scripting massive number of files with ffmpeg [closed]
2 décembre 2020, par 8LiterAlright, I've got over 5000 MP4 files in a single directory that I would ultimately like to process using ffmpeg. I've got a few different solutions that all work by themselves, but put together do not make my job any easier.
The current file list looks like this, in one single directory :


- 

- 10-1.mp4
- 10-2.mp4
- 10123-1.mp4
- 10123-2.mp4
- 10123-3.mp4
- 10123-4.mp4
- 10123-5.mp4
- 10123-6.mp4
- 102-1.mp4
- 103-1.mp4
- 103-2.mp4
- 103-3.mp4
- 107-1.mp4
- 107-2.mp4
- 107-3.mp4
- 107-4.mp4
- 107-5.mp4
- 107-6.mp4
- 11-1.mp4
- 11-2.mp4










































The ideal process I would like is the following :


A. Take however many files in the directory have a particular prefix, for example the two "11" files at the bottom, and concatenate them into a single MP4 file. The end result is a single "11.MP4"


B. Delete the original two "11-1.mp4" and "11-2.mp4", keeping only the new "11.mp4" complete file.


C. Repeat steps A-B for all other files in this directory


This is not apparently possible right now from what I can glean from other threads, but I've tested a more manual approach which is not clean OR fast, and this is what my workflow looks like in real life...


- 

- move files with same prefix into new folder (I have a working bat file that will do this for me)
- run a ffmpeg bat file to process an "output.mp4" file (I have a working bat file that will do this for me)
- delete the original files
- rename the output.mp4 file to the prefix name (i.e. 11.mp4)
- copy that file back into the new directory
- repeat steps 1-5 a thousand times.














I've also looked into creating all new directories BASED on the filename (I have a working bat file that will do this for me) and then copy my ffmpeg bat file into each directory, and run each bat file manually... but again it's a ton of work.


(FROM STEP 1 ABOVE)


@echo off
setlocal

set "basename=."
for /F "tokens=1* delims=.*" %%a in ('dir /B /A-D ^| sort /R') do (
 set "filename=%%a"
 setlocal EnableDelayedExpansion
 for /F "delims=" %%c in ("!basename!") do if "!filename:%%c=!" equ "!filename!" (
 set "basename=!filename!"
 md "!basename!"
 )
 move "!filename!.%%b" "!basename!"
 for /F "delims=" %%c in ("!basename!") do (
 endlocal
 set "basename=%%c

 )
)


(FROM STEP 2 ABOVE)


:: Create File List
del "F:\videos\*.txt" /s /f /q
for %%i in (*.mp4) do echo file '%%i'>> mylist.txt

:: Concatenate Files
ffmpeg.exe -f concat -safe 0 -i mylist.txt -c copy output.mp4


Any ideas how I can approach this ? I'm open to powershell, batch, even python if I need to.

FFMPEG on AWS Lambda works selectively
20 novembre 2020, par Arindam BaralI am using FFMpeg on AWS Lambda to convert mp4 files to m3u8 format.


Here's my code :


ENCODE_SIZE = {
 '360p': ('360:640', '1000000'),
 '540p': ('540:960', '2000000'),
 '720p': ('720:1280', '5000000')
}
@app.route('/encode', methods=['GET'])
@token_required
def encodeVideo(current_user):
 try:
 userEmail = current_user.emailID
 
 courseID = request.args.get('courseID')
 fileKey = request.args.get('fileKey')
 print ('Input file key received ', fileKey)
 convType = 'all'
 if 'convType' in request.args:
 convType = request.args.get('convType')
 print ('Conv Type::::', convType)
 instiID = Course.query.filter_by(id=courseID).first().instiID
 adminEmail = Institute.query.filter_by(id=instiID).first().adminEmail
 if adminEmail != userEmail:
 return jsonify({'message': 'Not authorized'}), 403
 
 bucket = app.config['S3_CONTENT_FOLDER']
 folder = '/'.join(fileKey.split('/')[:-1])
 
 os.system('cp /var/task/ffmpeg /tmp/; chmod 755 /tmp/ffmpeg;')
 FFMPEG_STATIC = '/tmp/ffmpeg' #"/opt/bin/ffmpeg" # 
 # FFMPEG_STATIC = 'ffmpeg' #"/opt/bin/ffmpeg" # 
 
 preSignURL = getPreSignedS3URL(fileKey, bucket)
 print (preSignURL)
 
 outputFlag = []
 
