✨ M2VRequantiser(1) ✨ — MPEG-2 streams requantization 🎀

okay bestie, the manual name is M2VRequantiser and it's all about MPEG-2 streams requantization 💖 so let's get into it 💅

👑 NAME

M2VRequantiser — MPEG-2 streams requantization 🦋

🌸 SYNOPSIS

Two ways to call it, bestie 🧚

M2VRequantiser
M2VRequantiser <RECOMPRESSION_FACTOR> <inputM2Vsize>

💜 DESCRIPTION

okay so m2vrequantiser is a tool that requantizes MPEG-2 streams without recompressing ✨ 😭 it's giving "bigger brain, same file" energy. M2VRequantiser takes raw MPEG-2 video data (not VOB) from standard input and writes the recompressed frames to standard output 🔥

and highkey, it's a good replacement for tcrequant, which is an obsolete utility that shipped with some versions of the transcode suite 💀 so if you're still using that, it's time for a glow-up 🫶

🎀 OPTIONS

okay so there aren't any options, bestie 🙈 the tool just takes two arguments and that's the whole vibe 💅

M2VRequantiser reads raw MPEG-2 video data (not VOB) from standard input and writes the recompressed frames to standard output 🌈

It takes two arguments 🍓

• First argument — a floating point value that sets the ratio of compression, aka RECOMPRESSION_FACTOR 💖
• Second argument — the size of the M2V, aka inputM2Vsize 🦋 and here's the tea: since the data is streamed in, M2VRequantiser cannot know the M2V size on its own, so you have to tell it ✨

The usage is:

$ M2VRequantiser <RECOMPRESSION_FACTOR> <inputM2Vsize>

🧚 EXAMPLE

the following command would recompress original.m2v, whose size is 1024000 bytes, by a factor of 1.25 🌸

$ M2VRequantiser 1.25 1024000 < original.m2v > requantised.m2v
