[FFmpeg-user] Playback problems for video compressed as lossless H.264

Hi,
I'm compressing a video with ffmpeg and libx264. I want lossless compression:
ffmpeg -i h.264/00.mp4 -vcodec libx264 -g 30 -qmax 0 -y bad.mp4 > bad.txt 2>&1
If I try to play back the file in any standard video player (e.g.
VLC), then the video does not play back smoothly, and many frames are
just gray. Strangely, in ffplay, it seems to work just fine.
If I use lossy compression:
ffmpeg -i h.264/00.mp4 -vcodec libx264 -g 30 -y good.mp4 > good.txt 2>&1
then things work fine.
What could be the problem? I can provide the test media if required.
My version of ffmpeg is N-42806-gf4451d2.
Cheers,
Misha
