@hadestyz I'll be able to look at this tomorrow

@subzeromot Please see the reference section on [Video Buffer Conversion](https://github.com/prominenceai/deepstream-services-library/blob/master/docs/api-source.md#video-buffer-conversion) Under the [Source documentation](https://github.com/prominenceai/deepstream-services-library/blob/master/docs/api-source.md) ...specifically [dsl_source_video_buffer_out_format_set](https://github.com/prominenceai/deepstream-services-library/blob/master/docs/api-source.md#dsl_source_video_buffer_out_format_set) to set the output format of your source to RGBA

@subzeromot ... There is definitely a problem here. What's interesting is that it works fine with just one source,  but fails with two sources... even with the same components...

Because they are failing to link to the streammuxer.. if you have logging on you will see the error messages. it's diffidently a race condition in the order the components...

@subzeromot I take that all back. Everything is working fine for me. I had missed changing the format on one of my sources. The following file uses to http uri...

Sorry @subzeromot , You're correct. I realized I was testing with my [v0.30.alpha](https://github.com/prominenceai/deepstream-services-library/tree/v0.30.alpha) dev branch. I have not had a chance to retest with the Master branch, but I have...

@subzeromot any update on this?

@subzeromot Please provide me with a log file so I can see where/why it is failing for you ``` export GST_DEBUG_FILE=./log.txt export GST_DEBUG=1,DSL4 ``` ... and I'm unable to expand...

@subzeromot this appears to be a different issue and I believe the problems is caused by this statement. ```python n_frame_c = pyds.get_nvds_buf_surface(hash(buffer), frame_meta.batch_id) ```` please remove the hash() and try...

@subzeromot I've been able to get this to work. The key is that the memory type must be changed to `DSL_NVBUF_MEM_TYPE_CUDA_UNIFIED`. See [get-nvds-buf-surface](https://docs.nvidia.com/metropolis/deepstream/5.0DP/python-api/Methods/methodsdoc.html#get-nvds-buf-surface) It is sufficient to do this at...
