dynamically update image in video stream using ffmpeg
1er mars 2021, par omega1I have the following ffmpeg command which works, but I would like image3.jpg to update every 30 seconds (image3.jpg changes every 30 seconds). I read that I needed to move the file from a .tmp file image3.jpg.tmp to image3.jpg but this is not working either.


The script places a few images on screen and takes an audio stream as its input and then outputs to a RMTP server, all works except image3.jpg only updates if I stop the ffmpeg command and restart it (which I cannot do as it is a live stream).


I'm also struggling with where to add a
drawtext
within thefilter_complex
section if anyone could help with that also ?

Thanks.

Faster Thumbnail/Image Extraction from Video using FFMPEG ?
17 juillet 2019, par Arif NadeemI am using this command to extract a series of images from a video to express them as a visual time-frame of the video.
ffmpeg -i inputfile.mp4 -r 1 -t 12 image-%d.jpeg
Most of my videos are in mp4 format. I am able to extract the images successfully but the time taken for extraction is too long.
Is there any way I could reduce the time for image extraction ?
EDIT : It is taking me 60 secs to get 8 thumbnails from a 15 sec long video encoded in MP4 format, I am doing this operation on my Galaxy Nexus(Android Phone) is there any way to improve the speed of operation, ideally I want it be less than 10secs.
