[FFmpeg-user] default mp4 encoding changed to x264

[Roger Pack]

Hello.
I noticed with this version of (windows) ffmpeg: N-31706-g335bbe4

And this command line:

$ ffmpeg -f dshow -i video=screen-capture-recorder  -r 5 -t 1 "yo3.mp4"

The output video encoding appears to default to

Output #0, mp4, to 'yo3.mp4':
  Metadata:
    encoder         : Lavf53.6.0
    Stream #0.0: Video: mpeg4, yuv420p, 500x500, q=2-31, 200 kb/s, 5 tbn, 5 tbc

However with this newer version: N-32138-g312645e

The output appears to default to:

Output #0, mp4, to 'yo3.mp4':
  Metadata:
    encoder         : Lavf53.10.0
    Stream #0.0: Video: h264 (![0][0][0] / 0x0021), yuv420p, 500x500,
q=2-31, 5 tbn, 5 tbc

(so newer one uses h264 instead of mpeg4 for default).
Is this change expected?
