Thanks for the info, but I think for compatibility reason software encoding should always be used by default, just like on other platforms. FFmpeg doesn't sort encoders that way. truboxlmentioned this issueMar 4, 2024 truboxlclosed this ascompletedin#19408Mar 5, 2024 ...
在FFmpeg 中,时间的管理是通过时间基(time_base)和时间戳(timestamp)来实现的,它们是处理音视频流中时间信息的核心概念。 时间基通常用分数来表示,表示一个单位时间内的时钟周期数,用于将媒体流中的时间表示为数字值,例如 1/1000 表示每毫秒的时钟周期数;时间戳通常以时间基为单位来表示,是指在视频流或者音频流...
You will want to copy the video stream without re-encoding to save a lot of time but re-encoding the audio might help to prevent incompatibilities: ffmpeg -i v.mp4 -i a.wav -c:v copy -map 0:v:0 -map 1:a:0 new.mp4 -map 0:v:0maps the first (index0) video stream from the...
MKV(Matroska Video)是一种开放的多媒体容器格式,支持多种字幕格式,其中包括:SRT(SubRip Subtitle)、VobSub(.sub/.idx)、SSA/ASS(SubStation Alpha)、PGS(Presentation Graphic Stream)等。 srt 格式字幕转换成 ass 格式命令: ffmpeg -i test.srt test.ass ...

FFmpeg can take the live input, decode it, and then re-encode it with the appropriate video codec, bitrate, and other parameters needed for the target streaming service. This process happens in real-time, allowing FFmpeg real-time encoding of the transcoded stream to the FFmpeg stream server ...
