#11572: HEVC interlaced reported as progressive; wrong DAR -------------------------------------+------------------------------------- Reporter: Peter | Type: defect Krefting | Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: hevc | Blocked By: interlaced | Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: A HEVC broadcast video stream encoded by the Makito encoder configured to use HEVC 1920×1080i video is identified as 1920×540p. How to reproduce: The following captures were provided to us by the broadcaster, and I have been given permission to share them for the purpose of this bug report. They were created by the Makito encoder software: * [https://www.dropbox.com/scl/fi/77pmthkf3uv3zf3a4yjfk/hevc- interlace-1.ts?rlkey=ray5xnepc2lwuzzomccujiaqf&dl=1 Sample 1] * [https://www.dropbox.com/scl/fi/oqag1b7f8t8lqettjolst/hevc- interlace-2.ts?rlkey=pp1wah7ep32pbx355tcbszb7v&dl=1 Sample 2] Running ffprobe on the samples detects them as 1920×540p with a 32:9 DAR, and playing them with ffplay do display them in 32:9. {{{ $ ffprobe /tmp/hevc-interlace-2.ts ffprobe version N-119410-g33d0d1c672 Copyright (c) 2007-2025 the FFmpeg developers built with gcc 12 (Debian 12.2.0-14) configuration: libavutil 60. 2.100 / 60. 2.100 libavcodec 62. 2.100 / 62. 2.100 libavformat 62. 0.102 / 62. 0.102 libavdevice 62. 0.100 / 62. 0.100 libavfilter 11. 0.100 / 11. 0.100 libswscale 9. 0.100 / 9. 0.100 libswresample 6. 0.100 / 6. 0.100 [hevc @ 0x55a556e149c0] PPS id out of range: 0 [hevc @ 0x55a556e149c0] Skipping invalid undecodable NALU: 39 [hevc @ 0x55a556e149c0] PPS id out of range: 0 [hevc @ 0x55a556e149c0] Skipping invalid undecodable NALU: 0 [hevc @ 0x55a556e149c0] PPS id out of range: 0 [hevc @ 0x55a556e149c0] Skipping invalid undecodable NALU: 39 [hevc @ 0x55a556e149c0] PPS id out of range: 0 [hevc @ 0x55a556e149c0] Skipping invalid undecodable NALU: 1 [hevc @ 0x55a556e149c0] PPS id out of range: 0 (...messages repeats...)
