avi to mov pipe to browser....?

[brownrl]

Ok

Here is one that should be fun!!!

I have an iPhone... ya ya I know enough already... No flash.

I also have an Ubuntu media center with a web server.

When I torrent an .avi movie I would like to be able to 'preview' it on my iPhone without using a flash thingy.

iPhone can play mov or mp4... streams...

So using either ffmpeg or mencoder I would like to read in the avi file and output as a mov file.

Lastly, I would like to do this in a PHP page...

So far I can convert the file to another file...

Not very helpful because then I have to wait for the conversion to happen completely. Also I don't see how to make ffmpeg output to a pipe. It has to be possible?

So I want to do something like this:


<?php

$file = "acitest.avi";

header( "YADA YADADA THIS IN AN MOV FILE..." );

passthru( "ffmpeg somestuff to convert $file to an mov" );

exit( 0 );
?>

try with this

ffmpeg -f mp4 -vcodec mpeg4 -maxrate 1000k -b 700k -qmin 3 -qmax 5 -bufsize 4096 -g 300 -acodec aac -ab 192k -s 320x240 -aspect 4:3 -i INPUT OUTPUT


some informationa bout bitrate and resolution can be found here
or googling

this one is for who has compiled ffmpeg ... if you have not compiled you have to change libx264 with h264 abd libfaac with aac

ffmpeg -i INPUT -r 29.97 -vcodec libx264 -s 480x272 -flags +loop -cmp +chroma -deblockalpha 0 -deblockbeta 0 -crf 24 -bt 256k -refs 1 -coder 0 -me umh -me_range 16 -subq 5 -partitions +parti4x4+parti8x8+partp8x8 -g 250 -keyint_min 25 -level 30 -qmin 10 -qmax 51 -trellis 2 -sc_threshold 40 -i_qfactor 0.71 -acodec libfaac -ab 128k -ar 48000 -ac 2 OUTPUT

close but not so close...

the ffmpeg must have a file output as it parameter...

In my case I don't want to output to a file....

I would like to output to the browser....
