the tutorial code was update to work on new ffmpeg versions.I’m using VM Ubuntu 16.0.4 64 bit fresh install on windows 10 host.

so why I’m having all of these errors ?

Update :
I moved to Ubuntu 12.04 VM and ffmpeg 0.11, I instilled it with opencv 2.4.2 here is the link . This should work yet i don’t why I’m having hard time compiling such small program.

Update2

I changged avcodec_free_frame to av_free and the file complied

Dranger code is old

Update 3
i downloaded ffmpeg 1.0.10 which has the same library version that is the tutorial tested on. Everything complied without any problem now.

Issue when streaming some TV channels threw ffMpeg

7 octobre 2016, par Raphael Serievic

I am trying to stream a TV Tuner feed with ffMpeg through udp.

The ffMpeg command line I use is the following :

ffmpeg.exe -i udp://@239.255.255.9:1234 -map 0:p:1317:0 -profile:v baseline -crf 30 -preset ultrafast -vcodec libx264 -r 25 -vf scale=720:576-b:v 500k -f rtp udp://10.150.112.107:15048/ -map 0:p:1317:1 -acodec pcm_mulaw -strict experimental -ar 8k -ac 1 -b:a 128k -f rtp udp://10.150.112.107:15032/

Where :

1317 is the program id (channel)
10.150.112.107 is where I want to stream the TV channel
239.255.255.9 is where I receive the original TV channel’s feed from my TV Tuner

My problem is that with some program IDs it is working and with some others it is not : it is working with 1572 ("channel 10 hd") but not with 1317 ("7flix Sydney").

The output of this command-line for channel 1572 (where it works) is the following :

C:\Program Files (x86)\Tuner Manager\ServerModule> ffmpeg.exe

 -i udp://@239.255.255.7:1234 -map 0:p:1572:0 -profile:v baseline -crf 30 -prese

How to combine 2 videos using either NReco ffmpeg ConvertMedia or just ffmpeg command line ?

11 octobre 2016, par M. Ilchuk

We have 2 videos : video1.webm and video2.webm.
How to combine these two and get output.mp4 which contains video from video1.webm and audio from video1 and video2 ?

Example :

video1(audio1 in video1) + video2(audio2 in video2) = outputVideo(video1 + audio1 +audio2)

image example

ffmpeg -i 1.webm -i 2.webm
