My Http Live Streaming setup: Apache hosts the html, m3u8, and ts files
The ts files are copied over from http:devimages.apple.com/iphone/samples/bipbop/gear1/fileSequence*.ts. There is nothing wrong with the video encoding (verified by actually playing these files)
m3u8 files (both the multi-bitrate and leaf-level) are copied over from apple's example and are syntactically correct, as follows:
#EXTM3U
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:10, no desc
fileSequence0.ts
...
#EXTINF:1, no desc
fileSequence180.ts
#EXT-X-ENDLIST
videoplay.html (below) fails to stream the video from my apache server
<video src="bipbop/bipbopall.m3u8" controls autoplay ></video>
However on modifying videoplay.html (below), the video streams just fine from Apple's website
<video src="http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8" controls autoplay ></video>
I suspected something wrong with mime type settings because Chrome was handling http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8 and http://localhost/bipbop/bipbopall.m3u8 differently. While Chrome tries to play the former, it downloads and saves the latter one. So I double checked my mime type setting, which is set as below in my httpd.conf
AddType application/x-mpegURL .m3u8
AddType video/MP2T .ts
- Is my mime type setting correct?
- How do we figure the mime type association advertised by apple's website?
- Or do we have to look elsewhere to fix this?
回答1:
This might seem strange but I also faced similar problems, and after much debugging I found that empty lines in the .m3u8 index file can cause such issues. Please double check for empty lines in your index file.

According to the HLS rfc documentation you should use "application/vnd.apple.mpegurl" or "audio/mpegurl" but you could also simply make the path end with .m3u8 or .m3u.
Each Playlist file MUST be identifiable either by the path component of its URI or by HTTP Content-Type. In the first case, the path MUST end with either .m3u8 or .m3u. In the second, the HTTP Content-Type MUST be "application/vnd.apple.mpegurl" or "audio/mpegurl". Clients SHOULD refuse to parse Playlists that are not so identified.

Bit late, but for clarity's sake:
File extension | MIME type
-------------------------------------------------------------
.M3U8 | application/x-mpegURL (or vnd.apple.mpegURL)
.ts | video/MP2T
