I've solved my issue. Shortly: I remuxed MP4 file to Annex B format with -bsf h264_mp4toannexb. Then, concatenating pieces of original (Annex B) file, and pieces filtered/transcoded by ffmpeg succeeds. As i have guess, Annex B format does not depend on on global headers aka extradata, and all the decoding information lies in the frames. Please correct me if i am not right.
