Concatenating video files with ffmpeg, no sound in output file [on hold]
1er septembre 2013, par JunaidI am concatenating different AVI video files. The input files has been specified in
input.txtin the order required. First video file does not have sound track, but subsequent files have.After completion the resulting the operation, the output does not have audio !
If I remove first video files from input then resulting video gets sound. So it means the output format follows the first item in input list. How can I solve this problem.
Please suggest the options in ffmpeg ; not in any other tools like mencoder.
ffmpeg -f concat -i inputs.txt -c copy test.avi

swscale/aarch64 : vscale optimization
13 août 2022, par Swinney, Jonathanswscale/aarch64 : vscale optimization
Use scalar times vector multiply accumlate instructions instead of
vector times vector to remove the need for replicating load instructions
which are slightly slower.On AWS c7g (Graviton 3, Neoverse V1) instances :

I am able to create m3u8 file using ffmpeg from rtmp live but not able to play the file in html5 video tag & apple device
3 janvier 2014, par NikitaI am able to create the m3u8 file by following steps :
1.Execute ffmpeg -v verbose -i rtmp://<host>:<port>/<stream> -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 400k -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 <pathtofolderyouwantto>/<streamname>.m3u8
</streamname></pathtofolderyouwantto></stream></port></host>2.Make that folder you just mentioned on ffmpeg command () to be accessible by an http url.
3.Create a simple html page to play :
<video controls="controls" width="480" height="270" src="<streamName>.m3u8"></video>
But not able to play using html5 video tag as well as in apple device.
