get connection closed error when sending long file to Streaming Server from online_websocket_client_decode_file

[Caet-pip]

Hello I get the following error when sending a long file >50 mins. File format is 16k sampling rate.

could you post complete.logs and describe how to.reproduce it?

Sure,

the audio file I am sending is from a public repo: https://github.com/revdotcom/speech-datasets/blob/main/earnings21/media/4320211.mp3

I converted it to .wav format with 16k sampling rate using ffmpeg

I am sending a 55 plus minute audio file using this command:

python3 online-websocket-client-decode-file.py --server-addr localhost --server-port 6005 --seconds-per-message 0.1 --samples-per-message 16000 ./test_audio/4320211.wav

I start the server using this command:

python3 streming_server_tests.py --tokens=./sherpa-onnx-streaming-zipformer-en-2023-06-21/tokens.txt --encoder=./sherpa-onnx-streaming-zipformer-en-2023-06-21/encoder-epoch-99-avg-1.onnx --decoder=./sherpa-onnx-streaming-zipformer-en-2023-06-21/decoder-epoch-99-avg-1.onnx --joiner=./sherpa-onnx-streaming-zipformer-en-2023-06-21/joiner-epoch-99-avg-1.onnx --port=6005

This is the error log: Traceback (most recent call last): File "/home/sherpa-onnx/python-api-examples/lib/python3.12/site-packages/websockets/legacy/protocol.py", line 1289, in close_connection await self.transfer_data_task File "/home/sherpa-onnx/python-api-examples/lib/python3.12/site-packages/websockets/legacy/protocol.py", line 955, in transfer_data message = await self.read_message() ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/sherpa-onnx/python-api-examples/lib/python3.12/site-packages/websockets/legacy/protocol.py", line 1025, in read_message frame = await self.read_data_frame(max_size=self.max_size) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/sherpa-onnx/python-api-examples/lib/python3.12/site-packages/websockets/legacy/protocol.py", line 1100, in read_data_frame frame = await self.read_frame(max_size) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/sherpa-onnx/python-api-examples/lib/python3.12/site-packages/websockets/legacy/protocol.py", line 1157, in read_frame frame = await Frame.read( ^^^^^^^^^^^^^^^^^ File "/home/sherpa-onnx/python-api-examples/lib/python3.12/site-packages/websockets/legacy/framing.py", line 68, in read data = await reader(2) ^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/asyncio/streams.py", line 752, in readexactly await self._wait_for_data('readexactly') File "/usr/lib/python3.12/asyncio/streams.py", line 545, in _wait_for_data await self._waiter asyncio.exceptions.CancelledError

I start the server using this command:

python3 streming_server_tests.py

What is inside streming_server_tests.py?

[Caet-pip]

It is the same as streaming_server.py. I had to change the name as I had multiple files. I tried again with the streaming_server.py file from GitHub, and get same error in the online wbesocket client decode file logs:

Could you add some log messages in your client code and try to find how many samples it has sent before it throws?
