FFMpeg Question about paket pts, dts and duration parameters
27 avril 2020, par Denis GottardelloAccording with the remuxing.c example I have using the flollowing 3 lines of code :



Packet.pts= av_rescale_q_rnd(Packet.pts, pAVStreamIn->time_base, pAVStreamOut->time_base, static_cast<avrounding>(AV_ROUND_NEAR_INF | AV_ROUND_PASS_MINMAX));
Packet.dts= av_rescale_q_rnd(Packet.dts, pAVStreamIn->time_base, pAVStreamOut->time_base, static_cast<avrounding>(AV_ROUND_NEAR_INF | AV_ROUND_PASS_MINMAX));
Packet.duration= av_rescale_q(Packet.duration, pAVStreamIn->time_base, pAVStreamOut->time_base);
</avrounding></avrounding>



The code works but not using an rtsp camera as source. I obtain an error at av_interleaved_write_frame function.
Please have a look at the following log report :



AudioIndex Packet.pts: 0, Packet.dts: 0, Packet.duration: 160
AudioIndex Packet.pts: 120, Packet.dts: 120, Packet.duration: 160 
AudioIndex Packet.pts: 312, Packet.dts: 312, Packet.duration: 160
AudioIndex Packet.pts: 432, Packet.dts: 432, Packet.duration: 160
AudioIndex Packet.pts: 632, Packet.dts: 632, Packet.duration: 160
AudioIndex Packet.pts: 752, Packet.dts: 752, Packet.duration: 160
AudioIndex Packet.pts: 952, Packet.dts: 952, Packet.duration: 160
AudioIndex Packet.pts: 1072, Packet.dts: 1072, Packet.duration: 160
AudioIndex Packet.pts: 1272, Packet.dts: 1272, Packet.duration: 160
AudioIndex Packet.pts: 1392, Packet.dts: 1392, Packet.duration: 160
AudioIndex Packet.pts: 1592, Packet.dts: 1592, Packet.duration: 160
AudioIndex Packet.pts: 1712, Packet.dts: 1712, Packet.duration: 160
VideoIndex Packet.pts: 9223372036854775808, Packet.dts: 9223372036854775808, Packet.duration: 0




As you can see the pts, dts, duration parameters relative to audio stream is ok, the video parameters abolutally not.
How can I do to rewrite the video parameters ?
Can anyone explain ?

FFMPEG reduce dynamic range (VLC port question)
14 mars 2020, par H3rdellIs there a way to do the exactly same thing as the image below (VLC) but using FFMPEG ? I want it with FFMPEG to automate some jobs with batch files.
In VLC, alongside the settings in the above image, I also enable the Dynamic Range Compressor.
My settings for the compressor filter in VLC are :
- RMS/PEAK : 0
- ATTACK : 15ms
- RELEASE : 300ms
- THRESHOLD : -25dB
- COMPRESSION RATIO : 20.0 to 1
- KNEE RADIUS : 1.0dB
- MAKEUP GAIN : 15.0dB
Thanks in advance.

Which Platform/Language to choose for Video Management System [closed]
5 décembre 2019, par Vivek BuddhadevWe have started on a new project, Which enables for the multiple IP cameras(Around 1000 Cameras) to record as well as available for live streaming.
Like https://www.security.honeywell.com/uk/product-repository/maxpro-vms
Initially, we have tried using
ffmpeg
commands that saves data in chunks :ffmpeg -i {rtsp_url} -fflags flush_packets -max_delay 2 -flags -global_header \
-hls_time 2 -hls_list_size 3 -vcodec copy -y /var/www/html/Cam01.m3u8Then we have started http server and using node.js we are displaying the stream.
But as we are adding more cameras into it, the performance is going down.
Kindly suggest if there is any other way to achieve this functionality which help us to fulfill the above requirement.
