#9173: Underestimated required buffer size (prores 8K) ------------------------------------+----------------------------------- Reporter: 0kajuna0 | Owner: Type: defect | Status: new Priority: normal | Component: avcodec Version: git-master | Resolution: Keywords: prores | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ------------------------------------+----------------------------------- Comment (by mkver): 1. I could already reproduce the issue with [https://images.nasa.gov /details-First-8K-Video-from-Space.html a different sample]. Nevertheless thanks for the effort (have you btw selected FFmpeg as the project? I am asking because the sample hasn't appeared [https://samples.ffmpeg.org /ffmpeg-bugs/trac/ here] yet). 2. The problem is basically here: "frame size upper bound: 476932518". When converted to bits this gives a negative number in a 32bit, leading to nonsense check results. 3. When I test with an old build of 4.2, the outcome is only slightly different: It does not stops after having encountered an error; instead it just keeps on going, but the frames where the error have been encountered are dropped. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9173#comment:4> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
