Hi All, I am having a strange problem splicing some files back together where when I splice the files back together ffplay reporting: [h264 @ 0x7fe002024000] Reinit context to 640x368, pix_fmt: yuv420p
This seems to cause a number of players to have issues that causes the audio to go out of sync. Example here: http://bucket01.mscreentv.com.s3.amazonaws.com/ffmpeg_tests/test_out.mp4 The only indicators I have on what might be going wrong is this + some warnings in the concat command see below, noting that all the files that are spliced together are 640x360 (also see below) Encoding video that is spliced in: ffmpeg -i http://msntest.serving-sys.com/BurstingRes/Site-1122/Type-16/61e59778-0f4a-4d63-af0d-63cf0179a6be.mp4 -c:v libx264 -c:a libfdk_aac -s 640x360 -t 5 -r 25 -profile:v main testad.ts ffmpeg version N-64602-g9195c26 Copyright (c) 2000-2014 the FFmpeg developers built on Jul 11 2014 15:41:21 with Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn) configuration: --enable-libx264 --enable-libfdk_aac --enable-nonfree --enable-gpl --enable-ffplay --enable-libfreetype libavutil 52. 92.100 / 52. 92.100 libavcodec 55. 69.100 / 55. 69.100 libavformat 55. 45.100 / 55. 45.100 libavdevice 55. 13.102 / 55. 13.102 libavfilter 4. 10.100 / 4. 10.100 libswscale 2. 6.100 / 2. 6.100 libswresample 0. 19.100 / 0. 19.100 libpostproc 52. 3.100 / 52. 3.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from ' http://msntest.serving-sys.com/BurstingRes/Site-1122/Type-16/61e59778-0f4a-4d63-af0d-63cf0179a6be.mp4 ': Metadata: major_brand : M4V minor_version : 1 compatible_brands: M4V mp42isom creation_time : 2014-05-23 03:22:24 Duration: 00:00:30.04, start: 0.000000, bitrate: 554 kb/s Stream #0:0(eng): Video: h264 (Baseline) (avc1 / 0x31637661), yuv420p(tv), 640x360 [SAR 1:1 DAR 16:9], 393 kb/s, 25 fps, 25 tbr, 25k tbn, 50 tbc (default) Metadata: creation_time : 2014-05-23 03:22:24 handler_name : Mainconcept MP4 Video Media Handler encoder : AVC Coding Stream #0:1(eng): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 157 kb/s (default) Metadata: creation_time : 2014-05-23 03:22:24 handler_name : Mainconcept MP4 Sound Media Handler File 'testad.ts' already exists.
