Recorded video need in .mp4 format

[Banwari1990]

Hi,

Is it possible to get the recorded video in to .mp4 format instead of .webm format.

Thanks.

There's this solution using ffmpeg.js but that isn't optimal. But it also looks like, at least Firefox, can record as mp4, according to this example. I just tested this in Firefox 49 on Ubuntu and it did create a mp4 file:

started recording video stream
Using recorderType: MediaStreamRecorder
Passing following config over MediaRecorder API. Object { type: "video", mimeType: "video/mp4", initCallback: null }
Initialized recorderType: MediaStreamRecorder for output-type: video
Stopped recording video stream
video/mp4 -> 5.25 MB

I'll add an option to change the mimeType.

Edit: after checking the downloaded file it seems it's still a webm file 👎

Also tested on Chrome 54 / Ubuntu 16.04 and unfortunately it produced a webm vp8 file with mime type video/mp4. ffprobe details:

Input #0, matroska,webm, from 'recordrtc-chrome54.mp4':
  Metadata:
    encoder         : Chrome
  Duration: N/A, start: 0.000000, bitrate: N/A
    Stream #0:0(eng): Audio: opus, 48000 Hz, mono, fltp (default)
    Stream #0:1(eng): Video: vp8, yuv420p, 640x480, SAR 1:1 DAR 4:3, 30 fps, 30 tbr, 1k tbn, 1k tbc (default)

This is probably on hold until muaz-khan/RecordRTC#97 is resolved.

A full list of supported mime-types in Chrome is listed here. Just tested the mime type video/webm;codecs=H264 and it created a H264 clip. Output of ffprobe:

Input #0, matroska,webm, from 'index.mp4':
  Metadata:
    encoder         : Chrome
  Duration: N/A, start: 0.000000, bitrate: N/A
    Stream #0:0(eng): Video: h264 (Constrained Baseline), yuv420p, 640x480, SAR 1:1 DAR 4:3, 30 fps, 30 tbr, 1k tbn, 2k tbc (default)

Added audioMimeType and videoMimeType settings for H264 support in next release.

I've added:

videoMimeType: 'video/webm;codecs=H264'

under plugins.record. Is that all that is required? I haven't installed ffprobe, but should quicktime play the file I get from:

player.record().saveAs({'video': 'my-video-file-name.mp4'})

@smakinson should be enough, please open a new ticket if you see any issues.
