总是卡在上面这里（设置为使用cpu软件来编码）

2。 另外，我发现只有将encoder设置为cpu才可以达到上面这里 我是intel集成显卡，试了vaapi、qsv等，都报以下错误，似乎还不如上面

@garywill 您是否使用了虚拟机或是WSL？据我所知i3-3110M应该支持Intel QSV

garywill commented 7 months ago

没有用任何虚拟或容器，实机linux

前段时间我这里试过其他软件vaapi转视频，是可以的

我觉得是否qsv不是重点，现在是使用cpu软编都不行 能解决我汇报的第1点的话，就至少还能用

Vinlic commented 7 months ago

@garywill 使用了哪个Linux发行版，我需要复现一下它

garywill commented 7 months ago

opensuse 15.5

大哥辛苦了～

Vinlic commented 7 months ago

@garywill 好的，我可能需要花一些时间去验证，目前在ubuntu未发生这样得问题。

garywill commented 7 months ago

呃等下。。 我原本是把duration改成了300想减少点试试（fps也降低） 好像改回readme中的10000后可以了。duration至少400才可以。。。。 还和fps与duration和互相组合有关

不过qsv和vaapi还是不行

Vinlic commented 7 months ago

@garywill 好的，这里的时间是毫秒，确实缺少对于超短时长的测试，我会在今晚验证一下 至于qsv的调用问题，您能否在命令行使用ffmpeg尝试一下使用h264_qsv转码一个mp4文件来检查一下 或者用wvc.config({ ffmpegDebug: true })，打开ffmpegDebug选项输出ffmpeg执行的命令

Vinlic commented 7 months ago

@garywill 针对第一个问题，在短时长低帧率的时候，例如300毫秒 15fps时，视频只有4帧，4帧不足以填满缓冲区，导致缓冲区拼接异常。 已经修复，将会在接下来的0.0.31版本更新。 修复缓冲区存在空帧时无法拼接的问题

Vinlic commented 7 months ago

你可以通过以下命令验证您的qsv编码器是否工作，需要先安装好ffmpeg 😸 ： ffmpeg -i input.mp4 -c:v h264_qsv out.mp4 @garywill

garywill commented 7 months ago

加了ffmpegDebug: true后并没有增加什么输出信息

我看了下node_modules里的静态ffmpeg文件，列出的编码器里没有qsv或vaapi，估计是这个原因

（而我系统里的ffmpeg列出的是，有vaapi，无qsv）

而在上面表中，我看见了v4l2，下次我尝试下

以及我的系统里和驱动方面的，晚上我再尝试

Vinlic commented 7 months ago

@garywill 这确实不太正常，我在windows系统上测试，ffmpeg-static内的二进制文件输出了h264_qsv，我觉得可能和ffmpeg-static的下载来源有关，晚些我会调查一下。

garywill commented 7 months ago

猜测他们的静态编译是不是阉割了linux的硬件加速 linux的发行版众多，涉及显卡等硬件的，做静态可能难一点

我觉得作为workaround，你可以允许用户指定ffmpeg路径

Vinlic commented 7 months ago

@garywill 其实是可以指定的

wvc.config({
    ffmpegExecutablePath: "..."
});
garywill commented 7 months ago

qsv没有成功，但vaapi在系统中成功~!

需要添加一些vaapi需要的ffmpeg选项，并不是只设个-c:v就行的。 我使用以下命令成功在系统里做vaapi转换

ffmpeg  -hwaccel vaapi   -i  input.mkv  -vf 'hwupload'  -acodec copy  -vcodec h264_vaapi output.mp4

我是参考这里的 https://gist.github.com/Brainiarc7/95c9338a737aa36d9bb2931bed379219 ， 他推荐的命令是

ffmpeg -loglevel debug -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i "input
file" -vf 'format=nv12,hwupload' -map 0:0 -map 0:1 -threads 8 -aspect
16:9 -y -f matroska -acodec copy -b:v 12500k -vcodec h264_vaapi
"output file"

WVC里，先指定了使用系统的ffmpeg，没有再提示找不到h264_vaapi。 但有新的报错

感觉现在只需要WVC能够设置成使用-hwaccel vaapi -i input.mkv -vf 'hwupload' 这样的参数运行ffmpeg

那么，命令参数能自定义的吗？

Vinlic commented 7 months ago

@garywill -hwaccel实际上指定的是硬件解码器，WVC只用到硬件编码器，所以应该使用-c:v

garywill commented 7 months ago

-hwaccel实际上指定的是硬件解码器

可能ffmpeg的编码和解码器的组合还是有讲究的， 我这里试验的结果是， 只有在这三个选项都有的情况下，才能使用vaapi而不报错：

  1. -hwaccel vaapi
  2. -vf 'hwupload'
  3. -vcodec h264_vaapi (-vcodec和-c:v是同样意思的吧）
Vinlic commented 7 months ago

@garywill 您在本机的ffmpeg试验过-vcodec h264_qsv吗，qsv的硬件加速应该更好，vaapi是Linux所支持的。

garywill commented 7 months ago

您在本机的ffmpeg试验过-vcodec h264_qsv吗

试过，不成功。按照网上的教程，除了-vcodec h264_qsv，还要加其他选项的，但我这里尝试了都报错

Vinlic commented 7 months ago

@garywill 尝试这个版本是否可用： https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-amd64-static.tar.xz 我在centos可以正常调用qsv

garywill commented 7 months ago

尝试这个版本是否可用：https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-amd64-static.tar.xz

在我这里不行。。 ./ffmpeg -encoders列出的里面，无qsv，无vaapi

Vinlic commented 7 months ago

@garywill 那也许真的和系统驱动相关，或者可以试一下这个方案： https://en.opensuse.org/FFmpeg

I have the same error, how do I fix it?

Vinlic commented 6 months ago

@thanhtoan1196 Please provide the calling code and error information so that we can investigate the cause. 😄
