FFMPEG HTTP protocol not generation authorization line

[Roman Gaufman]

I have an acti camera, I can send these headers to it to receive an MJPEG stream:

GET /cgi-bin/cmd/system?GET_STREAM HTTP/1.1
User-Agent: Mozilla/5.0 Lavf/55.8.102
Accept: */*
Host: 192.168.1.40
Connection: Close
Range: bytes=0-
Authorization: Basic YWRtaW46MTIzNDU2

However when I run:

ffmpeg -i "​http://admin:123456@192.168.1.40/cgi-bin/cmd/system?GET_STREAM"

And capture what it sends with tcpdump, I see it sends these headers:

GET /cgi-bin/cmd/system?GET_STREAM HTTP/1.1
User-Agent: Mozilla/5.0 Lavf/55.8.102
Accept: */*
Range: bytes=0-
Connection: close
Host: 192.168.1.40

Notice there are identical except FFMPEG doesn't generate the Authorization line. Isn't it meant to?

I'm using ffmpeg version N-53816-g55121f3 compiled Jun 4 2013 on Ubuntu 13.04.

Replying to hackeron:

ffmpeg -i "http://admin:123456@192.168.1.40/cgi-bin/cmd/system?GET_STREAM"

Do I understand correctly that you do not receive anything with this command?
Please provide the complete, uncut console output to make this a valid ticket.

[Roman Gaufman]

Sure, here you go:

Consider adding the exact type of camera that needs this http header line.

[Roman Gaufman]

The specific cameras I'm using are ACTi E32 and ACTi D71 but I'm guessing any camera that requires HTTP basic authorization will not work with FFMPEG at the moment.

[Carl Eugen Hoyos]

HTTP basic authorization is supported by FFmpeg, if I understand the code correctly, 401 should make FFmpeg retry with authorization.

Do you have a possibility to make a camera visible to the internet?

[Roman Gaufman]

I'm made the camera available over internet. To reproduce, please run: ffmpeg -i "​http://admin:123456@proxy81.zanview.com/cgi-bin/cmd/system?GET_STREAM"

Then run: curl "​http://admin:123456@proxy81.zanview.com/cgi-bin/cmd/system?GET_STREAM" >/dev/null to see it working :)

[Carl Eugen Hoyos]

I unfortunately get a different error here:

You could try with an older version or start debugging yourself: There is code in libavformat/http.c and libavformat/httpauth.c that should create the basic "Authorization:" line for the http header.

Sorry my bad! - closed the console by accident so the ssh tunnel died. I've put it in a screen session now so should be as expected now.
