how to stream h265 video from ffmpeg to amazon s3?

I am trying to stream h265 video to aws s3 from ffmpeg, here is the command that i use:

ffmpeg -f gdigrab -i desktop -r 1 -vframes 5 -c:v libx265 -crf 40 -f mp4 pipe:1 | aws s3 cp -  s3://videosbuket-009212/d5.mp4

and error information:

[mp4 @ 000001c49541bb40] muxer does not support non seekable output
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
Error initializing output stream 0:0 --

what's wrong here?

Solution

  • What’s wrong is that mp4 does not support non seekable output. Just like the error reads. Use a format that doesn’t not requires seeking, like mkv. If you require mp4, then you must make a local copy first.
