Dumb ffmpeg question alert: What is a "pad" in the context of an "input pad", an "output pad" and a "filter pad"?
I understand the concept of padding a video with horizontal or vertical bars, padding audio with dead air or some other audio, but this is different. Is there a technical description of the actual term "pad" used to describe command line items in the ffmpeg execution string? There are a few references in the main ffmpeg documentation (https://ffmpeg.org/documentation.html) and a search of the ffmpeg-user archives brings many usages of the term, yet no actual description (385 hits: https://www.mail-archive.com/search?l=ffmpeg-user%40ffmpeg.org&q=+pad+). While I can infer the meaning, it would be great to get a meaningfully pedantic description from someone intheknow. On the interwebs I found this description: PAD [https://www.computerhope.com/jargon/p/pad.htm] Updated: 10/17/2017 by Computer Hope PAD may refer to any of the following: 1. When referring to a network, PAD, short for packet assembler/disassembler, is a device capable of converting from one packet into another. ...I presume this means to describe a device that converts packetized data from one packet format into another packet format while preserving the data [or information] contained within the original packet. ...This seems a little bit like converting a stream/file from one codec (e.g. h.264) into another (e.g. h.265) but that doesn't quite match the inference. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
