I just recently downloaded a "tv show" in .mp4 format, which contained a self-extracting/executing virus. When I played it (with VLC), it crapped out, and my AV presented an alert. Fortunately, my AV intervened and killed the "nasty", but only after it self extracted (and tried to execute).



After inserting a video to my articulate storyline file (.mp4 format), the video stops playing properly. Both when previewing the video, the entire file, and after publishing, the video runs fine for a minute or so, then the image freezes while the audio keeps running.

Has there been any updates on this issue? I am working in SL2 (current update) and my videos stop before they reach the end of their timeline (not the slide timeline). I am inserting .mp4s (stored and working locally), and they stop within a fraction of the actually end. I've tried Ashley's recommendation with the same result.

The above dir command will list your files and directories, along file sizes in bytes, and you should see all of them in the list (e.g. ffmpeg.exe, recover_mp4.exe, your good.mp4 and bad.mp4 files and so on). From there, you should follow up tutorial exactly as in the video.

Answer: Unfortunately, this file is, indeed, non-repairable because there is NOTHING to repair! If you open your bad.mp4 video file with a HEX Editor (low-level file utility that reads all files in their true binary formats), you will see that except maybe the header, entire file is filled with 0 bytes. This means that either there was a storage recovery error, copy-paste error, and that the actual file content is permanently lost on the storage medium. Your only hope, if the file was previously accidentally deleted, is to use another scan and recovery tool, that might recover it properly.

Is the file 1.mp4 small in size? Does it have any meaningful size in the first place? You may have to recover it properly with some other undelete or video recovery tool first, see my other replies and suggestions.

In some cases, tool will generate a lot of warnings, but the end recovered.h264 or recovered.mp4 files will be actually fixed / playable! You must test them in your media player (VLC or MPC HC are recommended). I have fixed several such videos, and they were fine, despite the warnings.

I recently get a video to edit but i need to convert from .MOV to .mp4. I use winff to convert the videos but when i try to convert i get the message: Unknown encoder 'libvo_aacenc.I use ffmpeg-full from aur and ffmpeg0.10, ffmpeg2.8, ffmpeg-compat-54 and ffmpeg-compat-54.

A container for video files packages the various parts of the file. This includes the visual images as well as the audio tracks and graphics. Containers are also referred to as a the format of that file. The common video containers are .mov .mp4.

Now, I know I can use iTunes to convert music. But it's quite a pain.. All I'm asking is: Is there anything built into OS X or UNIX for converting files? Right now I simply want to convert .mp4 to .mp3.. 041b061a72
