[boyXiong]

I found that I use iOS hard coded H264 files generated can play in the VLC, but with the landlord of this but can not be resolved, suggesting that the error is decode failed status=-8969 IOS8VT:

Can you tell me why

-8969 is kVTVideoDecoderBadDataErr, which means something wrong in your video data.
notes that the IOS8VT needs mp4 style NALU header, the NALU starts with four bytes uint32 in big endian, not starts with "00 00 00 01".
