Comment (by fthiery):

 -fflags +genpts not working for me, ffmpeg still duplicating frames by the
 thousands.

 {{{
 $ ffmpeg -fflags +genpts -i input.webm output.mp4
 ...
     Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p,
 1280x720 [SAR 1:1 DAR 16:9], 2049 kb/s, 1k fps, 1k tbr, 16k tbn, 2k tbc
 (default)

 }}}
