Ffmpeg change height with fixed width
2 mars 2012, par DmitryI'm trying to change video dimensions using ffmpeg.
For example, user is uploading video 1280*960.And i need to get video 640*480 in return.
I tried this code and it works
exec($ffmpegPath." -i ".$srcFile." -ar 22050 -ab 32 -f flv -s 640x480".$destFile,$tmp);
but this method d't keep width/height balance of video (i.e. video 5000*480 becomes 640*480 and looks compressed from left and right).
In case of this dimensions (5000*480) i need to get video on exit like 640*61
i mean fixed height is not suitable for me.I look over the internet and found this topics
http://superuser.com/questions/201051/resize-videos-with-different-widths-to-a-fixed-height-preserving-aspect-ratio-wi
http://delogics.blogspot.com/2011/11/ffmpeg-maintain-aspect-ratio-with-fixed.htmlbut neither of them works for me (ffmpeg even not works with this code, maybe i've made mistake when adding theirs code parts in my ffmpeg string)
Help me to improve my code pls
Thanks

Transcoding wmv file to mp4 using Jave
17 mai 2013, par FawkesI am trying to use Jave to convert a wmv file into h264(mp4).
The final version created by Jave plays fine with VLC player but when I try to use it inside the HTML5 video tag, it is not able to play the file.I am guessing that the issue is with the attributes I am setting for the video attributes.
Java Code :
videoAttributes.setCodec("mpeg4");
videoAttributes.setTag("mpeg4");
videoAttributes.setBitRate(new Integer(5000));
videoAttributes.setFrameRate(new Integer(30));
videoAttributes.setSize(new VideoSize(512, 384));
encodingAttributes.setVideoAttributes(videoAttributes);
encodingAttributes.setFormat("mp4");HTML code :
<video controls="true" width="400" height="200">
<source src="path_to_converted_mp4_file" type="video/mp4"></source>
Not Supported
</video>
