Hi, By default, hls will autodetect the input format of the downloaded segments. This new option allows to force some specific format, which is useful for hardware decoders that accept only TS (by supplying hls_force_input_format="mpegtsraw" option to avformat_open_input).
The situation has been mentioned in the FFmpeg-users mailing list, so this patch might be useful: https://lists.ffmpeg.org/pipermail/ffmpeg-user/2013-October/018306.html This option should probably be documented somewhere, but I failed to find an appropriate place. Please comment, so I can update the patch.
