Bug 1472: Enhance GLMediaPlayer AV Sync: Fix FFMPEGMediaPlayer's audio resample: Use swr_get_out_samples(..) to calculate the required output sample count

Notable when playing audio with e.g. 24k sample rate on a 48k OpenAL ALAudioSink,
the sample duration was cut in half due to erroneous resampling missing half the required samples.

Using swr_get_out_samples(..) resolves this issue pre swr_convert(..), the resampling.
