Description
Summary of the bug:
I am trying to transcode from flv(VP6+mp3) video to mp4(avc+aac-le) format,
with our(saccubus team) mod verison of ffmpeg in Windows OS(7 or 8.1 or 10).
I could transcode that kind of flv to mp4 older than n2.8 mod,
but I cannot transcode now with newer than n2.8.2 version of ffmpeg ,not only mod but also original ffmpeg(windows binary of https://ffmpeg.zeranoe.com/builds/).
How to reproduce:
My trial of latest version is (using mingw_w64-32-i686 + msys2)
% ffmpeg.exe -analyzeduration 30M -probesize 30M -y -i flv_width_hight_unrecognizable.flv -threads 0 -s 512x384 -acodec aac -ab 128k -ar 44100 -ac 2 -vcodec libx264 -crf 23 -b 1400k -bt 2000k -maxrate 2000k -bufsize 2000k -async 1 -coder 1 -sws_flags lanczos -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -me_method umh -subq 8 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -b_strategy 2 -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -bf 3 -refs 3 -direct-pred auto -trellis 1 -weightp 1 -mixed-refs 1 -8x8dct 1 -fast-pskip 1 -pix_fmt yuv420p output.mp4

Where is the sample?
And where can I find your modified version of FFmpeg?
comment:2 by , 9 years ago
The modified version of FFmpeg is here,
https://github.com/Saccubus/ffmpeg/tree/Saccubus1
build script mod
https://github.com/Saccubus/ffmpeg-windows-build-helpers/tree/saccubus
and other required software (to access video site via network)
but this dooes not relate to this problem I think.
https://github.com/Saccubus/Saccubus1.x
About the sample, I have not submitted yet,
since I cannot connect to ftp://upload.ffmpeg.org. (TIME-OUT always)

Similar to ticket #4867 and #4903, this sample contains no encoder string though.
