Why are some files soo large when using rtmpdump?

[korexaj]

I have noticed that rtmpdump uses crazy amount of storage compared to other recording methods. e.g.

I was recording a stream using ffmpeg (for chaturbate) and after a while i thought i should record using rtmpdump to see difference in size.

The results are that the recording using ffmpeg came to around 300Mb (36min long) in 720p whereas when using rmtpdump the exact same stream came to around 900Mb and was 23min long because both werent started at same time.

So why a HUGE difference in size?

ffmpeg does not work for rtmp streams on chaturbate. If you got that working, I would like to hear how.

I can record CB hls streams with ffmpeg, but still prefer rtmpdump to get flv file.


ffmpeg:

ffmpeg.exe  -i "https://edge60.stream.highwebmedia.com/live-edge/amlst:aalliyahh-sd-3567994de62294038d27c9b7680f7d8e4e7ae9203f3ac912abd2993f4e0e786c_trns_h264/playlist.m3u8" -c copy c:\aalliyahh_2017.12.07_00.51.53.944.ts

rtmpdump:

rtmpdump.exe  -v -r "rtmp://edge36.stream.highwebmedia.com/live-edge" -a "live-edge" -f "WIN 26,0,0,151" -W "https://chaturbate.com/static/flash/CBV_2p680.swf" -p "https://chaturbate.com/aalliyahh/" -C S:***** -C S:aalliyahh -C S:2.680 -C S:*****71f9ed644700489146f67c1a8e60b1e2ec47d9ca92be44319a94be9c07623967f94d97042b87f795abf81d1f2fe9afed0d8df29862cf208ae797768e433 -C S:*****f2337c0e8cc451a3c501564e164370953a1e09d4116065457ff1bdca824 -y "mp4:wowz://origin36.stream.highwebmedia.com/live-origin/aalliyahh-sd-*****58103439c905a653db090179c3e4b80c402d379875cd983497e18baf79d_trns_h264_480p" -o "c:\aalliyahh_2017-12-07_00-52-04-666.flv"

After 10 min. of recording my flv file appears to be two times smaller than my ts file. Resolution is the same, 640 x 480.

sorry i meant that the ffmpeg uses the hls stream whereas rtmpdump uses the rtmp streams. for me the files are alot smaller when using hls streams (via ffmpeg). i prefer rtmpdump due to less errors but man the thing is eating up my hard drive like there is no tomorrow

few things i'd like to mention are that comparing your command with mine, "-f" parameter is missing on mine and also i'm using "mp4:rtmp" whereas you're using "mp4:wowz"

are you using any specific script? not that the scipt should effect the file size

I actually get .flv file with ffmpeg as well, just for the sake of test I ran one .ts line to show the difference.

Instead of: -c copy c:\model.ts, I do: -c:v copy -c:a aac c:\model.flv,

and then my .flv file I made with ffmpeg is of the same size like .flv file I made with rtmpdump.

$model = $CmdLine[1]
runwait('cmd.exe /c curl.exe -v -k https://chaturbate.com/' & $model & '/ | CLIP','',@SW_HIDE,'')
$sData = ClipGet()
$sData = StringTrimLeft($sData,StringInStr($sData,"initHlsPlayer(jsplayer, 'https://")+24)
$sData = StringTrimRight($sData,(StringLen($sData)-3)-StringInStr($sData,'m3u8'))
$dtime = @YEAR & '-' & @MON & '-' & @MDAY & '_' & @HOUR & '-' & @MIN & '-' & @SEC & '-' & @MSEC
runwait('cmd.exe /c ffmpeg.exe -i "' & $sData & '" -c:v copy -c:a aac c:\' & $model & '_' & $dtime & '.flv','',@SW_SHOW)

its weird but i will try playing around with the parameters to see what is causing this. its definitely not normal to have same stream like 2/3 times larger.

maitrang,

after having a look at a number of your posts on this forum I wonder how much educated are you ?

You appear to be behind vietnamese travel agency with only a year of schooling or so.

You are on an international forum writing some local language, so give as at least a photograph
to see what is your post all about.
