#4638(undetermined:new): Multithreaded FLAC encoding

#4638: Multithreaded FLAC encoding -------------------------------------+------------------------------------- Reporter: xtemp09 | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: Keywords: | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- I found that FLAC encoding utilizes only 100% of CPU, instead, e.g. 1200% (I have 12-core computer). It takes so long when encoding large files at maximum compression level. Could you add multithreading to FLAC encoding? Maybe, openCL would be help common users too. flaCCL, FlaCuda are multithreaded and have better compression than that one of ffmpeg. Could you include them into ffmpeg? I hope this request won't hang here 3-2 years like many others. :'( -- Ticket URL: <https://trac.ffmpeg.org/ticket/4638> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#4427: ffprobe read_intervals not correctly working with avi -------------------------------------+------------------------------------- Reporter: martinr92 | Type: defect Status: new | Priority: normal Component: ffprobe | Version: Keywords: | unspecified read_intervals | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: I'd like to receive the key frames of a avi video, that are in a range of 2-5 seconds. For this I'm using ffprobe {{{ ffprobe -print_format json -select_streams v -read_intervals 00:00:10%+2 -show_frames test.avi }}} It's a 25 fps video, so I should receive 50 frames + maybe some frames before second 10 (seeking to the key-frame). In this case, it starts with frame 195 (7,8 seconds) which is ok. {{{ { "frames": [ { "media_type": "video", "key_frame": 1, "pkt_dts": 195, "pkt_dts_time": "7.800000", "best_effort_timestamp": 195, "best_effort_timestamp_time": "7.800000", "pkt_duration": 1, "pkt_duration_time": "0.040000", "pkt_pos": "656024", "pkt_size": "28089", "width": 720, "height": 576, "pix_fmt": "yuv420p", "sample_aspect_ratio": "64:45", "pict_type": "I", "coded_picture_number": 0, "display_picture_number": 0, "interlaced_frame": 0, "top_field_first": 0, "repeat_pict": 0 }, { "media_type": "video", "key_frame": 0, "pkt_dts": 196, "pkt_dts_time": "7.840000", "best_effort_timestamp": 196, "best_effort_timestamp_time": "7.840000", "pkt_duration": 1, "pkt_duration_time": "0.040000", "pkt_pos": "697704", "pkt_size": "2325", "width": 720, "height": 576, "pix_fmt": "yuv420p", "sample_aspect_ratio": "64:45", "pict_type": "B", "coded_picture_number": 3, "display_picture_number": 0, "interlaced_frame": 0, "top_field_first": 0, "repeat_pict": 0 }, { "media_type": "video", "key_frame": 0, "pkt_dts": 197, "pkt_dts_time": "7.880000", "best_effort_timestamp": 197, "best_effort_timestamp_time": "7.880000", "pkt_duration": 1, "pkt_duration_time": "0.040000", "pkt_pos": "694028", "pkt_size": "2500", "width": 720, "height": 576, "pix_fmt": "yuv420p", "sample_aspect_ratio": "64:45", "pict_type": "B", "coded_picture_number": 2, "display_picture_number": 0, "interlaced_frame": 0, "top_field_first": 0, "repeat_pict": 0 }, [....] }}} Not ok for me is the end, because it should stop after frame 300 (second 12).
