#2686: Native AAC encoder collapses at high bitrates on some samples -------------------------------------+------------------------------------- Reporter: Kamedo2 | Owner: Type: defect | Status: open Priority: normal | Component: avcodec Version: git-master | Resolution: Keywords: aac | Blocked By: regression | Reproduced by developer: 1 Blocking: | Analyzed by developer: 0 | -------------------------------------+-------------------------------------
Comment (by Kamedo2): comment:185 was tested, along with qaac(Apple AAC). Apple AAC is a very good encoder, so the bitrate it uses must be close to the optimal. [[Image(http://i40.tinypic.com/2cok3rn.png)]] -q:a 0.3 vs -q:a 0.7 vs -q:a 0.7 vs -vbr 3 vs --tvbr 63 vs -V5 Std.bitrate is 127.5, 127.0, 126.9, 126.9, 126.2, 129.9, all of them are very close to 128k. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/2686#comment:190> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac
