When uploading images from Android, you can also compress,But when uploading the video, there is no good compression method.Then I thought of two ways to solve it.1 is the traditional HTTP post upload, the content is file flow, but do not know how much endurance, the advantage is that this method has matured, file flow, the transfer of Base64 processing, memory overflow situation is much less.2 is the

Use Videoview in the layout file to control it with Mediacontroller. 3, using MediaPlayer class and Surfaceview to achieve, this way is very flexible. 1, call its own player: Uri uri = Uri.parse (Environment.getexternalstoraged

the ways to get screenshots and thumbnails of video files, and you may also need to save bitmap as a file: /** * Bitmap Save As File * * * @param bitmap input bitmap * @param name output file ' s name * @return String o Utput file ' s path /public static String Bitmap2file (Bitmap Bitmap, String name) { file F = new file (environm Ent.getexternalstoragedirectory () + name + ". jpg"); if (f.exists ()) F.delete (); FileOutputStream fout = null;

automatically focus during recording. The default focus is the origin of the Camera coordinate system. The Camera coordinate system will be discussed later. It is worth mentioning that not all mobile phones support continuous-video. If your project needs to enable continuous focus for those phones that do not support the continuous focus mode, there are usually the following ways: Image Recognition uses various XX algorithms to determine whether th

Based on the decoding method in FFmpeg open source code, this paper adopts multi-thread receiving data packet, multilevel buffering data, receiving and decoding parallel double-threading operation, and so on, which can alleviate the data jam, decoding error, video screen slowness, delay and so on due to the large amount of data transmitted and fast speed. So that the transmission speed of the
