Is it possible to create a REMUX with exact frame count output.

[apiszcz]

In the remuxing documentation example packets are used and skipped if no dts is available in the packet. Is it possible to create an output with the same number of frames as the input using the decode to frame method?

This produces a different size output file much smaller (50%) from the input.

fps = src_stream.average_rate
codec_name = src_stream.codec_context.name
out_stream = ovideo_container.add_stream(codec_name, rate=fps)
out_stream.width = src_stream.codec_context.width  # Set frame width to be the same as the width of the input stream
out_stream.height = src_stream.codec_context.height  # Set frame height to be the same as the height of the input
out_stream.pix_fmt = src_stream.codec_context.pix_fmt

for frame container.decode(video=0):
   .. other processing then
   output_encoded = out_stream.encode(out_frame)
   ovideo_container.mux(output_encoded)

Trying the following to set the parameters produces the following error.

out_stream = ovideo_container.add_stream(template=src_stream)

    out_packet = out_stream.encode(out_frame)

Using the first approach above with another file the results are better the output is larger (file size) with a longer play time.
