MP4 Playing Issue on Toshiba Gigabeat MEGF40

(1/4) > >>

webtechy:
Hi All,

Hardware: Toshiba Gigabeat MEGF40
Rockbox Version: r16011-080107

New to this forum. Have successfully installed RockBox. It plays MP3 files fine. However, I have a "My Videos" directory in the root, and it can see the MP4 videos within that folder, but when I go to play them the screen goes black. The buttons are still lit, but I have to flick the battery on/off to restart the Gigabeat (i.e. power switch doesn't work). I know the standard Gigabeat doesn't play MP4 files, but I was under the understanding that it can with Gigabeat.

Any help much appreciated.

Regards,

Ben.

No, Rockbox cannot play MP4 videos. Nowhere on our site does it say it can. What it DOES say is that Rockbox can play MPEG 1 and 2 videos. This is covered on the wiki page for Mpegplayer, and should be in the manual as well.

MP4 videos show up because "MP4" doesn't actually mean anything but "data in an MP4 container." One common form of data in these containers is AAC music, and we can play that.

webtechy:
OK, are their any plans to enable MP4's to be played? Most video recorders (well, the ones I have) tend to record in MP4 format.

Alternatively, slightly out of scope, but does WMP11 allow for automatic conversion of MP4's to another support format on sync (another issues getting that to work though).

Cheers,

Ben.

Llorean:
As I said, quite clearly, "MP4" doesn't mean anything specific in terms of video format. MP4 can contain MPEG4-ASP, H.264/AVC, and probably other video formats too.

It will be necessary to convert your video to match the screen size anyway, so there's no real reason not to transcode in the process, since size conversion requires a form of transcoding anyway even if the format is preserved. Some methods of conversion known to work well are on the PluginMpegplayer wiki page, but are all user submitted.

And as I said in your other thread, questions for how to use WMP11 are out of scope of the forum. The best place to ask is somewhere offering support for that software, not somewhere offering support for completely different software.

webtechy:
Ok, thanks for that. I was simply wondering if users of this forum may have come across a solution to WMP11 sync issues. (Rockbox does indeed change the way my computer sees the device, as when I plug it in, it pops up in vista with a different set of options such as open folder, sync photos, etc., but still not able to sync music).

EDIT: (Merge of double posts)
NB I would however suggest that a message is displayed that the file type cannot be played and the crashing issue logged.

An enhancement would be to enable MP4 playback, and dynamically resizing the video to fit the screen.
