Re: [FFmpeg-user] Right audio channel shifted
Alex wrote VLC still said: http://s14.directupload.net/images/141014/r7h73d5b.jpg One other thing: I checked my database again and I have to verify over 300 videos which are possibly affected by this bug. Is there a possibility with ffmpeg to repair those files automatically or at least see if a file is affected. Otherwise I am going to do this job manually via a vectorscope. :) Thanks, Alex Okay, when I check the trimmed file with ffmpeg it looks okay: C:\ffmpeg -i test_new.mxf ffmpeg version N-66809-g20df026 Copyright (c) 2000-2014 the FFmpeg developers built on Oct 11 2014 23:42:02 with gcc 4.9.1 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-avisynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libfreetype --enable-libgme --enable-libgsm --enable- libilbc --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libschroedinger --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvo-aacenc -- enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable-zlib libavutil 54. 10.100 / 54. 10.100 libavcodec 56. 4.101 / 56. 4.101 libavformat56. 9.100 / 56. 9.100 libavdevice56. 1.100 / 56. 1.100 libavfilter 5. 1.103 / 5. 1.103 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 1.100 / 1. 1.100 libpostproc53. 1.100 / 53. 1.100 [mxf @ 00350280] index entry 5095 + TemporalOffset 1 = 5096, which is out of bounds Guessed Channel Layout for Input Stream #0.1 : mono Guessed Channel Layout for Input Stream #0.2 : mono Input #0, mxf, from 'test_new.mxf': Metadata: uid : adab4424-2f25-4dc7-92ff-29bd000b generation_uid : adab4424-2f25-4dc7-92ff-29bd000b0001 company_name: FFmpeg product_name: OP1a Muxer product_version : 56.9.100 product_uid : adab4424-2f25-4dc7-92ff-29bd000b0002 modification_date: -01-01 00:00:00 timecode: 00:00:00:00 Duration: 00:03:32.55, start: 0.00, bitrate: 52515 kb/s Stream #0:0: Video: mpeg2video (4:2:2), yuv422p(tv, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 5 kb/s, 23.98 fps, 23.98 tbr, 23.98 tbn, 47.95 tbc Stream #0:1: Audio: pcm_s24le, 48000 Hz, 1 channels, s32 (24 bit), 1152 kb/s Stream #0:2: Audio: pcm_s24le, 48000 Hz, 1 channels, s32 (24 bit), 1152 kb/s But: [mxf @ 00350280] index entry 5095 + TemporalOffset 1 = 5096, which is out of bounds What does this mean?

Re: [FFmpeg-user] Right audio channel shifted
Hi Alex, I guess there is somehing wrong with the channel mapping, but without the fliter_complex the mapping seems to be okay. I think the filter_complex messes up the mapping. Note this mapping from your output: Stream mapping: Stream #0:2 (pcm_s24le) - atrim atrim - Stream #0:0 (pcm_s24le) Stream #0:0 - #0:1 (copy) and this result: Output #0, mxf, to 'test_new.mxf': Stream #0:0: Audio: pcm_s24le, 48000 Hz, mono, s32 (24 bit), 1152 kb/s Stream #0:1: Video: mpeg2video, yuv422p, 1920x1080 [SAR 1:1 DAR 16:9], and this warning: [mxf @ 003b69c0] there must be exactly one video stream and it must be the first one I'm sure that's your issue. The filter seems to be messing up the mapping, at least in this automatic case. Instead of C:\ffmpeg -i test.mxf -vcodec copy -map 0:v -acodec pcm_s24le -map 0:1 -map 0:2 -filter_complex [a:1]atrim=start=0.035 test_new.mxf you probably need something like ffmpeg -i test.mxf -vcodec copy -map 0:v -acodec pcm_s24le -map 0:1 -filter_complex [a:1]atrim=start=0.035[ashifted] -map [ashifted] test_new.mxf (Untested) Note that I'm trying to explicitly map the filter output to a particular stream, avoiding automatic mapping. You may have to play around a bit more with the map options. Is this a bug, BTW? Documentation on -map states: The first -map option on the command line specifies the source for output stream 0, the second -map option specifies the source for output stream 1, etc. Digging further, documentation of -filter_complex clarifies: Output link labels are referred to with ‘-map’. Unlabeled outputs are added to the first output file. So the first documentation section is somewhat unclear, as it is disturbed by the second behavior.

Re: [FFmpeg-user] Right audio channel shifted
Dear All, Just joined the mailing list. Looking for a video player in a browser, that will play: mp4 video codec, aac audio codec, and floor audio, en, fr, ger, tr translations. Each audio channel will be selected in the browser in most platforms. I have managed to: ffmpeg -i 00.mp4 -i 01.mp4 -i 02.mp4 -i 03.mp4 -map 0:0 -map 0:1 -map 1:0 -map 2:0 -map 3:0 -acodec copy -vcodec copy output.mp4 where output.mp4 is the video file with 4 audio stream muxed together. Now how can i play it in a browser.
