rtmpdump's download result doesnt need any fixing. But in case you REALLY want to fix some random FLV-file, before you do so, you might want to analyze it with FLVExtract, Jaksta
's Fix FLV, and/or other tools:

The "15.000 fps" is apparently the number which you enter in Jaksta's "Fix Time" dialogue. The point is that Jaksta's and Replay Media Catcher 4's help file (help documentation) is not as comprehensive and detailed as, for example, the help files of MetaProducts sophisticated downloaders series (Offline Explorer Pro, Offline Explorer Enterprise, ..). The RMC4 help file doesnt tell you what number you must type in ("Fix Time") if the video/audio playback is out of synch or not smooth.

Now you know.




In Replay Media Catcher (v4.2.1) "Recording Mode", i get:
170 MB (178.714.854 Bytes), crc32:8E71C0A2, and the video clearly needs fixing (because MediaInfo and FLVExtract report strange framerates and or durations). Jaksta's Fix FLV analyzes the raw FLV as "videoframerate = 15", which sounds correct.
after FixTime (with "15"): 170 MB (178.714.859 Bytes), crc32:65AA8EBD, 22mn 7s
then close FixFLV, reopen FixFLV.
after FixDuration: 170 MB (178.714.859 Bytes), crc32:9177E774, 22mn 7s

Clearly, there is "something wrong" in the FLV-header, since the actual duration is 25mn 23s .. as given perfectly by the rtmpdump download result.
