dtplayer_c's Introduction

dtplayer

dtplayer is an open-source project based on C , aimed to provide multimedia playing service base on ffmpeg(linux version2.0+).

At present, dtplayer have provided examples on stream-demuxer-decoder-render modules. User can easily understand how to add new element.

User can also remove ffmpeg dependence through modifing makefile (set DT_FFMPEG = no), Then you will get an aac player for now.

dtplayer_c's Issues

sub pts计算错误

ffmpeg解码出来的内置字幕pts,是时间单位(us), 需要换算成pts单位和av做同步

在解码器退出之后又render了一帧引起的问题

[feature] 优化直播启动速度

优化直播：如udp rtp sdp的启动速度

sdl full screen画面显示不正常

version: Linux
启动播放，切换到全屁，画面显示不正常。

cannot locate symbol "__register_atfork" referenced by "dtprobe_g.exe"...

升级版本到最新的as3.x后出的问题。

前面出现了 stderr atof的问题，更新了gcc的生产方式解决，但又出现此问题

Android硬解码pts全部是0

udp组播卡住后reset

直播如果数据错会出现播放器卡住的现象,需要添加reset机制

连续seek到结尾出现crash

gdb保存的栈信息如下:
