Hello. Video filter 'colorspace' aborts with "Unsupported input primaries 2
(unknown)" with -f concat as input.
Is there a way to set/force those things between the filters 'scale' and
colorspace (or between input and the first filter) so that
colorspace works ?
In the examples below, bt470bg
I have a docker container which when run opens a URL using firefox which is
the input and stream it to an RTMP URL using FFMPEG FLV. here is the
Github project if anyone wants to test. Nice application.

Here is the ffmpeg code.

How can you programmatically tell? I don't know of an easy way.
(The other thing to do is not top-post on this mailing list.)

Hello
What do you do when audio is in sync (lip sync) at times and off at other
times ?
Thanks

Brilliant, thank you.

Hi,
if I invoke ffmpeg on an M2V MPEG-2 elementary stream, I get "N/A" for the
duration. I guess this is because this file doesn't contain a header that
contains the duration. Is it possible to force ffmpeg to parse the entire
file to obtain the duration?
Full command line and output:

Hello. I am hoping to produce a slideshow from a list of jpeg images.
I was anticipating bt709 output from scale, however the log appears to show
it's producing bt470bg with limited range, even though I
specify out_color_matrix=bt709 and out_range=full
Any suggestions would be very welcome.
Hi,
Trying to get a visualisation of my levels during record / stream.
This works fine for file based material:
ffplay -f lavfi -i
"amovie=/Users/bouke/Downloads/test.wav,ebur128=video=1:meter=18:target=-16
[out0][out1]"
But I would like to have a live source (I’m on Mac, AVfoundation I
"In your example all three inputs are images, so the output can be only one
image."-> this doesn;t happen.
The output consists in:
1. the original image
2. the original image + logo
3. the original image + logo + info
I wish it were simpler!

In your example all three inputs are images, so the output can only one
image.
If the first input is a video, you could add -ss 5 before this

Many thanks.
