Typically only a small subset of the SDL texture formats are supported directly
by the SDL renderer drivers, the rest is software emulated. It's better if
libswscale does the format conversion to a hardware-accelerated texture format
instead of SDL.
This should fix video render slowdowns with some texture formats after
3bd2228d05.

Since a7da134742, flush packets are passed
to process_input_packet() during stream copy. This modifies the input
timestamp handling to ignore them - since they contain no data, timestamps
should not be affected.
It has no effect whatsoever since the major bump.
Replace the flag's documentation to reflect this as well.

Otherwise the frame size of the codec is not set in the buffersink.
Fixes ticket #6603 and the following simpler case:
ffmpeg -c aac -filter_complex "sine=d=0.1,asetnsamples=1025" out.aac

This has been unused for a long time, and the original purpose has been
replaced by the per-stream hwaccel_flags.

This is required for FLV files, for which duration_pts comes out to be zero.

Since af1761f7b5 ffmpeg waits for a frame in each
stream before writing the output header. If we are using threaded decoding for
attached pictures, we have to read till EOF to be able to finally flush the
decoder and output the decoded frame. This essentially makes ffmpeg buffer all
non-attached picture packets, which will cause a "Too many packets buffered for
output stream" eventually.
By forcing single threaded decoding, we get a frame from a single packet as
well and we can avoid the error.
Fixes part of ticket #6375:
ffmpeg -i 46564100.mp3 -acodec libmp3lame -ab 128k -ac 2 out.mp3
