[FFmpeg-devel] [PATCH 2/3] retry_transfer_wrapper: check url_interrupt_cb at the end.

[Luca Barbato]

From: Nicolas George <nicolas.george at normalesup.org>

Checking it too early causes ffmpeg to fail to write the trailer of its
output files if it was interrupted with the 'q' keystroke.

Note that when a protocol is interrupted by url_interrupt_cb, some data may
be silently discarded: the protocol context is not suitable for anything
anymore.
