A sample rate <= 0 is invalid.
Fixes an assert in ffmpeg_enc.c that assumed a valid sample rate would be set.

Should ensure avcodec_send_packet() doesn't return EAGAIN in scenarios where it's not
meant to (e.g., ffmpeg_dec.c where avcodec_receive_frame() is called in a loop to drain
all produced frames before trying to submit more packets).
Fixes ticket #11377.
