Hello, when I use them in FFMpeg version 4.4.4 and 5.1.2, I can never compile. I use MSYS2 compiled by msys2 in Windows.No, I think it's my problem?Will get the following errors:

Excuse me, thank you

有两处地方可能有问题，辛苦确认指正：
1）flv.h文件中，以下两个宏的定义：
#define EXT_HEADER_IS_KEYFRAME(x) (((x) & FLV_VIDEO_FRAMETYPE_MASK) == FT_KEY)
#define EXT_HEADER_IS_INTERFRAME(x) (((x) & FLV_VIDEO_FRAMETYPE_MASK) == FT_INTER)
应该是：
#define FLV_VIDEO_EXT_FRAMETYPE_MASK 0x70
#define EXT_HEADER_IS_KEYFRAME(x) (((x) & FLV_VIDEO_EXT_FRAMETYPE_MASK) == FT_KEY)
#define EXT_HEADER_IS_INTERFRAME(x) (((x) & FLV_VIDEO_EXT_FRAMETYPE_MASK) == FT_INTER)
2）flvenc.c文件中，flv_write_packet方法的1085行：
unsigned char is_key = (pkt->flags & AV_PKT_FLAG_KEY) ? FT_KEY : 0;
应该是：
unsigned char is_key = (pkt->flags & AV_PKT_FLAG_KEY) ? FT_KEY : FT_INTER;

谢谢

-f tee -map 0:v -map 0:a '[f=flv:flvflags=ext_header:onfail=ignore]rtmp://a.rtmp.youtube.com/live2/key1|[f=flv:flvflags=ext_header:onfail=ignore]rtmp://a.rtmp.youtube.com/live2/key2'

seems dint work

6.0 打入 patch 后，相同音视频编码内容的文件，使用 ffplay 播放，

codecid=12 规范的 FLV 文件可以正常拖动进度，
enhanced_rtmp 规范的 FLV (HEVC) 文件无法拖动进度，拖动时报错。

FFmpeg/tree/master 播放 enhanced_rtmp 规范的 FLV (HEVC) 文件 可以拖动。

官方 ffmpeg-6.1版本已经发布，
diff 看了一下，flv相关的三个文件都是有一定变化的

可否更新一下相应的三个文件，谢谢

I compiled ffmpeg with libx265 based on your instruction, but when I tried to push hevc stream through rtmp, I faced with this error;

[flv @ 0x563fe9051c80] Video codec hevc not compatible with flv
Could not write header for output file #0 (incorrect codec parameters ?): Function not implemented
Error initializing output stream 0:0 -- 

How can I send hevc stream by rtmp and flv?
thanks.

flv_write_packet里
if (par->codec_id == AV_CODEC_ID_VP6F || par->codec_id == AV_CODEC_ID_VP6A ||
par->codec_id == AV_CODEC_ID_VP6 || par->codec_id == AV_CODEC_ID_AAC ||
par->codec_id == AV_CODEC_ID_OPUS)
flags_size = 2;
else if (par->codec_id == AV_CODEC_ID_H264 || par->codec_id == AV_CODEC_ID_MPEG4 ||
par->codec_id == AV_CODEC_ID_H265 || par->codec_id == AV_CODEC_ID_VP8 ||
par->codec_id == AV_CODEC_ID_VP9) {

flags_size = 8;
} else {
flags_size = 5;
}
}
else
flags_size = 1;

如果是扩展rtmp头，flags_size是8为什么不是5
