ffmpeg ...“无法在筛选器支持的格式之间转换”
ffmpeg ...“无法在筛选器支持的格式之间转换”
提问于 2017-11-27 14:42:38
使用2017.11.26构建的最新ffmpeg master，我无法破译错误消息的含义，更重要的是，无法对它们做些什么。
从-vf更改为-filter_complex没有任何作用(我不得不尝试)。主要的错误信息似乎是
Impossible to convert between the formats supported by the filter我曾尝试在yadif和unsharp_opencl之前/之间/之后插入"format=“和"scale”，但都无济于事。
我想知道，这是不是与需要hwupload/hwdownload/hwmap有关，还是无关紧要？
我做错了什么？

不要紧。找到了有用的东西。例如
.\ffmpeg.exe -hide_banner -v verbose -init_hw_device
opencl=ocl:1.0 -filter_hw_device ocl -i
".\test_01.mpg" -an -map_metadata -1 -sws_flags
lanczos+accurate_rnd+full_chroma_int+full_chroma_inp -filter_complex
"[0:v]yadif=0:0:0,hwupload,unsharp_opencl=lx=3:ly=3:la=0.5:cx=3:cy=3:ca=0.5,hwdownload,setdar=dar=16/9"
-r 25 -c:v h264_nvenc -preset slow -bf 2 -g 50 -refs 3 -rc:v
vbr_hq -rc-lookahead:v 32 -cq 22 -qmin 16 -qmax 26 -coder cabac -movflags
+faststart -profile:v high -level 4.1 -pixel_format yuv420p -y
".\test_01.newest.MP4"为什么不..。您的设备id (例如上面的"1.0“)可以通过查看以下内容找到
.\ffmpeg.exe -hide_banner -v verbose -init_hw_device list
.\ffmpeg.exe -hide_banner -v verbose -init_hw_device opencl
.\ffmpeg.exe -hide_banner -v verbose -init_hw_device opencl:1.0 你可以从它们的选项中了解一下它们的特点：
.\ffmpeg.exe -hide_banner -v verbose -h encoder=h264_nvenc
.\ffmpeg.exe -hide_banner -v verbose -h filter=yadif
.\ffmpeg.exe -hide_banner -v verbose -h filter=unsharp_opencl 页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
