在IOS上播放Hevc（H265）格式的视频卡顿

[mifeng9999]

视频卡顿，声音和视频不能同步。（我看了下CPU在300%，内存使用在1G以上）（测试机型iphone12）在真机上不行，模拟器是可以的。 视频地址：https://vkceyugu.cdn.bspapp.com/VKCEYUGU-ab498c51-8871-421b-8e23-a43eaa306dff/236d2569-2562-436d-87ca-9dec381a3fa0.m3u8 日志： ***TiercelLog**** Source : SessionManager.swift[235] Thread : number = 1 identifier : com.zl.zlzlzl.flutter_yumei_downloader Info : [manager] retrieveTasks, tasks.count: 0 rootPath:/var/mobile/Containers/Data/Application/BED88762-410F-48B1-82C3-DEFC86A396B4/Library/Caches/m3u8yumeis flutter: setup:true flutter: [inf] 2022-06-08 21:29:19.237493 [fijk] FijkPlayer{id:1} invoke reset #1 flutter: [inf] 2022-06-08 21:29:19.239279 [fijk] FijkPlayer{id:1} invoke reset #1 -> done flutter: [inf] 2022-06-08 21:29:19.239802 [fijk] FijkPlayer{id:1} setOption k:mediacodec-hevc, v:1 flutter: [inf] 2022-06-08 21:29:19.240 [fijk] FijkPlayer{id:1} setOption k:mediacodec, v:1 flutter: [inf] 2022-06-08 21:29:19.240128 [fijk] FijkPlayer{id:1} setOption k:mediacodec-all-videos, v:1 flutter: [inf] 2022-06-08 21:29:19.240602 [fijk] FijkPlayer{id:1} invoke setDataSource https://vkceyugu.cdn.bspapp.com/VKCEYUGU-ab498c51-8871-421b-8e23-a43eaa306dff/236d2569-2562-436d-87ca-9dec381a3fa0.m3u8 flutter: [inf] 2022-06-08 21:29:19.240945 [fijk] FijkPlayer{id:1} state changed to FijkState.initialized <= FijkState.idle flutter: FijkState.initialized flutter: [inf] 2022-06-08 21:29:19.241767 [fijk] FijkPlayer{id:1} invoke prepareAsync ===== versions ===== ijkplayer : f0.7.16 FFmpeg : ff4.0--ijk0.8.8--20211030--926 libavutil : 56.14.100 libavcodec : 58.18.100 libavformat : 58.12.100 libswscale : 5.1.100 libswresample: 3.1.100 ===== options ===== player-opts : overlay-format = fcc-bgra player-opts : start-on-prepared = 0 player-opts : enable-position-notify = 1 player-opts : videotoolbox = 1 player-opts : reconnect = 5 player-opts : mediacodec-hevc = 1 player-opts : mediacodec = 1 player-opts : mediacodec-all-videos = 1 format-opts : ijkapplication = 4376572544 format-opts : ijkiomanager = 4376498288 format-opts : analyzeduration = 1

打错字了 是掉帧 https://rmt-anning-hz-file.vcdn.kmzscc.com/anningrongmei/anningrongmei/2023/05/04/BxTDmA2hBEu40.mp4 是因为编码的问题嘛 视频这块不是太懂
