Hi Khan
Hope you are doing fine!!!

RecordRTC Video recording does not recording sound. Could you please help.

RecordRTC is "currently" incapable to record both audio/video streams in a single file format.

Is this lack of capability a problem with the API support in the browsers or it's just not been coded yet? If it's coding, what's needed on that side? 😄

There is no API available to record both tracks in a single Blob; or merge both Blobs to output a single WebM/MKV/etc.

MediaRecorder API is in discussion and early implementation process; these APIs are planned to output a single Blob for one or more streams.

Currently stream-processing API doesn’t allow merging of both audio/video streams directly inside the browser’s context. That’s why developers starting using server side solutions like ffmpeg/avconv (PHP) etc (or media-server).

Currently, RecordRTC returns unique Blob for each track. An array-buffer/unit8array option is also there; you may be able to merge two arrays to output a single Blob.
