Hi folks. I’ve created a list of small clips in random order, each with a
unique filename. This file is used for a concat input file.
In the verbose processing, I get lots of these after a few of the first files
are processed:
Error while decoding stream #0:0: Invalid data found when proces
Thank you so much ! I'd like to have a try !

We can't help with scripting on this mailing list: only unscripted usage of the
FFmpeg cli tools is supported here.

Hi!
I'm trying to detect duplication of video frames in live streams. Such
situation occurs when encoder can't encode stream at specified fps. I see
few frames with the same pkt_size. I know that there is filter to detect
similar frames but such technique looks like overkill.
The simplest solutio
Can you help, please? I need to find a way to auto convert an mp3 or wav
file to short video through the backend when someone hits a button on the
front end. And then it be linked to a share on social media. is
this possible? Can ffmpeg help do this?

Hi *,
ffprobe can nowadays produce JSON output, which is quite convenient
sometimes. I am trying to use that feature in order to get the output
of volumedetect as JSON. I tried the following:
ffprobe -loglevel error -of json=c=1 -show_entries root -f lavfi
-i 'movie=filename=clip.mkv:streams=
I recently did just this. frame->data[3] holds a CVPixelBufferRef. Here is some
sample code in Swift:
let pixelBuffer =
Unmanaged.fromOpaque(frame!.pointee.data.3!)
.retain()
.takeRetainedValue()
In C, you would do something like:
CVPixelBufferRef pixelBuffer =
CVPixelBufferReta

I have an mpeg2 file which I am trying to convert to a dvd iso.
I am using dvdauthor to do it.
dvdauthor says the file is not mpeg2 video compatible.
When I run ffprobe on the file, I get this

oh no, I don't want to learn a new command line syntax only to solve
this simple problem.
I have a long ffmpeg command line that's working fine when writing the
output to a file. Is there really no easy way to send the output to the
speakers instead?
It is very easy syntax to learn, you can sen
