Hello ffmpegs,
I hope I have come to the right place. I've got a problem concatenating
webcam videos through an automatically generated filter chain.
The idea is to combine a series of webcam videos from a webconference,
filling the gaps between webcam videos with still images.
The still
I Think I am doing this correct, but I get an error. I have recovered some
videos from a mac that crashed and can’t be helped… they are .mov files and
look like they have a lot of data in them. several gig on each one… I have
tried several unpaid and paid programs that use and don’t use some

ffprobe will report a lot of info about a video file; I find MediaInfo to be
useful for that, too.
With that, you -may- be able to tell

Data recovery is always uncertain, whether from a single file or from a hard
drive- if you can't find some indicator of what's where, it's all just
random data (this is why

Hi all,
I've been working with a Decklink Quad HDMI card under Ubuntu 20.04. The
kernel driver is loaded and the Blackmagic software "mediaexpress" displays
the input signal perfectly. However, when I try to use ffplay, it seems
like it knows which of the four channels on the card has a signal,
I think I have determined that as far as ffmpeg is concerned there is no
input. I added the flag -color_bars false, which I believe tells ffmpeg not
to display color bars in response to lost input. Sure enough, the color bars
went away. I interpret this as telling me that there was no signal, as
10 matches
