最后一句话:Cannot find a matching stream for unlabeled input pad 1 on filter Parsed_amix_0 看不懂,官方文档也没有什么提示。 其实我的目的很简单,把音频和视频合并到一个输出即可,输出的时长取第一个输入文件或第二个输入文件展开 乘号痕 2021-07-29 00:17:33 1073 分享 版权 举报 0 条回答 写回...
pad filter 视频边界填充。具体参考http://ffmpeg.org/ffmpeg-filters.html#pad-1。 rotate filter 视频任意角度旋转。具体参考http://ffmpeg.org/ffmpeg-filters.html#rotate。 scale filter 使用libswscale库完成视频缩放的filter。 showinfo filter 显示视频帧的参数信息,比如时间戳、采样格式、帧类型等。

For example, in one embodiment, packed data can be operated on in one of four formats: a “packed byte” format (e.g., PADDb), a “packed word” format (e.g., PADDw), a “packed double word” (dword) format (e.g., PADDd); or a “packed quad word” (qword) format (e.g...

inputs->pad_idx = 0; inputs->next = NULL; outputs对应的是in(也就是buffer),in是Graph第一个Filter,所以它只有输出端(所以对应到了outputs)。 同理out(buffersink)是Graph最后一个Filter,只有输入端,因此对应到了inputs。 +---+ +---+ +---+ |buffer | |Filter ... Filter N| | buffersink ...
