I'm using HM 14.0 as a reference. Is there a way to get some specific information about NAL units like
(a) type
(b) num_bytes
(c) frame_no
(d) decode_time
(e) priority
(f) timestamp
The first two I can have it through annexBbytecount, but what about the rest?
The reference codec comes with a built in tracer which is quite powerful!
Enable it like this:
diff --git a/source/Lib/TLibCommon/TComRom.h b/source/Lib/TLibCommon/TComRom.h
index 5a59809..1930809 100644
--- a/source/Lib/TLibCommon/TComRom.h

As an example, I encoded and decoded the first 20 frames of BQMall_832x480_60.yuv
with trace enabled.
After encoding/decoding using:
./TAppEncoderStatic -c ../cfg/encoder_intra_main.cfg -c ../cfg/per-sequence/BQMall.cfg
./TAppDecoderStatic -b str.bin
trace-files are produced (rather huge ones!)

Have a look at TraceEnc.txt and TraceDec.txt they contain everything you need to know!
