[Automatic answer: RTFM (read DOCS, FAQ), also read DOCS/bugreports.html] Hi,
Out of curiosity, why are you using -forceidx with mencoder? It's almost never needed. In fact you can usually get by with -noidx when using mencoder unless you're using -ss or your file is badly damaged.
If the docs are suggesting -forceidx somewhere that should probably be removed... -forceidx forces rebuilding of the source file's index before starting on the encode/copy. A new working index is *always* generated for the output file regardless of whether you use -noidx/-idx/-forceidx.
not completely true. a new index is built, but the keyframe flags are recovered by -forceidx. ie, without it you'll get a correct stream, but with no frames flagged keyframe, so you cannot seek it. (streamcopy copies the frame flags (including keyframe marks) from the input stream, and for avi, it's located in index...)
IIRC you changed it so ALL frames are flagged keyframe without index... :) Rich
