[FFmpeg-user] NV12 devices/players compatibility
Hi All, I know this is not strictly related to FFMPEG but please don’t insult me I normally transcode using ffmpeg with h264_nvenc, that produces a NV12 output, then I convert it in pix_fmt yuv420p before chunking in HLS/DASH But this conversion, when I do “all in hardware” transcoding in multiple profiles forces me to create quite complex filters. So I’d like to simplify the filters and just use NV12 end to end. Does anybody know realisticly how many devices/players out there can actually play a NV12 stream?

Re: [FFmpeg-user] How to have a secure UDP BroadCast
I would go for SRT as well. It doesn't have a proper username/password method, but the passphrase mechanism implement should suffice. In addition to this it can also compensate a lot of network issues between transmitter and receiver that couldn't be compensated by UDP, and doesn't add a lot of latency like other authenticated protocols like RTMP or HLS.

A container format with support for timestamps such as mpegts (b). Capabilities similar to UDP Would be Haivision's SRT, which FFmpeg supports if enabled on build time via --enable-libsrt. SRT allows for optional encryption, whose details can be viewed via ffmpeg -h protocol=srt. Note that depending on your application requirements, you'll need to ensure that your receiver can handle SRT input, OR use FFmpeg to handle SRT TX and Rx in the network segment where such content security is desired.

Re: [FFmpeg-user] FFMPEG endlessly increases memory usage over time with HLS packaging.
Actually I have several machines in production (dual Xeon 5620 - 32GB - Nvidia P2000) that are running 14 ffmpeg process each, all decoding Full HD mpegts and transcoding them in 4 different profiles each (HD/SD/SDh/SDq) and to be honest they work like a sharm and are also very stable. Based on this experience I actually expected, just to repacketize pre-encoded content in HLS, to run at least 40/45 (even more) process per machine Let me go ahead with my experiments, I'll be more than happy to produce the results.

No. At least both your „free“ and „valgrind“ output indicate the opposite (as does the word „saturate“ above).

Hi All, I would like to use ffmpeg as live HLS ABR packager and use /dev/shm to store playlist and chunks in RAMDISK. But unfortunately I’ve noticed that ffmpeg constantly increase the memory used until it saturates it. the script does basically this steps: mkdir -p /dev/shm/live/test cd /dev/shm/live/test /usr/bin/ffmpeg -i udp://239.239.239.109:4000?fifo_size=100 -i udp:// 239.239.239.109:3000?fifo_size=100 -i udp:// 239.239.239.109:2000?fifo_size=100 -i udp:// 239.239.239.109:5000?fifo_size=100 -i udp:// 239.239.239.109:6000?fifo_size=100 -c copy -b:v:0 1400k -b:v:1 700k -b:v:2 300k -b:a:0 128k -b:a:1 64k -b:a:2 64k -b:v:3 2500k -b:v:4 3200k -b:a:3 128k -b:a:4 128k -map 0:v -map 0:a -map 1:v -map 1:a -map 2:v -map 2:a -map 3:v -map 3:a -map 4:v -map 4:a -f hls -master_pl_name index.m3u8 -var_stream_map v:0,a:0,name:SD v:1,a:1,name:SDh v:2,a:2,name:SDq v:3,a:3,name:HD v:4,a:4,name:FHD -hls_time 10 -hls_list_size 6 -hls_flags delete_segments -hls_segment_filename test-%v/chunk-%08d.ts test-%v/playlist.m3u8 Then, this is the result of the free command as soon I launch the script: totalusedfree shared buff/cache available Mem: 32924468 670052299912683788 226314831781984 Swap: 8388604 0 8388604 This is the same result after 4 minutes: totalusedfree shared buff/cache available Mem: 32924468 108980429504504 70348 233016031295808 Swap: 8388604 0 8388604 This is after 7 minutes: totalusedfree shared buff/cache available Mem: 32924468 122409629360344 78540 234002831153156 Swap: 8388604 0 8388604 This is after 10 minutes: totalusedfree shared buff/cache available Mem: 32924468 13384922925 64832 232708831052356 Swap: 8388604 0 8388604 Here after 14: totalusedfree shared buff/cache available Mem: 32924468 138988029211896 60160 232269231005696 Swap: 8388604 0 8388604 Here after 30: totalusedfree shared buff/cache available Mem: 32924468 151603628879424 111332 252900830825508 Swap: 8388604 0 8388604 Please bear in mind that as a matter of test, I’ve also tried to store the files in a SSD but the outcome was basically the same.

With some custom code it isn't hard to pass through SCTE-35 triggers, largely dependent on whether you are reusing the stream timing from the original incoming stream. If your output stream as the same timestamps as the incoming stream (i.e. using -copy_ts), then you can essentially just copy the packet to the output unmodified without having to parse the SCTE-35 payload. However if you're retiming the stream then you need to parse the packet, adjust the pts_offset field, and then create a new packet. And of course you need to modify the MPEG TS mux to adjust the PMT and create the table sections, since SCTE-35 is done through tables as opposed to through an elementary stream containing PES packets. I've got patches which do this but they aren't upstream. Devin -- Devin J.

