Hi, Sorry to disturb you, I'm trying to extract only one image from a video. Using ffmpeg with Windows. It does work, but there is a warning I'd like to get rid of. Can anybody tell me the right syntax? Thank you very much! This is the syntax I'm currently using : *E:\tests>ffmpeg -i myvideo.mp4 -r 1 -ss 7 -frames:v 1 myvideo.jpg*
[...]
[image2 @ 00000273929beb40] *The specified filename 'myvideo.jpg' does not contain an image sequence pattern or a pattern is invalid.[image2 @ 00000273929beb40] Use a pattern such as %03d for an image sequence or use the -update option (with -frames:v 1 if needed) to write a single image.* frame= 1 fps=0.0 q=6.2 Lsize=N/A time=00:00:00.00 bitrate=N/A speed= 0x video:45kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown PS - If I use the -update option, it does not work at all.
Actually the correct syntax would be -update 1, not simply -update, it might not be evident for people not familiar with ffmpeg options. Maybe the warning message should be clarified.
