<h2>Usage</h2>

|

This utility attempts to repair .sdriq files that have their header corrupted or with a pre version 4.2.1 header. Since version 4.2.1 a CRC32 checksum is present and the file will not be played if the check of the header content against the CRC32 fails.

This utility attempts to repair .sdriq files, that have their header corrupted, or were created using old versions of SDRangel. Since version 4.2.1 a CRC32 checksum is present and the file will not be played if the check of the header content against the CRC32 fails. In version 6.16.2 the timestamp resolution was increased from seconds to milliseconds since 1970-01-01 00:00:00.000.

You need to specify an input file. If no output file is specified the current header values are printed to the console and the program exits:

||||
|
||||
- -in string
|
||||
input file (default "foo")
|
||||
input file (default "foo")
|
||||
|
||||
To convert to a new file you need to specify the output file:
|
||||
|
||||
- -out string
|
||||
output file (default "foo")
|
||||
output file (default "foo")
|
||||
|
||||
You can specify a block size in multiples of 4k for the copy. Large blocks will yield a faster copy but a larger output file. With the default of 1 (4k) the copy does not take much time anyway:

||||
- -bz uint
|
||||
Copy block size in multiple of 4k (default 1)
