[Ffmpeg-devel] x264: AVI index broken

After encoding a file with this command:
ffmpeg -i $1 -f avi -vcodec h264 -b $VBITRATE -s 640x480 -acodec mp3
$OUTFILE
I get this file:
$ tcprobe -i ffmpeg-715.avi
[tcprobe] RIFF data, AVI video
[avilib] V: 29.970 fps, codec=H264, frames=3446, width=640, height=480
[avilib] A: 32000 Hz, format=0x55, bits=0, channels=2, bitrate=64 kbps,
[avilib] 3196 chunks, 920448 bytes, VBR
[tcprobe] summary for ffmpeg-715.avi, (*) = not default, 0 = not detected
import frame size: -g 640x480 [720x576] (*)
frame rate: -f 29.970 [25.000] frc=4 (*)
audio track: -a 0 [0] -e 32000,0,2 [48000,16,2] -n 0x55 [0x2000] (*)
bitrate=64 kbps
length: 3446 frames, frame_time=33 msec, duration=0:01:54.981
When I start VLC (nightly build amd64 0.8.5-svn20060212-0), I get this
error:
"This AVI file is broken. Seeking will not work correctly. Do you want
to try to repair it (it might take a long time)?"
If I say yes, I get this:
[00000290] avi demuxer debug: Fixing AVI index
[00000290] avi demuxer warning: creating index from LIST-movi, will take
time !
The file repairs and plays fine -- though I should mention the file
plays just as well if I respond no. Alternatively, I can read it into
avidemux and save it straight; that fixes the problem permanently.
Resulting files stream great with VLC.
Questions:
Am I leaving out a command parameter?
Is this a bug I should report?
Is there a workaround that can be scripted -- rebuilding the avi index?
This looks like a minor issue in a system that is basically working
extremely well -- fantastic work!
