[NULL @ 0x2421ea0] start time for stream 1 is not set in estimate_timings_from_pts
[mpegts @ 0x241d600] Could not find codec parameters for stream 1 (Audio: aac ([15][0][0][0] / 0x000F), 0 channels, fltp): unspecified sample rate

    Stream #0:1[0x102](und): Audio: aac ([15][0][0][0] / 0x000F), 0 channels, fltp
Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (output_10.mp4) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Incompatible pixel format 'yuv420p10le' for codec 'libx265', auto-selecting format 'yuv420p'
