obs-ffmpeg/ffmpeg-mux: Use separate printable URL target (Jim) printable_file allows the ability to keep a separate string for logging which will not contain things like stream keys when used with outputs such as HLS.

obs-ffmpeg: Allow specifying mux settings directly (Jim) Allows the ability to specify mux settings directly on the output's structure itself rather than just via settings. This is useful for network-based muxer outputs (such as HLS).

obs-ffmpeg: Allow using stream keys with muxer (Jim) Allows the ability to use stream keys with ffmpeg-mux -- this will enable the ability to use it with certain services (such as YouTube) which allow different protocols (such as HLS)

obs-ffmpeg: Split ffmpeg_muxer output file by size or time This commit adds 3 new properties to split output file in the output `ffmpeg_muxer`. - `max_time_sec` specifies the limit in seconds. - `max_size_mb` specifies the limit in megabytes. - `allow_overwrite` specifies to test an existing file. If both `max_time_sec` and `max_size_mb` are not positive, the split file feature won't be enabled. Another output ffmpeg_mpegts_muxer shares the code but is not affected since the output is used only for streaming.

obs-ffmpeg: Add HLS output Add and register an obs_output_info struct called ffmpeg_hls_muxer. It uses ffmpeg's HLS muxer to stream output. Add threading and buffer to reduce skipped frames. Also add frame drop logic when there are too many packets in the buffer for congestion control.

obs-ffmpeg, UI: Reset timestamps at splitting file This commit adds a setting to reset timestamps when splitting files. Some NLEs cannot handle video files whose starting timestamp is not zero. Default is enabed.
