Several places in the code currently call init_output_stream_wrapper(), which in turn calls init_output_stream(), which then calls either enc_open() or init_output_stream_streamcopy(), followed by of_stream_init(), which tells the muxer the stream is ready for muxing. All except one of these callers are in the encoding code, which will be moved to ffmpeg_enc.c. Keeping this structure would then necessitate ffmpeg_enc.c calling back into the common code in ffmpeg.c, which would then just call ffmpeg_mux, thus making the already convoluted call chain even more so. Simplify the situation by using separate paths for filter-fed output streams (audio and video encoders) and others (subtitles, streamcopy, data, attachments).
