want a batch convert ts to mp4. I have this code, it doesn't work

ejames82 · 12-03-2021, 03:01 PM

hi,

I am hoping to find something to run in the linux mint terminal that will convert all of the .ts files that it finds to .mp4 in a directory.
while searching google I found this:

------------------------------------------------------------------------
for %%f in (*.ts) do (
ffmpeg -i "%%f" -c:v h264_nvenc -c:a copy "%%f.mp4"
)

pause
------------------------------------------------------------------------

when I ran it in the terminal, I got this:

ed@ed-MS-7759 ~/Desktop/jsdtd $ for %%f in (*.ts) do (
bash: syntax error near unexpected token `('
ed@ed-MS-7759 ~/Desktop/jsdtd $ ffmpeg -i "%%f" -c:v h264_nvenc -c:a copy "%%f.mp4"

ed@ed-MS-7759 ~/Desktop/jsdtd $ pause

the questions I have:
what does the groupings of %%f (three instances) mean, individually?
do I need to substitute the first %%f with absolute path, in this case /home/ed/Desktop/jsdtd?
is there anything else wrong with the code?
do I need to make a .sh file to use this?
thanks

Code:

for %%f in (*.ts) do (
ffmpeg -i "%%f" -c:v h264_nvenc -c:a copy "%%f.mp4"
)

pause

This is a Windows/DOS batch file which does not work on linux. A quick conversion to bash...

Code:

for f in *.ts; do
  ffmpeg -i "$f" -c:v h264_nvenc -c:a copy "$(basename -- "$f" .ts).mp4"
done

hello michaelk,

there's probably something wrong on my end.
this is what happened:

ed@ed-MS-7759 ~/Desktop/jsdtd $ for f in *.ts; do
> ffmpeg -i "$f" -c:v h264_nvenc -c:a copy "$(basename -- "$f" .ts).mp4"
> done

I see this in the terminal output:

Cannot load libcuda.so.1

my google search suggests it's part of the cuda package, so I installed the latest libcuda

thanks for the reply michaelk, it was worth a shot. it made a file, the file just wouldn't play

michaelk · 12-03-2021, 06:18 PM

I have not played with ffmpeg in a long time try this on a single file.

ffmpeg -i input.ts -c:v libx264 -c:a copy output.mp4

I captured the terminal output that I considered relevant. it did work. nice job.

I would recommend something like this.

Code:

#Array of vids
vids=(file1.ts file2.ts file3.ts file4.ts)

#Loop through them
for v in "${vids[@]}"; do
    #Example: 24fps, 768x432 x264 vid, copy audio, into a mp4 container, same name as input
    ffmpeg -i "$v" -c:a copy -c:v libx264 -crf 18 -preset slow -maxrate 3000k -bufsize 1M -r 24 -s 768x432 ${v%.*}.mp4
done
