问题 How to write bitmaps (RGB) as frames to H.264 with x264 in C\C++? Some Examples with source would be great! 回答1: Here is how: Look at the bitmap spec and work on loading a single bitmap Check out the x264.exe source code. That takes YUV uncompressed data as the source. Do some search on RGB->YUV conversion. Put it all together and modify x264.exe to load your bitmaps, convert them to YUV and pass them to the encoder 来源： https://stackoverflow.com/questions/1736301/how-to-write-bitmaps-as

How to tell if current frame is parent?

问题 I'm working in a framed environment, and trying to tell if the frame on which some javascript code executes is the top frame (the one that contains the rest). Up until now I was trying to check it with window.parent != null but it always returns false, like in this simple example. <html> <head> <script> alert(parent == null); </script> </head> <body> <h1>OH YEAH!</h1> </body> </html> Is there a way to do this? I doesn't have to be portable, right now I'm looking for the IE6 solution. 回答1: I

ffmpeg: How to add frames or black at the end of a video?

由 我的梦境 提交于 2019-12-10 11:07:40
问题 How to copy an arbitrary amount of duplicates of the last frame at the end of any video? Or alternatively, how to add black frames at the end of any video? Can this be done by scripting and ffmpeg? Of course any other tool is fine, as long as the action is scriptable. The difficulty is that all video formats, or at least as wide range of video formats as possible, should be supported. The script should take in any video formats without manually changing the script per video. 回答1: Take a look

问题 Is it possible to update the frames like in the interface builder but programmatically? Some of my objects get misplaced because of an animation (which I'll want to fix anyway, I guess..) but it brought to mind the aforementioned question Edit: I have done some googling as well as looking on stackoverflow and not found what I'm looking for. I want to update the frames of some buttons back to the constraints I set in the interface builder. Sorry if this is too simple of a question, but I'm
