  • ffmpeg segmentation with multiple mp4 files to HLS stream

    15 juillet 2015, par Endre Börcsök

    I’m trying to segment multiple mp4 files from a .txt as concatenate works, but it doesn’t seem to work.

    I have concat.txt with the desired format :

    file video1.mp4
    
file video2.mp4
    
file video3.mp4

    etc...

    and my ffmpeg commands are :

    ffmpeg -i concat.txt -map 0 -codec:v libx264 -codec:a libfaac -f ssegment \
    
-segment_list playlist.m3u8 -segment_list_flags +live -segment_time 10 out%03d.ts

    Unfortunately every mediaplayer drops an error on playback.

    I presume that I can’t use this method to get done as concatenating. Do I have to concat all the mp4s into a single mp4, and segment that mp4 to a final m3u8 ? Or, can I segment the mp4s one by one and concat the .ts files to get better quality ?

  • ffmepg with multiple transcodings

    18 mars 2015, par mikael karlsson

    I am trying to send from one stream into ffmpeg to transcode the signal in to three different format´s in to a single .m3u8 file that will handle all the information about all the ts files.

    This is what i have make and that works but it not created all necessary information into the m3u8 file, so our jwplayer can´t chose quality from 720 480 280. It just created two different .ts files.

    ffmpeg -i http://inputserverip/ffmpeg/livestream/playlist.m3u8 -threads 4 -strict experimental -ar 44100 -vcodec libx264 -acodec aac -flags - global_header -f segment -segment_time 4 -segment_list_size 0 -segment_list testlist.m3u8 -segment_format mpegts stream_720%05d.ts -ar 44100 -strict experimental -vcodec libx264 -acodec aac -b:v 1000k -s 854x720 -flags - global_header -f segment -segment_time 4 -segment_list_size 0 -segment_list testlist2.m3u8 -segment_format mpegts stream_480%05d.ts

    Thanks

  • Live streaming HLS via ffmpeg, How to force client to start playing from the beginning ? From 1st segment

    12 mars 2015, par vedeojunky

    Is there a way, maybe via an ffmpeg option or flag, to force the client player to always start the playlist from the beginning when live streaming rather than the real time mid-stream ?

    Say the user comes in 1mn after the stream has started, rather than starting to watch at 1mn the player would start at the beginning of the video so minute zero.

    Here is my ffmpeg command :

    ffmpeg -f "screen capture" -s 1280x720 -r 30 -i :0.0+nomouse -f alsa -ac 2 -i pulse -async 30 -vcodec libx264 -pix_fmt yuv420p -acodec libfdk_aac -ar 44100 -b:a 64k -threads 0 -s 640x360 -f hls -g 1 -hls_time 1 -hls_list_size 1 -hls_allow_cache 0 /hls/#{@stream_name}/index.m3u8

    Thanks !
