LTR can be used in two modes: "LTR Trust" mode and "LTR Per Picture" mode. LTR Trust mode: In this mode, ltrNumFrames pictures after IDR are automatically marked as LTR. This mode is enabled by setting ltrTrustMode = 1. Use of LTR Trust mode is strongly discouraged as this mode may be deprecated in future. LTR Per Picture mode: In this mode, client can control whether the current picture should be marked as LTR. Enable this mode by setting ltrTrustMode = 0 and ltrMarkFrame = 1 for the picture to be marked as LTR. This is the preferred mode for using LTR. Note that LTRs are not supported if encoding session is configured with B-frames
