篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了FFmpeg报错：Specified pixel format yuvj420p is invalid or not supported（用ffmpeg程序查看编码器支持像素格式命令）相关的知识，希望对你有一定的参考价值。
文章目录
原因
这是因为我们把海康rtsp视频流packet解封装后，它frame的像素格式是yuvj420p（AV_PIX_FMT_YUVJ420P）的，然后我们又指定编码器上下文的像素格式pix_fmt = AV_PIX_FMT_YUVJ420P，指定编码器为AV_CODEC_ID_MPEG4，但是AV_CODEC_ID_MPEG4不支持AV_PIX_FMT_YUVJ420P像素格式，所以报了上述错误
解决办法
用ffmpeg -h encoder=mpeg4指令查看编码器支持哪些像素格式
发现：
x264编码器支持yuv420p yuvj420p yuv422p yuvj422p yuv444p yuvj444p nv12 nv16 nv21 yuv420p10le yuv422p10le yuv444p10le nv20le gray gray10le
x265编码器支持yuv420p yuvj420p yuv422p yuvj422p yuv444p yuvj444p gbrp yuv420p10le yuv422p10le yuv444p10le gbrp10le yuv420p12le yuv422p12le yuv444p12le gbrp12le gray gray10le gray12le
mpeg4编码器支持yuv420p
那么解决方法只能是
①将yuvj420p的frame转换成yuv420p的frame，再输入给mpeg4编码器（我不知道ffmpeg有没这个功能。。。）
②换个编码器，比如x264或x265，它们都支持解析yuvj420p，同时能将输出packet的像素格式转换成其他的类型，比如yuv420p
