But, VLC Can't Always Play AV1 Video File
Some users reported that they got an error message saying "Codec not supported: VLC could not decode the format "av01" (AOMedia's AV1 Video)" when they tried playing an AV1 encoded video file. Some said that only audio played, no video.
To fix this, you can convert the AV1 encoded video to a more universally recognized video codec. WinX HD Video Converter Deluxe is fully compatible with AV1 file, and can convert AV1 encoded file to H.264, H.265/HEVC, MP4, MOV, WMV, AVI, FLV, and so on. Supporting Intel QSV and NVIDIA CUDA/NVENC hardware acceleration, the conversion speed can reach 47x real-time faster without degrading quality. Besides changing file format, WinX allows you to do some video editing tasks like cutting and merging, and free download AV1 videos from YouTube and other video-hosting sites.
Free download WinX HD Video Converter onto Windows or Mac computer to decode AV1 video.
