Step 2: Dump lock flags from a frame cache file
For the initialization and running the pipeline, please refer step1
- Here only the pipeline description part is shown
- Access frame cache file by specifying frame_cache and instrument(=K1)
Toggle line numbers
1 instrument = 'K1'
2 src = pp.mklalcachesrc(pipeline, location = frame_cache, cache_dsc_regex = instrument)
- Define a demultiplexer(demux) to extract data in channel_list
Toggle line numbers
1 channel_list = []
2 headkeys = []
3 head_dict = {}
4 channel_list.append((instrument, 'GRD-LSC_MICH_STATE_N'))
5 demux = pp.mkframecppchanneldemux(pipeline, src, do_file_checksum = do_file_checksum, skip_bad_files = skip_bad_files, channel_list = map("%s:%s".__mod__, channel_list))
- Get channel data into head_dict
Toggle line numbers
1 headkeys.append("FLG")
2 for key, chan in zip(headkeys, channel_list):
3 head_dict[key] = cp.hook_up(pipeline, demux, chan[1],instrument, buf_length)
- Define a caps by specifying sampling rate(channel_rate) and resample rate(out_rate)
Toggle line numbers
1 caps = "audio/x-raw, format=F64LE, rate=%d" % int(channel_rate)
2 capsr = "audio/x-raw, format=F64LE, rate=%d" % int(out_rate)
3 for key in headkeys:
4 head_dict[key] = cp.caps_and_progress(pipeline, head_dict[key], caps, key)
5 head_dict[key] = cp.mkresample(pipeline, head_dict[key], 0, False, capsr)
- Dump the lock flag into a specified file(output)
Toggle line numbers
1 pp.mknxydumpsink(pipeline, head_dict["FLG"], output)
- The python script is available at git repository

- (Optional) After running on all the (or many of) frame files in phase-1 run (12087* ~ 12096*), you can generate frame cache files based on the lock flag
