FFmpeg : create data streams in MP4 container
28 mars 2022, par SoerenIs there a way to make FFmpeg create data streams in MP4 or Quicktime (.mov) containers ? I have tried
-attach ...
(works fine for Matroska containers, but not MP4/MOV) or-codec bin_data
, but to no avail.

-attach ...
technically creates streams with codec type "attachment", which are different from data streams. And while FFmpeg isn't smart enough to directly create data streams in containers where attachment streams aren't supported (ie. MP4), a two-step approach works :

ffmpeg -i <some media="media" file="file"> -attach <some file="file"> -metadata:s:2 mimetype=<data mime="mime" type="type"> -map 0:v -map 0:a -codec copy attached.mkv
ffmpeg -i attached.mkv -codec copy attached.mp4
</data></some></some>


The first command creates a Matroska file that contains a stream with
codec_type=attachment
. The second command then simply re-packages this into an MP4 container, turning the attachment stream into a data stream (codec_type=data
). So the question is : could this be combined into a single step ?

download livestream real-time data
15 juillet 2024, par Chenguang HeI'm working on a project to design a RTMP server in Java to get livestream data and download to flv file. One requirement is that to capture the real-time data, I need to download the recording for every second instead of downloading entire recording when livestream stop. Is there any way to achieve it ? Thanks


tried to download stream into byte array for every second and decode to flv using H.264 but didn't work.
