I've been having problems serving videos from my dev server that play in mobile Safari. My dev server does not support the 'Accept-Ranges' header and after reading a few forums I've discovered that may be my problem. Here is an example forum posting saying just that.
Is this correct? Does mobile Safari require the Accept-Ranges header? Can anyone point me to any Apple documentation actually stating that?
Thanks.
I found some Apple documentation that says that it does in fact need that for video.
HTTP servers hosting media files for iOS must support byte-range requests, which iOS uses to perform random access in media playback. (Byte-range support is also known as content-range or partial-range support.) Most, but not all, HTTP 1.1 servers already support byte-range requests.
If you are not sure whether your media server supports byte-range requests, you can open the Terminal application in OS X and use the curl command-line tool to download a short segment from a file on the server:
curl --range 0-99 http://example.com/test.mov -o /dev/nullIf the tool reports that it downloaded 100 bytes, the media server correctly handled the byte-range request. If it downloads the entire file, you may need to update the media server.
