Re: [FFmpeg-user] RTSP to HLS
Hello again,
maybe someone could help a ffmpeg-newbie to get the correct hls-settings
(hope there is something possible without re-encoding). The GOP is
IPP 31 CLOSED (got it from this script
https://gist.github.com/ragnraok/638023456771dc596e6f953b47061f0e).
Thanks,
Thomas

Hello,
I try to local restream https://herberts.meinekameras.de:10169
(rtsp-over-websocket) with this workflow: Go-script (proxy websocket to
rtsp) -> ffmpeg (rtsp to hls) -> xupnpd2 mediaserver -> vlc or TV.
It works good in vlc, but on the TV it plays too fast and there are
pauses. I tested all 4 hls-handlers (hls, hls2, hls3, hls4) in xupnpd2
with the same result.
ffmpeg command:
ffmpeg -re -rtsp_transport tcp -i
"rtsp://localhost:8554/axis-media/media.amp?overview=0=1=1280x720=empty=true=15"
-c copy -f hls /home/user/lighttpd-install/htdocs/stream.m3u8
Hope that someone could test the workflow and maybe optimize the
ffmpeg-command.
Thanks,
Thomas
PS: I never had this issue in xupnpd2 when receiving hls-streams
directly from the internet.

[FFmpeg-user] aresample filter position
Hi you lovely people, I have an error caused when I use the aresample filter that I think has something to do with the position of the filter in the chain. Failed to inject frame into filter network: I/O error The system takes a variety of different source configurations so I have some code that tries to manipulate the audio tracks and channels to fill the output. This can mean straight up pass through, or splitting channels, copying them and then merging. It all depends on the input config and output config. Anyhoo, some of the files that get encoded have audio that slowly drifts out of sync (possibly due to the supplied source). I wanted to add aresample=sync=1 to see if this resolves the issue. It was easiest for me to add this filter to the start of the audio filter chain. In most cases this does not cause any errors regardless of what manipulation is required afterwards, but in the instance below it is causing an IO error. In this instance, I see that the console output says Consider inserting the (a)format filter near their input or output If I move the aresample after the amerge it is processed successfully. As far as I can tell, the only time I get the Failed to inject frame into filter network: I/O error when the last filter is amerge. Do you know what the rules are for the position of this filter in the chain?

Because this is a generic script not limited to 1080p. That way I can use it for 4k as well what is not possible with level 4.2. Furthermore, with x11grab you get raw-image input what is remarkably big at 4k. But actually I don't really care about the size as long it's sufficiently large. Cheers, Stephan Am Di., 17.

[FFmpeg-user] ffmpeg: slide show on Windows
Hello there I'm on Windows 10 with ffmpeg and I would like to make a video (a slide) with a bunch of jpeg files and an mp3 music file. I tried first cat *.JPG | ffmpeg -y -f image2pipe -framerate 1 -i SligoAir_WhiteBlanket.mp3 -vsync vfr -pix_fmt yuv420p -movflags +faststart output.mkv with fails with cat: write error: No space left on device Then I tried with ffmpeg -y -f image2 -framerate 8 -i "%02d.JPG" -i SligoAir_WhiteBlanket.mp3 -vsync vfr -pix_fmt yuv420p output.mkv It fails also with Could find no file with path 'ffmpeg_run.bat2d.JPG' and index in the range 0-4 ffmpeg_run.bat2d.JPG: No such file or directory (ffmpeg_run.bat being my batch file to run ffmpeg). I did have some success with using ffmpeg -y -f concat -i liste.txt -i SligoAir_WhiteBlanket.mp3 -vsync vfr -movflags +faststart -pix_fmt yuv420p output.mkv liste.txt being the list of my jpeg files. Now I see that double-cliking on the output file sometime work and sometime not: the player "Films & TV" on my pc return almost immediately and sometime the video is played correctly. The VLC player does not show any image and the Windows media player shows the image but without sound... Can I change my command above to have a mkv file that is played correctly on all three type of players ? Can the cat command or the sequence pattern argument be used on windows ?

Re: [FFmpeg-user] How i can use vulkan hw accel and vulkan filters for streaming my desktop. Is KMS grab working with audio recording?
I don't have vulkan here but that's what I use with QSV. Maybe it is
an inspiration to you:
ffmpeg -video_size "$resolution"\
¦ ¦ -loglevel warning \
¦ ¦ -probesize 100M \
¦ ¦ -framerate 25 \
¦ ¦ -thread_queue_size 1024 \
¦ ¦ -init_hw_device qsv=hw -filter_hw_device hw \

¦ ¦ -f pulse -i "${audio_input}"\

¦ ¦ -b:a 128k\
¦ ¦ -vf
"format=yuv420p,hwupload=extra_hw_frames=64,format=qsv,vpp_qsv=detail=50:framerate=25,scale_qsv=w=-1:h=720:mode=2:extra_hw_frames=64"
\
¦ ¦ -global_quality:v 30 \
¦ ¦ -look_ahead 1 \

¦ ¦ -level:v 5.1\
¦ ¦ -preset veryslow\
¦ ¦ -bf 16 \
¦ ¦ -trellis 2 \
¦ ¦ -f flv \
¦ ¦ rtmp://url
Where resolution is in the format e.g. 1920x1080; xpos, ypos are
integers -- possibly zero, if you take the complete screen.
Cheers,
Stephan
