@ nubc There's also a (more recent?) "ffmpeg-3.2.2-32bit-static.pet", built by rockedge and available from him via the first post in this thread. All needed dependencies are downloaded during the installation and it worked for me OOTB in both Tahr 6.0 and in Mikeslr's wonderful Tahr 6.06. (Though of course, as Mike Walsh cautions above "Mind you, that's not to say it'll work for anybody else..."  )

The answer to the user's problem is probably VP codec (html5/webm) related. Older youtube videos were encoded with VP8 codec whilst newer ones are encoded with VP9/10 codecs. Older ffmpeg packages did not include the VP9/10 codec so yes, updating the ffmpeg package will probably sort out the problem. BTW - There is always an alternative way of doing things. Most (if not all) youtube videos are also encoded to the mp4 format. You can either stream or download a video using its mp4 download link. |

Probably some issues are incorporated by google itself to sabotage firefox. Toward the bottom of the article youtube and google are accused of sabotage., Former Mozilla exec: Google has sabotaged Firefox for years "Not the first accusations And Nightingale is not the first Firefox team member to come forward and make such accusations. In July 2018, Mozilla Program Manager Chris Peterson accused Google of intentionally slowing down YouTube performance on Firefox. He revealed that both Firefox and Edge were superior when loading YouTube content when compared to Chrome, and in order to counteract this performance issue, Google switched to using a JavaScript library for YouTube that they knew wasn't supported by Firefox. YouTube page load is 5x slower in Firefox and Edge than in Chrome because YouTube's Polymer redesign relies on the deprecated Shadow DOM v0 API only implemented in Chrome. You can restore YouTube's faster pre-Polymer design with this Firefox extension: https://t.co/F5uEn3iMLR — Chris Peterson (@cpeterso) July 24, 2018 At this point, it's very hard not to believe or take Nightingale's comments seriously. Slowly but surely, Google is becoming the new Microsoft, and Chrome is slowly turning into the new IE, an opinion that more and more users are starting to share [1, 2, 3]. Reminds me of the time Microsoft used private APIs to make IE better. Google is the new Microsoft. The tables have turned :p — Federico Ramirez (@gosukiwi) July 24, 2018" And don't forget, google is your friend. . |

Looks like 915G I already have ffmpeg installed. Before I checked, I installed ffmpeg 3.2.2 32-bit static, but I don't know where it installed. Last edited by nubc on Wed 17 Apr 2019, 19:10; edited 1 time in total |

If you installed it via the puppy package manager you can find the list of files for ffmpeg in /root/.packages |

It's not clear which version you suggest is listed, but ffmpeg 3.2.2 32bit static is listed in /root/.packages. PPM shows ffmpeg 2.2.9 i686 as "found package." PPM also shows ffmpeg 3.2.2 as "installed package," and recommends not to do that. Last edited by nubc on Wed 17 Apr 2019, 19:32; edited 1 time in total |

@ nubc:- Look in /usr/bin. You should find ffmpeg and its associated binaries in there. Mike.

Properties of ffmpeg in usr/bin show 33 MB and this text
I don't know what the associated binaries are, but I made the symlink to avconv. I tried a YT video and got the HTML5 error. Maybe I need to reboot. Or maybe I need to uninstall both ffmpeg, and reinstall 3.2.2 |

I found the following (but it's a 2016 thread)"
[SOLVED] Firefox 49, no H.264 support @ forums.gentoo.org but you can probably apply the same principle if you know what version of ffmpeg firefox is looking for. If you let us know which version of firefox you're using then maybe we can figure it out. However, I will point out that the version of ffmpeg your using must be compiled with H.264 support. As an alternative to the ffmpeg approach apparently this codecs can also be found in the plex media server but I would take the ffmpeg approach. |

I ran ffmpeg from terminal and got version 3.2.2-static I searched for libavcodec.so.56, libavcodec.so.57, libavcodec-ffmpeg.so.56, and libavcodec-ffmpeg.so.57 but apparently they do not exist on my system. I do find libavcodec.so.54

Maybe try a newer version of this lib (part of ffmpeg) such as libavcodec-extra58 or if using an earlier version make sure they are the "-extra" version. I found these libs by looking at the dependencies for firefox at https://packages.debian.org/sid/firefox Edit 1 If you have libavcodec.so.57 on your system then my guess is the extra version from strech should be compatable with your system. https://packages.debian.org/stretch/libavcodec-extra57 I can verify that all youtube html video formats work on dpup strech because I use firefox on dpup strech; so therefore this version should be new enough. The version of libavcodec.so.57 that you have on your system might not be compiled with all the html5 video codecs. Also note that I might be using an older version of firefox than you so I can't guarantee this verson of the codec is new enough. Edit 2 To find even oder versions of libavcodec-extra look at the bottom right of the page where it says "similar packages" Edit 3 I worry that if you have multiple versons of this file on your system that firefox might not find the right one. Consider removing all but the one from libavcodec-extra57 or altenativly either use LD_PRELOAD or a modified LD_LIBRARY_PATH at firefox startup to make sure it finds the right version. |

@ s243a As I said above, a search of my system files does not find libavcodec.so.57. How can I remove it if I can't even find it? Okay, what if I download extra57, what do I do with it? @nic007 Do you imply that Seamonkey 2.48 can playback HTML5 videos? @666philb & mikeslr Why am I the guinea pig (again)? Shouldn't the developer of Tahrpup be the guinea pig? Although it's a community edition, the Ubuntu variant is a main branch of Puppy. I don't think it's expecting too much that a Puppy be able to play Youtube videos. Pale Moon is obsolete before it is published. How does that happen?

When you click on a youtube link in your browser a new youtube page opens with their embedded html5 player playing the video via streaming. My understanding is that this is independant from which encoders (if any) may be installed on your machine as long as your browser is new enough. When you are not using their embedded player you need the codecs. I may be totally wrong though. |

Installing libavcodec-extra57 may have fixed it. I haven't encountered the error so far. |
