stream

问题 I am working on a file sharing site right now and I've run into a small problem. I am using the upload scrip uploadify which works perfectly but if the user wants i want the uploaded file to be encrypted. Now i have working code that does this as shown below but my server only has 1GB or memory and using stream_copy_to_stream seems to take up the size of the actually file in memory and my max upload size is 256 so i know for a fact that something bad is going to happen when the site goes live

问题 I have a MemoryStream with the contents of a Font File (.ttf) and I would like to be able to create a FontFamily WPF object from that stream WITHOUT writing the contents of the stream to disk. I know this is possible with a System.Drawing.FontFamily but I cannot find out how to do it with System.Windows.Media.FontFamily. Note: I will only have the stream, so I can't pack it as a resource in the application and because of disk permissions issues, will not be able to write the font file to disk

问题 I cant seem to find a decent example that shows how can I consume an AWS Kinesis stream via Python. Can someone please provide me with some examples I could look into? Best 回答1: While this question has already been answered, it might be a good idea for future readers to consider using the Kinesis Client Library (KCL) for Python instead of using boto directly. It simplifies consuming from the stream when you have multiple consumer instances, and/or changing shard configurations . https://aws

问题 I am looking for a memory stream implementation in Java. The implementation should be roughly modeled after the .NET memory stream implementation. Basically I would like to have a class MemoryStream which has to factory methods: class MemoryStream { MemoryInput createInput(); MemoryOutput createOutput(); } class MemoryInput extends InputStream { long position(); void seek(long pos); } class MemoryOutput extends OutputStream { long position(); void seek(long pos); } So once I have an instance

问题 I use NetworkStream with sockets in an SslStream socket server as follows: stream = new NetworkStream(socket, true); sslStream = new SslStream(stream, false); My question is, if when I call sslStream.Dispose() , will the SslStream dispose/close its inner stream and its socket too? Or do I need to explicitly close all three resources with sslStream.Close() , stream.Close() and socket.Close() ? 回答1: If possible, you should use C#'s using construct to dispose the stream 'automatically' after use

问题 I want to add audio to my ffmpeg cli bellow ffmpeg -framerate 25 -video_size 1920x1080 -f x11grab -i :0.0 -vf format=yuv420p http://localhost:8080/feed.ffm I tried -acodec libmp3lame, -c:a libmp3lame but it does not seam to work 回答1: You have to provide an audio input. Assuming ALSA: ffmpeg -framerate 25 -video_size 1920x1080 -f x11grab -i :0.0 -f alsa -sample_rate 48000 -channels 2 -i hw:0 -c:v libx264 -c:a aac -vf format=yuv420p http://localhost:8080/feed.ffm See FFmpeg ALSA input
