I ran into this issue recently, my solution was to add the src attribute directly onto the <video> element. Like

<video src="-base64 string here-" width="xx" height="yy">
    Your browser does not support HTML5 video.
</video>

adding the src in the <source> element caused the video to do nothing.

"...But video is not getting played. i am not able to trace it, can any one help me?"

(1) Your string "AAAAGGZ0eXBtcDQyAAAAAG1wNDFpc29tBNjldm1kYXQAAAAAAAAAEAA=" only provides 41 bytes. This is not enough to play a video.

00 00 00 18 66 74 79 70 6D 70 34 32 00 00 00 00         ....ftypmp42....
6D 70 34 31 69 73 6F 6D 04 D8 E5 76 6D 64 61 74         mp41isom.Øåvmdat
00 00 00 00 00 00 00 10 00                              .........

(2) Your bytes begin with mdat (which is a/v data all mixed up in one group), the decoder needs moov part of file (which has metadata) to know where frame1 bytes begin/end within all that mixed mdat section. Best to make MP4 file with moov first, followed by mdat.

Find fixing tool online with keywords : fast start MP4 moov at front

(3) Because mdat is first, we can see its size at bytes : 04 D8 E5 76 (which means 81.3 MB). So you must receive around 81 megs before you even begin having metadata for decoder.

Decoder needs metadata (stored in moov section, after 81 megs of this mdat) before it can display anything or decode sound.

yes my response was not got encoded properly into the base64 value it was short and not valid one
