Have been eyeing one of these for a while: http://www.autosportlabs.com/ They provide bluetooth connectivity for mobile devices, but I can see it being pretty tricky since it's the same device providing GPS, accelerometer, gyro and all engine telemetry. However, the specs are pretty amazing...50Hz G...

No go with that conversion tool either. The source really doesn't seem to matter. I sucked it up and bought race renderer so I could get some overlays done in the meantime and of course that works just fine. The need to sync datalogs to video is a pain of course and the lack of corner names, corner ...

I found an editor that would work, MPEG Streamclip v1.2. It probably works because it's old. The latest copyright date is 2008. So I cut out a lap from the HQ video and saved it without changing format, used iBrowse to put it in the documents folder on a new (yes, you can actually win things on tho...

Wait, then why did you send a link to a PLAYER for your reference of a claim that stock android can't handle xvid? If it can play it, it can decode it. Encoding is handled within Harry's. You can actually throw a huge variety of videos into Harry's and it will encode them. Just haven't found one yet...

Also, I don't know how videoredo determines it's codecs but mpeg4 part 2 and xvid are not the same. xvid did implement mpeg4 part 2 but they're not actually interchangeable terms. Also, I dropped that video onto a fresh tablet with nothing on it but the stock player and it handles it just fine.

My point is that the mpeg codec you used was not H.264, it was Xvid. The problem is that very likely neither the original GoPro video nor your re-encoded video are compatible with the Android codecs. Likely the resolution and bit rate of the original video was too high. When you re-encoded it with ...

VideoReDo says the clips are MPEG4 Part 2, which it doesn't support. That's the old divX/Xvid standard, according to ffmpeg.org, that was replaced by H.264. I'm betting that's the problem with that video anyway. Somehow the GoPro H.264 video was converted to the old standard. The fact that it won't...

OK, i collected the trace and sent you an email with it. I also put it up on the drive here: https://drive.google.com/file/d/0BxWx9e ... sp=sharing

I took the same video but generated regular mpeg4 with qscale set to 3 (higher quality) and reran overlay for one lap. This time I'm also including the session datalog from Harry's in case you (Harry) can try to actually run the overlay on your device. You may be able to confirm if the original reco...

But I didn't see the GoPro originals and the problems I see in the raw video do not look to be irrelevant to the overlay. The playback is jerky using about every player I have. Any overlay is going to make things worse. Why would any overlay make things worse? Video is video regardless of how fast ...
