• FFMPEG - Invalid data found when processing input

  14 janvier 2016, par Siva Prasanna

  I want to play an RTSP live stream that I get internally. I’m using ffplay to play this. And this is the command that I use :
  ffplay -i "rtsp://test.vibrtech.com/mov/video.sav?MAC=00C2100F124&channel=2&GUID=betauser", but when I execute, I get Invalid data found when processing input error. The complete error output is given below :

  D:\..>ffplay -i "rtsp://test.vibrtech.com/mov/video.sav?MAC=00C2100F124&channel=2&GUID=betauser"

• Play stream via FFplay (FFmpeg) in Docker

  18 mars 2020, par Matan Marciano

  It is possible to play a video file via ffplay in Docker ?
  I have tried to build this docker :

  Dockerfile :

  FROM ubuntu:18.04
  
  RUN apt-get update && apt-get install -y ffmpeg

  After run this docker with a command :

  docker run -v /demo:/demo ffmpeg-test bash -c "ffplay -i /demo/test.mp4"

  I got ffplay logs without any player window.
  What am I missing ?

• linking against SDL library on ubuntu

  18 novembre 2013, par ali129

  this is my first post
  I have this problem with SDL library and "ffmpeg's ffplay" and "dosbox" on ubuntu. Here is what happenning :
  I have installed SDL and code::blocks.
  I also wrote a simple sdl program that shows a picture and tried to compile it tree ways :

  1- On command prompt which compiled and works perfectly. ( i mean : gcc -o hellosdl hellosd.c -lsdlmain -lsdl)

  2- On code::blocks by choosing file->new->project->SDL project
  which compiled but gives an error regarding i can't initialize graphic

  and finally
  3- On code::blocks but this time i manually configured sdl. i mean i simply choosed a blanked c file.then added sdl linker options "-lsdlmain and -lsdl" in code::blocks linker settings. and this time the program workes perfectly.

  Now the problem i have with dosbox and ffmpeg. I tried to compile these programs by running ./configure and make and they compiled without any error. but when i try to run dosbox or ffplay they give me these errors :

  ffplay error :

  libswresample 0. 15.100 / 0. 15.100
  Could not initialize SDL - No available video device
  (Did you set the DISPLAY variable ?)

  and yes my DISPLAY variable is set correctly

  echo $DISPLAY
  :0.0

  and

  dosbox error :

  ---

  Exit to error : Can't init SDL No available video device

  i also tried installing dosbox using sudo apt-get install dosbox and it works perfectly.

  i don't know why for some occasion my sdl library works and for some doesn't .
  it would be great if you could help me.
