You may need to review what the error message is when the job fails. Does it indicate an issue with source file? Please verify the name of the source file for the AWS MediaConvert job contains no additional characters, such as a space.
Do you know what is the wrapper type for the H265 encoded file? Is it an MP4 or some other format? You may try changing the extension from .265 to .mp4.
Also, the template System-Ott_Hls_Ts_Hevc_Aac creates HLS with HEVC (H.264) encoded video. Is this what is needed? Perhaps the System-Ott_Hls_Ts_Avc_Aac could be used to create H.264 HLS renditions.
