avformat/rka: Fix 1/0 with bps=1 Fixes: division by zero Fixes: 55940/clusterfuzz-testcase-minimized-ffmpeg_IO_DEMUXER_fuzzer-6333107679920128 The decoder does not support bps=1 and i have no such sample so it is not known if this duration is correct. Alternatively we could error out on all bps we currently do not support on the decoder side or not set duration.
