Cant we use mp4 as format of FFmpegFrameRecorder while RTMP streaming
13 avril 2016, par SatyI am trying to stream video with FFmpegFrameRecorder using javacv. All are working good however I want to use "mp4" as the recording format instead of FLV. is that possible because when i set that, it crashed ?

Squeeze image when images are larger image than 1024X768 in FFMpeg with javacv
14 avril 2016, par SatyI am using this below code to stream RTMP to my Adobe FMS Server... its doing good. It shows squeezed image if the camera resolution is above 1024X768.
The issue came when we tested on a Tab which has camera resolution of 1200X800, The recorder automatically takes the resolution of 1024X768 which makes the preview and the actual video a squeezed one and one more thing is recording format does not support MP4Can anyone describe why its not working with this and can we use that format.

How to fix "FFmpeg command cannot work when multiple mp3 file to process into one" on server side
9 février 2019, par Harshil DholakiyaI am using FFmpeg in my php yii2 project. FFmpeg working fine in my project but one major problem is execute FFmpeg command with multiple input file. When i try to use single file to process in ffmpeg command then it works. so, how can i fix this problem ? I am using hostGator shared plan for my project. Please, help if is there any process limit or file open limit on server that i don’t know.
I have tried using this command in php exec() :
ffmpeg -y -i /uploads/ac/10122018-09351115-a94rlvlawvikskb4vdrca.mp3 -i /uploads/ac/09012019-035928988-assknyrk8oujccwevir7.mp3 -f lavfi -i anullsrc -filter_complex "[2]atrim=duration=3[g0];[2]atrim=duration=1[g1];[2]atrim=duration=5[g2];[g0][0][g1][1][g2]concat=n=5:v=0:a=1" /uploads/jm/concat.mp3 2>&1Above command works local side but not working on server side.
output on server side with error code 1:
