![]() ![]() For example:įfmpeg -i input.flv -itsoffset 00:00:03.0 -i input.flv -vcodec copy -acodec copy -map 1:0 -map 0:1 output_shift3s.flv This uses the libfaad AAC decoder, which is said to be a bit slower than the ffmpeg-builtin, but which decodes the AAC without complaining. Solution: Upgrade to latest ffmpeg and faad library version and add “ -acodec libfaad “ in front of the “-i” switch. In fact it could well be that they’ll handle it as an invalid input file. It doesn’t look like this will be handled by ffmpeg very soon. ![]() This is documented in various bugs (see ffmpeg issues #800, #871, #999, #1733…). The reason for the problem as I understood it is that the ffmpeg-builtin AAC codec cannot handle an audio stream stream with index “1.0”. Still the input video is playable in all standard players (VLC, in Windows…). ![]() The resulting video is either unplayable or has no sound. The message “Error while decoding stream #0.0” is repeated continuously. Stream #0.1(eng): Audio: libmp3lame, 22050 Hz, 2 channels, s16, 64 kb/sĬhannel element 1.0 is not allocated ![]()
