ffmpeg has trouble with the 1080p60 (yes, progressive 60 fps) format as produced by the Sanyo VPC-FH1 camera.  The first second of footage is corrupted as if the first I-frame was skipped, but the P-frames were decoded.  It also produce a large number of messages of the form:

[mov,mp4,m4a,3gp,3g2,mj2 @ 0xe35360]Invalid timestamps stream=0, pts=0, dts=1001, size=136
[mov,mp4,m4a,3gp,3g2,mj2 @ 0xe35360]Invalid timestamps stream=0, pts=2002, dts=3003, size=25016
[mov,mp4,m4a,3gp,3g2,mj2 @ 0xe35360]Invalid timestamps stream=0, pts=4004, dts=5005, size=30896
[mov,mp4,m4a,3gp,3g2,mj2 @ 0xe35360]Invalid timestamps stream=0, pts=6006, dts=7007, size=31912

Converted footage looks fine after that first second, and sound is in sync throughout.  I've tested all of the camera's formats, and only 1080p60 exhibits this problem.

I've uploaded a brief sample that demonstrates the problem.  The file is named:

    SANY0267.MP4

ffmpeg and ffplay (SVN-r19609), mplayer, and VLC all show the same problem.  You can see it by using any of those players, or you can convert the file with this command:

    ffmpeg -i SANY0273.MP4 -target ntsc-dvd 273.mpeg

then use any player to see the result.
