Muxing pcm audio in MOV using avcodec_encode_audio() was failing because avcodec_encode_audio() returns an incorrect packet size of 4 bytes. This can be reproduced by modifying the sample ffmpeg/doc/examples/muxing.c to encode PCM, see ML patch muxing-test.diff I git bisected and commit 89ddff92 is the one that broke this. In mov_write_header() if st->codec->frame_size <= 1 it sets it to 1. Then avcodec_encode_audio() sets frame->nb_samples = avctx->frame_size, and frame->nb_samples of 1 is used to compute a packet size of 4 bytes. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Closes ticket #999 NO_DSHOW_STRSAFE asks dshow.h header to not use secure string function replacements. Using secure replacements would break mingw.org compatibility as they don't declare/define those functions. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

According to unofficial documentation, the video rate is locked to the audio sample rate. This results in proper synchronization of audio and video timestamps from the demuxer. This only works if the first audio packet occurs before the first video packet or the audio sample rate is the default rate of 11111 Hz, both of which are true for all samples in our archive.

This avoids initializing a stream with dummy values or when the file does not contain audio. Also set duration for audio packets, using the sample rate as the time base.

By replacing memcpy with an unrolled loop using the alignment knowledge it has, some speedup can be obtained. Before (gcc 4.6.1): ~400 cycles After: ~370 cycles Overall, around 2% speed increase when decoding a 2400s mp3 to f32le. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

Otherwise, we end up with with log(0) or log(1). av_ceil_log2 simply assumes the argument is non-zero and returns wrong result when it is. (Not that there is a proper way of returning an undefined value.)
