FFmpeg 使用 qsv 加速失败

[wapollo9]

ffmpeg 命令如下

ffmpeg -y -c:v h264_qsv -i input.mp4 -c:v hevc_qsv -low_power 1 output.mp4

输出的错误信息如下

[hevc_qsv @ 0x562ef30a0480] Selected ratecontrol mode is unsupported
[hevc_qsv @ 0x562ef30a0480] some encoding parameters are not supported by the QSV runtime. Please double check the input parameters.

谢谢各位了

[datou]

你这 vainfo 都是解码规格支持吧？

qsv 编码应该只支持 avc ，hevc 和 vp9/av1

[RangerWolf]

我在我的 i5-5800H 上面成功执行下面转码率的命令
.\ffmpeg.exe -hwaccel qsv -c:v h264_qsv -i input.mp4 -c:v h264_qsv -b:v 5M output-qsv.mp4

你可以试试看。不知道是不是所有的 Intel CPU 都支持 QSV

[ysc3839]

QSV 和 VAAPI 不是同一个东西，建议先确认一下有没有装 Intel MSDK

[acreti]

ffmpeg -h encoder=hevc_qsv
-low_power 是实验选项，有限制

[L4Linux]

要装 intel media sdk

[Huelse]

先看下有没有支持

`ffmpeg -hide_banner -encoders | grep qsv`

[wapollo9]

首先谢谢各位的回复

@datou
@Huelse
@acreti
ffmpeg -hide_banner -encoders | grep qsv 结果如下
V..... h264_qsv H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (Intel Quick Sync Video acceleration) (codec h264)
V..... hevc_qsv HEVC (Intel Quick Sync Video acceleration) (codec hevc)
V..... mjpeg_qsv MJPEG (Intel Quick Sync Video acceleration) (codec mjpeg)
V..... mpeg2_qsv MPEG-2 video (Intel Quick Sync Video acceleration) (codec mpeg2video)
V..... vp9_qsv VP9 video (Intel Quick Sync Video acceleration) (codec vp9)

@RangerWolf
同样的报错，也是说 some encoding parameters are not supported by the QSV runtime. Please double check the input parameters.
另外，我也查了，我的 CPU 是支持 QSV 的
https://www.intel.com/content/www/us/en/products/sku/212328/intel-celeron-processor-n5105-4m-cache-up-to-2-90-ghz/specifications.html

@ysc3839
@L4Linux
已经确认安装了 intel-media-sdk

[wapollo9]

或者能使用 VAAPI 实现 h264 转 hevc 也行
执行
ffmpeg -vaapi_device /dev/dri/renderD128 -i 1.mp4 -vf "format=nv12,hwupload" -map 0:0 -c:v hevc_vaapi -
map 0:a 2.mp4
的结果是

[hevc_vaapi @ 0x563cb06ea780] Failed to map output buffers: 24 (internal encoding error).
[hevc_vaapi @ 0x563cb06ea780] Output failed: -5.
Error submitting video frame to the encoder

[acreti]

ffmpeg -y -i input.mp4 -c:v hevc_qsv output.mp4

[ysc3839]

@wapollo9 VAAPI 好像不支持编码？
另外可以试试 GStreamer
https://gstreamer.freedesktop.org/documentation/msdk/index.html

我研究一下，谢谢！

[acreti]

你用的命令是什么？另外 yuvj420p 一般是给图片用的，视频用 yuv420p

[s7lx]

应该是 HuC/GuC 开启失败。N5105 N6005 都有这个问题。
sudo dmesg |grep i915 应该可以看到一个错误。
