rtsp: Invalid data found when processing input

[sivaprasanna]

I'm trying to access an RTSP livestream using ffplay. I'm using the following command

ffplay "rtsp://qa.vibrnet.com:80/img/video.sav?MAC=00C0021F1116&channel=2&GUID=betaUser"

But I get an error saying "Invalid data found when processing the input". I tried debugging and this is what I got.

Is the issue only reproducible with ffplay or also with ffmpeg -i input -qscale 2 out.avi?

$ host qa.vibrnet.com
Host qa.vibrnet.com not found: 3(NXDOMAIN)

How can I reproduce the issue?
Which application plays the stream?

[sivaprasanna]

This issue is also with ffmpeg. I tried to save the livestream to a local file. I got the same error. I tried using -loglevel debug, but still the same issue. This is the console output that I got when I tried with debug mode.

D:\..>ffmpeg -loglevel debug -i "rtsp://qa.vibrnet.com:80/img/video.sav?MAC=00C0021F1116&channel=2&GUID=betaUser" c:/video.mp4

And host was not found because you can't access the link. The stream is available internally(within our local network) for testing purposes.

So how can I reproduce the issue?

[sivaprasanna]

I'm sorry I don't know. :/ Maybe you can help me troubleshoot this issue? So that I'll try that and report back?

[Carl Eugen Hoyos]

Where in the code does the command fail currently?

[sivaprasanna]

Since I've just began to work on this, I haven't written any code so far. I'm just playing around ffplay and ffmpeg. My first command was to play the livestream. I used

 ffplay "rtsp://qa.vibrnet.com:80/img/video.sav?MAC=00C0021F1116&channel=2&GUID=betaUser"

It failed then and there. Later just to check whether the issue persists with ffmpeg, I used the following

ffmpeg -i "rtsp://qa.vibrnet.com:80/img/video.sav?MAC=00C0021F1116&channel=2&GUID=betaUser" -f mp4 c:/video.mp4

Again it failed. First, I want to get this simple command working so that I can start writing code to encode the stream with .h264.

Edit: Just to check, can you please try executing this $ host videoqa.alarmnet.com. This one is for another product of us. It also uses a livestream with similar architecture and tech behind it. If that works, I can ask my colleagues to get that rtsp url and give it to you.

Sorry, but I don't quite understand what you're saying.

[Carl Eugen Hoyos]

You asked above:

Maybe you can help me troubleshoot this issue?

FFmpeg currently returns "Invalid data found when processing input" for your input which corresponds to a return AVERROR_INVALIDDATA;. Where in the FFmpeg source code is this return triggered?

If you can provide to provide a command line that allows me to reproduce the issue, I will try to find out where it fails.

[sivaprasanna]

FFmpeg source code? I'm sorry I don't know about that. I just downloaded the build from here ​http://ffmpeg.zeranoe.com/builds/ And I'm using Windows build, if that is of any help. Thank you!

[sivaprasanna]

What do you mean by FFmpeg source code? I just downloaded the windows static build from the link provided in my previous post.

[Carl Eugen Hoyos]

Please feel free to reopen this ticket if you can either debug the issue yourself (you have to be able to compile FFmpeg yourself to do this) or if you can provide a command line that allows a developer to reproduce the issue.

[sivaprasanna]

Okay. I just found this working live stream link. It is not rtsp though, but this stream also doesn't work with ffplay and ffmpeg. It also throws the same "Invalid data found when processing input error". You can try out the following command.

ffplay "http://melon.inlive.co.kr/listen.asx"

I also tried the url with ffmpeg. I get the same "Invalid data"error. Check out the below command.

ffmpeg -i "http://melon.inlive.co.kr/listen.asx" -f mp4 c:/video.mp4
