Could not open stream #20

Closed mrshankly closed 11 years ago

mrshankly commented 11 years ago

I'm getting this error every time I try to open a stream: error: Could not open stream - Error while executing subprocess

I'm using Ubuntu 12.04 and have the last git of rtmpdump installed. It happens for both twitch.tv and own3d.tv streams.

You have to compile rtmpdump from source. On Ubuntu, first install the dependencies. You can get all or most of all of them at once with $ sudo apt-get -y build-dep rtmpdump

Then in a terminal in your home directory, issue:

$ git clone git://git.ffmpeg.org/rtmpdump && cd rtmpdump/ && make && sudo make install

If it complains that it's missing something, track it down using $ apt-cache search package-name

or packages.ubuntu.com

Also make sure you have vlc installed, because that's the default player it looks for and will fail if it does not find it. You can also change it to mplayer in a config file as it talks about in the README.

Tried to reinstall rtmpdump, everything went fine, but I'm still getting the same error:

Yes, vlc is installed:

Everything worked fine before, but my version of rtmpdump didn't support the jtv token, and since the update I'm getting that error. The older version of rtmpdump was installed from the repositories with just sudo apt-get install rtmpdump. I also removed it before installing the new version.

Is livestreamer up to date? It got some fixes a few hours ago.

$ git clone git://github.com/niallm90/livestreamer.git && cd livestreamer && sudo python setup.py install

mrshankly commented 11 years ago

Yeah, that's the first thing I did when I got the error.

codygarver commented 11 years ago

That's really weird, I only recently got it working for myself. Sorry I couldn't help, hopefully the author can soon.

  1. Check what happens when you run rtmpdump without any arguments. Any linker errors or segfault?
  2. Run livestreamer with the --errorlog option and paste the output from the file specified here.
  3. Run livestreamer with the --cmdline option and paste the output.

When I run rtmpdump without any arguments I get this:

Hmm, the command line you posted works fine here.

It might be a long shot, but your rtmpdump could be linking with the Ubuntu version of librtmp. You can see if this is the case when you type "ldd /usr/local/bin/rtmpdump". If it lists the librtmp in /usr/lib instead of /usr/local/lib then that's probably the issue.

mrshankly commented 11 years ago

Looks like you're right:

$ ldd /usr/local/bin/rtmpdump
linux-gate.so.1 =>  (0xb77c6000)
librtmp.so.0 => /usr/lib/i386-linux-gnu/librtmp.so.0 (0xb7795000)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb75f0000)
libgnutls.so.26 => /usr/lib/i386-linux-gnu/libgnutls.so.26 (0xb752b000)
libgcrypt.so.11 => /lib/i386-linux-gnu/libgcrypt.so.11 (0xb74a6000)

libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xb7446000)

How can I fix it tho?

chrippa commented 11 years ago

Well, you can just remove the librtmp package, but if that causes other programs that may depend on the library to be removed aswell then maybe you could just move the librtmp files in /usr/lib out of the way see if it helps. You might need to recompile rtmpdump though.

mrshankly commented 11 years ago

When I moved the librtmp files in /usr/lib out of the way, rtmpdump wouldn't run, even after recompiling. After that I copied the librtmp files from /usr/local/lib to /usr/lib and it worked.

Everything is running fine now. Thanks a lot for the help.

soppen commented 11 years ago

I had the same issue. When I recompiled rtmpdump I noticed in the log that "cp librtmp.so.0 /usr/local/lib" but in "ldd /usr/local/bin/rtmpdump" it says "librtmp.so.0 => /usr/lib/librtmp.so.0" so I: sudo cp /usr/local/lib/librtmp.so.0 /usr/lib/

Working nicely now :) Running Debian btw, and I had this error: ERROR: Closing connection: NetStream.Play.Failed
