Description

Saved a wmv movie from a website, want to use it as h.264 mp4 file. Regardless of commandline options (-analyzeduration included), I am not able to convert. Leaving off the output file, all output looks good until it says it needs at least one output file to proceed. Once that is given, message "swScaler: Unknown format is not supported as input pixel format - Cannot get resampling context" is given. Tried outputting to different formats, all same result. Running on Red Hat 5.4 64-bit server as root and even chmod 777'd the input file, no change. Running ffmpeg 0.6.5. Tried yum install *ffmpeg* and yum update *ffmpeg* to make sure I had all dependencies at the latest rev. Same message every time. Output below, input video attached. For the record, the input videos plays perfectly on every media player I've tried.

"ffmpeg -v 9 -loglevel 99 -i" output:

comment:1 Changed 6 years ago by themikeybee

My apologies, this is my first bug on here, and i don't think I'm doing this right, but the modify button doesn't let me edit my post. At any rate, the original input file was about 13 megs, but the attach page only lets me go up to 2.5, so I dd'd a 2.5 meg copy (now attached). I did re-run my testing to see if the smaller file size would change anything, and it did not.
