tobias Holzmann
# Date: 18.03.15
# Update: 24.12.2019
# Switch back to ffmpeg from avconv
#

vcodec="h264"
crf=18 # Between 0-51; 23 is default. 0 = lossless

-i animation.%4d.png \

# ------------------------------------------------------------------------------Today I made it a bit more fancy and easier to use. However, the problem is, that all videos I generate with
h264do not play at all using thevlcplayer or the common Ubuntu video player. I get errors such as :shorty@animation: vlc AVideo.flv
