• Is there any way to provide different video qualities in my web application without converting each video to each format ?

  15 octobre 2019, par Dheeraj Arora

  i am building a web application which will handle thousand of videos. Currently, I am using ffmpeg to convert each video to 4 formats(1080,720,480,340px). It consumes lot of memory and time to upload for each video. Is there any best way that allows user to stream my videos in different video quality without converting each video ?

• Receiving and Manipulating RTSP stream using FFMPEG library in Java Application

  14 janvier 2015, par Bilal Ahmed Yaseen

  Hope you all be fine and doing great.

  I am currently working on a Java Web Application. I am getting Streaming video using RTSP URL. This URL is like :

   rtsp://---.---.---./6ca714ae28e52f31

  I have been able to capture video, diplay/listen it and store it in .mp4 file using FFMPEG with the following command :

  fmpeg -i rtsp://username:password@---.---.---.---/6ca714ae28e52f31 -f mov e:/bay.mov (with authentication)

  Now, I want to achieve the same in my Java application using ffmped library. I am sure if all this possible through commands then It will also be possible using its library. But unfortunately couldn’t get any working useful material regarding this on web.

  So, I simply want to ask that :

  1.  How can I fetch Streams using this RTSP URL in my Java Application with FFMPEG library
  
  2.  How can I Manipulate this fetched streaming such as start, stop, end etc.
  
  3.  How can I store this streaming in media file in playable form in any specified format.

  I have found a FFMPEG’s Java Rapper JJMPEG. Now I have two options either to issue FFMPEG command to CMD using Java Application or use JJMPEG library directly. Don’t know which one will be better choice.

  Thanks for your time and considerations.

• Trouble linking own application using ffmpeg/libav

  2 mai 2019, par Kiamur

  I have a source, that I’d like to build and link against the libav library on Linux.
  I followed the compilation guide of ffmpeg here : https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
  Everything works.
  I build the included examples like this : FFmpeg : building example C codes
  It also works.

  Now, I’d like to build my own little applications, where I try to learn about using libav. My current problem is, that by using the command line

  gcc muxing.c -g -I ../../../ffmpeg_build/include/ -L ../../../ffmpeg_build/lib/ -lavdevice -lavformat -lavfilter -lavcodec -lswresample -lswscale -lavutil -lm -lz -lpthread -lfdk-aac -lmp3lame -lx264 -lva -lX11

  I get to this point :

  muxing.c: In function ‘write_audio_frame’:

  Then I read, in order to overcome this linker error, I have to append -ldl to my command line, but then I get this :
