Rtmp Flv Audio And Video Problem

[roaringlion]

hi,

i was doing great using RTMP, many videos downloaded good, but all of a sudden any other new videos that i download, are now downloading corrupted.

the flv. files are having problems playing their audio and video:

//a quote from vlc

No suitable decoder module:
VLC does not support the audio or video format "undf". Unfortunately there is no way for you to fix this.

i tried redownloading again those files that had downloaded good, and now they are downloading corrupted as well.

really don't know what went wrong

a screeny from the rtmpsrv

i did download this perfectly, and it worked

i reached till vid 7, and they started becoming corrupted

tried again this video i sent, which downloaded good, and now it is corrupted

something i noticed is that the random names were really long in the beginning, and now they're short;

like 724-1-h

moreover here's a screeny of the rtmpsrv

Use rtmp-host.sh

$ rtmp-host.sh
Press enter after video starts

127.0.0.1 cp101677.edgefcs.net
Press enter to start RtmpSrv, then restart video.

I have the exact same problem as you. I downloaded well until lesson 10 and at the 11th lesson they all started to get corrupted FLV. Even if I tried previous lessons, there a now corrupted. I am really interrested in this issue too.

i think as well it has something to do with DT, did you find anything?

am now clueless, there must be a way, but cannot find it,

i noticed that when they worked, the file names of the flvs where really long, but when there were corrupted the file names were short

---

what i think is that all these people can download the free tutorials, i can download them as well and they work when am logged out, but once logged in..no longer work, it must be from dt

Paid videos from DigitalTutors are protected by FlashAccess DRM.

I did some tries with rtmp-host.sh but it doesn't work, once rtmpsrv is waiting, there is no way to start the video anymore, the flash player seem crashed.

I am thinking on two possible cause.

- DT as started a new protection system yesterday while we were ripping the video, and now it doesn't work anymore (strange coincidence though).

- DT set all paid account on a specific stream server with less protection (to reduce the server load). And when they detect suspicious usage, the account is changed to a more secure stream server with a kind of rtmpsvr counter protection.

May be a bit stupid, but it really look like it's a DT specific problem. Personnaly I going to stop trying cause I don't want my 45$ account to get suspended

I have found the security of DT, but I don't know how to counter it, maybe someone here could help with that.

When you start a video on DT, it first start a fake video of the correct length and then 2 sec after, the player restart and begin the real video.

The problem is that all the stream recorder tool start on the first fake video, and so download a fake and unreadable FLV.

I don't know how I could do to detect the second video because when rtmpsvr catch the first stream, it stop the player so the second one never start.

I need a way to tell rtmpsvr to ignore the first video and detect the second one ?
