• VLC Ubuntu : Problems converting rstp streaming into http streaming

  16 janvier 2019, par Gorka Sanz Monllor

  I am trying to convert in a Linux Ubuntu Machine a rstp stream into a http stream, so I execute the following comand :

  vlc -vvv -Idummy rtsp://**************************************transportmode=unicast --sout #transcode{vcodec=MJPG,venc=ffmpeg{strict=1}}:standard{access=http{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:8080/} --run-time= 300 

  vlc ://quit

  and it doesn’t work. The output is the following :

  root@f139da580fd9:/# vlc -vvv -Idummy rtsp://*********Streaming/Channels/101?transportmode=unicast --sout #transcode{vcodec=MJPG,venc=ffmpeg{strict=1}}:standard{access=ht                  tp{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:8080/} --run-time= 300 vlc://quit

• php - convert avi to mp4, webm and flv using ffmpeg command

  5 juin 2015, par Aisha

  My problem is I am trying to convert and upload videos into three formats at upload button. I am stuck at the very first step when i am trying to convert avi to mp4, webm and flv. I have tried various commands to convert in to mp4 and webm but nothing worked. its converting to flv smoothly. i searched a lot on internet but none of the commands worked. i have set execution_time to 0 and set_time_limit(0) as well for unlimited execution time. here are the commands i tried to convert in to mp4 and webm

  **For mp4:**
  
  
  
  exec("ffmpeg -i input.avi -c:v libx264 -crf 19 output.mp4");
  
  exec("ffmpeg -i input.avi -c:v libx264 -pix_fmt yuv420p output.mp4");
  
  exec("ffmpeg -i input.avi -c:v libx264 -c:a libfaac \ -movflags +faststart output.mp4");
  
  
  
  **For webm** 
  
  passthru("ffmpeg -i input.avi output.webm");
  
  passthru("ffmpeg -i input.avi -b 1500k -vcodec libvpx -acodec libvorbis -ab 160000 -f webm -g 30 output.webm");

  Note :
  For avi to mp4 files that are less than 1mb are converting successfully but more than 1mb files are showing its converting but its size is 0bytes.

  Similarly, i am facing a problem in converting mp4 to flv. Some files are converting and some are not. Some of the large files are converting but some small files are not converting. It was strange. there was no problem of permission or php configuration settings all was fine. I tried renaming a file which was not converting and it got uploaded. I am confused why this happened.

  Any help for both the issues is highly appreciated.

  Thanks in advance.

• Videos written with moviepy on amazon aws S3 are empty

  10 avril 2019, par cellistigs

  I am working on processing a dataset of large videos ( 100 GB) for a collaborative project. To make it easier to share data and results, I am keeping all videos remotely on an amazon S3 bucket, and processing it by mounting the bucket on an EC2 instance.

  One of the processing steps I am trying to do involves cropping the videos, and rewriting them into smaller segments. I am doing this with moviepy, splitting the video with the subclip method and calling :

  subclip.write_videofile("PathtoS3Bucket"+VideoName.split('.')[0]+'part' +str(segment)+ '.mp4',codec = 'mpeg4',bitrate = "1500k",threads = 2)

  I found that when the videos are too large (parameters set as above) calls to this function will sometimes generate empty files in my S3 bucket ( 10% of the time). Does anyone have insight into features of moviepy/ffmpeg/S3 that would lead to this ?
