| 3 | I am noticing an problem with .ts (BDAV - BluRay derivated library videos), in particular an video that I have captured with my set-top-box, it have wrong recognition by part of FFmpeg lib (this I have verified also with latest stable build ffmpeg-git-1eabd71-win32-static), and the problem persists. Could somebody of this Team of Developers analyse what causes the problem with framerate recognition? |

| 30 | , but unfortunately by FFmpeg, for example, with ffplay, recognizes that the video has 59,940 fps, as the double. Various program, that I know, possibly using FFmpeg, are having the same problem. If the video had been "59, 940 fps" or above, I'm not able to open and play in my CRT television (maximum supported according of my researches is 30.000 fs). An good program, that I have used for convert the same videos for DVD, is Freemake Video Converter, but this program need several updates (as.NET Framework 4.0 and xp SP3, and it is for new and adapted computers). The video crashes, and is impossible a good conversion, for example for DVD, by several programs. I hope that be possible to correct the mentioned problem, because the video is made with proprieatary codec libs (H.264, and Blu-Ray - BDAV) , and maybe is not fully supported by FFmpeg. |
