I am using simple HTML5 audio tag. For .mp3 file it is working fine.
But I want to play .3gp file.
<audio controls>
<source src="horse.ogg" type="audio/ogg">
<source src="horse.mp3" type="audio/mpeg">
</audio>
Browsers support only limited audio formats. see
3GP files are not playable in all browsers. Convert 3GP files to MP3 files, for example using Audacity audio editor.
You have to use video tag for video, because 3gp is a video extension.
<source
src="video.3gp"
type='video/3gpp; codecs="mp4v.20.8, samr"'>
</source>
