commit c15a2a517b71746cfbcc4665df860fca88f535fe Author: Kacper Michajłow <[email protected]> AuthorDate: Thu Sep 10 03:47:46 2026 +0200 Commit: Kacper Michajłow <[email protected]> CommitDate: Wed Sep 23 13:46:13 2026 +0000 fate/vcodec: cover the encoder taking the input picture by reference An mpegvideo encoder takes the input picture by reference when its linesize matches the one the encoder uses itself, which is the coded width plus a border on either side, and copies the picture otherwise. Both have to encode the same. fate-vsynth1-mpeg4-adap feeds the encoder an unpadded picture, which gets copied. Pad the input to 352 + 2 * 16 and the same encode has the picture taken by reference instead, so the two cover a path each. The two references do not agree, which is the bug the next commit fixes.
