Php fail converting avi to mp4
27 octobre 2013, par Dirk SwarzI'm able to convert video via server command using:
ffmpeg -i movie.avi -acodec libmp3lame -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 goodmovie.mp4For this test I used a 1.8mb video and after conversion it is 5 MB. I'm able to upload the video to my server after I download it from FTP and it will work with flash player, but when I try to automate this it fails.
CODE:
$ffmpeg_command = 'ffmpeg -i '.$new_name.' -acodec libmp3lame -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$anew_name; $convert_avi = true;It converts to MP4, but
it is not 5 MB but rather 2.2 MB when the original file is 1.8 MB
it doesn't play in flash player

ffmpeg ideal format to convert videos using ffmpeg
27 octobre 2013, par Offboardwell the thing is, I intend to do a conversion of videos in the following qualities 240p, 360, 480p and 720p
I researched a lot out there and got some codes to use, but there's something wrong some videos takes several hours to convert and shows this message.
[libvo_aacenc @ 000000000032a0a0] Bitrate 32 is extremely low, maybe you mean 32k The bitrate parameter is set too low. It takes bits/s as argument, not kbits/sbut some videos converts normally what I want is if someone has done some code that converts faster and is lighter in player jwplayer
ffmpeg -i discovery_channel.webm -ar 22050 -ab 32 -f mp4 -s 640x240 -preset ultrafast video240.mp4 ffmpeg -i discovery_channel.webm -ar 22050 -ab 32 -f mp4 -s 640x360 video360.mp4 ffmpeg -i FIDELIDADE.mp4 -ar 22050 -ab 32 -f flv -s 640x720 -preset ultrafast video720.mp4 ffmpeg -i FIDELIDADE.mp4 -s hd720 -c:v libx264 -crf 23 -c:a aac -strict -2 video720.mp4 ffmpeg -i discovery_channel.webm -s hd720 -c:v libx264 -crf 23 -c:a aac -strict -2 video360.mp4the last code I like most because it makes the conversion from vertical to 720 pixels, and does nothing in the horizontal video.
I tested several codes, when some take too much when video with the extension "webm"
anyway if someone has a good code that works in jwplayer and is unversão serves to any video.

video overwriting using ffmpeg - I want to Add video rotation code and rewrite the existing file..How can i do that ?
27 octobre 2013, par Lakshmi Priya.KI want to rotate the .mov file which is in portrait mode by 90 degrees, for that i used the following code.. It works but, it results in loss of video frames...
My code is,
public void encode(File source, File target, EncodingAttributes attributes, EncoderProgressListener listener, Integer i) throws IllegalArgumentException, InputFormatException, EncoderException { String formatAttribute = attributes.getFormat();

} target = target.getAbsoluteFile(); target.getParentFile().mkdirs(); FFMPEGExecutor ffmpeg = locator.createExecutor(); if (offsetAttribute != null) { ffmpeg.addArgument("-ss"); ffmpeg.addArgument(String.valueOf(offsetAttribute.floatValue()));

Converting avi to mp4 php fail

- it is not 5 MB but rather 2.2 MB when the original file is 1.8 MB
- it doesn't play in flash player.
The main upload script is in upload.php which anyone can download from here:

That code which i provided i just put into config.php

Jwplayer function snapshot using ffmpeg and php
27 octobre 2013, par Offboardbefore anything I'm using version 6, then the Snapshot plugin does not work.
I'm finally with 2 questions, take a sequence of photos of a percentage of the video, so googled it and got this code from ffmpeg:
ffmpeg -i video.mp4 -r 0.5 -f image2 output-%05d.jpegso far so good, but I do not know how to take a screen shot of the video by setting the time, if I'm right this code is per frame.
I searched again to get the function that calls the images, to generate good is quite simple, but the problem is that I found the pictures looks is all in one look.
if anyone has any function or know how to do please tell me: D My English sucks, so do not call if I messed up.
