    v12 v13  
    44I have begin this ticket because of an plugin for '''VirtualDub''' ([http://virtualdub.org]), that uses the '''FFmpeg library''' to open a lot of formats, that before, was not possible before opening them, the '''FFmpeg Input Driver''' ([http://forums.virtualdub.org/index.php?act=ST&f=7&t=20025&hl=ffmpeg&s=67495223fa42f40b194fb75537b4b840]). Because of the problem of the framerate recognition, the plugin crashes in '''VirtualDub''', and is impossible the process these videos from my '''set-top-box'''. Now, with your reprodution of an identified problem, I can suspect that the recognition causes an too bigger output video, and it could be a motive for the problem of instability in '''VirtualDub''', the framerate is not correctly setted, being much bigger than the correct recognition of the correct standards previously explained. I suggest, if possible, that the developers put the framerate recognition in '''"29,970 fps"''', because, for example, the mentioned plugin will not use it correctly, using specific command of '''FFmpeg''' for set the framerate, just uses what is already configured in the '''FFmpeg library'''. About the '''DVD-Video''' conversion, previously I had an video '''".rmvb"''', that recognized the video in '''"12,000 fps"''' (instead of ''' "25, 000 fps"''') in the '''FFmpeg''' and '''ffplay'''. With '''SUPER''' ([http://www.erightsoft.com/SUPER.html]), at the time was possible to convert the video for '''DVD-Video''' with '''"25,000 fps"''', the correct recognition of the framerate. But, the video output had an problematic playback in common '''DVD Player''', I percepted an problem in the frame refreshing of the same. After the correction in both '''FFmpeg''' and '''ffplay''', and since the bug correction in this library, other programs, as '''FFmpeg Input Driver''', can convert with '''"25, 000 fps"''', and produces an better output result, including '''SUPER''' with '''FFmpeg'''.

    6 Please, about the framerate recognition, put the framerate of this video type in '''NTSC/CRT''' standards by default ('''"29,970 fps"'''), for '''FFmpeg''', '''ffplay''', and others, that this will be very helpfull for use with other programs based in '''FFmpeg''', for example, '''TsRemux''' ([http://forum.doom9.org/showthread.php?t=125447]) and '''VirtualDub''' with '''FFmpeg Input Driver''', because the result of the output will be very usable in the conversions or manipulations of many other programs using this library.
