这个在 Linux 中堪称最好用电影播放器的 MPlayer 于8日推出了 1.0rc2 版。该版本主要改进了 FFmpeg，为其添加了一些新的视频和音频编/解码器。另外，MPlayer 还提供了对 Real RTSP 验证的支持，并能够播放更多的 HDTV 流媒体。
以下是 MPlayer 1.0rc2 的详细更新情况，供大家参考：
DOCS:
– console messages and XML documentation converted to UTF-8
– Russian documentation translation finished
– Russian man page translation finished
– Chinese man page translation finished
– Chinese documentation translation started
– Documented get/set/step properties in DOCS/tech/slave.txt
Decoders:
– Intel Music Coder audio decoding via lavc
– Monkey Audio audio decoding via lavc
– Fraps v2/v4 video decoding via lavc
– Video game codecs: 4XM audio, Electronic Arts ADPCM audio, Delphine CIN audio and video, Interplay DPCM audio, Sierra VMD video, Tiertex SEQ video, Westwood IMA ADPCM audio, XAN wc3 video, Id CIN video, Interplay video, XAN ADPCM audio, Westwood SND1 audio, Feeble Files DXA video, THP audio and video, Renderware TeXture Dictionary video, Bethesda Software VID video via lavc
– video game codecs: XAN wc4 video via binary DLL
– libmpeg2 updated to 0.4.1
– fixed resolution switching with libmpeg2
– handle resolution switching for Real codecs
– FFmpeg video decoder can now handle aspect ratio changes
– AMR now handled via libamr wrapper (http://www.penguin.cz/~utx/amr)
– SIMD optimizations for mp3lib under AMD64
Demuxers:
– Implemented switch_video and switch_program consistently with switch_audio (default keys are “_” and TAB, respectively). For the time being program switching is only available in TS streams handled by demux_ts.c (not libavformat), while video switching is also handled by demux_lavf.c and demux_avi.c.
– audio and video switching for the AVI demuxer (video switching untested)

– support for EVO demuxing
– support -noidx with libavformat demuxer
– support for channel navigation with PVR input
– text subtitles should now work with libavformat demuxer
– cleaned up TiVo demuxer
Streaming:
– authentication for Real RTSP streams
– near-precise seeking in dvd:// and dvdnav:// (dvdnav:// requires libdvdnav from mphq)
– speed selection when playing dvd:// streams, to make drive quieter
– support SVQ3 and H.264 in X-QT over RTSP, now RTSP Apple keynotes work (live555)
– SMIL playlist over Real RTSP
– support H.263-2000 over RTSP (live555)
– fix AAC-LATM over RTSP (live555)
– support AMR over RTSP (live555)

– fine tuning for tv://
– driver autodetection for tv://
– libnemesi RTSP/RTP support
– EOF detection for RTSP (live555)

– Atrac 3 audio decoder
– MPEG-1/2 speedups
– RoQ muxer, video and audio encoder
– QTRLE encoder
– AC-3 decoder
– Matroska muxer
– Monkey’s Audio demuxer and decoder
– Flac encoder and decoder speedups
– AMV demuxer and audio/video decoder
libmpeg2:
– iWMMXt-accelerated DCT and motion compensation for ARM processors
Filters:
– obsolete fame filter removed
– vf_geq speed-ups
– vf_yadif green frame fixed
– fix af_pan when switching audio streams
– add audio left/right balance feature to af_pan
MEncoder:
– write to output streams (currently only file:// and smb://)
– support -ffourcc with -of lavf
– removed B-frame warning message
– fixed bugs that would corrupt headers in the video stream when using telecining and not patch the TFF flag correctly
Ports:
– Complete Intel Mac support
– Hitachi SuperH (SH3) support
– Blackfin optimizations
Drivers:
– ALSA audio output now sets the non-audio bit for AC3 passthrough even if the user-specified default device name tries to clear it
– fixed internal VIDIX in Solaris/x86, also auto-enabled
– rework of internal VIDIX, now a fully static library with builtin drivers
– updated VIDIX ATI drivers
– Sun XVR-100 video output driver
Others:
