Its use for muxing is not documented, in practice it is incremented per each packet successfully passed to the muxer's write_packet(). Since there is a lot of indirection between ffmpeg submitting a packet to the muxer and it actually being written (e.g. the interleaving queue), using nb_frames to count packets sent to the muxer is incorrect. Use OutputStream.packets_written instead. --- fftools/ffmpeg_mux.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
