The simplest example of memory read/write based on FFmpeg: Memory Transcoder and ffmpeg read/writeThe previous article recorded a memory Player Based on FFmpeg, which can be used to read and play data in the memory. This article records a memory Transcoder Based on FFmpeg. The Transcoder can use FFmpeg to read data in the memory. After transcoding to H.264, the data is output to the memory.For details about how to read data from the memory and output data to the memory, refer: Ffmpeg reads data

Install the video conversion software Handbrake 0.10.5 in Ubuntu 16.04 Handbrake allows you to directly convert a DVD into an AVI/MPEG4 format without special skills, as well as MP4 and OGM output, AAC, and Vorbis encoding. HandBrake can convert an encrypted (encrypted) DVD to work in multi-tasking mode. It also allows you to select the language, sound and image quality, and the converted image size. Handbrake 0.10.5 was released earlier this year. It

③ canceling device files. Now, the driver module has been compiled. After compilation and loading, we can read data to the camera like an ordinary file. 2.2 MPEG4-based Data Compression Algorithm 2.2.1 MPEG-4 [7] Compression of standard digital video stream data volume is huge, taking a qvga image with 20 frames per second as an example, the data volume per second is 2.92 MB. Assume that the system has ten sensors, it is quite difficult to realize th

In the previous article, I talked about how to use JNI for h264 encoding, but the efficiency is not very practical. After several days of hard work, refer to the real-time coding problem of Android with reference to http://www.javaeye.com/problems/27244.

processing capabilities to achieve faster than real-time decoding and transcoding speed. You can convert video to H.264 and MPEG-2 formats at speeds of up to 19 times times the CPU usage. You can convert full 1080p files to H.264 and MPEG-2 formats, up to 1.8 times times faster than real time. Analysis of Avivo Video acceleration Technology Video codec and video capture is a pair of inseparable "twin brother", to capture a signal entered in analog mode, it must be encoded and stored in a suit

the successful FLV video format file, the use of video Converter to convert MP4 format, here is recommended for the Fox Nest Video Converter , the function is more comprehensive and fast. 　　software name: Beaver Nest Universal Video Converter 5.1.0.0 Free Edition Open the Beaver Nest Almighty Video Converter, add video, set output format, as shown in the following figure: ① Add video to add the FLV video that has just been converted; ② set output format, in the Pull box to select: Commonly

Many people want to put subtitles and AVI and two as one, so you can avoid the subtitle software (subtitle space is also saved) and can be in support of MPEG4 (XviD and DivX) DVD machine to play, subtitle files in the video when the plug-in and embedded type. 1. Plug-type: The video and the same file name of the subtitle software in the same folder, and then use the Storm Audio video playback, will display subtitles. 2. Inline type: Turning the subt

Step 2:1.setAudioSource (MediaRecorder.AudioSource.VOICE_RECOGNITION), voice_recognition compared to the mic will be based on the needs of speech recognition to do some tuning, of course, This needs to be supported by the system.2.setVideoSource is naturally videosource.camera, except that these two settings must be set before the encoder is set, which need not be explained. Step 3:The

I said in the last article how to use JNI for H264 encoding, but it's not very practical because of the efficiency problem. After several days of tossing, and referring to the general implementation of the http://www.javaeye.com/problems/27244 Android real-time coding problem, but only thinking, has not entered the stage of code implementation. More important 2 classes of Mediarecorder Parcelfiledescriptor Mediarecorder is a class that Android provides for collecting code, and Parcelfiledescri

This format is mainly used in the production of DVD/SVCD (compression), but also in some HDTV (high-definition TV broadcast) and some high-demand video editing, processing, there is a considerable application. The file extensions for this video format include. mpg,. MPE,. mpeg,. M2V, and. vob files on DVD discs. MPEG-4: Developed in 1998, MPEG-4 is specifically designed to broadcast high-quality video streaming media, which uses a narrow band to compress and transmit data wit
