如何解决FFMPEG处理MOV文件时失败

我正在尝试将视频文件转换为DASH格式。除了MOV 视频之外，所有视频都效果很好。

我正在使用以下命令：

/usr/local/bin/ffmpeg -y -i /path/to/mov/video.mov -c:v libx264 -c:a aac -bf 1 -keyint_min 25 -g 250 -sc_threshold 40 -use_timeline 1 -use_template 1 -init_seg_name 'video_init_$RepresentationID$.$ext$' -media_seg_name 'video_chunk_$RepresentationID$_$Number%05d$.$ext$' -seg_duration 10 -hls_playlist 0 -f dash -adaptation_sets -0:s -map 0 -s:v:0 854x480 -b:v:0 750k -strict -2 -threads 12 /output/path/video.mpd

我得到了错误：

Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument ... Error initializing output stream 0:1

完整的命令输出为：

我猜问题是文件包含两个非音频/视频流：如果不处理最后两个流（＃2和＃3），我找不到排除，忽略或复制的方法。

解决方法

要解决此问题，我必须从视频文件中删除所有流。

此答案可帮助我构建适当的ffmpeg命令，以在通过原始命令https://stackoverflow.com/a/38162168/10561527处理视频文件之前准备视频文件

无需事先准备文件。

仅地图视频和音频

您正在使用的-map 0包括所有流。我怀疑DASH混合器是否可以与其他流类型一起使用，例如数据（示例中的流#0:2和#0:3，字幕和附件）。

将-map 0更改为-map 0:v -map 0:a，以确保仅包含视频和音频。

您的-adaptation_sets错误

删除此选项并使用默认值，或阅读FFmpeg DASH muxer documentation对其进行修改。
