#3720: Support decoding of Xunlei XV file -------------------------------------+------------------------------------- Reporter: ElDimentio | Type: Status: new | enhancement Component: | Priority: wish undetermined | Version: git- Keywords: xv | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Xunlei is a major Chinese corporation with a monopoly on video downloading in China; they allow to download and play all sorts of Chinese TV shows for free but they're all in XV format, which is only supported by a video player Xunlei made. The video is H.264 video. FFMPEG cannot play this. When I try "ffmpeg -i 1.xv" I get the following: http://i.imgur.com/PrRNzvs.png Here is a link to 1.xv: https://www.dropbox.com/s/0rlzjm9b1apg0j5/1.xv 1.xv is 180MB, and it's supposed to be a video of about 45 minutes.

#4638(undetermined:new): Multithreaded FLAC encoding

#4638: Multithreaded FLAC encoding -------------------------------------+------------------------------------- Reporter: xtemp09 | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: Keywords: | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- I found that FLAC encoding utilizes only 100% of CPU, instead, e.g. 1200% (I have 12-core computer). It takes so long when encoding large files at maximum compression level. Could you add multithreading to FLAC encoding? Maybe, openCL would be help common users too. flaCCL, FlaCuda are multithreaded and have better compression than that one of ffmpeg. Could you include them into ffmpeg? I hope this request won't hang here 3-2 years like many others. :'( -- Ticket URL: <https://trac.ffmpeg.org/ticket/4638> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
