2022-05-02doc/examples/transcode_aac: Don't ignore last encoded frameAndreas Unterweger
The last encoded frame is now fetched on EOF. It was previously left in the encoder and caused a "1 frame left in queue" warning. Signed-off-by: Andreas Unterweger <dustsigns@gmail.com>

2022-03-25doc/examples/muxing: Remove outdated commentAndreas Rheinhardt
This comment only applies to the scenario in which one uses the AVCodecContexts embedded in AVStreams. Yet this code sample stopped doing so in 9897d9f4e074cdc6c7f2409885ddefe300f18dc7; and the last major version bump even removed the public AVCodecContexts in AVStreams. So just remove this comment.

They use non-public functions, which is unacceptable for a public API example. Rename the example back to avio_list_dir. This effectively reverts c84d208c275d6a43b3c3421d38772179abf8acee and 767d780ec001167b2fd8f6cfe4ef78a3a8b1e34c.
