<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><div>Folks,</div><div><br></div><div>I have created a custom file format that essentially takes a mp4 or mkv file and adds some additional information to it. The original video and audio streams are not tampered at all. I also have implemented a stream filter module within vlc to handle this new file format.</div><div><br></div><div>This technique works 99% of the time. I have been able to play movies in the original format as well as the new format within vlc.</div><div><br></div><div>Yesterday, I ran into a subtle problem. While playing a media file with my new format, the video works okay but the audio fails. The original media file plays okay.</div><div><br></div><div>I have a feeling that vlc is taking a different graph path when playing this file. I am wondering if there is a way to:</div><div>1. Check what audio filter is
vlc using with the original file.</div><div>2. Force vlc to use the same audio filter when using the new file, ideally by command line options.</div><div><br></div><div>If you have some other idea or suspect something else is going on, I would appreciate it if you could share your thoughts with me.</div><div><br></div><div>Thank you in advance for your help.</div><div><br></div><div>Regards,</div><div>Peter<br></div><div><br></div><div><br></div><div></div></div></body></html>
