# 🔎 naldump

Tool for parsing an H.264 or H.265 Network Abstraction Layer (NAL) Annex B
bytestream and printing the size and type of each NAL unit.

Input may be read from a file or standard input. If read from standard input,
the time (in seconds since start) is printed.

H.264 is assumed unless `-hevc` flag is specified. To exclude certain NAL
types, use `-exclude` flag. For instance, to exclude H.264 Supplemental
Enhancement Information (SEI) units, specify `-exclude 6`. To exclude more
than one type, use a comma-separated list.

## Example
```
$ cat myfifo | ./naldump -hevc
