#8272: "error reading header" of MOV file containing HDV stream -------------------------------------+------------------------------------- Reporter: obruchez | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I've created a MOV file using iMovie from an HDV tape (via Firewire). The file has a size of 11 GB. When using it as an input in ffmpeg, I get an error: {{{ ./ffmpeg -i 2005-07-01\ 23_23_13.mov ffmpeg version N-95322-g72704cbff4-tessus https://evermeet.cx/ffmpeg/ Copyright (c) 2000-2019 the FFmpeg developers built with Apple clang version 11.0.0 (clang-1100.0.33.8) configuration: --cc=/usr/bin/clang --prefix=/opt/ffmpeg --extra- version=tessus --enable-avisynth --enable-fontconfig --enable-gpl --enable-libaom --enable-libass --enable-libbluray --enable-libdav1d --enable-libfreetype --enable-libgsm --enable-libmodplug --enable- libmp3lame --enable-libmysofa --enable-libopencore-amrnb --enable- libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable- libopus --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvmaf --enable-libvo-amrwbenc --enable- libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable- libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable- libzimg --enable-libzmq --enable-libzvbi --enable-version3 --pkg-config- flags=--static --disable-ffplay libavutil 56. 35.100 / 56. 35.100 libavcodec 58. 59.102 / 58. 59.102 libavformat 58. 33.100 / 58. 33.100 libavdevice 58. 9.100 / 58. 9.100 libavfilter 7. 62.100 / 7. 62.100 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fac76001800] error reading header 2005-07-01 23_23_13.mov: Cannot allocate memory }}} It works perfectly fine in Quicktime Player. When I truncate the file e.g. to 100 MB, ffmpeg can open the file: {{{ ./ffmpeg -i 2005-07-01\ 23_23_13-truncated.mov ffmpeg version N-95322-g72704cbff4-tessus https://evermeet.cx/ffmpeg/ Copyright (c) 2000-2019 the FFmpeg developers built with Apple clang version 11.0.0 (clang-1100.0.33.8) configuration: --cc=/usr/bin/clang --prefix=/opt/ffmpeg --extra- version=tessus --enable-avisynth --enable-fontconfig --enable-gpl --enable-libaom --enable-libass --enable-libbluray --enable-libdav1d --enable-libfreetype --enable-libgsm --enable-libmodplug --enable- libmp3lame --enable-libmysofa --enable-libopencore-amrnb --enable- libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable- libopus --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvmaf --enable-libvo-amrwbenc --enable- libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable- libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable- libzimg --enable-libzmq --enable-libzvbi --enable-version3 --pkg-config- flags=--static --disable-ffplay libavutil 56. 35.100 / 56. 35.100 libavcodec 58. 59.102 / 58. 59.102 libavformat 58. 33.100 / 58. 33.100 libavdevice 58. 9.100 / 58. 9.100 libavfilter 7. 62.100 / 7. 62.100 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '2005-07-01 23_23_13-truncated.mov': Metadata: major_brand : qt minor_version : 0 compatible_brands: qt creation_time : 2019-10-08T13:02:06.000000Z com.apple.quicktime.make: Apple com.apple.quicktime.model: MacBookPro8,2 com.apple.quicktime.software: Mac OS X 10.13.6 (17G8037) com.apple.quicktime.creationdate: 2019-10-08T14:42:40+0200 Duration: 00:00:20.52, start: 0.000000, bitrate: 38985 kb/s Stream #0:0(und): Video: mpeg2video (Main) (hdv2 / 0x32766468), yuv420p(tv, bt709, top coded first (swapped)), 1440x1080 [SAR 4:3 DAR 16:9], 25000 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default) Metadata: creation_time : 2019-10-08T13:02:06.000000Z handler_name : Core Media Video encoder : HDV 1080i60 timecode : 00:00:00:15 Stream #0:1(und): Data: none (tmcd / 0x64636D74), 0 kb/s Metadata: creation_time : 2019-10-08T13:02:06.000000Z handler_name : Core Media Time Code timecode : 00:00:00:15 Stream #0:2(und): Audio: pcm_f32le (lpcm / 0x6D63706C), 48000 Hz, stereo, flt, 3072 kb/s (default) Metadata: creation_time : 2019-10-08T13:02:06.000000Z handler_name : Core Media Audio At least one output file must be specified }}} I would attach the full, verbose log to this ticket, but it's very big (12 GB uncompressed, 720 MB compressed). -- Ticket URL: <https://trac.ffmpeg.org/ticket/8272> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
