谁能告诉我FFmpeg中所有AVCodec的pix_format支持? [英] who can tell me the support pix_format of all AVCodec in FFmpeg?

问题描述

像标题一样，我想知道FFmpeg中所有AVCodec的支持pix_format.

Like the title, I want to know the support pix_format of all AVCodec in FFmpeg.

像mpeg1video一样，我知道pix_format支持的只是PIX_FMT_YUV420P.那么其他AVCode呢?在哪里可以找到关于它们的定义?

Like mpeg1video, I know the pix_format which support is just PIX_FMT_YUV420P. So what about other AVCode? Where I can find the define about them?

谢谢.

推荐答案

针对单个编码器运行

ffmpeg -hide_banner -h encoder=encoder_short_name

例如

ffmpeg -hide_banner -h encoder=libx264

第四行将有

Supported pixel formats: yuv420p yuvj420p yuv422p yuvj422p yuv444p yuvj444p nv12 nv16 nv21

---

在bash上，您可以运行

On bash, you can run

for enc in $(ffmpeg -hide_banner -encoders | grep -i "V[\.|F]" | \
             cut -s -f3 -d" " | tail -n +2); \
do ffmpeg -hide_banner -h encoder=$(echo $enc) | grep "Encoder\|pixel" >> encpxfmt.txt; done;
