avcodec/hapdec : log reason for failure when texture type doesn’t match stream
21 juillet 2015, par Tom Butterworth -
Convert a file to match another's specification exactly with FFMPEG ?
25 mars 2022, par user1748217I have a series of files from the same source and so of the exact same format in every way that I'm concatenating with FFMPEG


- 

- file1.mov
- file2.mov
- file3.mov








This is very fast and is working fine however no I want to take optional intro file (from many different source and of many different types) and convert that to match the others before joining.


- 

- intro.mp4




How do I do this with FFMPEG ?


Does this give me everything I need ?


ffprobe -select_streams a:0 -show_entries \
 stream=codec_name,channels -of default=nw=1:nk=1 -v 0 ./file1.mov

ffprobe -select_streams v:0 -show_entries \
 stream=codec_name,width,height,r_frame_rate,pix_fmt \
 -of default=nw=1:nk=1 -v 0 ./file1.mov


So with that I can just :


ffmpeg -i intro.mp4 \ 
 -c:v h264 -s 1280x720 -pix_fmt yuv420p -framerate 30/1 \ 
 -c:a pcm_s16le -ca 1 intro.mov


and then merge it seamlessly to the rest ?


ffmpeg -f concat -safe 0 -i videos.txt -c copy merged.mov -y


The answer is of course "no", hence the request for your support.
The audio is fine when files 1, 2 & 3 are merged but is too fast when the intro + 1, 2 & 3 are merged. The converted intro file always plays fine on it's own after the conversion and after the merge, but the others play audio too fast after the merge.


What am I missing ?


UPDATE :


So in the end this worked for the intro :


ffmpeg -i intro.mp4 \ 
 -c:v h264 -s 1280x720 -pix_fmt yuv420p -framerate 30 \ 
 -c:a pcm_s16le -ac 1 -b:a 512k -ar 32000 intro.mov -y
