Play mov 29.97 to 25 with Decklink board

Postby barabba2005 » Fri Aug 04, 2017 8:24 am

I'm trying to play with decklink board a .mov file with 29.978 FPS.
The decklink output is set to to 25 FPS with this script:

ffmpeg -r 25 -i 816.mov -pix_fmt uyvy422 -r 25 -vf scale=1920x1080 -c:a pcm_s16le -ar 48000 -ac 2 -filter:a "atempo=0.8" -f decklink "DeckLink Studio 2"

the problem is audio setting, i'm using atempo flag, but i dont know the correct value
If i dont play audio with -an flag, video is ok.

with audio i have this message:

Play start correctly but after some minutes give me an error:
[decklink @ 000000000298d400] There are not enough buffered video frames. Video may misbehave!

thank in advace
