loggerd: switch to v4l encoder try 2 (#24380) * start v4l encoder * v4l encoder starts * start and stop * fill in proper controls * it dequeued a buffer * getting bytes * it made a video * it does make files * getting close * ahh, so that's how dequeue works * qcam works (no remuxing) * remuxing works * we just need to make shutdown and rollover graceful * graceful destruction * switch to polling * should work now * fix pc build * refactors, stop properly * touchups, remove a copy * add v4l encoder to release * inlcude file * move writing to it's own thread * fix minor memory leak * block instead of dropping frames * add counter, fix tests maybe * better debugging and test print * print file path in assert * format string in test * no more oversized qlogs * match qcam * touchups, remove omx encoder * remove omx include files * checked ioctl, better debugging, open by name * unused import * move linux includes to third_party/linux/include * simple encoderd * full packet * encoderd should be complete * lagging print * updates * name dq thread * subset idx * video file writing works * debug * potential bugfix * rotation works * iframe * keep writing support * ci should pass * loggerd, not encoderd * remote encoder code * support remote encoder * cereal to master, add encoderd * header no longer required * put that back there * realtime * lower decoder latency * don't use queue for VisionIpcBufExtra, disable realtime again * assert all written * hmm simpler * only push to to_write if we are writing * assert timestamp is right * use at and remove assert * revert to queue Co-authored-by: Comma Device <device@comma.ai> old-commit-hash: 0baa4c3e2ad9ee6f8daba8267db44c2cd44caa62
