Ffmpeg is a very fast video and audio converter that can also grab from a live. For example, to select the stream with index 2 from input file a.mov (specified. Exit after ffmpeg has been running for duration seconds. Workaround various bugs in microsoft broken decoders. Apple HTTP Live Streaming demuxer. When I try to convert.mov to.flv and I drop the source video into, I cannot view either the source or the final preview. When I convert I get a.flv with no duration and it plays nothing. The.mov is viewable in with no problems. In another thread with similar but not exact issues it was suggested to install. I get a successful download of flvtool2. When I follow the instructions for the install on ffmpegX's site and I drop the downloaded flvtool2 folder into the Terminal app with a cd command I get a 'no such file or directory' error and yet the folder is clearly there with contents. What am I doing wrong with the flvtool2 install and/or how do I get my.mov file converted to.flv successfully?

What am I doing wrong with the flvtool2 install? The should be a space character after the cd command, then drop the folder. Android emulator use mac camera software. Flvtool2 adds metadata (duration, seek points, etc) to FLV files, after a successful conversion. The metadata will help playback (via the Flash browser plugin) e.g. By adding 'time remaining', and visual scrubbing though the timeline. I do not have Quicktime Pro for the invert mapping and therefore I am still getting the 0.0 length issue. I doubt if I will need to do this enough to justify buying Quicktime Pro. Instead of making FLV files, try creating MP4 files (H.264/AAC). They are just as suitable for Flash web video, while also viewable when users prefer HMTL5 video over Flash (think iOS). You may also want to look into qt-faststart, which should re-arrange the MP4, to have its metadata at the beginning of the file, so that playback can begin before the file is fully downloaded. In ffmpegX there are the options for H.264 (mencoder), H.264 (ffmpeg) and H.264 (X264). Is one preferable over the the others? There are a couple of differences, which could make one option more suitable than the others. Mencoder H.264, in this implementation, always writes 5.1, which is no problem for most software players, but that (needlessly high) level could lock out some hardware players. These mencoder H.264 files won't transfer to an iPhone 5 because of playback compatibility, according to iTunes. Ffmpeg H.264 is only used by the PSP preset, not by other presets. Not sure why. X264 H.264 allows you to set the AVC level, which is why I prefer it. The AVC level sets a maximum on various properties, most notably the resolution and framerate. For a 480p video, level 3 is enough, and level 3 gives plenty of compatibility. Stream #0.0(eng), 1.00 fps(r): Video: smp3 / 0x33706D73, 640x480 Stream #0.1(eng), 0.07 fps(r): Video: qtrle, 640x480 Stream #0.2(eng), 0.07 fps(r): Video: qtrle, 640x480 It seems you have three video streams in your source file. The 2nd and 3rd use the Apple Animation codec (qtrle). These could be some overlay (e.g. Text or logo) or a mask (changing the shape of the 640x480 video). I don't recognize the first stream (smp3), but perhaps QuickTime Player can tell you what kind of video that is (menu > Window > Show Movie Inspector ⌘I). It could be a legacy codec or a codec from some vendor. I don't think ffmpeg can convert it while merging these streams. But QuickTime probably can. Try exporting from QuickTime Player.
