@esmaily Thanks for this output, indeed there was a regex bug in parsing multiple streams, I’ve pushed a commit to fix it. You can try this fix by running following commands:

  # clone the repository and get inside
  git clone https://github.com/abhiTronix/vidgear.git && cd vidgear

  # checkout the latest `development` branch
  git checkout development

  # install normally
  pip3 install .

after enable sreamgear logging: ValueError [StreamGear:ERROR] :: Kindly provide a valid output value. Refer Docs for more information. /usr/local/lib/python3.8/site-packages/vidgear/gears/streamgear.py, line 225, in init /usr/local/bin/python 3.8.3

@esmaily That’s all? I need complete output from commandline to debug what is happening. Also check if path /usr/src/app/media/upload/ exist or not? If not, then run command mkdir -p /usr/src/app/media/upload first in docker and then specify path '/usr/src/app/media/upload/1609541608-vide-finnanc.mpd' in StreamGear.

ValueError [StreamGear:ERROR] :: Kindly provide a valid output value. Refer Docs for more information.

This means there is no value on output parameter at StreamGear, meaning your code is incorrect. If you need to enable logging you just do:

streamer = StreamGear(output=encodeUrl, logging=True, format="dash", **stream_params)

running ffmpeg -i video-finance.mp4 -filter_complex "[0]split=6[mid0][mid1];[mid0]scale=320:-1[out0];[mid1]scale=640:-1[out1]" -map [out0] -map 0:a -map [out1] -map 0:a -c:a aac -c:v:0 libx264 -c:v:1 libvpx-vp9 -use_timeline 1 -use_template 1 -window_size 6 -adaptation_sets "id=0,streams=v id=1,streams=a" -hls_playlist true -f dash output.mpd in bash it works but run this command in project with subprocess occer this error

Errno 2] No such file or directory: 'ffmpeg -i /usr/src/app/media/upload/2021/01/video-finance.mp4 -filter_complex "[0]split=6[mid0][mid1];[mid0]scale=320:-1[out0];[mid1]scale=640:-1[out1]" -map [out0] -map 0:a -map [out1] -map 0:a -c:a aac -c:v:0 libx264 -c:v:1 libvpx-vp9 -use_timeline 1 -use_template 1 -window_size 6 -adaptation_sets "id=0,streams=v id=1,streams=a" -hls_playlist true -f dash output.mpd'

But after append shell=True it works `subprocess.run(CMD,shell=True)`

how add shell=True in vidgear??

Why not valid path?
