RetroArch 1.75 streaming not work

Cire

After update retroarch to 1.75, there is a function to stream on twitch or youtube. But when I click start streaming it will force quit, does retropie not support this function?

Pi Model or other hardware: 3B+
Power Supply used: Original pi power supply
RetroPie Version Used: 4.4

Are you using the official 4.4 image for RetroPie ?
Does it work if you're using it outside of RetroPie (i.e. Windows/macOS/Linux ) ?
Start a game with verbose logging enabled from the Runcommand launch menu and then get the log file (/dev/shm/runcommand.log) of the crash and upload it to pastebin.com, maybe we can spot the error.

I haven't got a change to test this. I found a comment on the PR that implemented this feature in RetroArch which suggest it needs FFmpeg >= 4.0.1 for it to work. The RetroPie (well, Raspbian) image includes the 3.2.10 version and this might cause problems using this features.
Otherwise, your log doesn't show any obvious error, though the last messages are from the ffmpeg (libav) library.

FFmpeg

Thanks, I will try update it later

@mitu the latest raspbian supposedly includes ffmpeg with hardware acceleration. Haven't gotten around to testing it yet though

OK, so I did a brief test over the week-end and tried the settings (from this topic to try and record first gameplay using a Twitch/YT compatible format.
As noticed in that topic, you get a bus error (the crash you noticed) if you don't use a proper acodec. If I use libmp3lame for acodec, then I get a crash. Unfortunately, the ffmpeg that comes with Raspbian (and RetroPie) doesn't seem to have that audio codec built-in (it's considered non-free and not enabled in the Raspbian build). I haven't got a chance to test if using aac for acodec fixes the crash, but I'll give it a try later on.

I try change acodec to aac, it will not crash but very laggy
I have no idea how to upgrade ffmpeg to 4.0, the latest ver. still 3.2
