[Statistics Filter]: What's the best way to calculate a meta-median?

I'm working with aggregated benchmarking data, and don't have access to the the raw data behind them. The benchmarks include averages, percentiles, number of measurements, and medians (usually no standard deviations or variances).
What would be the best way to calculate a meta-median, i.e. a median based on several median values from different benchmarks? Should I:
- take the median of medians
- average median values (maybe weighted?)
- use any other kind of approximation from the data I have?
Thanks for your help!
