By the way, you have three outputs, two of them named output2.wav! And where's your MP3 output? You should habe noticed this from your output stream mapping. Assuming you mean to have three: > The problem is that audio mixing is applyed only to first amr file. > How can I apply the audio mixing to all output file. You should change to something like this: $ ffmpeg -i 1.amr -i 2.amr -filter_complex "amix=inputs=2:duration=longest:dropout_transition=2,asplit=3[audio1][audio2][audio3]" -map "[audio1]" -c:a amr_nb -ac 1 -ar 8000 -b:a 12.2k -y output1.amr -map "[audio2]" -c:a pcm_alaw -ac 1 -ar 16000 -y output2.wav -map "[audio3]" -c:a libmp3lame -ac 1 -ar 16000 -y output3.mp3 Note splitting the filter output into three using asplit=3[audio1][audio2][audio3] and mapping each of those filter chain outputs to an output encoder using -map "[audioX]" This gives me: Stream mapping: Stream #0:0 (pcm_s16le) -> amix:input0 Stream #1:0 (pcm_s16le) -> amix:input1 asplit:output0 -> Stream #0:0 (libopencore_amrnb) asplit:output1 -> Stream #1:0 (pcm_alaw) asplit:output2 -> Stream #2:0 (libmp3lame) which should be what you intended. HTH, please let us know how it works, Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
