#10963(undetermined:new): VP9 hardware decoding very slow on Apple Silicon

#10963: VP9 hardware decoding very slow on Apple Silicon -------------------------------------+------------------------------------- Reporter: low-batt | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- What you were trying to accomplish: Play a VP9 encoded video with hardware decoding using [https://iina.io/ IINA] and [https://mpv.io/ mpv] on a MacBook Pro with an Apple Silicon processor. The problem you encountered: Playback stutters because decoding speed drops from 3.28x with software decoding to 0.428x when hardware decoding is enabled. This was reported to IINA in [https://github.com/iina/iina/issues/4554 issue #4554] and [https://github.com/iina/iina/issues/3917 issue #3917]. Reproduced with mpv and reported in [https://github.com/mpv- player/mpv/issues/10587 issue #10587]. Those problems were traced to slow decoding when hardware decoding is enabled. See [https://github.com/mpv- player/mpv/issues/10587#issuecomment-1987262283 this comment]. The VP9 encoded file "Peru 8K HDR 60FPS (FUHD)._original.webm" in the google drive folder [https://drive.google.com/drive/folders/1TSdV36G_npDtjRJze54GEYpdxpBt7nCK 8k] reproduces the slow decoding and playback stuttering when hardware decoding is used. With software decoding playback is fine. For comparision with the HEVC encoded file "new zealand 8k hevc.mkv" in that same directory decoding speed improves from 2.01x with software decoding to 3.56x when hardware decoding is enabled. These times are from a MacBookPro18,2 with the M1 Max chip. Tests run on MacBook Pros with M2 Pro and M3 Pro chips that have an improved Media Engine still exhibited slow decoding and playback stuttering. {{{ low-batt@gag ffmpeg (master $%=)$ time ./ffmpeg -v 9 -loglevel 99 -report -hwaccel videotoolbox -i Peru\ 8K\ HDR\ 60FPS\ $FUHD$._original.webm -benchmark -f null - ffmpeg started on 2024-04-12 at 15:38:17 Report written to "ffmpeg-20240412-153817.log" Log level: 99 ffmpeg version N-114826-g65c1c83ca4 Copyright (c) 2000-2024 the FFmpeg developers built with Apple clang version 15.0.0 (clang-1500.1.0.2.5) configuration: --enable-debug --disable-stripping --enable-pthreads --enable-version3 --enable-ffplay --enable-gnutls --enable-gpl --enable- libbluray --enable-libdav1d --enable-librubberband --enable-libtesseract --enable-libvidstab --enable-libxml2 --enable-libfontconfig --enable- libfreetype --enable-libass --enable-libspeex --enable-videotoolbox --enable-libzmq --enable-libzimg --enable-libjxl --enable-libwebp --disable-libjack --disable-indev=jack --enable-neon libavutil 59. 15.100 / 59. 15.100 libavcodec 61. 5.102 / 61. 5.102 libavformat 61. 3.100 / 61. 3.100 libavdevice 61. 2.100 / 61. 2.100 libavfilter 10. 2.101 / 10. 2.101 libswscale 8. 2.100 / 8. 2.100 libswresample 5. 2.100 / 5. 2.100 libpostproc 58. 2.100 / 58. 2.100 Splitting the commandline.

#11052: ffmpeg 6 and 7 stop ecoding without any error, while ffmpeg 5 works ----------------------------------+--------------------------------------- Reporter: nonamepp | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- Summary of the bug: I used ffmpeg 7 to encode about 100 videos on Windows 11 64 bit. The command is: `for /r %v in (*1080p*.mkv) do ffmpeg -hwaccel auto -i "%v" -loglevel verbose -c:v libx265 -profile:v main10 -pix_fmt yuv420p10le -preset slow -b:v 2048k -map 0:v:0 -map 0:a -map_metadata 0 -c:a aac -ar 48000 -b:a 256k -ac 6 "%~dpnv.ffmpeg.mp4" -n` It works for most videos, and fails for about 5 videos. The symptom is that ffmpeg stops within 1 to 10 seconds, outputs a small video file with 0 byte or hundreds kilobyte. There is no error given at all. I looked into those 5 videos failed to encode: - I tried `-loglevel debug` and `-report`, got no error at all. It simply stops and exits. - I tried to run ffmpeg 7.0.1, 7, 6.1.1, 6.1, 6.0, all got the same result (stops encoding in seconds without any error) - I tried to run them on different Windows 11 64 bit computers (latest build with Intel CPU and AMD CPU), all got the same problem. - I tried to run `ffmpeg -c copy` to copy these 5 videos, and encode the copies, still got the same problem. - I tried to run ffmpeg 5.1.2 and 5.0. It just works (for all 5 videos). So I believe this is a bug and regression in ffmpeg 6 and 7. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11052> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10906: Crash when transcoding h264 with libx265 -------------------------------------+------------------------------------- Reporter: Vasco | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- **Summary of the bug:** Several video files cause ffmpeg to crash (sometimes with "corrupted double-linked list" error, sometimes just a segmentation fault) when transcoding the files to h265. Transcoding to AV1 (with libsvtav1) works. The bug is present in version 6.0.1 from the deb-multimedia repo and in the static binaries for version 6.0.1, 6.1 and the latest nightly (20240301) downloaded from https://johnvansickle.com on Debian Bookworm.
