hello, i recovered some videos from a physical image of a microsd card obtained with ftk.the files have name and extension(200-300 mb each)
i can't play them they do not start…do you know any software that can help me?
thank you
Are you sure what the files contain on movies?
MP4/3GP etc
Most videos, when recorded on a camera are not recorded in sequence. Typically, the mdat is stored physically first, and the ftyp and moov later. If a recovery program tries data carving, one ends up with ftyp+moov from file 1 joined to mdat from file 2. The result is a file that may look correct, but is very wrong.
There are numerous variations in recording and the worst is GoPro where low and high resolution videos are multiplexed together. A Panasonic had all ftyps at the start of the memory, and all mdats at the end. A Sanyo had the moov atom fragmented, and out of sequence, interleaved with the mdat! In all cases, when a file is deleted, or chip reformatted, the FAT is lost, so all allocation data is also lost.
I have added many such cameras to my
AVI videos are often recorded out of sequence. AVCHD (.MTS) are fragmented, with meta data files inserted in the data stream area. .MXF files appear to be in three, out of sequence fragments.
i used a video to jpeg software and i extracted frames from many of not playable videos, so now i'm ure they are video files…they were taken by a motion sensor camera,the cheap models you can buy online,no brand.but many of them are still empty
And ffplay doesnt play anything?
didn,t know about it.i'm going to try it
thank you for the suggestion
Re-read what mscotgrove wrote.
S/he is not writing that it is not video, just that it is most likely carved/extracted/recovered incorrectly.
