transport stream over ip generated by ffmpeg is not detected by DVB Receiver.Receiver status is PCR not detected.I am using the following command

When I run the command below, only the 1280x720 line works. The other two lines do not work. Where am I missing?
ffmpeg -i test.mp4 -s:v:0 1280x720 -c:a aac -c:v:0 libx264 -b:v:0 2000k \
-s:v:1 640x480 -c:a aac -c:v:1 libx264 -b:v:1 1000k \

You need to map the input video stream for each output video stream explicitly like this:
ffmpeg -i test.mp4 \
-map 0:v:0 -s:v:0 1280x720 -c:v:0 libx264 -b:v:0 2000k \
-map 0:v:0 -s:v:1 640x480 -c:v:1 libx264 -b:v:1 1000k \
-map 0:v:0 -s:v:2 320x240 -c:v:2 libx264 -b:v:2 600k \
-c:a aac \
-f hls -hls_playlist_type vod -master_pl_name test.m3u8 \
-hls_segment_filename test_%v/test%06d.ts -use_localtime_mkdir 1 stream_%v.m3u8
I have successfully output 3 HLS output using -map 360, 720 & 1080p. My source file is 540p. once generated I use ffprobe on the newly created 360.ts, 720.ts, and 1080.ts and notice that there is a second video channel. This channel is the input video. How do I have FFmpeg not output the original video as part of the output?
this is the ffprobe on 360.ts

thank you.
1) -map 0 will include all original streams, including the video. Change to -map 0:a
2) You don't need to scale to 720p twice. scale once and split.
3) b:v and crf are exclusive in libx264 (h264 encoder). Pick one (crf is preferable)
Use

I've been banging my head for 2 days now. I can currently output 3 M3U8 "HLS" outputs resized but now I need to add an overlay to each output. The overlay image would need to be resized as well. My take on this is that the image should be applied to the source and then the 3 outputs can be generated. I have read that -vf cannot be used since there are 2 inputs. Here is what I am currently using which works.
How could I add an image overlay?
ffmpeg -hide_banner -y -i input.mov^
-vf scale=w=640:h=360:force_original_aspect_ratio=decrease -c:v h264 -profile:v main -crf 20 -sc_threshold 0 -g 72 -keyint_min 72 -hls_time 4 -hls_playlist_type vod -b:v 800k -maxrate 856k -bufsize 1200k -b:a 96k -hls_flags single_file^

Any advice would be greatly appreciated.
Thanks in advance.
You need to use a filter_complex for the overlay filter, and then splitting the result into 3 and scaling each copy:
ffmpeg -hide_banner -y -i input.mov -i image.png
-filter_complex "[0][1]overlay,split=3[a][b][c];[a]scale=w=640:h=360:force_original_aspect_ratio=decrease[a];[b]scale=w=1280:h=720:force_original_aspect_ratio=decrease[b];[c]scale=w=1920:h=1080:force_original_aspect_ratio=decrease[c]"
-map "[a]" -map 0:a -c:v h264 -profile:v main -crf 20 -sc_threshold 0 -g 72 -keyint_min 72 -hls_time 4 -hls_playlist_type vod -b:v 800k -maxrate 856k -bufsize 1200k -b:a 96k -hls_flags single_file 360p.m3u8
-map "[b]" -map 0:a -c:a aac -ar 48000 -c:v h264 -profile:v main -crf 20 -sc_threshold 0 -g 72 -keyint_min 72 -hls_time 4 -hls_playlist_type vod -b:v 2800k -maxrate 2996k -bufsize 4200k -b:a 128k -hls_flags single_file 720p.m3u8
-map "[c]" -map 0:a -c:a aac -ar 48000 -c:v h264 -profile:v main -crf 20 -sc_threshold 0 -g 72 -keyint_min 72 -hls_time 4 -hls_playlist_type vod -b:v 5000k -maxrate 5350k -bufsize 7500k -b:a 192k -hls_flags single_file 1080p.m3u8
(If your h264 encoder is x264, b:v has no effect when used with crf, but maxrate and bufsize do.)
Output should be:
- 2,5 Mbit/s CBR H.264/mpeg4
- Audio 128kbit/s joint stereo mpeg2
Command i am using as last looks like this, and stream is not CBR.

Try

-vf "hqdn3d" -me_method hex -sc_threshold 45 -refs 4 -flags +ilme+ildct+loop+mv4+cgop -g 100

-threads 0 -v 0
-f mpegts -muxrate 2500k "udp://#xxx.xxx.x.x:xxxx?buffer_size=100k&pkt_size=1316"
Added nal-hrd=cbr to x264opts and removed 8x8dct which is used in High profile.
If your input is interlaced, deinterlace it (add yadif filter).
I am trying to apply a watermark and also to scale it to the current video size via ffmpeg command:
Here is my inital comand that works without watermark
ffmpeg -v 0 -vcodec h264_qsv -i 'udp://#some.ip:1234?fifo_size=1000000&overrun_nonfatal=1&buffer_size=1000000' -vf scale=iw:ih -profile baseline -acodec aac -ac 1 -ar 44100 -ab 64k -deinterlace -vcodec h264_qsv -bufsize 4000k -maxrate 3500k -preset veryfast -vb 2000k -f flv rtmp://127.0.0.1/app/720
Now I tried to add the picture as a watermark. There was a conflict while using with -vf scale=-1:ih*.5, in order to eliminate the problem I used -s 1280x720 to specify the resolution for the video stream, it worked but not properly.
ffmpeg -v 0 -vcodec h264_qsv -i 'udp://#some.ip:1234?fifo_size=1000000&overrun_nonfatal=1&buffer_size=1000000' -i logo.png -filter_complex "overlay=10:10" -s 1280x720 -profile baseline -acodec aac -ac 1 -ar 44100 -ab 64k -deinterlace -vcodec h264_qsv -bufsize 4000k -maxrate 3500k -preset veryfast -vb 2000k -f flv rtmp://some.ip/app/720
The problem:
How can I specify in the ffmpeg command the both sizes of video and logo(watermark) so they don't conflict with each other and they auto adjust like -vf scale=-1:ih*.5 dose.
Thank you!
The scale2ref filter allows one to a video/image stream with reference to the dimensions of another video or image stream
e.g.
ffmpeg -v 0 -vcodec h264_qsv -i 'udp://#some.ip:1234?fifo_size=1000000&overrun_nonfatal=1&buffer_size=1000000' \
-loop 1 -i logo.png \
-filter_complex "[1:v][0:v]scale2ref=iw/8:-1[logo][0v];[0v][logo]overlay=10:10[v]" \
-map "[v]" -map 0:a \
-profile baseline -acodec aac -ac 1 -ar 44100 -ab 64k \
-deinterlace -vcodec h264_qsv -bufsize 4000k -maxrate 3500k \
-preset veryfast -vb 2000k \
-f flv rtmp://some.ip/app/720
Here 1:v - the logo image - is being scaled to 1/8th the width of [0:v], the H.264 stream.
