如何从h264帧字节数据写出flv？

Question

我有一张抓取HDMI来源的捕获卡，此卡的SDK支持一个返回指向H.264帧 pbFrame <的指针的函数/ strong>和frame_info pbFrameInfo 。

SDK仅支持MP4个文件，但录制的文件非常重要，在任何情况下都不允许丢失，因此我需要FLV而不是{{1} }。

那么有没有办法使用MP4帧和frame_info存储FLV文件

更多信息：

• 分辨率= 1920 x 1080
• 帧持续时间= 381000
• 这是frame和frame_info转换为hex，frame的快照 不完整，因为它粘贴在这里很大：

第1帧

frame_info H.264
