MPEG2 is mostly patent-free too now, though I'm not sure how much larger its decoder would be.
- keithwinstein 7y agoThe core of libmpeg2 is 3,810 lines of C (not including any systems-stream demultiplexer or audio decoder) versus about 2,400 for pl_mpeg.h. So not dramatically larger. On the other hand, for progressive-scan 30fps video on computers without a VBV constraint and with a deterministic known decoder, I'm not sure any of the extra features in the MPEG-2 spec are very helpful compared with MPEG-1.
