avcodec/smacker : Use unsigned for prediction values
26 juin 2020, par Andreas Rheinhardtavcodec/smacker : Use unsigned for prediction values
Up until now, the Smacker decoder has pretended that the prediction
values are signed in code like 'pred[0] += (unsigned)sign_extend(val, 16)'
(the cast has been added to this code later to fix undefined behaviour).
This has been even done in case the PCM format is u8.Yet in case of 8/16 bit samples, only the lower 8/16 bit of the predicition
values are ever used, so one can just as well just use unsigned and
remove the sign extensions. This is what this commit does.For GCC 9 the time for one call to smka_decode_frame() for the sample from
ticket #2425 decreased from 1709043 to 1693619 decicycles ; for Clang 9
it went up from 1355273 to 1369089 decicycles.Reviewed-by : Paul B Mahol <onemda@gmail.com>

How to send AVPacket through a QTcpSocket.write() with all of its data ?
24 juin 2024, par CottonBudsI want to send an AVPacket though a QTcpSocket.write() I tried to cast the avpacket pointer to an char * but it only shows 8 bytes of the avpacket and without the avpacket.data.




here is my code


void DisplayStreamServer::sendDataToClient(AVPacket* packet) {
 if (client == nullptr) {
 return;
 }


 client->write((char*) packet);
 client->waitForBytesWritten();

 av_packet_unref(packet);
 av_packet_free(&packet);
}


I can see that my packet.data has data inside it using the visual studio memory viewer. but it seems like when i convert the packet to char * the data is not included

libavutil/hwcontext_qsv : fix a bug for mapping vaapi frame to qsv
16 novembre 2021, par nyanmisakalibavutil/hwcontext_qsv : fix a bug for mapping vaapi frame to qsv
The data stored in data[3] in VAAPI AVFrame is VASurfaceID while
the data stored in pair->first is the pointer of VASurfaceID, so
we need to do cast to make following commandline works :ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 \
hwaccel_output_format vaapi -i input.264 \
vf "hwmap=derive_device=qsv,format=qsv" -c:v h264_qsv output.264Signed-off-by : nyanmisaka <nst799610810@gmail.com>
