ffmpeg - Understand images to video output, players show different images and lengths
8 juillet 2023, par Matt CI'm using multiple images to create a video with each image on a 1-second long frame. This is the command I'm using :


ffmpeg -framerate 1 -i 'image%d.jpg' -c:v libx264 -r 1 -pix_fmt yuv420p out.mp4



This seems straightforward and exactly what many others have done with success. However, the output I get is an mp4 which windows file explorer says is 4 seconds long, and is different in VLC and Windows media player and neither is the desired output.


In Windows : the video plays for 4 seconds with a black screen and at this point the time line at the bottom is filled up at 4 seconds, indicating the video is over. But it keeps playing, for another 4 seconds. And the last 4 seconds (from 0:04 to 0:07) is actually the desired output.

In VLC : the video shows last image supplied as input for 3 seconds, followed by the second to last image for 1 second.

Questions :


- 

- How/Why are these different in different players ?
- Why, in VLC, are only two images showing up, and why would one of them last for 3 seconds ?
- In Windows, why/how is the video 8 seconds long but shows up as 4 seconds both in the file explorer and in the actual media player ?
- How do I get the desired output, and what caused my case to not work as it did for seemingly most others ?

Hide ffplay window and just show input video [closed]
5 mai 2023, par Scott WilkersonI'm using FFMPEG/FFPLAY to display video on a monitor from a Decklink card. After much research I finally found a good command to get the video displayed correctly, and at a specific location in the monitor with no border :


ffplay -f dshow -video_size 1280x720 -left 631 -top 19 -rtbufsize 702000k -framerate 59.94 -i video="Decklink Video Capture":audio="Decklink Audio Capture" -threads 2 -noborder


The problem is I need to ONLY display the borderless input video. NOT ffplay running. I figured out I could use -nostats to get rid of the video statistics, but not the command prompt window.


-nostdin DOESN'T WORK
-nodisp HIDES THE INPUT VIDEO, not the command prompt window.


Thanks in advance !
