|
* "implicit" timecodes within DV-files and HDV-files etc.)

|
|
*
|
|
* the binary(!) position, where we have to seek into the file *and*
|
|
* the continuous frame number (ignoring the holes) starting from the
|
|
* beginning of the file, so that we know, which proxy frame to serve.
|
|
*
|
|
* This index has to be only built once for a file and is written into
|
|
* the BL_proxy directory structure for later reuse in different blender files.
