Я намагаюся перетворити фільм mp4, знятий галактикою s5, у dvnxhd, але без успіху.
Ось моя команда:
ffmpeg -i "/media/elomin/20170805_221129.mp4"
-map 0:0 -map 0:1 -threads 4 -aspect 16:9 -y
-f mov -acodec pcm_s16le -b:a 256k -ar 48000
-ac 2 -b:v 45000k -r 30.00 -vcodec dnxhd

Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
що тут не так? Або не можливо перетворити оригінал. відео в такому форматі?
