# Limitations of FFmpeg VVC encoder # Limitations of FFmpeg VVC encoder
Before encode to VVC video codec, see the limitations below. Before encoding VVC video codec, see limitations below.
libvvenc (FFmpeg vvc version) works for: FFmpeg-VVC (for libvvenc feature) works for:
- Pixel format ⚠️ (only pixel format 10 bit is default, but you can still encode 8 bit by using vvenc params `-vvenc-params InternalBitDepth=8`) | Features | Notes |
- Video size (auto detects, but it doesn't detect for SAR and DAR anamorphic is glitch and corrupts the video) ⚠️ (Better way to use vvencapp without FFmpeg) --- | --- |
- Frame rate ✅ (auto detects) Pixel format | ⚠️ (only pixel format 10 bit is default, but you can still encode 8 bit by using vvenc params `-vvenc-params InternalBitDepth=8`)
- MP4/TS Mux ✅ (only works for stable if it's encoded VVC with MP4 or TS on FFmpeg and mp4box for muxing still works) Video size | (auto detects, but it doesn't detect for SAR and DAR anamorphic is glitch and corrupts the video) ⚠️ (Better way to use vvencapp without FFmpeg)
- Mux MP4/TS container from raw bitstream on FFmpeg ⚠️ (the first frame freezes may just print error messages for libvvdec when muxed and seeking in FFmpeg, use mp4box for recommendation) Frame rate | ✅ (auto detects)
- Matroska mux ⚠️ (Only matroska mux has an experimental, causing problem of the video sync delay with audio and others for FFmpeg libvvdec. It is unofficial support) MP4/TS Mux | ✅ (only works for stable if it's encoded VVC with MP4 or TS on FFmpeg and mp4box for muxing still works)
- Demux ✅ Mux MP4/TS container from raw bitstream on FFmpeg | ⚠️ (the first frame freezes may just print error messages for libvvdec when muxed and seeking in FFmpeg, use mp4box for recommendation)
- Audio with encode VVC ✅ Matroska Mux | ⚠️ (Only matroska mux has an experimental, causing problem of the video sync delay with audio and others for FFmpeg libvvdec. It is unofficial support)
- Broadcasting ✅ (MPEG-TS) Demux | ✅
- Streaming ✅ (MPEG-DASH) Audio with encode VVC | ✅
- Bitrates ✅ (average (`-b:v`) and maximum bitrate (`-maxrate`) are only supported) Broadcasting | ✅ (MPEG-TS)
- Passes ⚠️ (you may need get passes using vvenc params on FFmpeg VVCEasy or use vvencapp, also it is only available to use bitrate for two passes, QP supports only one pass) Streaming | ✅ (MPEG-DASH)
- Presets ✅ Bitrates | ✅ (average (`-b:v`) and maximum bitrate (`-maxrate`) are only supported)
