some early implementations of mpeg-1 compressors only supported I frames. amusingly, this is still a valid mpeg-1 bitstream.

- lmm 4y agoNot particularly strange, a lot of compression formats work like that. E.g. you can make a zip file at STORE level and there will be no actual compression.
- Am4TIfIsER0ppos 4y agoYou can do the same with a modern encoder too by setting the keyframe interval to 1 and "amusingly" the bitstream is still valid.
