Is there some loss of honour in releasing too many firmwares in one year? Microsoft release software patches every few weeks. 15 pages of threads for this ONE issue and no fix? Release a **bleep** patch. I have wasted an entire Sunday when I should have been spending time with my family. I am tired of trying to do WD’s work for them, like Joey Smyth said, this has been fixed in the new player (which I have too). I only have one file that won’t play and I poured over it for hours, and when I found that FFMpeg fixed it by simply remuxing it, I thought that the atom position/order was it. I have spent all day trying to find a fix for this, to no avail. Not that it matters, I have learned an important lesson today. You must have them the wrong way round, all my mp4s play and have the structure:Ītom moov 24 of size: 93274, ends 93298Ītom mdat 93298 of size: 24569738, ends 24663036Ītom free 24663036 of size: 59, ends 24663095 I know we shouldn’t have to, but it appears the best way to obtain a resolution in this instance. If so, it would be a step in helping WD to fix this player.
My theory is that when moov is first, this will not play, and when mdat is first that it will play. Guys, it would be great if you could download and run this app and post your problem files atom structure to confirm that this is the issue (I believe that it is). Note that it will also have an atom (or possibly atoms) named free, these will be in an arbitrary position and aren’t important in this instance.Ī playable file should have the structure (once again with free atoms in a random position: It should (if my theory is correct) show the atom structure as:
Mediainfo moov atom mp4#
Install it, and point it at your problem MP4 file, them click the file name at the top left of the window. The app is safe it is the first website Google points to when searching for “MP4 atom viewer”. To help me and WD determine the problem, it would be great if you guys could test your problem files by downloading this tiny 300kb app from here: What is atom structure in an MP4? Adobe has a great explaination here: I’m doing some digging into this issue and it appears it has something to do with the atom structure of the video, namely the position of _ moov _ before _ mdat _ seems to be the culprit.įFMpeg by default saves mdat before moov, which is why the WDTV will play a problem file after I remux it with FFMpeg.
