[Libav-user] play mts(AVCHD) files

[王向伟 ＃]

Hi all,
I want to play MTS(AVCHD) file from my Sony Handy camera in my iOS app, but I only got audio, there is no video decoded. the got_picture parameter of function avcodec_decode_video2 always return 0. my app works OK with other media files like mp4, m3u8.generally the play logic in my app is almost same as ffplay application of ffmpeg.I played the same MTS file with ffplay in Windows, It plays well.I am new to ffmpeg, does anyone knows the reason that my app can't play MTS file.
I used the libraries downloaded fromhttps://github.com/kewlbear/FFmpeg-iOS-build-script
Here are some logs:
