Public bug reported: I have a lot of MOV files created by Canon EOS 7D. Unfortunately I didn't set date/time in time so I needed to change "creation_time", i.e. to remux MOV files with "-metadata creation_time=...",
e.g. avconv -i MVI_0007.MOV -vcodec copy -acodec copy -metadata creation_time="2011-02-04 13:23:35" MVI_0007.avconv.MOV The resulting MOV file turned to be a problem. Neither totem nor Popcorn Hour A-400 could play it's audio track. And here is why: mantonyan@mantonyan:~/Desktop/mtimecorrector$ diff -u MVI_0007.MOV.mediainfo MVI_0007.avconv.MOV.mediainfo --- MVI_0007.MOV.mediainfo 2013-05-15 14:22:11.435335721 +0400 +++ MVI_0007.avconv.MOV.mediainfo 2013-05-15 14:52:18.871333390 +0400 @@ -1,13 +1,14 @@ General -Complete name : MVI_0007.MOV +Complete name : MVI_0007.avconv.MOV Format : MPEG-4 Format profile : QuickTime Codec ID : qt File size : 97.9 MiB Duration : 18s 160ms Overall bit rate : 45.2 Mbps -Encoded date : UTC 2009-01-01 00:13:44 -Tagged date : UTC 2009-01-01 00:13:44 +Encoded date : UTC 2011-02-04 13:23:35 +Tagged date : UTC 2011-02-04 13:23:35 +Writing application : Lavf53.21.1 Video ID : 1 @@ -34,8 +35,8 @@ Bits/(Pixel*Frame) : 0.843 Stream size : 94.6 MiB (97%) Language : English -Encoded date : UTC 2009-01-01 00:13:44 -Tagged date : UTC 2009-01-01 00:13:44 +Encoded date : UTC 2011-02-04 13:23:35 +Tagged date : UTC 2011-02-04 13:23:35 Color primaries : BT.709 Transfer characteristics : BT.709 Matrix coefficients : BT.601 @@ -43,9 +44,9 @@ Audio ID : 2 Format : PCM -Format settings, Endianness : Little -Format settings, Sign : Signed -Codec ID : sowt +Format settings, Endianness : Big +Format settings, Sign : Unsigned +Codec ID : lpcm Duration : 18s 160ms Bit rate mode : Constant Bit rate : 1 536 Kbps @@ -55,7 +56,7 @@ Bit depth : 16 bits Stream size : 3.33 MiB (3%) Language : English -Encoded date : UTC 2009-01-01 00:13:44 -Tagged date : UTC 2009-01-01 00:13:44 +Encoded date : UTC 2011-02-04 13:23:35 +Tagged date : UTC 2011-02-04 13:23:35 "little-endian signed sowt" got converted to "big-endian unsigned lpcm". Than I tried doing the same with http://ffmpeg.gusari.org/static/64bit/ffmpeg.static.64bit.2013-05-15.tar.gz e.g. ~/Desktop/ffmpeg.static.64bit.2013-05-15/ffmpeg -i MVI_0007.MOV -vcodec copy -acodec copy -metadata creation_time="2011-02-04 13:23:35" MVI_0007.ffmpeg.MOV Surprisingly the resulting MOV was correct, i.e. "little-endian signed sowt" got converted to "little-endian signed sowt" (!). Thus ffmpeg converted the MOV file correctly whereas avconv didn't which led me to a conclusion that maybe there is a bug in avconv.
