From cdae7653cc243584b963716065a404f1e0665d0f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C3=ABl=20Carr=C3=A9?= Date: Mon, 21 Dec 2009 11:54:06 +0100 Subject: [PATCH] Increase avcodec encoding output buffer size Make some room for potential headers, You can now output VLC_CODEC_BMP We use the same arbitrary value of 200 bytes than ffmpeg.c Note: if we can ask FFmpeg to output RGBA (32bpp) or RGB48 (48bpp) then the multiplier should be increased to 4 or 6 (needs to be investigated) Pointed-out-by: ivoire --- modules/codec/avcodec/encoder.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/modules/codec/avcodec/encoder.c b/modules/codec/avcodec/encoder.c index 87ce339a2e..bc18c378b6 100644 --- a/modules/codec/avcodec/encoder.c +++ b/modules/codec/avcodec/encoder.c @@ -433,7 +433,10 @@ int OpenEncoder( vlc_object_t *p_this ) p_enc->fmt_in.video.i_sar_num, p_enc->fmt_in.video.i_sar_den, 1 << 30 ); - p_sys->i_buffer_out = p_context->height * p_context->width * 3; + p_sys->i_buffer_out = p_context->height * p_context->width + * 3 /* Assume 24bpp maximum */ + + 200; /* some room for potential headers (such as BMP) */ + if( p_sys->i_buffer_out < FF_MIN_BUFFER_SIZE ) p_sys->i_buffer_out = FF_MIN_BUFFER_SIZE; p_sys->p_buffer_out = malloc( p_sys->i_buffer_out ); -- 2.39.2
