FFMPEG HLS多音频语言，带有var_stream_map-EXT-X-MEDIA:TYPE donds'；不包含语言,ffmpeg,Ffmpeg,我有一个问题涉及使用FFMPEG的HLS上的多种音频语言我目前正在使用以下命令将具有多种音频语言的传输流多路复用到具有主播放列表的HLS流中： ffmpeg -re -i $INPUT_URL -map 0:v -c:v copy -map 0:a -c:a copy -f hls -hls_time 6 -hls_list_size 10 -hls_flags delete_segments+program_date_time -hls_segment_filename "$FULL_OUT

我有一个问题涉及使用FFMPEG的HLS上的多种音频语言

我目前正在使用以下命令将具有多种音频语言的传输流多路复用到具有主播放列表的HLS流中：

ffmpeg -re -i $INPUT_URL -map 0:v -c:v copy -map 0:a -c:a copy -f hls -hls_time 6 -hls_list_size 10 -hls_flags delete_segments+program_date_time -hls_segment_filename "$FULL_OUTPUT_FOLDER/stream_%v_%d.ts" -var_stream_map "v:0,agroup:groupname a:0,agroup:groupname a:1,agroup:groupname a:2,agroup:groupname a:3,agroup:groupname" -master_pl_name master.m3u8 $FULL_OUTPUT_FOLDER/stream-%v.m3u8

此命令的输出如下所示：

虽然这似乎对VLC有效，但我需要EXT-X-MEDIA:TYPE标记来包含LANGUAGE属性。（我正在使用的播放器使用它来解析音轨的语言）根据我找到的文档，我不知道该怎么做

有人能帮我吗

谢谢

看了源代码后，我发现这根本不受支持（还没有？）

在代码中可以找到以下函数：

[libavformat/hlsenc.c]创建主播放列表

[libavformat/hlsplaylist.c]ff_-hls_-write_-audio_-rendition

当查看这些实现时，您可以看到LANGUAGE属性实际上从未被输出

因此，这意味着我必须找到另一种方法来实现这一点。

以下示例可能会对您有所帮助

我已将第一个音频流分配给英语，第二个分配给意大利语，第三个分配给法语

-var\u stream\u map“v:0，agroup:groupname a:0，agroup:groupname，语言：英语a:1，agroup:groupname a:2，agroup:groupname，语言：ITA a:3，agroup:groupname，语言：FRA”

参考第4.13.1节，在“变量流图”下

在trac.ffmpeg.org上提交报告，谢谢您的建议。我已经向邮件列表发送了一个补丁来实现它。我希望它能被接受。补丁被接受了吗？或者以其他方式解决？
