How can I compress or change the resolution of the video very fast with FFmpeg ?
28 mai 2017, par RaresI would like to compress or change the resolution of the video before sending it to server but I don’t want to take too long. For example for the following code a video with size 100MB it takes 2-3 min to resize it to 10MB. Can I do it faster without losing too much quality ?

Create 1 video using image with length of audio
19 septembre 2017, par VishnuI am trying to create video with the length of an audio file , and 1 single image as the background for whole video.
I use following code
'ffmpeg -y -loop 1 -f image2 -r 24 -i subtitle.jpg -i audio.mp3 -c:v libx264 -c:a copy -shortest video.flv';But problem is processing time is too slow , and sometime video length is not same as audio length.Can some one suggest me alternative ideas.
p.s : audio length is just 3 to 8 seconds.
Below is my output

Blank video as the result of converting from bmp ffmpeg [duplicate]
1er juin 2021, par Артур Клочко

Update


I'm sorry, as I wrote I tried to play video via different variants and got nothing, but now I send it to myself via Telegram app, and it displays there correctly. It plays via Chrome also. Seems it is not the ffmpeg problem.


I uploaded it to my site, if you are not aware, please check it via stupid uwp app or Windows Media player if you are using Windows, and if you have the same problem, please feedback and I will report it as a bug





Recently I have been using ffmpeg to convert
jpgfile set tomp4, and it was successfully. I used the next.batfile to do it :

ffmpeg -framerate 60 -i out\%%d.jpg render.mp4


Now, I am trying to do the same, but with
bmpfiles, generated as screenshots using WinApi. Images as themselves are absolutely correct - I can open them via photos app, or anything else. Images resolution is constant and equals 2002x773.

So now I am using the same
.batto make video :

ffmpeg -framerate 60 -i out\%%d.bmp render.mp4


It generates a tiny-size video (17 kb, for 10 bmp images, 5 mb each), that is opening by UWP video app or Windows Media program, but nothing is happening - no errors, yet no video length. If there are more images, the result video size also increases, but the video still doesn't play.
