ok what i understand , if i try to change something ( resolution , sound ... ) it use cpu and it's bad ...

so :

sudo /usr/src/ffmpeg/ffmpeg -c:v h264_mmal -i http://192.168.0.28:...:EEEE0000:0:0:0: -c:v h264_omx -c:a copy -b:v 500k /home/pi/outputfile9.mp4

it's best result ( cpu 50 % max fps 22 )

BUT

i have randomly some error "PES packet size mismatch" with some cut ...

If i look on google , new version of ffmpeg worrect it ...

I must look more details , but i think i must compile again  ...

[Erik Slagter]

the topic was about encoder not decoder.

Also, ffmpeg doesn't have an interface to the STB encoding api, so as soon as you start using ffmpeg, it will all run on the cpu (software).

[martossien]

find and correct the error ....

It's my fault = Overclock to heavy

reduce to 1350 and gpu 550 and ... works perfect ...

 

For hd51 with only armv7 works with all channel not HD

If we want it in HD we must have hardware decoder and if possible hardware encoder.

 

For Raspberry i continue teh test and i want to test db transcoder for raspberry after .

[martossien]

One question :

 

The HD51 can make PiP at 576i , could we have this transcode ?

in this case the cpu is enough to transcode 576i to 320x240 ...

[betacentauri]

The drivers don't give us access to it. So answer is no.

[martossien]

I make new compil ( i want all the codec to make test and use last version )

i make some correction ...

[martossien]

Yes best result with this compile !

[martossien]

Ok now the server who receive the stream flux ... another unknow for me, so i check all the way to stream and i look for server : ( if i put xxx it's beacause i don't know ... )

 

RTMP
-f flv "rtmp://192.168.1.2/live/stream"

[martossien]

error with sound of dvb :

http://git.videolan....5884fe806a13a21

must compile again ....

[martossien]

Some news

https://www.raspberr...d7606e190f9e7da

So i install crtmpserver ( be carefull the soft is stopped and lot of trouble with conf file and log )

and i test it ...

 

Next point is install http://e2transcoder..../author/andris/

[martossien]

ok crtmpserver ok view stream ok:

 

Flux in enter : ( CHANNEL NRJ12 1080HD )

ffmpeg -threads 8 -c:v h264_mmal -i http://192.168.0.28:...:EEEE0000:0:0:0: -c:v h264_omx -c:a copy -c:a libmp3lame -ac 1 -f flv -metadata streamName=myStream tcp://0.0.0.0:6666

 

Flux read : (windows )

C:\ffmpeg\bin\ffplay -an "rtmp://192.168.0.19/flvplayback/myStream live=1"

 

for the moment i don't find with VLC ... if you have an idea ...

 

If you prefer you can make a web server with script to see the video on web page in your raspberry ( https://www.raspberr...hp?f=43&t=45368 )

[martossien]

Find for windows VLC

 

C:\ffmpeg\rtmpdump\rtmpdump -v -r "rtmp://192.168.0.19/flvplayback/myStream" --live -o - | "C:\Program Files (x86)\VideoLAN\VLC\VLC.exe" -

 

if you find other solution without rtmpdump ...

 

Now install e2 transcoder ...

[martossien]

ok some news :

I receive the new electric power 3a of raspberry pi3

and NOW the transcoding works at 25 ftp at 1080HD perfectly :

config.txt works for me

core_freq=580
arm_freq=1380
over_voltage=4
disable_splash=1
gpu_mem=320
temp_limit=75
sdram_freq=460

 

ffmpeg -benchmark -threads 4 -c:v h264_mmal -i http://192.168.0.28:...:EEEE0000:0:0:0: -c:v h264_omx -s 320x240 -pix_fmt yuv420p -bufsize 3000k -c:a libmp3lame -ac 1 -ar 22050 -f flv -metadata streamName=myStream tcp://0.0.0.0:6666

 

with this parameters i have 25 fps and stay under 300 K /s ! so perfect for my smartphone where i am not at home ...

