[FFmpeg-user] ffmpeg & ffplay produce gray frames from h264 input

[Chris Herdt]

I have a series of raw h264 files that I have been attempting to
convert to mp4 using ffmpeg. Most work, but some produce solid gray
frames part way through (and then on to the end of the video).

I tried playing the videos using ffplay, and they also produce gray
frames in playback. The videos do play back on the recording device,
but it's a proprietary system so I don't know much about them beyond
that they are h264 files.

Here's the ffplay command & output:

ffplay -f h264 ../testch00000000000001-120217-121829-121829-10p001000000.264
