Repairing 3gp video

[c0mrade2]

Hi!
I recently shot a video with my Galaxy Nexus and it somehow ended up to be corrupted :/
I browsed the internet thorougly and I find out a partial solution by repairing it with grem gb video repair tool. Now the video can't be played by my mac (only with Kigo Video Converter preview player lol), but almost completely by my phone and my tablet in SW mode (asus tf700).
So I looked over the net again and started to mess around with mp4box and ffmpeg. I tried to demux and remux it but uselessy... So I pulled every single frame from the video using ffmpeg tool, then remerged them into a mp4 video and added the audio with mp4box.
Here's the command I used, or something similar :P:
for splitting:

ffmpeg -i myfile.mp4 -qscale 1 -vf "hflip,vflip" -f image2 image-%07d.png

for merging:

ffmpeg -f image2 -i image-%07d.png -r 15 -b "something" -qscale 1 -vcodec h264 myvideo.mp4

I chose png in order to keep as much quality as possible (at least I hope )
Is there a better way to accomplish this?

Hi c0mrade2,

Seems you dedicated lot of effort to save your corrupted video. A part of used solution from "video repair tool" you could simply test to repair your damaged clip using MP4repair.org to see if results are improved. Quality using this would be preserved instead using ffmpeg remux.

Sure, cause my life is entirely dedicated to freely spam and promote software I didn't even buy... Next time I'll refer to it with vague metaphores and metonymies

By the way, thanks FireRouteR for your advice, I'll check it out.
