Applying Video Filters Using LibVLC with Android

阅读更多关于 Applying Video Filters Using LibVLC with Android

问题 Using LibVLC, I successfully added a VLC player to an Android app. However, I am not sure whether it is possible to apply video filters to a VLC player using LibVLC. Based on questions such as this, I suspect it might not be built-in for any filters, though I am not sure. Currently, I am attempting to pass in the video filter commands in the playMRL function, though I am simply receiving an unfiltered video. Below is the relevant code: String videoOptions[] = {"--video-filter=invert"}; this

【推荐阅读】微服务还能火多久？>>> 源码层次目录如下所示：其中： psi.c: psi section structure dvbpsi.c：抽象成DVB/PSI decoders，封装出接口，供应用层调用。 descriptor.c：各种描述符数据的抽象 demux.c：解复用器 descriptor/：各种描述符的解析 tables/：各种psi子表解析的具体实现每个解码器被划分成两个实体：即the PSI decoder和the specific decoder。之所以如此划分的原因是，每个psi表的section都有相同的格式。解码器结构如图1所示：图1：解码器结构 PSI解码器：主要任务就是获取应用层提供的ts流数据包（ STB则是根据底层的解码器芯片获取ts流），并将完整的psi section(段)发送给专用的解码器解析。对于不连续的ts流，PSI解码器也必须稳定可靠的工作，并将ts流交给专用的解码器处理。专用解码器 (specific decoder)：主要任务就是根据psi解码器提供的psi sections，重建完整的表(PSI/SI)并将他们返回给应用层处理( S TB通常是存入相应的databas e )，同时还要根据psi decoder的指示去检查ts的完整性(作CRC校验)。如果不完整，则返回错误。 PSI

流媒体技术学习笔记之（九）减少VLC 延迟的方法

　　之前写过一篇关于在 Linux 平台上编译 Android 平台上VLC播放器源代码的文章，vlc这款播放器非常优秀而且是开源的，它的核心是开源视频编解码库ffmpeg。而且这款播放器还支持RTSP协议，这个主要是用开源的live555来实现的，live555这个库以后还需要认真研习。一、PC端（Windows平台）VLC播放RTSP视频延迟问题解决　　前几天用PC平台上的VLC播放RTSP流媒体时延迟时间较长，存在1s左右的延迟，效果不是很好，后来查了资料，发现这个延迟时间是可以修改的。　　找到工具->首选项，然后参数设置左下角选择“全部”，左边选择 “输入编解码”->“网络缓存”选项，可以根据具体需要加以修改，具体见下图不过这个值不要太小，否则缓存太小，播放视频的过程中会很卡如果网络环境较好，300ms以内效果很好，实时性较好。二：PC端（Linux平台）VLC播放RTSP视频延迟问题解决　　这里我的测试平台是ubuntu，linux平台上的vlc可以以命令行的方式来运行，而命令行是可以带参数的，我们只需要在参数里面指定这个延迟时间就可以了，下面是具体的命令行形式，大家可以根据各自需要加以调整 vlc rtsp://192.168.1.1:8556/test.avi --newwork-caching=300

Is it possible to put track markers in between tracks in one large audio file so that an audio player will treat the file as a CD?

问题 Here's what I mean: I have several songs stored as individual mp3 files. I have amalgamated them into one large mp3 file. When I play the file with VLC or any other piece of audio player software, the entire file just plays from start to finish as expected. If I press the "next track" button, the right facing arrow next to a vertical line, the player software just starts the entire file from the beginning again. What I want to do is put some kind of marker in between the individual tracks so
