The UnUsual Suspect Posted May 16, 2011 Share Posted May 16, 2011 Without a sample of the file that won't play, it would be difficult for the developers to figure out why. Digital video is usually encoded with multiple layers, then all put within a "container". Your only providing the name of the container with no information as to what it contains. A sample would be best, or you can get a free tool like Gspot that will analyze the video. Link to comment Share on other sites More sharing options...

The UnUsual Suspect Posted May 16, 2011 Share Posted May 16, 2011 Here is some information on .3gp container (source wikipidia) The 3GP file format stores video streams as MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264), and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC v1 or Enhanced aacPlus (HE-AAC v2). 3GPP allowed use of AMR and H.263 codecs in the ISO base media file format (MPEG-4 Part 12), because 3GPP specified the usage of the Sample Entry and template fields in the ISO base media file format as well as defining new boxes to which codecs refer. These extensions were registered by the registration authority for code-points in ISO base media file format ("MP4 Family" files).[11] [12] For the storage of MPEG-4 media specific information in 3GP files, the 3GP specification refers to MP4 and the AVC file format, which are also based on the ISO base media file format. The MP4 and the AVC file format specifications described usage of MPEG-4 content in the ISO base media file format Basically, there could be many different kinds of video within it.

The UnUsual Suspect Posted May 16, 2011 Share Posted May 16, 2011 It seems Gspot cannot tell what codec it's using. Perhaps it's something new, or it may even contain DRM (digital rights management) to prevent it from playing. If your making these videos yourself, then please provide a very small one so that it can be analyzed. Link to comment Share on other sites More sharing options...
greywizard Posted May 16, 2011 Share Posted May 16, 2011 AFAIK Gspot doesn't recognize all flavors of MPEG4. There are other tools like MediaInfo which handle that format way better. Link to comment Share on other sites More sharing options...
The UnUsual Suspect Posted May 16, 2011 Share Posted May 16, 2011 Yes, it seems gspot hasn't been updated in a few years. Your suggestion is probably a better one. Link to comment Share on other sites More sharing options...
