When doing version probes for ffmpeg, do the equivalent of calling it as: ffmpeg -version <&- Where <&- is shell syntax for closing stdin before calling the program. This is roughly equivalent to </dev/null without actually opening /dev/null. This prevents ffmpeg -version from hanging when run in the background. Fixes #955. The reason is that ffmpeg tries to manipulate stdin to set up terminal characteristic, and that causes the kernel to suspend the parent process (youtube-dl). Note that closing stdin is achieved by calling subprocess.Popen() with stdin set to subprocess.PIPE and without passing any input to Popen.communicate(). This is somewhat subtle. |
