#1504(undetermined:new): Split an input video into multiple output video chunks
by FFmpeg 09 Jul '12

#1504: Split an input video into multiple output video chunks -------------------------------------+------------------------------------- Reporter: burek | Type: Status: new | enhancement Component: | Priority: wish undetermined | Version: Keywords: | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- So far, people can use -ss and -t to cut the video chunk out of the input video. But if they want to cut the video to multiple output chunks, they would have to start ffmpeg several times (probably in a batch script), changing -ss value (and maybe even -t too), which complicates things a little bit, since ffmpeg has to skip same starting interval of the input over and over again. Because of this, it might be usable to somehow change/add this feature that will allow users to specify cut points and get the multiple outputs, just like image2 does, numbering each output sequentially. An example usage might be something like this: {{{ ffmpeg -i input.avi -ss2 10,20,40,50,90,120,180 -vcodec copy output02%d.avi }}} This would instruct ffmpeg to produce several outputs, each of them generated based on cut points (defined in seconds). -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1504> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1514: support gray16 pixel format in tiff -------------------------------------+------------------------------------- Reporter: dericed | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: git- Keywords: tiff | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Summary of the bug: I would like to use a 16 bit gray pixel format in tiff. I see gray8 but if I want 16 bit I need to use an rgb64 pixel format (which is a bit larger than necessary). Here's a command that attempted to create a 16 bit gray tiff image (ffmpeg uses rgb64le).
