Hi, I want to capture video via a usb webcam. Using ffmpeg and
video4linux2, now I can easily record video.
Can you help me to record and play/show video in the screen using ffmpeg?
Can I control the position where to show the video in the screen?
I am using usb webcam and linux terminal.
Thanks
Hello,
I'm trying to use ffmpeg to stream from a Foscam FI8904 camera to an mp4
file. The camera only supports a jpeg or something stream via a CGI
(videostream.cgi). Output from wget:
Connecting to 192.168.0.123:80... connected.

Hi,
I often use the http client in ffmpeg from various websites and, most of
the time, it works fine.
However, in some instances the website doesn't allocate too much bandwidth
to a single connection and would benefit from using multiple simultaneous
http connections (i.e., the bandwidth is the b

Yes way!
If you take your answer out of context, among others by top-posting, I
have no idea what you're trying to say.
"No way", you're not trying to achieve anything?
"No way", you're not only using the first inut file? (You are,
no way.
$ ffmpeg -i 01.m4v -i 02.m4v -strict -2 03.m4v
2 input files. 01 and 02, and output to 03
I want to join 01 and 02.
Simple, no???
Please take a close look at my original message.

Stream all the time to UDP then record when I need.

Just to prove that it works after few times kill and start again.
I just dont get it why I have to do that, is because I quit the ffmpeg in a
strange way? Is this an issue of the ffmpeg? Hardware issues? I tried with
a different camera and the same happens.
ffmpeg.exe -y -f dshow -video_size 1920x

I was trying different examples where people were recording with the
blackmagic and that was one value, I could try without it and see if it
