Hello Doom9. This is my first post after 5 days of patiently waiting - finally it's my turn in the line. :-) I am the lucky owner of one of the new Samsung Galaxy S II which records H.264 video and AAC audio in both 1080p and 720p. Furthermore it has built-in DLNA sharing support, so I can play the content on other DLNA-enabled devices such as the PlayStation3 - or can I? When I start the Allshare DLNA-server on my phone, I can access it from my PS3 and while my JPEG-shots display just fine, I am having problems with my video. The PlayStation3 simply refuses to play the file and reports it as unsupported - despite the fact that PS3 supports both H264 and AAC out of the box. With my limited technical insight into the MPEG-4 format I have isolated the problem and even identified a solution, although it's not ideal. When opening the recording in MediaInfo, I get the following information: Code: General Complete name : D:\Film\Galaxy II samples\road_original.mp4 Format : MPEG-4 Format profile : 3GPP Media Release 4 Codec ID : 3gp4 File size : 4.20 MiB Duration : 3s 508ms Overall bit rate : 10.0 Mbps Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : Baseline@L3.1 Format settings, CABAC : No Format settings, ReFrames : 1 frame Format settings, GOP : M=1, N=30 Muxing mode : Container profile=Unknown@1.1 Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 3s 508ms Bit rate mode : Variable Bit rate : 9 980 Kbps Width : 1 280 pixels Height : 720 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 30.217 fps Minimum frame rate : 21.739 fps Maximum frame rate : 43.478 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.358 Stream size : 4.17 MiB (99%) Language : English Audio ID : 2 Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : 40 Duration : 3s 456ms Bit rate mode : Variable Bit rate : 50.8 Kbps Nominal bit rate : 58.5 Kbps Maximum bit rate : 62.1 Kbps Channel(s) : 1 channel Channel positions : Front: C Sampling rate : 16.0 KHz Compression mode : Lossy Stream size : 21.4 KiB (0%) Language : English Notice the bold part. Apparently, the PlayStation3 doesn't like 3GP4. But if I open the file in QuickTime only to export it with direct stream copying, I arrive with this file: Code: General Complete name : D:\Film\Galaxy II samples\road_remuxed.mp4 Format : MPEG-4 Format profile : Base Media / Version 2 Codec ID : mp42 File size : 4.20 MiB Duration : 3s 541ms Overall bit rate : 9 943 Kbps Encoded date : UTC 2011-05-29 15:21:04 Tagged date : UTC 2011-05-29 15:21:04 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : Baseline@L3.1 Format settings, CABAC : No Format settings, ReFrames : 1 frame Format settings, GOP : M=1, N=30 Muxing mode : Container profile=Unknown@1.1 Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 3s 541ms Bit rate mode : Variable Bit rate : 9 886 Kbps Width : 1 280 pixels Height : 720 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 29.935 fps Minimum frame rate : 21.739 fps Maximum frame rate : 43.478 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.358 Stream size : 4.17 MiB (99%) Language : English Encoded date : UTC 2011-05-29 15:21:04 Tagged date : UTC 2011-05-29 15:21:04 Audio ID : 2 Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : 40 Duration : 3s 520ms Bit rate mode : Variable Bit rate : 48.0 Kbps Nominal bit rate : 58.5 Kbps Maximum bit rate : 62.1 Kbps Channel(s) : 1 channel Channel positions : Front: C Sampling rate : 16.0 KHz Compression mode : Lossy Stream size : 21.4 KiB (0%) Language : English Encoded date : UTC 2011-05-29 15:21:04 Tagged date : UTC 2011-05-29 15:21:04 The profile is now MP42, but the streams inside are the same. This new file is now playable by the PlayStation3. No transcoding, no tricks. For reference, I have uploaded both of above files for you to examine if you want: Original version: http://www.nielsbuus.dk/ting/skattek...d_original.mp4 Exported from QuickTime Pro: http://www.nielsbuus.dk/ting/skattek...ad_remuxed.mp4 Now - transfering every video recording I have made to my PC just to manually remux the video in QuickTime is a tedious task. Therefore I would like to ask you: Do you have any ideas for a smarter way to go around this? Please include pros and cons. I am not interested in anything that involves transcoding. I have searched the Android Market for an app that can batch remux video on the phone, but it seems that no such app exist. Any ideas?

And if Sony doesn't want to then try to contact Samsung and explain them the issue so they can maybe create a workaround mode for Sonys Playstation 3 (enable disable able via the Recording Gui). __________________ all my compares are riddles so please try to decipher them yourselves :) It is about Time Join the Revolution NOW before it is to Late ! http://forum.doom9.org/showthread.php?t=168004 Last edited by CruNcher; 29th May 2011 at 16:51.

I downloaded a hex editor and found the atom. Changed it from 3GP4 to MP42 and now it plays on the PS3 - amazing it was that simple. However, do you know if what I am doing is "anatomically safe"? I mean, is it legit to just change the identifier in a hex editor like that? Will it break compatibility with something else?

After the ftypXXXX there is 3gp43gp6

It sounds awfully resemblant of the previous identifier. Any idea what it does? 3GP4 3GP6. What is 3GP6?

Should I change them to MP42MP42?

Update: I've just done so and PlayStation3 still plays them.

Thanks! I didn't know ffmpeg could do that. :-)
Certainly beats running the stuff through QuickTime.

Because I fear it might just up at some clueless helpdesk worker that'll encourage me to check my HDMI-cable and make sure my network settings are dandy.
 29th May 2011, 17:18 #9  |  Link Lam3rD Registered User   Join Date: Oct 2009 Posts: 47 Another option is to ask the developers of Allshare DLNA-server to patch the file on-the-fly, it shouldn't be too hard to do and they are more likely to respond to such request __________________ "The significant problems we face cannot be solved at the same level of thinking we were at when we created them." -- Albert Einstein
