How to create a Packet from memory about gmf HOT 2 OPEN

@russelltg Hi. See avio.go and there is a test in format_test.go TestAVIOContext and custom reader implementation customReader. Probably it helps.

from gmf.

I noticed an issue with this test, you never actually get any packets. You can reproduce this by putting a panic in this loop

for p := range ictx.GetNewPackets() {
  panic("")
  _ = p
  Release(p)
}

Weirdly this seems to work with raw h264 files, but not mp4 files.
