be583c6fd3 avcodec/h264: remove redundant and bogus get_format call
The AVCodecContext.get_format callback is not only used for pixel format
negotiation with the API user, but also for hwaccel init. For the
latter, it's required that some codec parameters, in particular the
codec profile, are set when the callback is invoked.

This patch removes a get_format invocation where this is not guaranteed.
The codec parameters, including the profile, are really set further
below. (The same code path that sets the profile also calls get_format
properly too.)

This just happened to work by coincidence in most cases. For example, if
the API user just copied or reused the AVStream's AVCodecContext when
decoding, the profile would be set properly. But in some cases it
fails., such as with the sample WolfensteinTwitch.mp4 on the samples
server.

Remove the redundant get_format call. Apparently it serves no purpose
anymore, although it is possible that this was different at the time it
was added in commit ffd77f94a2.

This fixes hwaccel usage for API users which do not set the profile
when setting up the AVCodecContext (which is allowed).

9099079488 avformat/hls: add support for EXT-X-MAP
Without EXT-X-MAP support we miss the first bytes of some streams.

These streams worked by luck before byte-ranged segment support was added in

Fixes ticket #4797.

fd74d45d51 avformat/hls: fix segment selection regression on track changes of live streams
Commit ad701326b4 ("avformat/hls: open playlists immediately when
AVDISCARD_ALL is dropped") inadvertently caused first_packet to never be
cleared, causing select_cur_seq_no() to not use the specific code for
live streams.

In practice this means that when the user selects a different audio
track during live stream (i.e. non-VOD) playback, there may be some
additional delay as the code might select an incorrect segment at first,
and we have to wait for video to catch audio (if too late segment was
selected) or to download more following audio segments (if too early
segment was selected).

Fix that by restoring the zeroing of first_packet.

dbb03b8e47 ffmpeg_opt: rename loop option to stream_loop
The "loop" option is used in several demuxers (like img2dec) and muxers, using the same name in ffmpeg_opt
breaks them. Feel free to revert this and replace by any other solution or rename both as preferred
This is just as a quick fix to avoid the regression with existing command lines and to have both named
the same (which does not work)

Example:
./ffmpeg -loop 1 -i fate-suite/png1/lena-rgb24.png -t 1 test.avi
will produce 25 frames with the img2dec loop but only 1 frame at 25fps with the ffmpeg loop option

6aaac24d72 avfilter/all: propagate errors of functions from avfilter/formats
Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM).
This propagates the return values.

All of these were found by using av_warn_unused_result, demonstrating its utility.

Tested with FATE. I am least sure of the changes to avfilter/filtergraph,
since I don't know what/how reduce_format is intended to behave and how it should
react to errors.