[FFmpeg-user] HLS setting NAME in EXT-X-MEDIA
Hi Guys, Does anybody know If there is a way to set a specific value of NAME in EXT-X-MEDIA with the HLS muxer? My command line is: /usr/src/ffmpeg-4.2.2/ffmpeg -hwaccel cuvid -c:v h264_cuvid -i INPUT.ts \ -filter_complex "[0]split=5[inter-SD][inter-SDh][inter-FHD][inter-HD][inter-SDq];[inter-SD]hwupload,scale_npp=640:480:format=yuv420p,hwdownload[vout-SD];[inter-SDh]hwupload,scale_npp=480:320:format=yuv420p,hwdownload[vout-SDh];[inter-FHD]hwupload,scale_npp=1920:1080:format=yuv420p,hwdownload[vout-FHD];[inter-HD]hwupload,scale_npp=1280:720:format=yuv420p,hwdownload[vout-HD];[inter-SDq]hwupload,scale_npp=320:240:format=yuv420p,hwdownload[vout-SDq]" \ -c:v h264_nvenc -preset:v fast -g:v 50 -flags +cgop -c:a aac \ -map [vout-SD] -map [vout-SDh] -map [vout-FHD] -map [vout-HD] -map [vout-SDq] \ -b:v:0 800k \ -b:v:1 500k \ -b:v:2 2000k -profile:v:2 high -level:v:2 4.1 \ -b:v:3 1200k -profile:v:3 high -level:v:3 4.1 \ -b:v:4 300k \ -map 0:a:0 -map 0:a:0 -map 0:a:1 -map 0:a:1 \ -b:a:0 128k -b:a:1 64k -b:a:2 128k -b:a:3 64k \ -metadata:s:a:0 language=eng -metadata:s:a:1 language=eng \ -metadata:s:a:2 language=fre -metadata:s:a:3 language=fre \ -var_stream_map "a:0,agroup:HIGH_BR,language:ENG,name:audio_en_hi a:2,agroup:HIGH_BR,language:FRE,name:audio_fr_hi a:1,agroup:LOW_BR,language:ENG,name:audio_en_lo a:3,agroup:LOW_BR,language:FRE,name:audio_fr_lo v:0,agroup:LOW_BR,name:Video_SD v:1,agroup:LOW_BR,name:Video_SDh v:2,agroup:HIGH_BR,name:Video_FHD v:3,agroup:HIGH_BR,name:Video_HD v:4,agroup:LOW_BR,name:Video_SDq" \ -f hls -hls_playlist_type vod -hls_time 10 -hls_list_size 0 -hls_allow_cache 1 -master_pl_name master.m3u8 \ -hls_segment_filename alextest1/%v/chunk-%08d.ts alextest1/%v/playlist.m3u8 The comman more or less does what I need, but the NAME value is always set as "audio_1, audio_2" and so on. #EXTM3U #EXT-X-VERSION:3 #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="group_HIGH_BR",NAME="audio_0",DEFAULT=YES,LANGUAGE="ENG",URI="AEN128/playlist.m3u8" #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="group_HIGH_BR",NAME="audio_1",DEFAULT=NO,LANGUAGE="FRE",URI="AFR128/playlist.m3u8" #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="group_LOW_BR",NAME="audio_2",DEFAULT=NO,LANGUAGE="ENG",URI="AEN64/playlist.m3u8" #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="group_LOW_BR",NAME="audio_3",DEFAULT=NO,LANGUAGE="FRE",URI="AFR64/playlist.m3u8" #EXT-X-STREAM-INF:BANDWIDTH=950400,RESOLUTION=640x480,CODECS="avc1.4d401e,mp4a.40.2",AUDIO="group_LOW_BR" Video_SD/playlist.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=620400,RESOLUTION=480x320,CODECS="avc1.4d4015,mp4a.40.2",AUDIO="group_LOW_BR" Video_SDh/playlist.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=2340800,RESOLUTION=1920x1080,CODECS="avc1.640029,mp4a.40.2",AUDIO="group_HIGH_BR" Video_FHD/playlist.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=1460800,RESOLUTION=1280x720,CODECS="avc1.640029,mp4a.40.2",AUDIO="group_HIGH_BR" Video_HD/playlist.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=400400,RESOLUTION=320x240,CODECS="avc1.4d400d,mp4a.40.2",AUDIO="group_LOW_BR" Video_SDq/playlist.m3u8 I would like to be able to set the value with something else, eg. the language (NAME="English" or NAME="French") but I didn't find any information about that.
