Forcing ffmpeg to capture unreliable ALSA audio stream
6 février 2015, par Peter BecichI am attempting to transfer some old Video 8 tapes to my computer, though an EasyCap USB stick and the motherboard’s sound line-in, on Ubuntu. I believe the arguments are correctly laid out below to capture from two independent streams, and encode them both into the output MP4 file.
ffmpeg’s detection of the ALSA stream is seemingly goofed up by the inconsistencies of the tape. In the failure case, only short blips of the tapes audio exist in the output MP4. The audio bitrate of the output file is less than 10 kbps, averaged out across the whole file. The output video seems to be fine, even though the low frames-per-second in the failure case log below.
The audio and video streams can be captured fine for short amounts of time before a source error occurs ; this provides the success case log. The failure case log was created by intentionally making an error in the source streams — turning on the camera makes a brief noisy signal.
Is there a setting that needs to be forced to keep ffmpeg recording the audio stream, even when the tape is blank or noisy ?
Could it be that the libfdk_aac audio encoder is tripped up by the low quality source ?
The relevant line ;
rawvideostream is piped to this in script at bottom :ffmpeg -pixel_format uyvy422 -s:v 720x480 -framerate 29.97 -f rawvideo \

ALSA buffer xrun induced by low quality source in ffmpeg capture
24 juin 2015, par Peter BecichI am attempting to transfer some old Video 8 tapes to my computer, though an EasyCap USB stick and the motherboard’s sound line-in, on Ubuntu. I believe the arguments are correctly laid out below to capture from two independent streams, and encode them both into the output MP4 file.
Edit :
I can simplify the question a bit, now.
ALSA buffer overrun (or underrun ?) is induced by the unreliable/noisy audio source. For instance, if ffmpeg captures the beginning of tape playback, this causes "buffer xrun" far beyond when the tape gets up to speed and playback should be normal.
It is interesting that the bitrate shown in the ffmpeg log shoots up higher than normal when it’s producing a garbage output ! (Is this bitrate a sum of of audio and video bitrates ?)
I’ve tried a couple of audio encoding codecs, and had the same problem.

ffmpeg’s detection of the ALSA stream is seemingly goofed up by the inconsistencies of the tape. In the failure case, only short blips of the tapes audio exist in the output MP4. The audio bitrate of the output file is less than 10 kbps, averaged out across the whole file. The output video seems to be fine, even though the low frames-per-second in the failure case log below.
The audio and video streams can be captured fine for short amounts of time before a source error occurs ; this provides the success case log. The failure case log was created by intentionally making an error in the source streams — turning on the camera makes a brief noisy signal.
Is there a setting that needs to be forced to keep ffmpeg recording the audio stream, even when the tape is blank or noisy ?
Could it be that the libfdk_aac audio encoder is tripped up by the low quality source ?

ffmpeg conversion .dav to any video files
22 février 2017, par Marcello GalvãoI am trying for days to convert
.davfile (file generated by dvrs [image recorders]). I have tried several variations withffmpegand can not succeed.Command and console output :
$ ffmpeg -i input.dav -codec:v libx264 -crf 23 -preset medium -codec:a libfdk_aac -vbr 4 -movflags faststart -vf scale=-1:720,format=yuv420p output.mp4

Codec AVOption vbr (VBR mode (1-5)) specified for output file #0 (output.mp4) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
