Good to know. Thanks.
Tell me, what's the difference between a decoder and a demuxer then?
a demuxer just unpacks serialized compressed data in stand-alone units
(avpackets) providing some additional context (timestamps and such)
a decoder takes a stand-alone unit (avpackets) and decodes it to a
raw/basic representation (frames containing pixels, audio samples)
in the specific case the image2 demuxer reads from the file system and
creates an avpacket for each image file.
The png/mjpeg/tiff/etc decoder takes the avpacket and decodes it to a
frame of raw pixels.
