unusual streaming (RTMPT, port:80) www.tvs.pl

[placebo]

Thanks for the tip. I've done now "Fix FLV" (context menu command) and then also "Fix Duration" (in the Fix FLV-dialogue). File size is 170 MB (178.714.825 Bytes), and crc32: B22D28E8

No change. On my system, the 170MB-version files dont play smooth, as mentioned before. The 350MB-version files (rtmpdump:1935, HiDownload ) do play smoothly with *all* players on my system. I conclude from this that the "correct file size" lies in the range 350-370MB, and that the 170MB file is a corrupt file (or file size).

I would strongly suggest that you share your file which was downloaded by Replay Media Catcher 4 (4.1.9), then i can compare the binary contents with BeyondCompare or Araxis.

I will, too, upload my file (later).

I tried to use HiDownload and it has downloaded 783 MBs already... and it is not going to stop



Do you think the bigger the size the better?

So HiDownload 7.99 downloaded a 1.16 GB file. It has the same video resolution of 680x382, the same 15fps, the same AAC audio. I can't play it in both Applian FLV Player and KMPlayer without fixing . And I don't see any increase in quality.

The only difference I can see is that the video downloaded by Replay Media Catcher is 22 min 07 sec long, while the video downloaded by HiDownload is 25 min 23 sec long.

i've deinstalled HiDownload already *ggg*
i purchased a personal license (to support them) but their product isnt the best

Thanks SR for having uploaded the FLV-file (your PM, 170MB version). I am .. your file is
170 MB (178.714.825 Bytes), crc32: CA531ECE
and it does play smoothly in VLC player (and other players)!!
I would say that there are some intermittent sound defects (punctual audio defects) .. which could be neglected at this stadium of trial&error.

I will send you a series of screenshots of my settings, see PM. I need to reproduce your download result.

i am shocked.

This RTMP stream is live, so it shouldn't matter whether you use the RTMP Super Download or not.

May be the problem is with the Fix FLV tool of Replay Media Catcher 4.1.9. I saw the following in the applian user forums

When i didn't do step b. 'close' there were times the slider didnt appear !

Try this. If you can confirm the Arno's assumption, I will notify the developer.

How to use 'Fix FLV'-tool in Replay Media Catcher

SR, finally i got it with the above instructions! Today i captured the video again:
In RMC v4.1.9 i turned off "automatic fixing" and went into "Downloading"-mode (as opposed to "Recording"-mode):
170 MB (178.714.820 Bytes), D9418FAF

Then after "Fix Duration":
170 MB (178.714.825 Bytes), B22D28E8

Then after "Fix Time":
170 MB (178.714.825 Bytes), CA531ECE

..which is exactly the same crc32 as your uploaded file!
This also means that the software is able to download reproducible results, congratulations!

use CooJah.

rtmpt ://... (need to remove the "t" at the end of links,in the properties of loading)> rtmp ://...

[placebo]

,

thank you chap. i have removed the "t" and the download finishes after a while. the file size is big (similar to rtmpdump and HiDownload ). 2 testruns give 2 different file sizes. both videos play seemingly fine. ( and what about Coojah's "RTMP Record"-mode here? CooJah's "RTMP Recording"-mode doesn't seem to save anything? )

result (downloaded not as "live video"):
testrun1: 366 MB (384.750.520 Bytes), crc32: 289F67F2
testrun2: 386 MB (405.092.439 Bytes), crc32: 783C388F

Verdict:
Apparently the RTMPT stream is still a challenge to all software coders. No software produced 100% perfect results. And whatever you download, you can be sure that the file is NO WAY THE SERVER FILE. If you need perfect video server files, then delete your downloaded streams!! Otherwise, here is the ranking (as of early May, 2011):

1st prize: n/a
shared 2nd prize: Replay Media Catcher. file size is reproducibly 170MB, and video can be played back smoothly (with minimal audible defects in VLC media player). downloaded *.FLV-file required heavy fixing ("Fix duration" + "Fix Time")!
shared 2nd prize: rtmpdump (command line version by nullacht). file size is reproducibly 170MB, and video can be played back smoothly (with ?? audible defects in VLC media player). no fixing of the *.FLV was needed.
shared 3rd prize: Blader. 2 test drives result in 2 file sizes (~360MB). video plays smoothly in all players. no sign of videographic or audible corruption.
shared 3rd prize: HiDownload . here too, 2 test drives, 2 file sizes (350-370MB). video plays smoothly in all players. no sign of videographic or audible corruption.
pending: GetFLV. (GFLV Team promised to include RTMPT support in some future versions/updates of their product. fingers crossed!)

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.

shared 3rd prize: Blader. 2 test drives result in 2 file sizes (~360MB). video plays smoothly in all players. no sign of videographic or audible corruption.

You forgot to specify the "Download live video" = file size is ~ 1 / 2.
"Download live video"


"Download live video" it is not.
