Hi,
I'm working on an program that is to receive CTF stream packets and convert the contained events to a different format. After reading through the babeltrace2 C API docs, I'm not sure if it's possible to access the internal AST and parser utilities used by the internal plugins, either manually or through a source component plugin. With a metadata text file at hand, is there a way to parse CTF stream packet sitting in memory? I'm trying to avoid having to write the in-memory packets to disk first, and then use the source.ctf.fs component class to read them back in as babeltrace2 API types. For context, I have a few micros instrumented with barectf. Depending on the deployment mode, I'm either sending CTF stream packets out over serial or reading a ring buffer of packets via JTAG. I can see this also being useful in a couple other dimensions I'd eventually like to consider too: * Implementing something lttng-relayd friendly for live viewer support (parsing some of the packet header fields) * Stream clock overflow bookkeeping (it'd let me reduce the probe effect of have to manage a 32 or 64 bit clock on a 16 bit MCU) Best, Jon
