[Libav-user] Using av_write_frame AFTER av_write_trailer

I'm using avio_alloc_context with my own "write_buffer_proc" to override
file procedures.
I am trying to continue writing the stream with av_write_frame AFTER
av_write_trailer was called.
But av_write_trailer has some strange side effects.
The result is AV in module 'avformat-58.dll'. Read of address
I think that FormatContext becomes invalid after av_write_trailer?

Can I try to save FormatContext somewhere before calling av_write_trailer ?

With best regards,
Alex K
