XFileSharing Pro - MP4 Moov Atom

[speakerbox]

Where can I specify where mp4 box places the moov atom as at this time it takes a while for the initial MP4 videos to start playing. The video begins downloading quickly right away and downloads roughly 8 percent before it begins to stream in our player; We'd prefer that it starts after 1 or 2 percent.

Thanks!!

I do not believe this functionality has been implemented yet. However, if you want to do it yourself you should use:

Code: Select all

MP4Box -inter 500 filename.mp4

I made some changes to the enc.pl file how-ever it doesn't seem to change where the moov atom is placed.

Code: Select all

    my @rr = `/usr/bin/MP4Box -add $c->{upload_dir}/$dx/$code.mp4 -isma -inter 500 $c->{upload_dir}/$dx/$code.mp4x`;
    #my @rr = `/usr/local/bin/MP4Box -add $c->{upload_dir}/$dx/$code.mp4 -isma -inter 500 $c->{upload_dir}/$dx/$code.mp4x`;

I also tried 100 but it didn't have an affect.

You are already using the -isma parameter which makes the -inter parameter obsolete. Both parameters do its job just fine and because of that I think your problem has nothing to do with file's moov atom at all.

Do you have an example link?

[speakerbox]

The -isma parameter doesn't affect the -inter parameter.

I can show you an example - whats your contact information?

[komi]

As far as I know -isma already moves the moov atom to the beginning, without the -inter parameter.

Sorry cannot share contact information.

Does anyone else have any suggestions for this? I guess my other option is pseudo streaming.

Without an example link, it is hard to determine where the problem is.

Also you might want to use H264 Streaming Module (http://h264.code-shop.com/trac).

use ffmpeg's qt-faststart after making the mp4

Also try to change streamer value in player code to http instead of file by default. It's in index_dl.pm I think.

and to be able to play at start with out all those modifications is it even better to install psuedostreaming ( H264 pseudostreaming)

it is a mess to get the player working for it , but as soon it is fixed then it will work

lets explain what that is
pseudostreaming loads the end of the file first to know the size of the video and then use keys to say his position

on that way you can skip parts of a movie and play it with out a problem
as it does not need to load the video to play

here is a previeuw

and if you like to know the size , it is 2.3GB
this is what you get as normal user
5040231.mp4.mp4 - 44.4 MB

I changed the values for the player to a 3 second buffer - the flash files start more quickly but the mp4 files are the same.

The main issue is that large files take over a minute to start playing. The moov atom is a certain percent into the video file so it works ok for smaller files.

I tried the psudostreaming with nignx and I couldn't seem to compile nginx to make it work.

I'll keep looking around for a solution.

Any idea how to do this? Do not have much experience with editing enc.pl file.
Thanks in advance
