As a result, for proxies honoring Accept-Encoding, the following bug occurs: $ youtube-dl -vs --cn-verification-proxy https://secure.uku.im:993 "test:letv" [debug] System config: [] [debug] User config: [] [debug] Command-line args: ['-vs', '--cn-verification-proxy', 'https://secure.uku.im:993', 'test:letv'] [debug] Encodings: locale UTF-8, fs utf-8, out UTF-8, pref UTF-8 [debug] youtube-dl version 2015.12.23 [debug] Git HEAD: 97f18fa [debug] Python version 3.5.1 - Linux-4.3.3-1-ARCH-x86_64-with-arch-Arch-Linux [debug] exe versions: ffmpeg 2.8.4, ffprobe 2.8.4, rtmpdump 2.4 [debug] Proxy map: {} [TestURL] Test URL: http://www.letv.com/ptv/vplay/22005890.html [Letv] 22005890: Downloading webpage [Letv] 22005890: Downloading playJson data ERROR: Unable to download JSON metadata: Not a gzipped file (b'{"') (caused by OSError('Not a gzipped file (b\'{"\')',)); please report this issue on https://yt-dl.org/bug .
