ubuntu下，我用.h264轉(zhuǎn)換.mp4格式提示一下信息：
ffmpeg -i 1e1fee9790f26fa3_202214225310.h264 -vcodec copy -f mp4 test.mp4

這個(gè)也不算個(gè)錯(cuò)誤，就是個(gè)警告，如果想消除可以這樣
ffmpeg -i 1e1fee9790f26fa3_202214225310.h264 -vcodec copy -flags +global_header -f mp4 test.mp4

加上-flags +global_header，就不會(huì)報(bào)提示了

參考文章1：加密的m3u8、ts文件合并

參考文章2：ffmpeg 處理輸入 h264 到 h265 時(shí)發(fā)現(xiàn)無效數(shù)據(jù)

總結(jié)

以上是生活随笔為你收集整理的ffmpeg：Codec for stream 0 does not use global headers but container format requires global headers的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
