I have a Jensen Nav/Entertainment unit and am very happy with it, but I'm struggling to find a video encoding for the SD Card that doesn't take up huge amounts of space. Currently I am encoding videos to an AVI container with MPEG4 Codec and MPEG 1 Audio, 30 FPS. Results look and sound beautiful but the problem is it nearly doubles the size versus an MP4. The files are 480P or 720P so are not small to begin with. Here's the transcoding script I use:
mkdir AVI_Jensen2
avconv -i "${FILE}" -c:v mpeg4 -threads 4 -q:v 3 -tag:v xvid -c:a libmp3lame -q:a 4 AVI_Jensen2/"${FILE}"
(If you have a dual core, dial down the number of threads). This was the result of a LOT of experimentation and walks out to the garage. If no one is ahead of me in this adventure maybe it will help some of you out there.
Does anyone have any suggestions for a more compact transcoding? Even if you don't transcode, if you have a video on the SD card that works pretty well, and is still compact, maybe you could play it on a PC and get the properties for me.
Thanks!
