Hello, In attach new patchs for showvolume filter
001 : Move the clear picture part to a new func, and use it if fade option == 0. (no need to calculate it in float) 002/003 : Move "height" condition for draw volume at the start of the loop and indent 004 : add a new option for choosing the display scale currently, the filter use linear display, most audio meter use some kind of log display 005 : WIP : The idea is to add an option to draw a line for the max level for a given duration. Several audio meter have this kind of display, and its help user, to check peak level (even if the "peak" happen during a very short time. I'm not entirely sure, this is the best way to add this. For now, i store the max value for each channel, update it, if a new peak is bigger than the store value And count the number of frame for display. If a given display duration is exceed, update the max value to the current max value. Missing docs and probably code reorganization to reduce code duplication. I also have had very few inspiration for option naming and variable naming (and i don't know the "official name" of this little line in audio meter). So i'm open to better naming suggestion. This display need to be enable using dm=1 and the duration during the max value is still display can be set with dm_duration (in seconds) Comments welcome Martin
