FFMPEG live transcoder aac_latm audio crash
15 mars 2013, par user1716057i am trying to use ffmpeg as a live transcoder to transcode tv channels from udp input to rtmp output to a wowza server.
i have 2 kinds of input channels in 1st kind the input audio is mp2 and in the second kind the input audio is acc_latm.
my problem is when i transcode the mp2 channels everything is fine but when i try to transcode the aac channel the audio is muted after few hours. but the video is fine.
the output codecs are : libx264 for video and faac or fdk-aac for audio output
i tried both aac encoders but it did not change.i think it is the ffmpeg aac decoder's problem. but i cannot fix this.
i need a way to detect the problem online and restart the ffmpeg. or change the ffmpeg decoder codec.
please help.
thanks. -

ffmpeg convert one png to DNxHD
15 mars 2019, par bcvery1I’m trying to create a DNxHD file from one PNG file. The output should be "24000/1001" fps, 1920x1080, using the dnxhd codec. Every frame should be the same. The outputted stream must be 20 seconds in length.
I have a solution which uses
filter_complex
to loop the PNG for each frame, however this results in extremely large files. Given that I will be combining possibly multiple hundred DNxHD files into one AAF file, the output file size is too large.Is there any improvement I can make on the command below which would achieve this file size reduction ?
ffmpeg -i INFILE.png -y -nostdin -an -vcodec dnxhd -pix_fmt yuv422p -vb 36M -framerate 24000/1001 -filter_complex loop=479:1:0 OUFILE.dnxhd
I do not know ffmpeg all that well, this command has been constructed by copying parts of commands I have found online.
