尝试使用英特尔 quicksync 的 ffmpeg，“初始化编码器时出错：无效的视频参数 (-15)

Question

我经常不使用英特尔 quicksync 来执行 ffmpeg，例如创建一个名为“a”的子目录，ffmpeg -i IMG_0001.MOV -c:a libmp3lame -c:v libx264 -preset ultrafast ffff.mp4

（我知道 mp4 容器中的 mp3 有点过时，而 aac 是当前的惯例/标准，但我的旧视频编辑器不喜欢其中的 aac。我知道 libx264 现在质量有点低，但对我来说没问题，我不认为这是问题的根源）

我想尝试使用英特尔快速同步进行编码，因为我知道它速度更快。

我使用的笔记本电脑上的处理器是 i5 3230m，支持 quicksynchttps://ark.intel.com/content/www/us/en/ark/products/72056/intel-core-i53230m-processor-3m-cache-up-to-3-20-ghz-bga.html

我执行命令ffmpeg -i IMG_0030.MOV -acodec copy -vcodec h264_qsv blah.mp4

但我得到了错误

[h264_qsv @ 00000000004ddd40] Error initializing the encoder: invalid video parameters (-15)
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width
or height
Conversion failed!

还

我注意到 h264_qsv 已列出，ffmpeg -encoders我猜这可能意味着 ffmpeg 构建支持它

添加

以下是使用此命令的尝试，因此，指定 crf，正如评论所建议的那样ffmpeg -i IMG_0001.MOV -c:a copy -c:v h264_qsv -crf 23 aaa.mp4

它用青色显示“[h264_qsv @ 00000000003804c0]”，后面跟着红色的“[h264_qsv @ 00000000003804c0] 初始化编码器时出错：视频参数无效 (-15) 初始化输出流 0:0 时出错 -- 打开输出流 #0:0 的编码器时出错 - 可能是比特率、速率、宽度或高度等参数不正确”

然后出现灰色的“转换失败！”，如下所示

如果我将 -c:a copy 更改为 -c:a libmp3lame，那么我也会收到此消息，尽管在 yelloe 中“为输出文件 #0 (aaa.mp4) 指定的 Codec AVOption crf（选择恒定质量模式的质量）尚未用于任何流。最可能的原因是类型错误（例如，没有视频流的视频选项）或它是某个编码器的私有选项，实际上并未用于任何流。”。当我不指定 -crf 时，我不会收到该消息。
