I think the error message is explicit enough here. You're trying to apply the option pix_fmt to an input file. Simply remove it (or move it after your inputs and before your output if required) and it should work (at least here it does). _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
