  • ffmpeg converted file from H264/AAC to MP4/MP2 but Archos still complans

    17 mai 2015, par barrycarter

    My Archos video player won’t play H264 video or AAC audio without a
    non-free special plugin (which may not even be available for purchase
    anymore), so I tried to use ffmpeg to convert a file in this format to
    a format free of those two encodings, but Archos still complained that
    the resulting file had AAC audio encoding, though it no longer
    complained about the video encoding. Details :

    (I realize "ffmpeg -i" is incorrect usage, but it’s really useful, as above).

    • I then converted it using ffmpeg -i input.mp4 -acodec mp2 output.mp4 (note the video conversion is implicit because the
      output file has an mp4 extension). The resulting file (13.8M) is at :

    Even though there’s no mention of AAC above, Archos claims the file
    contains AAC encoding and refuses to play it without the plugin.

    What am I doing wrong ? Is there a better way to do this ?

  • HTML5 video (mp4) won't seek properly with Firefox 37/38/39 on Apache

    10 juin 2015, par degenerate

    Edit : Turns out this is actually a Firefox bug.

    Firefox will not seek properly past the loaded point in any mp4. It doesn’t matter what program encoded the file or where it came from ! I am hosting on Apache 2.2.29

    Obvious things you will probably ask me :

    • Yes I used -movflags faststart when encoding with ffmpeg
    • Yes AddType video/mp4 .mp4 is set correctly
    • This is a new problem without any changes to the server ; only the newer firefox (version 36, 37, 38+) has this issue.
    • Chrome works WONDERFULLY so this is a problem isolated to Firefox, and only started happening sometime in 2015 with one of the newer versions. Nothing was changed on the server.

    Firefox makes hundreds of requests after seeking to any point in the mp4. The closer to the end of the file, the more requests are made. Eventually after several minutes it will stop sending requests and finish playing ; I assume when this happens it has downloaded the entire mp4.

    Notice the byte-range request on chrome has a definitive size, yet all the requests one firefox are XXXXXX- with no ending byte...

    (FIREFOX = BAD, hundreds of requests — right click image to see full resolution)

    Firefox makes thousands of 206 requests on seek

    (CHROME = GOOD, one single request)

    Chrome makes one request as expected

    Regarding keep-alives : I tried turning keepalive on and off. I get the same results in both browsers. Chrome is always able to seek, firefox is never able to seek.

  • How to convert video to Archos compatible format ? (details below)

    19 mai 2015, par barrycarter

    EDIT : Rewriting completely to reflect what I’m actually trying to do.

    Below are the results of "ffmpeg -i" on two files that I know my
    Archos player will play properly.

    My question : what ffmpeg, vlc, mencoder, etc commands/options do I
    need to convert an existing video to either one of the two formats
    below ?

    In other words, how do I make non-Archos-compatible videos compatible
    with Archos ?

    (note : Archos has confirmed they no longer even sell plugins to view
    other types of videos, so transcoding is my only option)

    [mpeg4 @ 0xa5deb80] Video uses a non-standard and wasteful way to store B-frames ('packed B-frames'). Consider using a tool like VirtualDub or avidemux to fix it.
