avformat/hlsenc: Check that data is set
If codecpar->extradata is not set (for example, when the stream goes through the 'tee' muxer), then a segfault occurs. This patch ensures the data variable is not null before attempting to access it Before the var_stream_map option was available - I was using the tee muxer to create each resolution as an individual stream. When running this configuration after the most recent hlsenc change I hit a segfault The most simple command which recreates the segfault is: ffmpeg -i in.ts -map 0:a -map 0:v -c:a aac -c:v h264 -f tee [select=\'a,v\':f=hls]tv_hls_hd.m3u8 Signed-off-by: Brendan McGrath <redmcg@redmandi.dyndns.org>
