I have a configuration
<channels>
<channel>
<video-mode>720p5000</video-mode>
<consumers>
<screen />
<ffmpeg>
<path>/opt/casparcg/output/test.m3u8</path>
<args>-codec:v h264_nvenc -profile:v high -preset:v p1 -codec:a aac -b:a 192k -filter:a pan=stereo|c0=c0|c1=c1 -filter:v format=yuv420p,fps=30 -hls_time 1 -hls_list_size 3 -hls_flags delete_segments+append_list</args>
