Hi all, I have some issues with amerge channel layouts. Source file is a MXF with 2 mono stream. Output should be one stereo stream (L/R).
Source File: Input #0, mxf, from 'file.mxf': Duration: 00:04:25.96, start: 0.000000, bitrate: 51792 kb/s Stream #0:0: Video: mpeg2video (4:2:2), yuv422p(tv, unknown/bt709/bt709), 1920x1080 [SAR 1:1 DAR 16:9], 50000 kb/s, 25 fps, 25 tbr, 25 tbn Stream #0:1: Audio: pcm_s16le, 48000 Hz, 1 channels, s16, 768 kb/s Stream #0:2: Audio: pcm_s16le, 48000 Hz, 1 channels, s16, 768 kb/s I tried the following: ffmpeg -y -i file.mxf -filter:v yadif -b:v 8000k -minrate 8000k -maxrate 8000k -bufsize 4000k -vcodec libx264 -bf 2 -flags +cgop -pix_fmt yuv420p -f mp4 -filter_complex "[0:1][0:2]amerge=inputs=2,volume=14.4dB [aout]" -map [aout] -c:a libfdk_aac -b:a 384k -ac 2 -ar 48000 -cutoff 20k -movflags faststart -ss 00:00:00 file.mp4 But: Guessed Channel Layout for Input Stream #0.1 : mono Guessed Channel Layout for Input Stream #0.2 : mono ---- [Parsed_amerge_0 @ 0x2eae4d0] No channel layout for input 1 [Parsed_amerge_0 @ 0x2eae4d0] Input channel layouts overlap: output layout will be determined by the number of distinct input channels ---- So it isn't really a problem because the output audio stream is correct (stereo) "output layout will be determined by the number of distinct input channels". But how can I set a correct channel layout to avoid these warnings.
