ffmpeg で nvidia GPU アクセラレーション デコーダー API を使用して、ビデオ ファイル ( .MTS
) からすべてのフレームをフォルダーに抽出しようとしていますが、何らかの理由で失敗しているようです。答えや同様の問題が見つかりませんでした。
使用したコマンド:
ffmpeg -vsync 0 -hwaccel cuvid -c:v mpeg2_cuvid -i raw_video.MTS -q:v 2 -f image2 output_folder/image_%05d.jpg

ファイルのプロパティでファイルの種類が MPEG-2 のように見えるため、正しいと確信-hwaccel cuvid -c:v mpeg2_cuvid
していますが、他の cuvid デコーダーでも同様の問題が発生します。
フラグなしで実行しようとしまし-c:v
たが、cuda エラーが発生し、CPU で実行されます。
[h264 @ 0x55949e6d7e00] decoder->cvdl->cuvidCreateDecoder(&decoder->decoder, params) failed -> CUDA_ERROR_INVALID_VALUE: invalid argument

どんな助けでも大歓迎です。
