ffprobe doesn't properly follow redirect on remote url

Description

Using ffprobe on remote URL fails when the remote server return 302 redirect to a long URL

  1. ffprobe <remote url>
  2. The remote server returns HTTP 302 Found. The Location header in the response contains a rather long URL
  3. ffprobe tries to follow the redirect, but cuts the URL from the location header and thus requests invalid URL

Do I understand correctly that your issue is not reproducible with ffmpeg?

comment:2 by azhelev, 15 months ago

Hello cehoyos,

the issue is reproducible with ffmpeg too. I have reproduced the case with a file on a web server that i control.

$ ffmpeg -v 9 -loglevel 99 -i "http://77.238.90.90/play/vimeo-prod-skyfire-std-us/01/697/15/378487171/Práctica+mirar+la+imagen+instantánea+en+la+distancia+fácil+y+difícil..mp4" -f image2 -vframes 1 image%03d.jpg

ffplay is also affected

Hello,

it looks like this bug is specific to Linux. This works fine on Mac.

comment:4 by Chris Miceli, 14 months ago

Resolution: invalid
Status: newclosed

I have a fresh build of ffmpeg/ffprobe and this works on my Arch linux laptop.

It appears to actually be something with the server itself reporting that it doesn't have the asset. I tested with the vimeo link in curl (it is a dead link now, but that is to be expected after weeks) and with the hardcoded ip address link with ffmpeg and I cannot reproduce your error.

I did notice that in the bottom of the first link, it was a 403 indicating that it's not an issue with getting to the material but a matter of authentication not succeeding. With the second potential truncation, that appears to be in the logging as the final line has the full output.

I'm going to close this one as it appears to be in the source material and not FFMPEG, but please feel free to reopen if I'm wrong and you have some more information which I might be missing.
