<p>The audio of my video file is faulty. I tried both VLC player and CLI <code>ffplay</code>.</p> <p>What I'm observing is that the audio is &quot;stuttering&quot; in the sense that it's silent for the most part with cracking noises every few seconds. I'd compare it to sound during fast forwarding or the sound from an old analog radio receiver when adjusting the frequency to switch between different radio stations. It doesn't last for longer than the blink of an eye, then the audio is silent again.</p> <p>Here is the output from FFmpeg if that helps:</p> <pre class="lang-none prettyprint-override"><code>$ ffmpeg -i faulty.mp4 ffmpeg version 7.0.2-static https://johnvansickle.com/ffmpeg/ Copyright (c) 2000-2024 the FFmpeg developers built with gcc 8 (Debian 8.3.0-6) configuration: --enable-gpl --enable-version3 --enable-static --disable-debug --disable-ffplay --disable-indev=sndio --disable-outdev=sndio --cc=gcc --enable-fontconfig --enable-frei0r --enable-gnutls --enable-gmp --enable-libgme --enable-gray --enable-libaom --enable-libfribidi --enable-libass --enable-libvmaf --enable-libfreetype --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-librubberband --enable-libsoxr --enable-libspeex --enable-libsrt --enable-libvorbis --enable-libopus --enable-libtheora --enable-libvidstab --enable-libvo-amrwbenc --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libdav1d --enable-libxvid --enable-libzvbi --enable-libzimg libavutil 59. 8.100 / 59. 8.100 libavcodec 61. 3.100 / 61. 3.100 libavformat 61. 1.100 / 61. 1.100 libavdevice 61. 1.100 / 61. 1.100 libavfilter 10. 1.100 / 10. 1.100 libswscale 8. 1.100 / 8. 1.100 libswresample 5. 1.100 / 5. 1.100 libpostproc 58. 1.100 / 58. 1.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'faulty.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf59.27.100 Duration: 02:50:15.25, start: 0.000000, bitrate: 1686 kb/s Stream #0:0[0x1](und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(progressive), 1280x720 [SAR 1:1 DAR 16:9], 1297 kb/s, 24 fps, 24 tbr, 90k tbn (default) Metadata: handler_name : VideoHandler vendor_id : [0][0][0][0] Stream #0:1[0x2](und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 381 kb/s (default) Metadata: handler_name : SoundHandler vendor_id : [0][0][0][0] At least one output file must be specified </code></pre> <p>I feel like I've encountered this issue before, but I don't remember if I just gave up or if there was a way to resolve it.

<p>I found a lot of family movies in my old Kodak DX6340 digital camera. Unfortunately, none of the editors (Filmora, Davinci, Movavi, MovieMaker) or any player (except Apple QuickTime Player) can display them correctly - the bar always appears on the right and at the bottom: <a href="https://i.sstatic.net/Lgo5KNdr.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/Lgo5KNdr.png" alt="pict 1" /></a> I spent many hours looking for the reason and it seems to me that it is because:</p> <ul> <li>Kodak used H263 as the codec H263 codec has a native (one of many) resolution of 352x288 (does not support 320x240)</li> <li>Kodak in its camera specifications: (Camera Manual) states that the videos are <strong>320x240</strong> and that is how they are played when I connect the camera to a TV with a cable or when I play them on my computer using QuickTime Player: <a href="https://i.sstatic.net/XIGgw3Wc.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/XIGgw3Wc.png" alt="pict 2" /></a></li> <li>The MediaInfo application gives the same size: <a href="https://i.sstatic.net/l20J0n9F.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/l20J0n9F.png" alt="pict 3" /></a></li> <li>And now the most important thing: MediaInfo gives the following data: <a href="https://i.sstatic.net/oZhYSPA4.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/oZhYSPA4.png" alt="pict 4" /></a> <strong>With/Height = 320/240</strong>, <em><strong>Original Width/Original height = 352/288</strong></em>, <strong>Display aspect Ratio = 4:3</strong> So, when I try to open this MOV in movie editors or players - those applications look at the wrong parameters. <strong>They should look at 320/240 and 4:3. And they look at 352x288 (additionally - it is not 4:3!)</strong> so then they artificially draw this black bar on the right and at the bottom.</li> </ul> <p>Is there any way to force the appropriate interpretation on the MOV header? For example, by modifying this header somehow? If anyone would like to see it on their own, I am attaching this MOV file: <a href="https://drive.google.com/file/d/1u77e-S2UZN7-2WAzSbkmo32EtkJ7Ikw4/view?usp=sharing" rel="nofollow noreferrer">link 1</a> Please do not let me crop/resize the MOV, it has only 320x240, I don't want to lose details (if I can say that 320x240 could have details...;-) ) and do not want to deform (stretch) the picture.</p>

<p>When I watch videos from my GoPro, the colors look much better in Dragonplayer (stock player with KDE).

<p>I have problem with ffmpeg properly recognizing a video encoded with Microsoft Fast Mpeg 4v2 codec. Apparently it's a software codec. VLC plays the video fine.
