not sure if you guys know, there's a half-ass method of ripping be-at.tv streams with livestreamer. i must state right away, if there is more than 1 "be-at.tv stream id" involved, livestreamer will most likely produce huge video file which will only play 5 minutes and will need fixing, BUT! it is still OK for mp3 converter feature.. basically, with livestreamer one can download lowest quality mp4 from be-at.tv which will contain only audio, but be still flv/mp4, so it needs to be converted to mp3 after... but in any case, this is command that i use:

1 wrote:
livestreamer BEAT_URL worst -o FILENAME.mp4

worst is for quality, which basically cuts down on data transfer.. after download is complete, it can be converted to mp3 with something like this:

2 wrote:
for %%a in ("*.mp4") do ffmpeg -i "%%a" -map 0:0 -acodec libmp3lame -ac 2 -ab 192k "%%a.mp3"
but that is ONLY in case you did "worst" quality, because then audio track is the only track and it becomes 0th track in 0th format.. if video download quality is ANYTHING but worst, then there will be video track along with audio track, and audio track becomes 1st, not 0th in the "list", so command changes by one digit:

3 wrote:
for %%a in ("*.mp4") do ffmpeg -i "%%a" -map 0:1 -acodec libmp3lame -ac 2 -ab 192k "%%a.mp3"
but thanks to stupid ffmpeg thing and the streams that be-at.tv produces, mp3 converting process car report like millions of errors, which will significantly slow down the process of conversion, because all these error messages have to be sent to terminal (cmd.exe in this case), so it cab be avoided by telling ffmpeg to be quiet, in case of faulty multi-id stream this actually saves double or triple time... so gotta add "-loglevel 0" to the command. it will not show any progress, i think, but in any case, it's way faster...

final wrote:
for %%a in ("*.mp4") do ffmpeg -i "%%a" -loglevel 0 -map 0:0 -acodec libmp3lame -ac 2 -ab 192k "%%a.mp3"

hopefully this helps someone...

thanks Slash and thankyou everyone who uploaded the mixes for this (FC, Alex)!!! :thankyou:

Wow, didn't expect that much share of data about this event :) thanks.
Is that that useful to convert to MP3 ? Why not an -acodec copy to keep quality ?

Also, is there an 1Mb/s Arte stream ? They usually do a decent 2.5Mb/s, and, that time, audio was very nice : 192k aac @48k  with 20khz cutoff.

No replay so far, and sometimes quality is better as live.

Thanks for log tip, slash.

it was about be-at.tv, they always do 192kbps audio. plus i don't think -acodec copy would do it, because we're converting to mp3, and video usually has audio as m4a or aac.

Indeed. Is that a scene rule or is someone using an MP3 only player nowadays ?

i don't know.... if none-mp3 formats are shared, usually someone shares mp3 later, so...

But please guys, NEVER do use livestreamer for ripping video from be-at.tv.

As you know slash, be-at.tv sometime is missing chunks in the best quality. If livestreamer would use a lower quality chunk in this case, or even would go to the next chunk, this could result in asychronous audio/video.

i've written above there, that is method can be erroneous, and with multiple "pieces" on be-at.tv, video file will end up huge but unreadable sometimes. that is why i've listed pretty much the method for sound-only download with livestreamer.

recently be-at.tv has been doing this maybe on purpose, but when i personally see that their broadcast starts with stream ID 5000 and ends with ID 5005 - i do not want to deal with that anymore... downloading multiple streams and putting them beat files together and then doing mp4s together and then converting to mp3... annoying..

ps. be-at..tv has audio and video together in every chunk, so there will not be asynchronous sound problems, in cases of missing chunks, there will be frozen video for a few seconds and missing audio...
