Converting mp4 to ogg file format results in a large file
26 avril 2014, par paragsI have a MP4 file of 83MB (converted from MOV of about 772MB using FFMPEG).
For the file to be playable from all browsers from HTML5 video tag, I am converting the MP4 to OGG, again using FFMPEG commandffmpeg -i object-creation.mp4 -acodec libvorbis -vcodec libtheora -q:v 5 -q:a 5 object-creation-3.ogg
The result of the above command is a very large OGG file of around 500 MB. I would certainly not want to upload such huge files to Amazon S3 (which I am using for storage, and distribution).
Is there something I am missing here ? Is the file not compressed enough ?
Is it possible to have the resultant file of somewhat manageable size like 80-100 MB without any appreciable loss in quality over what is seen in MP4 format ? Why is it that even the source file is 83MB, the resultant file is too big in comparison ?
Thanks

A way to convert bitrate/format of audio files (between upload & storage to S3)
5 octobre 2011, par Jonathan CoeCurrently using PHP 5.3.x & Fedora
Ok. I'll try to keep this simple. I'm working on a tool that allows the upload & storing of audio files on S3 for playback. Essentially, the user uploads a file (currently only allowing mp3 & m4a) to the server, and the file is then pushed to S3 for storage via the PHP SDK for amazon aws.
The missing link is that I would like to perform a simple bitrate & format conversion of the file prior to uploading the file. (ensuring that all files are 160kbs and .mp3).
I've looked into ffmpeg, although it seems that the PHP library only allows for reading bitrates and other meta, not for actual conversion.
Does anyone have any thoughts on the best way to approach this ? Would running a shell_exec() command that performs the conversion be sufficient to do this, or is there a more efficient/better way of doing this ?
Thanks in advance ! Any help or advice is much appreciated.
