Merge videos with different start times and show them on a grid
1er août 2017, par shamaleyteI have multiple video files of a conference call. However, each participant joined the call at a different time, which resulted in the fact that each video file has a different start time offset values.
Video Start Time
------------------
Video1 00:00
Video2 00:10
Video3 01:40My purpose is to play back this conference. However, I did not record the conference as 1 video, it is recorded with multiple video files, instead.
How do I stitch these videos ?There is also a paid solution to merge video fragments to a single clip – this will make the client-side much simpler. But can I do it for free ?
The expected outcome is to have one video showing three videos on a grid.
When ffmpeg stitches the videos, it should consider their start time values properly so that the videos are played accordingly. -
Can anyone tell me ffmpeg.wasm command to converting 24-bit color image to 8-bit color image without affecting transparency part ?
4 avril 2024, par Rohit NayakI am a new developer and currently developing a png compressor to compress png image file using next.js 14 app directory and I found the right command to do so


ffmpeg -i input.png -c:v png -pix_fmt pal8 -vf "split[a][b];[a]alphaextract[am];[b]palettegen=stats_mode=diff[pl];[b][pl]alphamerge" output.png



but i am unable to do so because I don't know how to convert that to ffmpeg.wash command.


I am using node.js v20.11.0, @ffmpeg/ffmpeg version 0.12.6 and @ffmpeg/util 0.12.1", alone with @ffmpeg/core@ version 0.12.2 which seems to work well.


My code is as following :


ffmpeg.exec([
 "-i",
 `${file.name}`,
 "-c:v",
 "png",
 "-pix_fmt",
 "pal8",
 "-vf",
 "split[a][b];",
 "[a]alphaextract[am];",
 "[b]palettegen=stats_mode=diff[pl];",
 "[b][pl]paletteuse=new=1:alpha_threshold=128",
 `output.png`,
 ]);



Is there anyone who can solve this problem ?
An early action will highly be appreciated😊


Answer in the form of


ffmpeg.exec([...commands ])

FFMPEG : How To Break steam and Retry Again Automatically
8 décembre 2019, par VarunThe Live Stream is in
m3u8
format
I am Usingyoutube-dl
with--no-part
to record the video.The problem is that I can’t watch the video while it’s recording. I need to Stop Recording with Ctrl+C to watch the recorded video.
So I am thinking if there could be a python script with a loop that will break the live stream on every 1 hr of recording automatically and run the same code again with the different filename in output.
In this way, I will get a recording of every one hr separately.
