#61(avfilter:new): ability to read video size during filtergraph operation

#61: ability to read video size during filtergraph operation --------------------------+---------------------- Reporter: nieder | Owner: michael Type: enhancement | Status: new Priority: wish | Component: avfilter Version: git | Keywords: Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 --------------------------+---------------------- While running a video through a filtergraph, I needed to know the size of the video. However, I could not find a way to read the size of the video at that point in time. {{{ -vf "scale=${OUTWIDTH}:-1 [small] ; movie=${WATERMARK_FILE} [wm] ; [small][wm] overlay=main_w-overlay_w-10:10 [tagged] ; [tagged] pad=${OUTWIDTH}:${OUTHEIGHT}:0:(${OUTHEIGHT}-in_w)/2" }}} This is the filtergraph I was using. My goal is to take several videos with different sizes and aspect ratios, shrink them all to a fixed width, and then add padding as necessary to give them all the same height. Because the scaled video will have varying height dimensions, I need to determine the height value before I can calculate the padding value. The 'crop' filter has "in_w" and "in_h" to provide the current values of the video, but these parameters don't seem to be available in the 'pad' filter. So it would be great to either 1) have the 'pad' filter have in_w and in_h made available or 2) more generalizable, have a 'filter' that returns the dimension values of the video so it can be fed into an expression for evaluation and use in other filters in the filtergraph. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/61> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
