Adding srt support in php for mencoder

[Mysoogal]

For ISO 639 codes, have a look at this link.
For English, this is eng. So you could add the switch as -slang eng

Is it required to call flvtool2 with a pipe? Can we just call it after ffmpeg ?

In mencoder, you miss to put a quote before -subfont.

i've just tested this not seem to work , not really about flvtool2 dont think to much about it i was just wondering if it was going to work adding that | or && like in wget

it looks right to me any issues here

Code: Select all

$cmd = 'ffmpeg -i '.$in.' -f mp4 -vcodec -newsubtitle '.$in_sub.' -slang eng mpeg4 -r 25 -b 560000 -s 610x340 -acodec aac -ac 2 -ab 64 -ar 44100 '.$out_vid.  ;

Two issues.
1. Remove dot (.) before semicolon at the end of line
2. -vcodec mpeg4 should come together

Corrected line is given below.

i've done something dirty lol i used mkvmerge like this

Code: Select all

$cmd = 'mkvmerge -o '.$out_vid.' '.$in_sub.' '.$in.' ';

do the '.$in_sub.' need be changed like this '.$in_sub' without .dot ? confused here

[Neo]

No.it is correct to have a dot after $n_sub as there is a string to be concatenated after that.
You just need to understand that dot (.) is used to concatenate strings in php.

I do not see any problem there unless there is problem with flags. Just try to execute this in command prompt if possible.

[Mysoogal]

same return

strange i wonder if i can use another encoder such as avidmux but hmm maybe output mp4 not work in flash

[Neo]

Shall we rename your file name unidtf.xvid-lpd to a Sample. It can be that the ffmpeg is confusing with dash (-) in the file name.

[Mysoogal]

i've changed to example.avi and example.srt same return

i think it has something to do with audio i will look for more ffmpeg examples for mp4

[Neo]

In that case try, -acodec mpeg4aac instead of -acodec aac

[Mysoogal]

In that case try, -acodec mpeg4aac instead of -acodec aac

not even that seem to work

i try this one but not even this

Code: Select all

$cmd = 'ffmpeg -i '.$in.' -acodec libfaac -ab 128k -ac 2 -vcodec libx264 -vpre hq -crf 22 -threads 0 -newsubtitle '.$in_sub.' '.$out_vid; 

when i remove the

-newsubtitle '.$in_sub.'

it will encode to mp4 but when i try to add the subtitle section it doesnt encode video

ffmpeg with srt is not simple i hate ffmeg now

[Mysoogal]

ok do not worry about it, i do not need help with ffmpeg and srt i find out u can load srt inside flash player swf so its ok no need to encode it with video, but strange that is doesnt work.

thanks neo for your help again like always

by the way neo why don't you change bbcode so it has this automatically
