Problem importing GoPro Video File on iOS 7

[xepera]

Hello!

I recorded a video with Laptimer GP on the iPhone with my Gopro as satellite. Gopro splitted the file into 2 files, which i joined with avidemux (stream copy). So I tagged the file according the documentation, transferred it to the iPhone and Laptimer recognized the Gopro file.

Then i wanted to swad the iPhone video and Gopro video - Gopro as main video file and iPhone as PiP (or maybe delete). When I try to create the overlay Laptimer brings up an error: "Hauptfilm nicht nutzbar, 2 MultiCam Bild in Bild Videos verfügbar". ("Main Video not useable, 2 MultiCam Picture in Picture videos available.") I then go forward by clicking 'Overlay' then the message is followed by "Der Haupfilm ist aktuell nicht verfügbar oder es fehlen der Video oder Audio Track. Bitte Video Liste prüfen...." ("The Mainvideo is not available or the audio or video track is missing. Please check video list....") The joined videofile is playable in the iPhone Camera Roll...

What am I doing wrong? Thanks in advance!

Despite it plays in the video player, this seems to be an issue with the video format. In case you have ffprob installed, please let me know what "ffprob -i <video>" reports.

P.S. Seems the layout is not great for the 3.5 inch iPhone...

Thank you Harry for your quick response. Hereby the output of ffprobe.exe on the used videofile:

May be h264 be the problem?

[Harry]

No, H.264 and AAC is fine for the encoder side. Can you please add the -show_format option please?

ffprobe -show_format -i <video>

- Harry

[Harry]

It is probably a .mp4 container, the preferred format for iOS is .mov
You may try a conversion like this:

ffmpeg -i video.mp4 video.mov

Another ouput:

C:\ffmpeg\bin>ffprobe.exe -show_format -i C:\Users\xepera\Desktop\Soundvid\Test.
mp4

Okay thank you Harry, but it looks like it already is .mov now?

[Harry]

I thought the output is more specific on .mov vs .mp4... This is the output for a FullHD video generated on iOS:

At least the major brand field differs, although the long format is Quicktime / MOV in both outputs.

I have no idea what can be done, but you may try the .mov conversion posted above.

Okay thank you again Harry. Is there something like a standard procedure, some standard conversion i have to do to use the Gopro video files in the Laptimer App? How do other use their Gopro videofiles?

[Harry]

I have not seen many issues so far. It is probably best to use QuickTime player and use the export option to iPhone, iPad, iTV. Btw, you may try one of the segments recorded on the HERO instead of using the merged version.

Finally I got the solution: encoding to .MOV was the thing it needed to bring HLT back to work properly. As it seems the native Gopro video codec is not compatible with HLT, unless it is played correctly via iOS Camera Roll.

So - it works! (But I also had the 99% problem when HLT crashed. Rebooting the iPhone was the solution here.)

Thank you Harry for your great support.
