http live streaming ,m3u8 文件有没有开源的解析代码？

[LENOVO_]

近日需要用到这个功能，但是m3u8 是 m3u 的扩展，有EXT-X-STREAM-INF 这个字段，
是另一个 m3u8文件的地址，也就是说编程的话要递归进去。

需要用 C 语言完成这个功能，我看到这个是 java 实现的。

我查找 vlc 的代码里面只有解析 标准 m3u 文件的代码
只有 对 #EXTINF 进行了处理。

//Open and parse a M3U file:
int M3U_open(char *fileName){
	FILE *f;
	char lineText[512];
	char chrLength[20];
	char title[264];
	struct M3U_songEntry *singleEntry;
	int playListCount = lPlayList.songCount;

	f = fopen(fileName, "rt");
	if (f == NULL){
		//Error opening file:
		return(-1);
	}

	while(fgets(lineText, 256, f) != NULL){
		if (!strncmp(lineText, "#EXTINF:", 8)){
			//Length and title:
			splitSongInfo(lineText, chrLength, title);
		}else if (!strncmp(lineText, "#EXTM3U", 7)){
			//Nothing to do. :)
		}else if (strlen(lineText) > 2){
			//Store song info:
			singleEntry = &lPlayList.songs[playListCount++];
			strncpy(singleEntry->fileName, lineText, 263);
			singleEntry->fileName[263] = '\0';
			if ((int)singleEntry->fileName[strlen(singleEntry->fileName) - 1] == 10 || (int)singleEntry->fileName[strlen(singleEntry->fileName) - 1] == 13 ){
				singleEntry->fileName[strlen(singleEntry->fileName) - 1] = '\0';
			}
			if ((int)singleEntry->fileName[strlen(singleEntry->fileName) - 1] == 10 || (int)singleEntry->fileName[strlen(singleEntry->fileName) - 1] == 13 ){
				singleEntry->fileName[strlen(singleEntry->fileName) - 1] = '\0';
			}

			if (strlen(title)){
				strncpy(singleEntry->title, title, 263);
			}else{
				getFileName(singleEntry->fileName, singleEntry->title);
			}
			singleEntry->title[263] = '\0';
			singleEntry->length = atoi(chrLength);
			if (playListCount == MAX_SONGS){
				break;
			}
		}
	}
	fclose(f);

	lPlayList.modified = 0;
	lPlayList.songCount = playListCount;
	strcpy(lPlayList.fileName, fileName);
	return(0);
}

我想有没有同学可以提供下 C 语言实现的开源库地址，我拿来用用。

你可以看看ffmpeg里面有没。

ffmpeg 没去看，细挑起来太过复杂。

找到个

httplive.c: HTTP Live Streaming stream filter

里面有解析的代码，嵌套地址的事情我自己处理下。

楼主实现了吗
