Hi, An update on the streaming feature in MediaPlayer. The MediaPlayer / VideoView only support "progressive streamable contents", which has to satisfy two criterion: 1. the movie atom has to precede all the media data atoms; 2. the clip has to be reasonably interleaved;
Here is a simple way to tell whether a file is "progressive streamable contents" type of content. If there are any "mdat" string before "moov" string, then it is NOT progressive streamable contents. (As shown in the examples here) *Not progressive streamable content:* $ strings /tmp/3.3gp |grep -n "mdat\|moov" 16:mdat 17:mdat 18:mdat 2278:WHmdat<c 2617:moov * Progressive streamable content:* $ strings /sdcard/box.mp4 |grep -n "mdat\|moov" 3:#moov 99:mdat 101:mdat A following test URLs that I received from this group earlier are not Progressive Streamable Content. 1) http://download-v5.streamload.com/x7Hxsaah~FI2O~568g~4Vxg~KO4LKISs-nrA/gonefishing7/FileManager/Monty.mp4<http://www.google.com/url?q=http%3A%2F%2Fdownload-v5.streamload.com%2Fx7Hxsaah%7EFI2O%7E568g%7E4Vxg%7EKO4LKISs-nrA%2Fgonefishing7%2FFileManager%2FMonty.mp4&sa=D&sntz=1&usg=AFQjCNFEdWmb5kUbF0I9U5TlOBD2bwJFIQ> 2) http://www.daily3gp.com/vids/3.3gp<http://www.google.com/url?q=http%3A%2F%2Fwww.daily3gp.com%2Fvids%2F3.3gp&sa=D&sntz=1&usg=AFQjCNH6ercYzj5QVLs3PEee9NxqP2vvrA> Thanks, Megha On Sat, Mar 22, 2008 at 2:54 PM, Megha Joshi <[EMAIL PROTECTED]> wrote: > Hi, > > Streaming does not work for certain mp4 URLs that I got from this forum.
