[FFmpeg-devel] [PATCH] avformat/concat: finalize the AVBprint buffer immediately

I confirm your memory. The documentation states:

 * The string buffer grows as necessary and is always 0-terminated.

And I checked: there is no obvious bug in the avio_read_to_bprint() code
path, it ends with av_bprint_grow() adding the final 0.
