The fdk encoder has a latm option that you have to set to 1 to get latm output..

Re: [FFmpeg-user] AAC LATM Encoding
I've used this setup and it works well... # ffmpeg -i input -c:v libx264 -c:a libfdk_aac -flags:a +global_header -latm 1 -strict 2 -profile:a aac_he -mpegts_flags latm -f mpegts output Of course you need to set all the parameters you prefer related to video/audio bandwidth, bitrate and so on.

[FFmpeg-user] How to use ffmpeg to do a PC side of the player??
Dear Sir or Madam, I'm sorry to bother you and I am writing to ask you about ffmpeg several questions. My name is Peter Yang. I am from Chongqing, China. I am a graduate student of Chongqing University of Posts and Telecommunications. At present, I am doing research on h.265 / HEVC and ffmpeg. For the video stream encoded with h.265 / HEVC, I'm going to be a player that can decode the video stream in this encoding format. And it has fast forward, pause, play and other functions.So how do I use ffmpeg to do this one on the PC side? Do you have a relevant case? Can you give me a look? I hope you have not wasted your time too much. Thank you for your help and look forward to your reply. Best wishes, Yours, Peter Yang ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
[FFmpeg-user] Chroma problem converting mp4 to prores
Hi guys, I am having a issue where all the clips that I convert have a chroma problem. The red is saturated on all clips and there are red horizontal lines in the chroma. $ ffmpeg -y -i 5079162_NHL\ Marleau.mp4 -acodec pcm_s16le -vcodec prores_ks -profile:v 1 -copytb -1 -vf yadif=1 -qscale:v 10 mp4-yadif1-q10.mov I thought this might be the chroma bug but I have experimented with a couple of different options replacing yadif=1 with the following: -vf scale=out_color_matrix=bt709 -pix_fmt yuv422p10le -vf colormatrix=bt601:bt709 -vf yadif The yadif=1 option provides the closest results and specifying multiple options seems to make it worse not better. The problem is more obvious on a broadcast monitor. We are also having a problem where the converted clips are 1 frame shorter than the original, missing a black frame at the start of the clip.

[FFmpeg-user] Difference in ffmpeg command execution time
Hi, On trying to create video using ffmpeg as per command below, it takes much more time (around 6 minutes) on AWS lambda and EC2 instances where as it takes just 2 minutes on my local mac. I understand run time differs on CPU, but I am not able to figure out what needs to be done in order to get it run within 5 minutes on lambda. Or it could be due to differences in or missing libraries. Could someone please point me in right direction? Command: ffmpeg -safe 0 -f concat -i /tmp/config.txt -i /tmp/audio.mp3 -y -pix_fmt yuv444p -shortest /tmp/out_.mp4 Attached are the logs of both the machines. -- Thanks, Vivek ec2.log Description: Binary data local.log Description: Binary data ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
