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. Winxvideo AI 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. Currently, it supports using Intel QSV and NVIDIA CUDA/NVENC hardware acceleration to encode and decode H.264 and HEVC video at 47X real-time faster speed without degrading quality. NVIDIA GeForce RTX 30 Series have special hardware decoding units for AV1 video[1]. Winxvideo AI will add AV1 decode support in the near future. Stay tuned. Besides changing file format, this tool allows you to do some video editing tasks like cutting and merging, and free download AV1 videos from video-hosting sites.
