4 |
- * This file is placed in the public domain. Use the program however you |
|
5 |
- * see fit. |
|
6 |
- * |
|
7 |
- * This utility rearranges a Quicktime file such that the moov atom |
|
8 |
- * is in front of the data, thus facilitating network streaming. |
|
9 |
- * |
|
10 |
- * Compile this program using: |
|
11 |
- * make qt-faststart |
|
12 |
- * Invoke the program with: |
|
13 |
- * qt-faststart <infile.mov> <outfile.mov> |
|
14 |
- * |
|
15 |
- * Notes: Quicktime files can come in many configurations of top-level |
|
16 |
- * atoms. This utility stipulates that the very last atom in the file needs |
|
17 |
- * to be a moov atom. When given such a file, this utility will rearrange |
|
18 |
- * the top-level atoms by shifting the moov atom from the back of the file |
|
19 |
- * to the front, and patch the chunk offsets along the way. This utility |
|
20 |
- * presently only operates on uncompressed moov atoms. |

+ * qt-faststart.c, v0.1 |
|
2 |
+ * by Mike Melanson (melanson@pcisys.net) |
|
3 |
+ * This file is placed in the public domain. Use the program however you |
|
4 |
+ * see fit. |
|
5 |
+ * |
|
6 |
+ * This utility rearranges a Quicktime file such that the moov atom |
|
7 |
+ * is in front of the data, thus facilitating network streaming. |
|
8 |
+ * |
|
9 |
+ * Compile this program using: |
|
10 |
+ * make qt-faststart |
|
11 |
+ * Invoke the program with: |
|
12 |
+ * qt-faststart <infile.mov> <outfile.mov> |
|
13 |
+ * |
|
14 |
+ * Notes: Quicktime files can come in many configurations of top-level |
|
15 |
+ * atoms. This utility stipulates that the very last atom in the file needs |
|
16 |
+ * to be a moov atom. When given such a file, this utility will rearrange |
|
17 |
+ * the top-level atoms by shifting the moov atom from the back of the file |
|
18 |
+ * to the front, and patch the chunk offsets along the way. This utility |
|
19 |
+ * presently only operates on uncompressed moov atoms. |
