Hi to all I made a mov file with an ipad-mini with h264 codec. This is the result of frobe:

The code is quite simple: pCodec_qt=avcodec_find_decoder(AV_CODEC_ID_H264); pCodecCtx_qt = avcodec_alloc_context3(pCodec_qt); pFrame_qt=av_frame_alloc(); errCode = avcodec_open2(pCodecCtx_qt, pCodec_qt,NULL); av_init_packet(&packet_qt); packet_qt.size = <size read from table> packet_qt.data = <buffer with data read>; fFinished_qt = 1; errCode = avcodec_decode_video2(pCodecCtx_qt, pFrame_qt,&fFinished_qt,&packet_qt); Code starts in a strange fashion: ussually non annex B h264 format starts with (hex): 00 00 00 01 while the first chunk size starts with (hex): 00 02 f0 84 any suggestion or idea ?
