HTC Desire (Bravo) as a driving recorder

After many tests, I can recommend the only one camera application that records well in 640x480 resolution.

DailyRoads Voyager

or

DailyRoads Voyager Pro

Thanks to this Bravo can be used as a driving recorder, if you do not mind the lack of sound. Turning off the sound recording improves the video recording parameters.

I managed to record a few movies with sound that is fully synchronized with the picture (Syncho A-V).

Unfortunately, most movies do not have sound sync.

The author of the application who wrote to me that the application sends a request to the media server, but the server decides on the method of registration implementation depending on the possibilities.

The secret of the media server's operation is known only to good programmers ( = [MENTION=5091819]spezi77[/MENTION] ).

Therefore, it is very difficult for the user to set kernel parameters so that the system is efficient for video recording.

I attach two logs informing about the parameters that were used in the application during recording.
