Re: [FFmpeg-user] ADD REAL TIME STAMP TO RTSP STREAM SEGMENT
I've been using Python to archive my RTSP IP camera footage. This is the
Python code I use to name the file the current date and time. Basically I
have the program terminate and start a new ffmpeg instance every 20
minutes. It would be nice though if ffmpeg could segment and timestamp the
files itself. Not sure how you would do that exactly.
timestr = time.strftime("%Y%m%d-%H%M%S")
myUrl='ffmpeg1rec -rtsp_transport tcp -y -rtbufsize 200M -i \"rtsp://
admin:password@192.168.1.23:554/Streaming/Channels/101/\" -f lavfi -f dshow
-i audio="virtual-audio-capturer" -c:a libmp3lame -ab 192k -ar 48000
-map_channel 1.0.0 -bufsize 5096k -c:v copy -f flv recordings/cam1-' +
timestr + '.mp4'
subprocess.Popen(myUrl, shell=True)

Re: [FFmpeg-user] ADD REAL TIME STAMP TO RTSP STREAM SEGMENT
Nevermind I just read your question again and I guess it sounds like you
want the time stamp from the camera itself. Not sure how you would do that.

[FFmpeg-user] V360 filter
Hi all, I see the progress on the V360 filter... that's very good! A few suggestions for improvement: -- (Single-)Fisheye as input and output format, with a selectable field of view up to 360° (little planet). -- A "color" option for filling those areas that have got no data from the input. -- I think the d_flip parameter needs some more documentation. What's an "in-depth" flip?
