Video rendering - no audio
Weird one...
Suddenly, on my Windows 7 laptop, when I render a video there's no audio content :-( I wonder if anyone has some insight, maybe from a similar problem they have solved Here's some info: - copied project to my main studio PC (Win 10) - renders fine (video & audio) - tried other video projects on the laptop - same issue - laptop audio device is ASIO4ALL over inbuilt audio, studio PC is ASIO (RME) - audio playback of the project on the laptop in Reaper is fine - When rendering I can see audio waveforms on the render dialog - if I import the rendered video back into Reaper, there's definitely no audio - tried a fresh portable Reaper install - same issue - VLC 3.x and ffmpeg (full, shared version) installed (on fresh portable inst too) - tried MP4, WEBM and MOV output formats - no joy - tried AAC, MP3 and Vorbis audio output formats - no joy Any suggestions? Thanks |

Another user just the other day reported the same problem, video and audio plays fine in Reaper but the render has no audio.
https://forum.cockos.com/showthread.php?t=242358 https://forum.cockos.com/showthread.php?t=242951 No solution though, but... Maybe if the two of you compare render settings or setups or something, you might suss out what the problem is...

OK - I might have tracked this issue down...
It looks like installing the FFMPEG SHARED libraries (in /reaper/userplugins/) on Windows 7 is the fatal combination... Uninstalling (i.e. deleting) the FFMPEG SHARED files allows rendering video correctly - i.e. with both video and audio tracks - albeit with no MP4/H.264 options :-( On my studio PC, which is Win10, there's no problem using the FFMPEG SHARED libraries. With the current issues regarding where to find the FFMPEG SHARED libraries, I wonder if there is a Windows 7 specific build anywhere that anyone knows of. |

Go to Preferences > Media > Video/Import/Misc and click the "Show the available decoder information" and let us know what it says there. Here, where it works for me flawlessly (so far), it says: Code:
========== ffmpeg/libav ========== ffmpeg/libav DLL decoder v58.91.100 Loaded from: P:\Reaper6\UserPlugins\64\avcodec-58.dll ffmpeg/libav configuration: --disable-static --enable-shared --enable-gpl --enable-version3 ...

Fabian,
Hi. My Prefs/Video preferences and video decoder information are below. Despite the highlighted text on the video decoder information screenshot, I've searched my PC for "avcodec-58.dll" and it only exists in the Reaper\UserPlugins folder (there is an ffmpeg.dll in the Reaper/Plugins folder but I presume that is the default, limited Reaper ffmpeg plugin) I can't find a version number for the FFMPEG shared files in the zip file I've used but the archive name suggests a compilation date of 16 Aug 2020, plus I can see that the extracted DLLs are dated 17 Aug 2020. Is that the same version as yours? |

OK, it looks like it was a dodgy build of FFMPEG Shared that I had downloaded....
I finally found a link to download "FFMPEG v4.3.1 SHARED" files and, having installed that version in Reaper on my Win 7 laptop, I can now render video plus audio using H.264 compression :-) Many thanks to Fabian for pointing me in the right direction... For the benefit of future forum searches, here's exactly what I did to successfully install the full, shared FFMPEG version on 64-bit Windows 7 ... 1. Deleted any existing FFMPEG-related library files from my reaper installation /userplugins folder: - ffmpeg.exe - ffplay.exe - ffprobe.exe - avcodec-58.dll - avdevice-58.dll - avfilter-7.dll - avformat-58.dll - avutil-56.dll - postproc-55.dll - swresample-3.dll - swscale-5.dll 2. downloaded v4.3.1 ffmpeg SHARED archive from: - https://www.gyan.dev/ffmpeg/builds/f...full-shared.7z 3. Extracted the files in the above archive from its /BIN folder (same as list in 1. above) to my reaper installation /userplugins folder Close and run Reaper and you will now have extra MOV/MP4 render option, including H.264 compression (which saves rendering uncompressed and then using Handbrake to compress them) |

It doesn't matter, if you have a flunky ffmpeg installation you need to fix it, and it works the same way on W10 as on W7. So try what the Uncle suggests, and then render your file again to see if it works. It is simple.

I followed your directions, rendered my video file, and what do you know, this time the rendered file had video AND AUDIO. Thank you SOOOOOO much. This problem was driving me CRAZY, not to mention the hours and hours I spent asking questions and trying to figure it out. Quote:

I followed the above...the new FFmpeg is 4.4 now. I have the H264 option but my audio only shows up when using 16 or 32 pcm. No mp3 no aac. Any thoughts?

https://forum.cockos.com/showpost.ph...06&postcount=9 Try to install a pre-4.3 version, like 4.2.3, hopefully that solves teh mp3 rendering problem.

For future searchers (this post is the first Google result for "REAPER video export no sound"), this is what fixed it for me:
