使用 Nvidia GPU 加速的 Ffmpeg 帧提取抛出“输出文件 #0 不包含任何流”

【中文标题】使用 Nvidia GPU 加速的 Ffmpeg 帧提取抛出“输出文件 #0 不包含任何流”

【英文标题】：Ffmpeg frame extraction with Nvidia GPU acceleration throws "Output file #0 does not contain any stream"

【问题描述】：

我正在尝试将 nvidia gpu 加速解码器 api 与 ffmpeg 一起使用，以将视频文件 (.MTS) 中的所有帧提取到一个文件夹中，但它看起来由于某种原因失败了；我找不到答案或类似问题。

使用的命令：

ffmpeg -vsync 0 -hwaccel cuvid -c:v mpeg2_cuvid -i raw_video.MTS -q:v 2 -f image2 output_folder/image_%05d.jpg

我很确定-hwaccel cuvid -c:v mpeg2_cuvid 是正确的，因为文件属性中的文件类型似乎是 MPEG-2，但其他 cuvid 解码器也会出现类似问题：

我也尝试在没有-c:v 标志的情况下运行，但随后出现 cuda 错误并在 cpu 上运行：

[h264 @ 0x55949e6d7e00] decoder->cvdl->cuvidCreateDecoder(&decoder->decoder, params) failed -> CUDA_ERROR_INVALID_VALUE: invalid argument [h264 @ 0x55949e6d7e00] Failed setup for format cuda: hwaccel initialisation returned error.

任何帮助将不胜感激。

分享ffmpeg -i raw_video.MTS的日志

@Gyan 添加了输出！

视频流是h264，不是mpeg2。使用-c:v h264_cuvid

这实际上是我尝试的第一个，它似乎导致另一个错误：Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scaler_0' Error reinitializing filters! Failed to inject frame into filter network: Function not implemented Error while processing the decoded data for stream #0:0 Conversion failed!

在输入后添加-vf hwdownload,format=yuv420p

【参考方案1】：

视频编解码器实际上是h264。 MPEG2-TS 是一种容器/封装格式，不必只包含 MPEG-2 视频流。

使用硬件解码器（如cuvid）解码视频时，解码的帧位于硬件设备内存中特定于硬件的数据布局中。在将它们传输到系统内存之前，需要将它们转换为可接受的布局。

添加过滤器 hwdownload 以将帧复制到系统内存，然后立即添加格式过滤器以指定下载的 hwdownload 格式。 nv12 是 yuv420p 的变体，在 ffmpeg 中可以进行 hW->SW 转换。

ffmpeg -hwaccel cuvid -c:v h264_cuvid -i raw_video.MTS -vf hwdownload,format=nv12 -vsync 0 -q:v 2 -f image2 output_folder/image_%05d.jpg