 

For e2trancoder

 

config.php

 $conf["parameters"] = "-i {stream_url} -c:a aac -q:a 1 -strict experimental -c:v libx264 -crf {crf}  -profile:v baseline -filter:v yadif -vf \"scale=trunc(oh*a/2)*2:min({width} \,iw)\" -r 24 -map 0:a:{audio_id} -map 0:v:0 -hls_time 10 -hls_wrap 6 {stream_dir}ystream.m3u8";
to

 $conf["parameters"] = "-threads 4 -c:v h264_mmal -i {stream_url} -c:v h264_omx -s 320x240 -pix_fmt yuv420p -bufsize 3000k -c:a libmp3lame -ac 1 -ar 22050  {stream_dir}ystream.m3u8";

 

Go to test ...


 

[martossien]

some old channel in mpeg2 we must change to

 $conf["parameters"] = "-threads 4l -i {stream_url} -c:v h264_omx -s 320x240 -pix_fmt yuv420p -bufsize 3000k -c:a libmp3lame -ac 1 -ar 22050  {stream_dir}ystream.m3u8";

 

...

[martossien]

ok because we can't choose the config depanding the channel, we must use th auto find decoder of ffmpeg  of so i this case we must don't use the parameters : -c:v h264_mmal ( hardware decoders but only x264 )

so i try

ffmpeg -threads 8 -i http://192.168.0.28:...:EEEE0000:0:0:0: -c:v h264_omx -s 480x330 -b:v 350k -c:a libmp3lame -ac 1 -ar 22050 -f flv -metadata streamName=myStream tcp://0.0.0.0:6666

and works for all channel

 

the change can be -s 480x330 and -b:v 350k , first is resolution size and second video bandwith .

In my home i have adsl connexion and 2 children and i wife SO i can only use 380 k in upload before a war ( adsl is asynchronous my upload the uplaod become your download where your are external so 1 M max so only 380 K )

 

test in progress ..
 

[martossien]

OK now works with beautifull WeB GUI of e2transcoder ! ( thank's to the autor for this works and help)

Bug 1

the h264_omx dont works with m3u8

so

Bug 2

we use the h264_mmal and libx264 (sofwarre ) it's works with mpeg4 channels but not mpeg2 channel ...

we are working on it

 

For now my config file :

 

 cat /var/www/html/admin/config.php
<?php
  //mandatory configuration
 $conf["username"] = "root"; //username to access DB transcoder
 $conf["password"] = "xxxxxxxxxx"; //password to access DB transcoder

 $conf["stream_dir"]="/var/www/html/stream/"; //full path of stream dir
 $conf["db_stream_port"]="8001"; //enigma2 stream port
 $conf["command"] = "/usr/local/bin/ffmpeg";   // path of avconv or ffmpeg executable , if avconv of ffmpeg installed from package only need executable name
 //$conf["command"] = "avconv";   // path of avconv or ffmpeg executable , if avconv of ffmpeg installed from package only need executable name
 $conf["stream_web_dir"] = "/stream/"; //web url folder of stream

Little bug :

1)

failed to open vchiq instance

brutal solution :

sudo chmod 777 /dev/vchiq

2)

After long time :

"tvservice-client: Failed to connect to TV service:" -1

i think it's a powersave with hdmi

sudo shutdown -r now  ( ok ok i must find other solution )

[martossien]

bug

1)

better solution : ( not make sudo chmod 777 /dev/vchiq after reboot )

sudo usermod -a -G video www-data

[martossien]

find solution to check the codex of flux

 

ffprobe http://192.168.0.28:...:EEEE0000:0:0:0: 2>&1 >/dev/null |grep Stream.*Video | sed -e 's/.*Video: //' -e 's/[, ].*//'

 

return :

 

h264
or mpeg2 channel :

 

return :

 

mpeg2video
