I have a low quality, but playable .webm video. It was recorded from a webrtc live stream that seems to have been on a bad connection. There are not many video frames and the audio cuts out for a moment. I am trying to convert the video to .mp4 with the following command:
avconv -i foo.webm -strict experimental -movflags faststart foo.mp4
I get this error repeated at least 100x:
[opus @ 0x268d7a0] LBRR frames present; this is unsupported [opus @ 0x268d7a0] Error decoding a SILK frame. [opus @ 0x268d7a0] Error decoding an Opus frame.
The resulting .mp4 video is even significantly worse than the .webm video. The audio cuts out for good and there are even less video frames. Is there a way to get this video to convert more accurately in spite of the issue it is encountering?
