I created a fix but I can't figure out how to mail the patch without the mailing server messing up the format. Setting `is_streamed` to true in the URLContext fixes unix domain socket inputs.

You can create a commit in a local git clone and then create a patch file with something like: `git format-patch -o outgoing/ -M master` This will create a patch file in the directory "outgoing" for each commit since the commit referenced by "master" (you can alternatively specify a hash of the remote commit if you did it on the master branch). The patch can be send to the mailing list with git send-email but if that is not set up and you are worried that your email client is not set up to not mangle it, then sending a regular email and attaching the patch file as an email attachment will usually work as an alternative and it's permitted. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9346#comment:9> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
