Re: [FFmpeg-user] Clipping off unwanted span of mp4 file

Possibly with lots of command-line hackery ffmpeg it might be able to do the job (extract segments and concat them together), but a real editor will make the job a lot easier. I've recently been using the shotcut editor (https://shotcut.org/), which is also opensource/free and uses some

Re: [FFmpeg-user] FFMpeg libvpx 1.7 support

Hello, I had these kind of compilation errors with previous version of Libvpx and Ffmpeg. Usually I had to manually delete the files related to the old version of libvpx from /usr/local/lib then to compile libvpx and finally ffmpeg. If you still have ffmpeg installed a "ldd

Re: [FFmpeg-user] He aac sampling rate and time stamps

[FFmpeg-user] Clipping off unwanted span of mp4 file

Hi all, I have an mp4 file that has unwanted span of video APPENDED to it. How do I delete that appended span? The appended span starts at 2 hours and 30 minutes and 53 seconds. Thanx!! ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org

[FFmpeg-user] Can I create an mp4 with dwell?

I'm a meteorologist making my own weather maps. I use ffmpeg to create my animations from still images, like this: http://45.79.86.175/output/nam/sfc/conus-nam-slp.mp4 Typically: ffmpeg -r 10 -f image2 -s 1920x1080 -start_number 02 -i /var/www/html/output/hrrr/sfc/ord-hrrr-slp%02d.png -y
