I think this is likely to have something to do with it, but the options as shown are rejected by both ffplay and ffmpeg, and I'm not sure how to go about reading the docs to work out what I need to change. There are several complaints from ffplay, some more grumpy than others. - it says there's no such option as -r, but if I change it to -framerate, that part is happy in ffplay, but still doesn't work in ffmpeg - ffplay it says -s and -pix_fmt are deprecated and should be -video_size and -pixel_format respectively. However, those options are not offered at all in ffmpeg - but the kicker is that after those reports both ffplay and ffmpeg say "option pixel_format not found" and crash out. I poked around in the docs a bit, and found -pix_fmt, which seemed to say it's deprecated in favor of "private options" in ffplay, but seems like it should be good in ffmpeg. But... well, they're all being rejected. Are these options specific to individual "-f" types? That is, is there a chance that I need something specific (or worse, not offered by) decklink? _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
