Yes, it is similar, since ffmpeg expects the unix domain socket input to
be seekable, hence why it attempts to read the beginning of the file
twice, without taking into account that it is a consumable stream of data.
I created a fix but I can't figure out how to mail the patch without the
mailing server messing up the format. Setting `is_streamed` to true in the
URLContext fixes unix domain socket inputs.
