[Libav-user] movflags > faststart

[William Troup]

I'm trying to use the following code to set faststart:

Avutil.av_dict_set(&headerOptions, "movflags", "+faststart", 0);

This is passed through as follows:

int writeHeaderResult = Avformat.avformat_write_header(formatContext,
&headerOptions);

The file writes correctly, but its an invalid mp4 that will not play.

I'm totally confused and have been searching for days for an answer.

The DLLs i'm using are:

avcodec-56.dll
avdevice-56.dll
avfilter-5.dll
avformat-56.dll
avutil-54.dll
postproc-53.dll
swresample-1.dll
swscale-3.dll
