最近需要把一批视频转换成mp3格式,方便放到mp3播放器上播放。 继续使用ffmpeg来实现: import subprocess def convert_video_to_audio(video_file_path, audio_file_path): command = f'ffmpeg -i "{video_file_path}" -vn -ar 44100 -ac 2 -b:a 192k "{audio_file_path}"' subprocess.call(command) ...
convert_to_mp3:函数用来调用 FFmpeg 将视频文件转换为 MP3 文件。 process_directory:函数扫描指定目录中的所有文件,并对扩展名为.mp4和.mkv的文件进行处理。 如果MP3 文件已存在,则跳过处理并打印提示信息。 如果MP3 文件不存在,则调用convert_to_mp3函数进行转换。
ffmpeg -i [Video File Name].mp4 [Audio File Name].mp3 The Video File Name in the command is the name of the MP4 video file that you want to convert. The Audio File Name in the command is the name of the MP3 audio file that you want. FFmpeg is the command to initiate the process...
ffmpeg -i test.wav -f mp3 -acodec libmp3lame -y wav2mp3.mp3 视频转换: 1.转换wmv到mp4: ffmpeg -i sample.wmv -vcodec libx264 -acodec aac out.mp4 2.抓取H264视频流: ffmpeg -i sample.flv -vcodec copy -vbsf h264_mp4toannexb -an out.h264 2.1 vbsf为过滤方法,即将flv规定的H264组织...
cd [Address of the folder containing the MP4 Video file] After that, type the below command: ffmpeg -i [Video File Name].mp4 [Audio File Name].mp3 The Video File Name in the command is the name of the MP4 video file that you want to convert. ...
ffmpeg -f dshow -i video=”Logitech HD Webcam C310” -vcodec libx264 -preset:v ultrafast -tune:v zerolatency e:\004.mp4 录一段视频,按q键停止. 播放: ffplay e:\\001.mkv 1. 音频录制 //test1 ffmpeg -f dshow -i audio="麦克风 (HD Webcam C310)" -acodec aac e:\\temp.aac ...

Yes running ffmpeg from the commandline works fine: ffmpeg -i in.mp4 -f mp4 out.mp3 Any idea what could be happening? I can also open the mp4 in vlc, quicktime etc and play it just fine. I am on Mac OS X. Also piping input to ffmpeg works as well ...
你打的命令其实没错，-i后面是输入视频路径，-c是视频编码 这些本身没啥问题，但是，mp4这种容器支持的...
这个例子我们演示把一个视频文件和一个音频文件合并成一个音视频文件,命令:ffmpeg -i 少年.mp3 -i benben.mp4 -acodec copy -vcodec copy recorder003.mp4 。生成的文件在播放过程中就包含了音频文件输入的声音。 执行命令的结果如下所示: [mp3 @ 0x7ffabc003000] Skipping 0 bytes of junk at 417. Input...
