	PR: https://github.com/ytdl-org/youtube-dl/pull/29688 Closes: #617, https://github.com/ytdl-org/youtube-dl/issues/29665 * Livestreams are untested * If using ffmpeg as downloader, v4.3+ is needed since `-http_seekable` option is necessary * Instead of making a seperate key for each arg that needs to be passed to ffmpeg, I made `_ffmpeg_args` * This deprecates `_seekable`, but the option is kept for compatibility Authored by: nchilada, pukkandan
