no command line options processing yet
open Exif header file
open JPEG header file
open circbuf and mmap it (once at startup)
find total buffer length (it is in defines, actually in c313a.h
Now open/mmap file to read sensor/compressor parameters (currently - just free memory in circbuf and compressor state)
open circbuf and mmap it (once at startup)
find total buffer length
create a named pipe always delete the pipe if it existed, start a fresh one
now should not exist
now open the pipe - will block until something will be written (or just open for writing Reads themselves will not block
Here is a main loop. If recording is on, it will check for commands after each frame, if it is off - poll with fixed usleep
look at command queue first
frame sent OK, nothing to do (TODO: check file length/duration)
just wait for the frame to appear at the current pointer
we'll wait for a frame, not to waste resources. But if the compressor is stopped this program will not respond to any commands TODO - add another wait with (short) timeout?
frame parameters have changed
next file needed (need to switch to a new file (time/size exceeded limit)
invalid frame pointer
frame broken (buffer overrun)
restart the file
error with file I/O
other errors
no commands in queue,starting (but not started yet)
retry starting
file started OK, nothing to do
just wait for the frame to appear at the current pointer
we'll wait for a frame, not to waste resources. But if the compressor is stopped this program will not respond to any commands TODO - add another wait with (short) timeout?
frame parameters have changed
invalid frame pointer
frame broken (buffer overrun)
it should be not too long so empty buffer will not be overrun
error with file I/O
other errors
not running, not starting
make it longer but interruptible by signals?
