"video/mp4v-es"

Is it same as MPEG-4 part 2 (MPEG-4 Visual Format) codec format.

note : There is MPEG-4 part 10 format which is (H.264 )AVC Format. I just want need confirmation or any documentation or Blogs links which can help me in this.

Answer 1

Yes.

By default "video/mp4v-es" maps to the Google's MPEG4 Part-2 Video Software Codec. See media_codecs_google_video_xml for details. However on a real device, it will be implemented by a hardware video codec as software-video-codecs are processor-intensive.

For MPEG4 Part 10 (H.264), "video/avc" has to be used.
