How to pass parameter to bitstream filter in ffmpeg with tee option?

I'm actually in a student project. The aim of this project is to develop bitstream filter (bsf) in ffmpeg (no problem for this). I need to access parameter in this bitstream filter from the command line, this actually work fine in simple command line:

./ffmpeg -i input.mp4 -vcodec copy -bsf my_bsf=1 -an -y output.264

But i need to duplicate my output with "tee" option, in this case i cannot make it work.. :

./ffmpeg -i input.mp4 -map 0 -vcodec copy -an -f tee "[bsfs/v=my_bsf1=1]output1.264|[bsfs/v=my_bsf2]output2.264"

The output of ffmpeg: Error parsing bitstream filter sequence

Any help?

Solution

  • The string parser needs opt=val syntax, so [bsfs/v=my_bsf1=optname=1]
