[FFmpeg-devel] [PATCH] avformat/movenc: correct ImageDescription depth for v210 v410

[Dave Rice]

This corrects a few values in the Image Description for v210 and v410 in mov. Apple defines what the depth value for these uncompressed formats should be in https://developer.apple.com/library/content/technotes/tn2162/_index.html <https://developer.apple.com/library/content/technotes/tn2162/_index.html>.
