In push mode (streaming), if the audio size is smaller than segment buffer size, it would be ignored. This happens because when the plugin receives an EOS signal while a single audio chunk that is less than the segment buffer size is buffered, it does not flush this chunk. The fix is to flush the data chunk when it receives an EOS signal and has a single (first) chunk buffered. How to reproduce: 1. Run gst-launch with tcp source ``` gst-launch-1.0 tcpserversrc port=3000 ! wavparse ignore-length=0 ! audioconvert ! filesink location=bug.wav ``` 2. Send a wav file with unspecified data chunk length (0). Attached a test file ``` cat test.wav | nc localhost 3000 ``` 3. Compare the length of the source file and output file ``` ls -l test.wav bug.wav -rw-rw-r-- 1 amr amr 0 Aug 15 11:07 bug.wav -rwxrwxr-x 1 amr amr 3564 Aug 15 11:06 test.wav ``` The expected length of the result of the gst-lauch pipeline should be the same as the test file minus the headers (44), which is ```3564 - 44 = 3520``` but the actual output length is ```0``` After the fix: ``` ls -l test.wav fix.wav -rw-rw-r-- 1 amr amr 3520 Aug 15 11:09 fix.wav -rwxrwxr-x 1 amr amr 3564 Aug 15 11:06 test.wav ``` |
