No sound from internal speaker #19

Open lidense opened 1 year ago

lidense commented 1 year ago

I compiled from github on my M5stack Core 2 but I get no sound although I see the .ts files being dowloaded.

Thank you for your comment!

Please check #15.

lidense commented 1 year ago

There are 2 URLs that I would like to listen to: https://as-hls-ww.live.cf.md.bbci.co.uk/pool_904/live/ww/bbc_radio_scotland_fm/bbc_radio_scotland_fm.isml/bbc_radio_scotland_fm-audio%3d96000.norewind.m3u8 AND https://radioitaliasmi.akamaized.net/hls/live/2093120/RISMI/master.m3u8 I have a M5stack Core 2 with internal speaker

I used this main.cpp: examples/M5Core2WebRadio

There is no sound coming out of the speaker. For the first URL I can see messages from serial indicating that the buffers are being filled but no sound coming out while with the second URL there is nothing at all. I have tried with m5stack/M5Core2@0.1.3 but no success. Thank-you for your help. Regards

Thank you.

These URLs may have different problems.

The first URL causes a problem in conversion from ts to aac. To solve it, I have to modify AudioGeneratorTS.

The second URL returns URLs which have relative path. Here is actual playlist which the second URL( https://radioitaliasmi.akamaized.net/hls/live/2093120/RISMI/master.m3u8 ) returned.

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=98730,CODECS="mp4a.40.29"

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=98730,CODECS="mp4a.40.29"
../../2093120-b/RISMI/stream02/streamPlaylist.m3u8

The program should request to https://radioitaliasmi.akamaized.net/hls/live/2093120/RISMI/stream02/streamPlaylist.m3u8 or https://radioitaliasmi.akamaized.net/hls/live/2093120-b/RISMI/stream02/streamPlaylist.m3u8.

However, it does not support relative path, and requests to https://radioitaliasmi.akamaized.net/hls/live/2093120/RISMI/stream02/../../2093120/RISMI/stream02/streamPlaylist.m3u8.

So, I have to make the program support relative path.

Thank-you for your reply, I would like to have more details to understand how I can try to modify the code to adapt to these urls? Can you help? Can you explain what you need to change and why? Thanks and regards Dave

Do you think it is possible to adapt the app to listen to these streams? I would like to learn how to do it, do you have some documents that I can read on how to go from .ts to.aac? Can you recommend an online script which allows to analyze a .ts stream to understand how to do the job? Thanks Dave

I have tried to understand why I do not have sound using this weblink: https://as-hls-ww.live.cf.md.bbci.co.uk/pool_904/live/ww/bbc_radio_scotland_fm/bbc_radio_scotland_fm.isml/bbc_radio_scotland_fm-audio%3d96000.norewind.m3u8

From what I undersand AudioGeneratorTS does not find the sync byte 0xFFF What can I do?
