We'll go over a few efficient ways in this post so you may resolve the issue and enjoy watching and listening to your favorite movies and songs. But don't worry cause this issue can be fixed with some simple methods. It can be quite frustrating to encounter the "VLC Could Not Open the MP4A Audio Encoder" error, especially when you are enjoying your movie night or fancy music. There are several reasons why this error might occur, including missing codecs, corrupted media files, an outdated VLC version, and more. The error message indicates that VLC is unable to find or use the MP4A/MPGA audio encoder, which is required to play or convert certain audio files. Like this user from VLC forum, you may encounter some errors like "VLC Could Not Open the MP4A Audio Encoder" and "VLC could not open the MPGA audio encoder". VLC Media Player is a popular media player that supports playing a wide range of audio and video formats. It's behavior is likely to have changed since then.When trying to transcode: "VLC could not open the mp4a audio encoder".So why am I getting this error message and why do I not have any audio? I hesitate to say a lot about PotPlayer because the version I'm using is four years old. But there are several other factors which may cause other computers to behave differently: different version of VLC, different settings in VLC (accelerated video output, hardware YUV->RGB conversion, etc.), different graphics cards (with most renderer's YUV data is passed tot the graphics card and the graphics card performs the YUV to RGB conversion, Windows GDI is the exception, when using it VLC converts YUV to RGB and then passes RGB data to the graphics card), different graphics card drivers, different settings in those drivers, different codecs and different containers. So, on my computer, there is no renderer in VLC 2.2.4 that will display all HD videos correctly. So rec.709 videos are displayed incorrectly, rec.601 videos are displayed correctly. On the other hand, the Direct3d, DirectX, Direct2D, and Windows GDI renders always use rec.601. So rec.709 videos are displayed correctly, rec.601 videos are displayed incorrectly. On my computer VLC with the OGL renderer always uses a rec.709 matrix. But whether you get the "right" colors depends on which renderer is used and what matrix was used to create the video. I'm not sure what the default renderer is when you first install VLC. He means that VLC does not correctly display flagged_rec601.mkv by default. I tried some Video Renderers and there's no changes. On PP I have all the 'same' colors (imperceptible), but flagged_rec601.mkv show the grays a bit more bright flagged_rec601.mkv looks a bit orange (red bar 208,8,0) Hi thanks, I have on VLC the same things on unflagged_rec709.mkv and flagged_rec709.mkv (red bar 191,0,1). Exactly what you see when you play these videos will vary depending on the player, the renderer the player is using, the graphics card you are using, and the graphics card's settings. When the video doesn't specify the color matrix the general rule is to use rec.601 for SD video, rec.709 for HD video. MPCHC on my computer displays all three with the correct colors. The magenta bar should be about 191,0,191. Ie, the red bar should be 191,0,0 (r,g,b). The RGB components of the color bars should be within 1 or 2 units of 0 or 191. Unflagged_rec709.mkv contains YUV 4:2:0 video with rec.709 colors, but the matrix isn't flaggedįlagged_rec709.mkv contains YUV 4:2:0 video with rec.709 colors, flagged as rec.709įlagged_rec601.mkv contains YUV 4:2:0 video with rec.601 colors, flagged as rec.601
