  "message": "[LibvpxVp8Encoder] Allow I420A to be scaled to I420.\n\nIn Chromium, the I420ABufferInterface implementation uses the default\nCropAndScale() implementation which converts to I420 in the process.\n\nThis should be OK, because we do not encode the alpha channel anyway,\nso having WebRTC scaling ignore the alpha channel might even be a good\nthing. Unfortunatety, an if statement in the LibvpxVp8Encoder did not\nconsider I420A and I420 to be the same, resulting in dropping perfectly\nvalid frames.\n\nThis CL fixes that by considering I420A and I420 \"compatible\" in a\ncomparison helper function. The problem only happens in this encoder,\nso only this encoder needs to be fixed.\n\nTBR\u003dilnik@chromium.org,eshr@google.com\n\n(cherry picked from commit 065ce9cb227a86ca9c5cf1469a5edd9ffd7a662a)\n\nBug: chromium:1203206\nChange-Id: Iec434d4ada897c79e09914cac823148fd5b05e57\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/216323\nReviewed-by: Evan Shrubsole \u003ceshr@google.com\u003e\nReviewed-by: Ilya Nikolaevskiy \u003cilnik@webrtc.org\u003e\nCommit-Queue: Henrik Boström \u003chbos@webrtc.org\u003e\nCr-Original-Commit-Position: refs/heads/master@{#33845}\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/216682\nReviewed-by: Henrik Boström \u003chbos@webrtc.org\u003e\nReviewed-by: Markus Handell \u003chandellm@webrtc.org\u003e\nCr-Commit-Position: refs/branch-heads/4472@{#9}\nCr-Branched-From: 3e0c60ba4ef28a9f26fe991e5eec3150402c7dd3-refs/heads/master@{#33644}\n",
