#8085(ffprobe:new): ffprobe - report if audio is vbr
#8085: ffprobe - report if audio is vbr -------------------------------------+------------------------------------- Reporter: | Type: cobaltjacket | enhancement Status: new | Priority: wish Component: ffprobe | Version: 4.2 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Currently, ffprobe reports an average bitrate for audio streams. It would be useful to not only report this, but also to report if a given stream is variable bitrate (VBR). As a human, I can guess this, but I am utilizing the JSON output from ffprobe programmatically. -- Ticket URL: <https://trac.ffmpeg.org/ticket/8085> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Could we add a key that indicates vbr vs. cbr? {{{ "format": { "filename": "Sultans of Swing.mp3", "nb_streams": 1, "nb_programs": 0, "format_name": "mp3", "format_long_name": "MP2/3 (MPEG audio layer 2/3)", "start_time": "0.000000", "duration": "346.435918", "size": "8759649", "bit_rate": "202280", "probe_score": 51, "tags": { "title": "Sultans of Swing", "artist": "Dire Straits", "genre": "Rock", "date": "1978" } }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/8085#comment:1> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
