<div dir="ltr">Dear Sebastian,<div><br></div><div>Thanks for your reply.</div><div><br></div><div>The pipeline I'm using is uridecodebin ! encodebin ! filesink. The uri property of uridecodebin is configured for appsrc. My code is in python, and it is based on the example provided with the Livestreamer application. I set up the pads between uridecodebin and encodebin in the pad-added signal handler of uridecodebin.</div>
<div><br></div><div>I'm not sure what do you mean by "finalizing the file". Once I cannot push more buffers in the need-data signal handler, I send the end-of stream signal from the appsrc. I also have the eos message handler configured on the pipeline bus and once I have the message, I put the pipeline into NULL state and wait for the result with the get_state(timeout) function. Once this function returns, I quit the main loop. Should I do anything more or in a different way? Switching on logging on qtmux, filesink and the pipeline I find the followings in the log related to the file close...</div>

What's the pipeline you're using? Are you finalising the file once<br>
you're done by having an EOS event going into the muxer and waiting for<br>
the EOS message from the sink before shutting down the pipeline?<br>
