Я пытаюсь получить небольшой фрагмент клипа ProRes QT с несколькими аудиоканалами PCM (WAV), который я хочу скопировать в выходное видео; всякий раз, когда я пытаюсь скопировать аудиодорожки на выход с параметром карты, он использует аудиодорожку 1 для каждого выходного аудиопотока вместо отображения ch 1 -> ch 1, ch 2 -> ch 2 и т. д. В информации о мультимедиа есть значение «discreet-0» в поле положения канала, которое может вызывать проблемы. Например:
Audio #1
ID : 2
Format : PCM
Format settings, Endianness : Little
Format settings, Sign : Signed
Codec ID : in24
Duration : 2 min
Bit rate mode : Constant
Bit rate : 1 152 kb/s
Channel(s) : 1 channel
Channel positions : Discrete-0
Sampling rate : 48.0 kHz
Bit depth : 24 bits
Stream size : 17.9 MiB (1%)
Language : English
Encoded date : UTC 2016-06-19 23:57:56
Tagged date : UTC 2016-06-19 23:57:56
Моя команда выглядит так:
C:\ffmpeg-20160913\bin\ffmpeg -i "C:\TEST\input.mov" -map 0:0 -vcodec prores -profile:v 2 -ss 00:00:10 -t 00:00:05 -map 0:1 -acodec copy -map 0:2 -acodec copy -map 0:3 -acodec copy -map 0:4 -acodec copy -map 0:5 -acodec copy -map 0:6 -acodec copy -map 0:7 -acodec copy -map 0:8 -acodec copy -map 0:9 -acodec copy -map 0:10 -acodec copy -map 0:11 -acodec copy "test.prores.mov" -loglevel verbose
Мой вывод ffmpeg:
