Hi Dimitri, After talking with Philippe (Babeltrace 2's main contributor), this is not a bug in the CTF metadata parser. According to [1]: If the packet size field is missing, the whole stream only contains a single packet. So when if you don't have a packet header/context at all, the trace is considered to have a single big packet. That's why the metadata parser always create streams with packets. But the suggestion of adding timestamps to your packet is still valid.
