I have a file which does not playback properly in any software.
It has an mpg extension. Its MediaInfo screenshot is attached which shows its detailed audio / video formats.
While trying to playback in VLC Player, an error message comes up which says 'the required video / audio codecs are not found'. However, the audio of the file does playback but no video (blank screen).
While trying to playback in Womble's MPEG Video Wizard, the video plays back normally but there is no sound (no audio). There is no error message though.
Avidemux also plays back the video part only, with no sound. Attached is a portion cut out through Avidemux and saved in the only Muxer it allowed for this file, AVI Muxer. The saved file when played back in VLC plays only the audio part.
Can anyone advise me how I can successfully edit out a portion from the parent file?

The avi sample works in potplayer. But it has some strange video properties:
General Complete name : E:\Downloads\aatemp1.avi Format : AVI Format/Info : Audio Video Interleave File size : 3.78 MiB Duration : 15s 415ms Overall bit rate : 2 059 Kbps Video ID : 0 Format : 0x01000010 Codec ID : 0x01000010 Duration : 15s 415ms Bit rate : 1 796 Kbps Width : 640 pixels Height : 480 pixels Display aspect ratio : 4:3 Frame rate : 29.970 fps Bits/(Pixel*Frame) : 0.195 Stream size : 3.30 MiB (87%) Audio ID : 1 Format : MPEG Audio Format version : Version 1 Format profile : Layer 2 Codec ID : 50 Duration : 15s 386ms Bit rate mode : Constant Bit rate : 96.0 Kbps Channel(s) : 2 channels Sampling rate : 44.1 KHz Compression mode : Lossy Stream size : 180 KiB (5%) Alignment : Aligned on interleaves Interleave, duration : 26 ms (0.78 video frame)
Avidemux for both the video and audio. However, if we dont use the copy mode, there are so many options for both video and audio. Can you help me choose / give some clues to what options should I use to save it correctly? The Output Format dropdown does not let me use any other muxer than AVI to save this file.
The original file already has a very-low quality. Reencoding it will make its quality go even worse.
Are you sure that's what you really want?
Thank you very much for this useful, informative reply.
It impressive how you know what software has been used to mux the original file. So if it was muxed incorrectly by the Mencoder, can I use Mencoder to correct this file now? If I want to use Avidemux, which options in video and audio should I use to increase my chances of saving this file normally? Otherwise I can use ffmpeg (I have already downloaded it) but have never used the command line editing before so let me google it as Baldrick says and I will let you know if few minutes the result.
