well, first of all sorry for the bad english, but this is the only forum i found where they know abaout the " file format error".
I bought an mp4 player in china with the rock chip.
The Mp4 came with an sample video but I ereased it becouse I saw it was an avi video and didn`t knew i had to convert the videos.
The sample video was from a war movie ( or something like that) and there were a few soldiers shooting to a building.
I dindt find the exact image of the mp4, but it is almos like this one:
mine is a bit smaller and it has the words "Mp4 player" writen and not "yepo".
I`ve tried with lots of converters like avconverterv1.0, avconverter2.0 avconvertersmart, superavconverter ( the trial version). But i keep geting the "file format" error.
The Mp4 came with the aviconverter2.0beta but when i tried opening the installer i get an" error launching instaler" error.
I dont know what else to do, I have converter like 200 videos with 200 diferent converters and nothing works. I also revised the "sample video download " seccion in this site, but i cant find the same video.
I hope somone can help me.
thx and sorry again for the bad english but this forum is my last hope xD.
