[FFmpeg-user] 0x0 is invalid and max_analyze_duration

[Cory J. Geesaman]

When I attempt to run:

 

ffmpeg -f mpegvideo -i http://localhost:8090/15.mpg -vcodec libvpx
http://localhost:8090/15_webm.ffm

 

to convert an mpegvideo stream into a webm stream I get the following error
and warning:

 

[mpeg1video @ 0x3901000] 0x0 is invalid

    Last message repeated 2 times

[mpegvideo @ 0x38f4f80] max_analyze_duration 5000000 reached at 5011633
microseconds

[mpegvideo @ 0x38f4f80] Estimating duration from bitrate, this may be
inaccurate

 

How do I get rid of this?
