Properties

ac 

“ac” gint

set number of audio channels (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 0

apply-phase-inv 

“apply-phase-inv” gboolean

Apply intensity stereo phase inversion (Private codec option)

Flags : Read / Write

Default value : true

ar 

“ar” gint

set audio sampling rate (in Hz) (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 0

audio-service-type 

“audio-service-type” avcodeccontext-audio-service-type *

audio service type (Generic codec option, might have no effect)

Flags : Read / Write

Default value : ma (0)

bitrate 

“bitrate” gint

set bitrate (in bits/s) (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 0

bitrate-tolerance 

“bitrate-tolerance” gint

Set video bitrate tolerance (in bits/s). In 1-pass mode, bitrate tolerance specifies how far ratecontrol is willing to deviate from the target average bitrate value. This is not related to minimum/maximum bitrate. Lowering tolerance too much has an adverse effect on quality. (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 4000000

bufsize 

“bufsize” gint

set ratecontrol buffer size (in bits) (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 0

compression-level 

“compression-level” gint

(null) (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 10

cutoff 

“cutoff” gint

set cutoff bandwidth (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 0

debug 

“debug” avcodeccontext-debug *

print specific debug info (Generic codec option, might have no effect)

Flags : Read / Write

Default value : (none)

dump-separator 

“dump-separator” gchararray

set information dump field separator (Generic codec option, might have no effect)

Flags : Read / Write

Default value : NULL

err-detect 

“err-detect” avcodeccontext-err-detect *

set error detection flags (Generic codec option, might have no effect)

Flags : Read / Write

Default value : (none)

export-side-data 

“export-side-data” avcodeccontext-export-side-data *

Export metadata as side data (Generic codec option, might have no effect)

Flags : Read / Write

Default value : (none)

flags 

“flags” avcodeccontext-flags *

(null) (Generic codec option, might have no effect)

Flags : Read / Write

Default value : (none)

flags2 

“flags2” avcodeccontext-flags2 *

(null) (Generic codec option, might have no effect)

Flags : Read / Write

Default value : (none)

frame-size 

“frame-size” gint

(null) (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 0

global-quality 

“global-quality” gint

(null) (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 0

max-pixels 

“max-pixels” gint64

Maximum number of pixels (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 2147483647

max-samples 

“max-samples” gint64

Maximum number of samples (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 2147483647

maxrate 

“maxrate” gint64

maximum bitrate (in bits/s). Used for VBV together with bufsize. (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 0

minrate 

“minrate” gint64

minimum bitrate (in bits/s). Most useful in setting up a CBR encode. It is of little use otherwise. (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 0

opus-delay 

“opus-delay” gfloat

Maximum delay in milliseconds (Private codec option)

Flags : Read / Write

Default value : 360

strict 

“strict” avcodeccontext-strict *

how strictly to follow the standards (Generic codec option, might have no effect)

Flags : Read / Write

Default value : normal (0)

thread-type 

“thread-type” avcodeccontext-thread-type *

select multithreading type (Generic codec option, might have no effect)

Flags : Read / Write

Default value : slice+frame

threads 

“threads” avcodeccontext-threads *

set the number of threads (Generic codec option, might have no effect)

Flags : Read / Write

Default value : unknown (1)

ticks-per-frame 

“ticks-per-frame” gint

(null) (Generic codec option, might have no effect)

Flags : Read / Write

Default value : 1

trellis 

“trellis” gint

rate-distortion optimal quantization (Generic codec option, might have no effect)
