Starting with a mono, 24bit, 48kHz audio file. 2. Adding 3 new channels leads to 3 additional, silent channels. 3.

#9409: Embedding some mp4 subtitles causes ffmpeg to hang -------------------------------------+------------------------------------- Reporter: Frank | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: subtitles | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I've run into a bug when trying to embed some subtitles into an MP4 file, ffmpeg hangs indefinitely with 100% cpu usage on one thread. When this happens the output file stops growing and what is usually a few seconds job simply does not finish even if left for hours. This only started happening recently with some videos downloaded from youtube-dl. I've tested this and it seems to be an issue with the latest version of every 4.x branch - 4.0.6, 4.1.6, 4.2.4, 4.3.2, and the latest git build. ffmpeg completes if I try this with the latest 3.4.8 branch, but the subtitles are broken and do not appear when selected. Since I'm not sure where the problem is in the subtitle I can't cut out the problem part here for an example. I will attach one of the subtitle files that causes the issue and include the youtube-dl command that will download the smallest video. youtube-dl command: {{{ youtube-dl.exe -v -f 160+249 --merge-output-format mp4 --sub-lang bn --write-auto-sub --embed-subs 0UlUbeaBCTg }}} ffmpeg command being run by youtube-dl: {{{ ffmpeg -y -loglevel "repeat+info" -i "file:Making Flavored Rum _ Easy and Cheap! - Part 1-0UlUbeaBCTg.mp4" -i "file:Making Flavored Rum _ Easy and Cheap! - Part 1-0UlUbeaBCTg.bn.vtt" -map 0 -c copy -map "-0:s" -map "-0:d" "-c:s" mov_text -map "1:0" "-metadata:s:s:0" "language=ben" "file:Making Flavored Rum _ Easy and Cheap! - Part 1-0UlUbeaBCTg.temp.mp4" }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/9409> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Though the given options are not enough to correctly open the codec, (the error `[h264_vaapi @ 0x55fc49a13c00] A hardware frames reference is required to associate the encoding device.` is reported). Libavcodec then proceeds to segfault. Preferably ffmpeg would not segfault when provided well formed input. Marking important as its a crash, feel free to re-prioritize if thats not the correct choice. Also preferably a fix would be backported if possible. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9537> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

But unfortunately when analyzing the same file with ffprobe, we don't get the rotate information. How to reproduce: {{{ % ffprobe -i input -of json -show_streams -show_format ffprobe / ffmpeg built from master built on debian }}} Result: {{{ { Input #0, jpeg_pipe, from '036538dd-700c-4884-9bf4-da1f4d85baed': Duration: N/A, bitrate: N/A Stream #0:0: Video: mjpeg (Baseline), yuvj420p(pc, bt470bg/unknown/unknown), 1280x960 [SAR 72:72 DAR 4:3], 25 fps, 25 tbr, 25 tbn "streams": [ { "index": 0, "codec_name": "mjpeg", "codec_long_name": "Motion JPEG", "profile": "Baseline", "codec_type": "video", "codec_tag_string": "[0][0][0][0]", "codec_tag": "0x0000", "width": 1280, "height": 960, "coded_width": 1280, "coded_height": 960, "closed_captions": 0, "film_grain": 0, "has_b_frames": 0, "sample_aspect_ratio": "1:1", "display_aspect_ratio": "4:3", "pix_fmt": "yuvj420p", "level": -99, "color_range": "pc", "color_space": "bt470bg", "chroma_location": "center", "refs": 1, "r_frame_rate": "25/1", "avg_frame_rate": "25/1", "time_base": "1/25", "bits_per_raw_sample": "8", "disposition": { "default": 0, "dub": 0, "original": 0, "comment": 0, "lyrics": 0, "karaoke": 0, "forced": 0, "hearing_impaired": 0, "visual_impaired": 0, "clean_effects": 0, "attached_pic": 0, "timed_thumbnails": 0, "captions": 0, "descriptions": 0, "metadata": 0, "dependent": 0, "still_image": 0 } } ], "format": { "filename": "036538dd-700c-4884-9bf4-da1f4d85baed", "nb_streams": 1, "nb_programs": 0, "format_name": "jpeg_pipe", "format_long_name": "piped jpeg sequence", "size": "272927", "probe_score": 26 } } }}} We can see there is no informations about the rotate metadata. But when reencoding: {{{ ffmpeg -y -loop 1 -t 5 -f image2 -i input output.mp4 ffprobe -i output.mp4 -of json -show_streams -show_format }}} Result: {{{ { Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'output.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf59.9.102 Duration: 00:00:05.00, start: 0.000000, bitrate: 351 kb/s Stream #0:0[0x1](und): Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc, bt470bg/unknown/unknown, progressive), 960x1280 [SAR 1:1 DAR 3:4], 347 kb/s, 25 fps, 25 tbr, 12800 tbn (default) Metadata: handler_name : VideoHandler vendor_id : [0][0][0][0] "streams": [ { "index": 0, "codec_name": "h264", "codec_long_name": "H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10", "profile": "High", "codec_type": "video", "codec_tag_string": "avc1", "codec_tag": "0x31637661", "width": 960, "height": 1280, "coded_width": 960, "coded_height": 1280, "closed_captions": 0, "film_grain": 0, "has_b_frames": 2, "sample_aspect_ratio": "1:1", "display_aspect_ratio": "3:4", "pix_fmt": "yuvj420p", "level": 32, "color_range": "pc", "color_space": "bt470bg", "chroma_location": "center", "field_order": "progressive", "refs": 1, "is_avc": "true", "nal_length_size": "4", "id": "0x1", "r_frame_rate": "25/1", "avg_frame_rate": "25/1", "time_base": "1/12800", "start_pts": 0, "start_time": "0.000000", "duration_ts": 64000, "duration": "5.000000", "bit_rate": "347878", "bits_per_raw_sample": "8", "nb_frames": "125", "extradata_size": 51, "disposition": { "default": 1, "dub": 0, "original": 0, "comment": 0, "lyrics": 0, "karaoke": 0, "forced": 0, "hearing_impaired": 0, "visual_impaired": 0, "clean_effects": 0, "attached_pic": 0, "timed_thumbnails": 0, "captions": 0, "descriptions": 0, "metadata": 0, "dependent": 0, "still_image": 0 }, "tags": { "language": "und", "handler_name": "VideoHandler", "vendor_id": "[0][0][0][0]" } } ], "format": { "filename": "output.mp4", "nb_streams": 1, "nb_programs": 0, "format_name": "mov,mp4,m4a,3gp,3g2,mj2", "format_long_name": "QuickTime / MOV", "start_time": "0.000000", "duration": "5.000000", "size": "219803", "bit_rate": "351684", "probe_score": 100, "tags": { "major_brand": "isom", "minor_version": "512", "compatible_brands": "isomiso2avc1mp41", "encoder": "Lavf59.9.102" } } } }}} We can see the resolution is not the same in output because the mjpeg decoder automatically rotate the frame. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9542> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
