They are both based upon the MPEG4 video codec standard, and produce MPEG4-compliant video. MPEG4 is the name for both a video codec standard, AND a file format standard used for storing both video and audio (using the MPEG4 video codec standard and AAC audio).ĭivx and Xvid are names of MPEG4 video codecs. Strangely, these both work ("Extract Visual Track ID _ to an AVI file" command line):Ĭ:\>"C:\Program Files\YAMB\MP4Box.exe" -single 2 "G:\pub\yamb_tst.The relationship between Divx, Xvid, and MPEG4 is often confusing. Notice that they are the same mp4box command. G:\pub>"C:\Program Files\YAMB\MP4Box.exe" -single 2 "G:\pub\yamb_tst.mp4"Ĭ:\>"C:\Program Files\YAMB\MP4Box.exe" -single 2 "G:\pub\yamb_tst.mp4" This fails ("Extract track ID _" command line): Drive C: is local and drive G: is shared. I think this is due to the following behavior of mp4box so it is not a bug in Yamb. This is strange because the "Extract Visual Track ID _ to an AVI file" works on either a shared/mapped drive or a local drive. If the input file is on a shared/mapped drive on my server, the "Extract track ID _" function of Yamb does not work. Here's a revision to my previous reported behavior, that I now believe is unrelated to the source video: I'll also try a test without bframes and also some DVD source. Bond, would you like to file a (much more expert) bug report I don't know if the project is still under development but I'll file a bug report anyway as it should be making correct. ![]() OpenShiiva is clearly designed for DVD source, but I assume it would have the same problems with DVD source too. Thanks everyone! The source was originally 1080i ATSC.īond, I encoded it with OpenShiiva as I'm checking out some Mac encoding aps. Then, with mkvextract you should be able to extract each tracks. So, does anyone can confirm that mp4box is not compatible with hd stuff as input ? I don't have much hd files here apart the Calinb sample.įor the moment, if you want to extract video and audio tracks, you can try to mux your file into a matroska file (via mmg). Otherwise, I suspect the HD resolution.I tried to remux your sample directly in mp4 and mp4box doesn't seem to like the video track (I've a bad parameter error as return). We can see that video
