Syntax error : "(" unexpected — with !(*.sh) in bash script [duplicate]
25 janvier 2023, par Jmv JmvI want to run a sh file :



#!/bin/bash
for f in !(*.sh); do
 ffmpeg -i "$f" -vf yadif=0:-1 -threads 0 -c:v libx264 -pix_fmt yuv420p \
 -r 29.97 -b:v 3000k -s 1280x720 -preset:v slow -profile:v Main \
 -level 3.1 -bf 2 -movflags faststart /mnt/media/out-mp4/"${f%.mxf}.mp4"

Any idea what might be happening ?

ffmpeg produces "is_avc" = false with h264_nvenc & tee muxer
14 août 2018, par Areeb111I am using ffmpeg for encoding MKV (Matroska Video files) to 2x MP4 (H264 - 720p Main@L4) & (H264 - 360p Baseline@L3.1).
Having really strange problem when using
-c:v h264_nvenc
andtee muxer
then the produced output file is havingis_avc=false
even i have checked the same input matroska file with another server running with Intel QuickSync-c:v h264_qsv
with the same command then the produced output file isis_avc=true
.The main goal that i want the
is_avc=true
is because the files must be played usingnginx-vod-module
which requires the AVC video format to be streamed.Steps to reproduce the problem :
- Custom ffmpeg build with NVENC support
ffmpeg version N-91182-gbdf1bbd Copyright (c) 2000-2018 the FFmpeg developers built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-28)
- ffprobe
version 4.0.2-static https://johnvansickle.com/ffmpeg/ Copyright (c) 2007-2018 the FFmpeg developers
- Running ffmpeg command line with NVENC and tee muxer
/root/ffmpeg -y -t 00:00:50 -i "testinput.mkv" -filter_complex "[0:v]split=2[s0][s1];[s0]scale=-2:720[v0];[s1]scale=-2:360[v1]" -map "[v0]" -map "[v1]" -map 0:a -c:v h264_nvenc -b:v:0 1100k -b:v:1 600k -profile:v:0 main -profile:v:1 baseline -level:v:0 4 -level:v:1 3.1 -ac 2 -c:a aac -b:a 128k -af "aresample=async=1000:first_pts=0" -f tee "[select=\'v:0,a\']testoutput.mp4|[select=\'v:1,a\']testoutput-360.mp4"
- Running ffprobe for the output file to check "is_avc" :
./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4
-
My current ffprobe output results are :
./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4
