Here's my response to the same suggestion from Rodger above: "We could speculatively move all entries based on the first insert and total entries count, but their are several conditionals in av_add_index_entry() which may cause a bail out and such failure would be unrecoverable (maybe painfully?) if we moved everything ahead of time." - dale _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
