ffmpeg+CRTMPServer+ffplay: File not found. fullPath:

[windj007]

Hello!

First of all I'd like to thank you for good job! The server works "out
of the box" in case of flv-files' streaming.

I have the dataflow "ffmpeg -> crtmpserver -> ffplay" that is
configured as follows:

1) Launch crtmpserver using original crtmpserver.lua configuration
file (which was in tarball crtmpserver-717.tar.gz).

2) Launch ffmpeg:
ffmpeg -re -an -i <input file> -f flv -an -metadata
streamName="test" tcp://localhost:6666
As a result, ffmpeg starts to encode and to send video.
crtmpserver' output by the moment is in Listing 1 (in the end of
this letter).
Everything seems to be ok by the moment.

3) ffplay's command: ffplay -an rtmp://127.0.0.1/flvplayback/test

ffplay exits with the following error right away:
HandShake: client signature does not match!
rtmp server sent error
WriteN, RTMP send error 32 (42 bytes)
RTMP_ReadPacket, failed to read RTMP packet header
rtmp://127.0.0.1/flvplayback/test: Operation not permitted

crtmpserver outputs the following errors:

What's the matter?
CRTMPServer seems to receive video from ffmpeg correctly (the stream
named 'test' was registered to application 'flvplayback')...

Thank you!

[C++ RTMP Server]

Hi,

After you start the playback with ffplay, look on the server console. Copy paste the line similar to this one:

"Play request for stream name `rtsp_test`. Start: -2; length: -1"

Cheers,
Andrei

Hi,

Here it is: "Play request for stream name `test`. Start: 0; length:
-1"

Can you please provide proper config related to ability of pushing
stream from ffmpeg to crtmpd?

[windj007]

Hi,

I use default crtmpserver.lua without any modifications (sources
tarball: http://www.rtmpd.com/assets/sources/crtmpserver-717.tar.gz).

Best regards,
windj007

Obviously the problem is that crtmpserver does TryLinkToFileStream
instead of TryLinkToLiveStream.
It happens so because of M_INVOKE_PARAM(request, 2) returning 0.
I haven't found how to set startTime by the moment.

[Eugen-Andrei Gavriloaie]

That is absolutely correct. Please *carefully* read about
NetStream.play method on Adobe docs. Crtmpserver is doing the correct
thing

[windj007]

The problem is solved!

In order to watch live RTMP stream through ffplay one should use a
command like following:
ffplay "rtmp://your-server.com/application/stream live=1"

It's worth noticing that ffmpeg uses librtmp having a number of
compatibility issues.

In the end I configured JWPlayer as described in tutorials and all
started working.

Correct me if I'm wrong.

Thank you for your responses!