 # outFileName = 'final_out.m3u8'
 outFileName = '/tmp/final_out.m3u8'
 with open(outFileName, 'a') as outFile:
 outFile.write('#EXTM3U\n')
 
 if convType == 'all':
 for ver in ENCODE_SIZE:
 print ('Starting for ver ', ver)
 outFileNameM3 = '/tmp/%s_out.m3u8' %(ver) 
 # outFileNameM3 = '%s_out.m3u8' %(ver) 
 
 subprocess.call([FFMPEG_STATIC, '-i', preSignURL, '-c:a', 'aac', '-c:v', 'libx264', '-s', ENCODE_SIZE[ver][0], '-f', 'hls', '-hls_list_size', '0', '-hls_time', '10', outFileNameM3])
 
 outFile.write('#EXT-X-STREAM-INF:PROGRAM-ID=1, BANDWIDTH=%s %s\n' %(
 ENCODE_SIZE[ver][1], outFileName
 ))
 # ret = os.system(commandStr)
 # outputFlag.append(ret)
 print ('Encoding completed for ver ', ver)
 else:
 ver = convType
 outFileNameM3 = '/tmp/%s_out.m3u8' %(ver) 
 # outFileNameM3 = '%s_out.m3u8' %(ver) 

 subprocess.call([FFMPEG_STATIC, '-i', preSignURL, '-c:a', 'aac', '-c:v', 'libx264', '-s', ENCODE_SIZE[ver][0], '-f', 'hls', '-hls_list_size', '0', '-hls_time', '10', outFileNameM3]) 
 
 outFile.write('#EXT-X-STREAM-INF:PROGRAM-ID=1, BANDWIDTH=%s %s\n' %(

 ))
 # ret = os.system(commandStr)
 # outputFlag.append(ret)
 outFile.close()
 print ('File Key Generated')
 #Upload files to s3

 print (streamFiles)
 for fl in streamFiles:
 finFileName = fl.split('/')[-1]

 # m3u8Files = glob.glob('/tmp/*.m3u8')
 # print (m3u8Files)
 # for fl in m3u8Files:
 # finFileName = fl.split('/')[-1]

 # for f in files:
 # os.remove(f)
 return jsonify({'message': 'Completed file encoding'}), 201
 except:
 print (traceback.format_exc())
 return jsonify({'message': 'Error in encoding file'}), 504
if __name__ == '__main__':
 app.run(debug=True,host="0.0.0.0", port=5000)



When I request for "540p", the m3u8 file gets converted perfectly.
However, when I request for "360p" and "720p", I see only the first 1 second of the video.


Please note - All the tls files are generated in all the cases. The problem is only in creation of the m3u8 playlist file.


Can someone please help in this regard ?


EDIT 1 : I am quite new to FFMPEG. So any help here will be very welcome

couldn't populate thumbnail on client side
8 novembre 2020, par Lokirouter.post("/thumbnail",(req,res)=>{

 let thumbsFilePath="";
 let fileDuration="";



 ffmpeg.ffprobe(req.body.filePath, function(err,metadata){
 console.dir(metadata);
 console.log('METADATA==>'+metadata);
 console.log(metadata.format.duration);

 fileDuration=metadata.format.duration;

 })

 
 ffmpeg(req.body.filePath)
 .on('filenames', function(filenames) {
 console.log('Will generate ' + filenames.join(','))
 thumbsFilePath="uploads/thumbnails/"+ filenames[0];
 })
 .on('end', function() {
 console.log('Screenshots taken');
 console.log('FILEPATH===>'+thumbsFilePath);

 // Will take screens at 20%, 40%, 60% and 80% of the video
 count: 3,
 folder: 'uploads/thumbnails/',
 size:'320x240',
 // %b input basename ( filename w/o extension )
 filename:'thumbnail-%b.png'
 });
})


the screenshots are saved perfectly and their path is also received to the client-side from
thumbsFilePathbut I cant populate it in the client-side page(react).. idk what I am doing wrong here.

here is client-side code. I used
usestate

const [FilePath, setFilePath]= useState('');
 const [Duration, setDuration] = useState('');
 const [Thumbnail, setThumbnail] = useState('');


here is an error when I try to populate img




const onDrop=(files)=>{
 let formData= new FormData();
