It shouldn't, because you forgot a "-" after "-f nut". > But I don't know what's the meaning of the - character after ffplay. Input or output. An url or a file-path. And in this case; stdout and stdin. FFmpeg's stdout is piped to FFplay's stdin. I'm surprised you didn't know. -- Reino _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
