[FFmpeg-user] preset files

[Scott Johnson]

Hi Everyone,

 

Here is a newbie question.

 

I have a C++ API that uses FFmpeg to stream an IP camera to my application.
I can not pass any variables to the background call to FFmpeg, other than
the source rtsp and transport type call.

 

Here is the command I used to test the FFmpeg settings to make it work with
my camera. Or should I say, here is the command I had to build to get it to
work.

 

ffmpeg -rtsp_transport tcp -i "rtsp://192.168.90.112:554/profile2/" -c:v
copy -c:a aac -max_muxing_queue_size 99999 -map 0 foo.mp4

 

I now need to take some of the parts and put them in a preset file. Because
FFmpeg does not like my pcm_alaw audio codex. I had to use "-c:a aac" to
replace the audio steam with a blank one. I also had to add the
"-max_muxing_queue_size 99999" to prevent buffer issues.

 

My video is using the h.264 codex. Do I just need to make a file named
h264.ffpreset, with the following lines:

 

               c:a=aac

               max_muxing_queue_size=99999

 

 

Thanks,

 

Scotty.
