    Exclamation Issues with choppy audio and video

    Hello, relatively new user here. I'm having issues primarily with sound, but also video. I have VLC Media Player as well as GNOME Player and when trying to play an MP4 file neither program will play it properly. As for hardware I'm using an Acer Aspire One ZA3 net book, with an intel Atom and running Lubuntu only. VLC will play the video properly for the most part, but the audio skips terribly. GNOME will both play the audio and video but at an increased rate of speed while skipping terribly, and I see no controls to adjust this. I tried installing the restricted extras which fixed the most of the video issues in VLC, but did not effect GNOME. Also tried running the trouble shoot for sound and was able to get the "Front and Center" audio clip to play, but again it was choppy. The rest of the sound trouble shoot results were as follows:

    Not sure what my next step should be, or if I missed a step somewhere. Any input would be helpful, thank you.

    Re: Issues with choppy audio and video

    Netbooks don't have enough power to playback all video files without stuttering.
    You can transcode the video to a lower resolution or to a codec specifically supported by your GPU to get better results.

    MP4 is just a container. The actual video and audio codecs could be almost anything. So, first, we need to know what the video and audio encodings are, then the resolution. Use
    mplayer -identify -frames 0 {name-of-m4-file.mp4}
    to discover this data. There are other ways too - I'm positive that VLC has this data in the menu somewhere.

    Re: Issues with choppy audio and video

    I'm not sure why the audio and video would be choppy with only lubuntu, originally I was running Windows XP and there was no issue with playback.
    I couldn't use the terminal command you listed, it only gave an error message. this was probably my fault, I'm not all that great with the system yet, results were as follows:
    bekah@BleachOrchid:~$ mplayer -identify -frames 0Breaking Bad S1E01-Pilot.mp4

    I was however able to find the information in VLC as you suggested, the audio and video codecs from VLC were as follows:
    Stream 0
    Type: Video
    Codec: H264- MPEG-4 AVC (part10)(avc1)
    Resolution: 480x320
    Frame Rate: 25
    Decoded Format: Planar 4:2:0 YUV
    Stream 1
    Type: Audio
    Codec: MPEG AAC Audio (mp4a)
    Channels: Stereo
    Sample Rate: 44100 Hz

    Run this command:
    Code:
    echo "options snd-hda-intel position_fix=1" | sudo tee -a /etc/modprobe.d/alsa-base.conf
    See if it's any better after reboot. If not, give more info: https://wiki.ubuntu.com/Audio/AlsaInfo

    Re: Issues with choppy audio and video

    Side note: Spaces need an escape character in front of them. The command would have been:
    Code:
    mplayer -identify -frames 0 Breaking\ Bad\ S1E01-Pilot.mp4
    Autocomplete (hitting Tab) is very useful...

    You are amazing, I love you. Fixed everything in both GNOME and VLC. What was that?

    Sorry, been away. Well, seeing those codecs and tiny resolution, pretty much any computer, including most smartphones should play that easily. So the issue is somewhere else.

    All the other issues you posted were just because the filename had spaces and it wasn't either quoted "like this.mp4" or escaped. Tab completion rocks. Keyboard jockies like me LOVE tab completion - so we don't have to type much at all, just 1 or 2 characters.

    I see that Temüjin knew/guessed the issue. I'd never have come up with that, as I don’t have any machines with Intel audio/video. Glad the simple fix is working. I hope it is permanent - should be until you re-install the OS or do a major Ubuntu upgrade. Be certain that you store this command somewhere. ... really it just modifies a config file.
