  1. 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?

  2. 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.

    -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

    ffplay -i "video.mp4" -vf boxblur=10:10
    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.
