![FFmpeg 无法将 MOV 转换为 FLV](https://linux22.com/image/1352952/FFmpeg%20%E6%97%A0%E6%B3%95%E5%B0%86%20MOV%20%E8%BD%AC%E6%8D%A2%E4%B8%BA%20FLV.png)
当我尝试将 .mov 文件转换为 .flv 时,我得到了这种类型的输出。
我收到错误
样本格式无效‘(null)’打开过滤器时出错!。
当我转换 .avi 或 .mp4 时,没有出现任何错误。我在 Windows 上。
ffmpeg -i C:/wamp/www/\ds_uploads\62\video\23c4a54cbf8bc73056cb370ae7371848.mov -y -f flv -ar 44100 -q:v 0 C:/wamp/www/\ds_uploads\62\video\23c4a54cbf8bc73056cb370ae7371848.flv 2>&1

答案1
ffmpeg 无法解码第一个版本 QDesign Music Codec (QDMC) 音频,尽管它可以解码 QDM2:
$ ffmpeg -codecs
D..... = Decoding supported
.E.... = Encoding supported
..V... = Video codec
..A... = Audio codec
..S... = Subtitle codec
...I.. = Intra frame-only codec
....L. = Lossy compression
.....S = Lossless compression
D.A.L. qdm2 QDesign Music Codec 2
..A.L. qdmc QDesign Music
另请参阅多媒体 Wiki:QDesign 音乐编解码器。您可能能够使用mplayer
(使用 w32codecs 支持)解码音频,然后将输出传送到 ffmpeg 进行编码。(示例命令对于这个答案来说是一个很好的编辑)。
