ffplay exact examples of how to use.


where can i find detailed documents on how to use it?

when i just type

ffplay 1.mp4

it works

but

ffplay -vcodec prores -acodec pcm_s16le 1.mp4




gives error code

failed to set value 'prores' for option 'vcodec': option not found


what am i doing wrong?

ffplay isn't as easy to use as other video players, but it does have documentation (ex: try ffplay -h, probably with |More ).
https://ffmpeg.org/ffplay.html


the general syntax for video filters goes like this:
ffplay -i "video.mp4" -vf boxblur=10:10

Use ffplay -h to see the help. Use ffplay -codecs to see the available codecs.

ffplay -vcodec prores -acodec pcm_s16le 1.mp4

-vcodec prores means you are encoding with prores

But ffplay is a player (it does not encode) . You would use ffmpeg, not ffplay for encoding

so you can only apply filters ?

i thought you could use it to see what the video would look like when trans coded to another codec.
