FFMPEG: Incorrect codec parameters when trying to merge mp3 and webm files
11,172
[webm @ 0x7febd5009000] Only VP8,VP9 video and Vorbis,Opus(experimental, use -strict -2) audio and WebVTT subtitles are supported for WebM.
The webm output container only supports Vorbis audio and offers experimental support for Opus audio, so change libfdk_aac
to libvorbis
. The pan
audio filter can be used with any output audio format (as long as it can handle the number of channels, etc).

I received an "(incorrect codec parameters)" error after trying to
amerge
a .mp3 file and a .webm fileThe output format is .webm as well
Here's my ffmpeg command(s):
ffmpeg -y -i native.mp3 -i 530f79494f2610e5058b4c73.webm -filter_complex \ '[0:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=0.5[a1]; \ [1:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=0.5[a2]; \ [a1][a2]amerge,pan=stereo:c0<c0+c2:c1<c1+c3[out]' -map 1:v -map '[out]' -c:v copy \ -c:a libfdk_aac -shortest -f webm output.webm
And the logs:

PS:
libfdk_aac
I believe is needed forpan
streams. Hmmm, correct me if I'm wrong. -
emfolorncynosure about 10 yearsThanks for taking time again. However, I already solved this issue just before you posted this answer. I used vp8
libvpx
for vcodec andlibvorbis
for acodec. However, let me try to just change the acodec. Thanks a lot! :) Appreciate it.
