This commit fixes a memleak in the hls muxer when one uses a single file
as output. It has been forgotten to free the temporary buffers used to write
the packets so that the size of the leaks basically amounts to the size
of the output file. This commit adds the necessary free.

A threshold of 1 is sufficient for simple_dump_cut.webm, 10 is used
just to be sure the next truncated file doesnt cause the same issue

Obvious alternative fixes are to simply accept that the file is broken or to
write some advanced error concealment or to
simply accept that the decoder wont stop at the end of input.

Fixes: Ticket 8069 (artifacts not the differing md5 which was there before 1afd2469)
Fixes: simple_dump_cut.webm
Fixes: regression of 1afd2469

* FFmpeg retrieves a packet from the bitstream
* It attempts to get an input buffer (from its own list or by dequeuing one from the driver)
* If no input buffer is found, the bitstream packet is dropped instead of scheduled for trying again later

It's an issue that showed especially at high speeds (like using `-f null -` as output parameters).

Without this ffmpeg will attempt to copy the dts from the
most recently enqueued packet into the most recently dequeued
frame, which does not account for the buffering inside v4l2
and is not accurate.
Signed-off-by: Aman Gupta <aman@tmm1.net>

Frames are generally dequeued into capture buffers, so using
the output properties here was incorrect. It happened to work
fine for decoding, since the output/capture buffers have the same
dimensions.

For the v4l2 scaler, the dimensions can be different between output
and capture. Using the buffer's associated context makes this code
work correctly regardless of where the frame is coming from.
