probably disabled. Please choose an encoder manually.使⽤Google搜索后发现问题原因在于只有mp3的解码库，没有mp3编码库导致的，需要添加libmp3lame第三⽅库。libmp3lame第三⽅库安装⽅法:下载 libmp3lame源码压缩包并解压 打开命令⾏窗⼝并cd进⼊libmp3l

Please choose an encoder manually. 然后我通过自行执行编码器,依然不能成功: ffmpeg -i /Users/xxx/xxx.mov -b:v 96k -codec:v mpeg4 -s 480x816 /Users/xxx/xxx.mp4 转码失败:Unknown encoder 'mpeg4' 希望能得到您的帮助Contributor bbcallen commented Nov 1, 2016 No. ffmpeg in ijkplayer ...
libwavpack并允许构建libwavpack编码器，除非它是 使用–disable-encoder = libwavpack专门禁用。
Must be an integer between -1 and 16. 0 means that B-frames are disabled. If a value of -1 is used, it will choose an automatic value depending on the encoder. Default value is 0. b_qfactor float (encoding,video) Set qp factor between P and B frames. codec_tag integer bug flags...
* This is used to work around some encoder bugs. * A demuxer should set this to what is stored in the field used to identify the codec. * If there are multiple such fields in a container then the demuxer should choose the one * which maximizes the information about the used codec. *...
ffmpeg does not validate if the specified encoder can convert the selected stream or if the converted stream is acceptable within the output format. This applies generally as well: when the user sets an encoder manually, the stream selection process cannot check if the encoded stream can be ...
