You can take a look at the information output in the log ./objs/ffmpeg-encoder-__defaultVhost__-live-test-logo.log. It might be that your local /usr/local/bin/ffmpeg cannot recognize the encoder named aac.

I extracted the ffmpeg from the log and tried it: /usr/local/bin/ffmpeg -f flv -i rtmp://127.0.0.1:1935/live?vhost=defaultVhost/test -i ./doc/ffmpeg-logo.png -filter_complex overlay=10:10 -vcodec libx264 -b:v 300000 -r 20.00 -s 768x320 -aspect 768:320 -threads 2 -profile:v baseline -preset superfast -acodec acc -b:a 45000 -ar 44100 -ac 2 -f flv -y rtmp://127.0.0.1:1935/live/test_logo, and it can push the stream normally.

There is indeed this problem, the AAC encoder is just not good.

@winlinvip winlinvip added this to the 3.0 milestone Sep 10, 2021
@winlinvip winlinvip changed the title 学习转码功能时把acodec由libfdk_aac换成aac后，FFmpeg被多个拉起，导致无法生成对应转码数据流 When learning the transcoding function, after changing the acodec from libfdk_aac to aac, multiple instances of FFmpeg are launched, resulting in the inability to generate corresponding transcoded data streams.
