v0.2.3

Release Notes

Added

• Playout schema 0.0.7: canvas graphics layers accept an optional layout
  • This can be used to composite a canvas smaller than the final output size
• Probe for HDR10 metadata using first frame of local and HTTP sources, when probe_hint omits has_hdr10_metadata for smpte2084 video
  • This allows hardware tonemapping (QSV) for e.g. media server content that doesn't reliably report HDR10 metadata

Changed

• Remove VideoToolbox h264 encoder workaround that stripped A53 closed captions
  • This is no longer needed with ErsatzTV-ffmpeg 8.1.2-5

Fixed

• Fix channels falling behind schedule when the playout JSON is updated or replaced
• Fix image subtitles (e.g. PGS) missing or misplaced with hardware acceleration when the subtitle size differs from the video size (e.g. cropped video)
• Fix VAAPI stream failing when software pad is used before tonemap_opencl
• Fix QSV stream failing when no Intel device is found; the channel now uses a software pipeline
• Fix QSV green padding on Windows with certain HDR content
• Fix slow transcoding of high-resolution video with PGS subtitles until the first subtitle appears
• Fix RKMPP stream failing with loudness normalization
• Fix VAAPI blocky, smeared h264 video on older AMD GPUs

Compatibility

• Channel config: reads versions 0.1.0 to 0.1.2
• Lineup config: reads versions 0.0.0 to 0.0.1
• Playout: reads versions 0.0.0 to 0.0.7
• ErsatzTV-ffmpeg: 8.1.2-5, bundled in the docker images and recommended for the native binaries
