Emulator Issues #8696
A/V Dumping Issues/Suggestions
Audio/Video Dumping has been greatly improved compared to what it was previously, but there are some glaring issues at hand that should be resolved.
1) Some games with variable frame rates do not get video dumped properly in Windows
This is due to VFW not supporting variable frame rate dumping and the current implementation for Windows. Linux does not have this issue as it uses FFmpeg. The ideal solution would be to replace the VFW process with FFmpeg for all OSes.
2) Some games have extra silent audio at the beginning of the dump
Most games do not have this issue, but usually VC titles are affected by this (as well as some Gamecube games)
3) No options to merge dsp/dtk audio and merge audio/video into a single file
Right now, the audio is dumped straight from the DSP and Streaming Audio, without the use of mixers. One option would be to combine the audio files after dumping. Similarly, it could be done with adding the audio to the video.
4) Some games do not dump at the proper speed
Seems mostly related to homebrew or VC MSX games with weird audio polling rates.
5) OSX Video Dumping non-existant
On last check, OSX video dumping does not work at all. Perhaps have OSX builds have FFmpeg on the buildbot
6) More codecs/file formats
Would be dependent on switching over fully to FFmpeg. Would also need some new UI created and code changes to accommodate this feature.
#3 Updated by Fog almost 5 years ago
Update on this ticket:
1 has been fixed in 4.0-8634.
2 still needs to be looked into, especially with the recent changes made in 4.0-8634.
3 and 4 are currently in progress under PR 3542 (the audio merging could be made easier once 3542 is merged)
5 will only require ffmpeg to be installed on the OSX buildbot with the cmake changes made in 4.0-8634.
6 is in the pipeline, but is not entirely important at this point and time.
