    28 novembre 2015, par ComeBack

  • Could a compression algorithm be lossless and lossy at the same time ?

    4 avril 2019, par Pasta Fresca

    I have seen ffmpeg has some codecs (e.g. H.264) which are defined as lossless and lossy at the same time, and from my understanding, lossless and lossy are mutually exclusive : a compression algorithm either losses information or doesn’t.

    How is it possible to be lossless and lossy at the same time ?

    Running ffmpeg -codecs 2>/dev/null| grep h264, I get :

    DEV.LS h264                 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 [...]

    DEV.LS stands for Decoder, Encoder, Video, Not only intraframe compression, Lossy compression, Lossless compression.
